Here, we wrap calls to desc->handler() in an inline function, desc_handle_irq(). This reduces the size of Thomas' patch since the changes become more localised.

Architecture platforms with a very sparse physical address space would likely want to select this option. For those architecture platforms that don't select the option, the code generated is equivalent to SPARSEMEM currently in -mm. I'll be posting a patch on ia64 ml which uses this new SPARSEMEM feature. ARCH_SPARSEMEM_EXTREME makes mem_section a one dimensional array of pointers to mem_sections. This two level layout scheme is able to achieve smaller memory requirements for SPARSEMEM with the tradeoff of an additional shift and load when fetching the memory section. The current SPARSEMEM -mm implementation is a one dimensional array of mem_sections which is the default SPARSEMEM configuration. The patch attempts isolates the implementation details of the physical layout of the sparsemem section array. ARCH_SPARSEMEM_EXTREME depends on 64BIT and is by default boolean false. I've boot tested under aim load ia64 configured for ARCH_SPARSEMEM_EXTREME. I've also boot tested a 4 way Opteron machine with !ARCH_SPARSEMEM_EXTREME and tested with aim.

It happens > if the virtual address for hugetlb mmap is recycled from previously used > normal page mmap. free_pgtables() might not scrub the pmd entry on > munmap and hugetlb_prefault skips on any pmd presence regardless what type > it is. Unless I am missing something, it seems more correct to place the check inside huge_pte_alloc() to prevent a the same bug wherever a huge pte is allocated.

It now collect all the pte page at the time of munmap. It used to only collect page table pages when entire one pgd can be freed and left with staled pte pages. Not anymore with 2.6.13. This function will never be called and We should turn it into a BUG_ON. I also spotted two problems here, not Adam's fault :-) (1) in huge_pte_alloc(), it looks like a bug to me that pud is not checked before calling pmd_alloc() (2) in hugetlb_clean_stale_pgtable(), it also missed a call to pmd_free_tlb. I think a tlb flush is required to flush the mapping for the page table itself when we clear out the pmd pointing to a pte page. However, since hugetlb_clean_stale_pgtable() is never called, so it won't trigger the bug.

The timer has implementation dependent timeout frequencies that can be configured by software. One the first Watchdog timeout we get a critical exception. It is left to board specific code to determine what should happen at this point. If nothing is done and another timeout period expires the processor may attempt to reset the machine. Command line parameters: wdt=0 : disable watchdog (default) wdt=1 : enable watchdog wdt_period=N : N sets the value of the Watchdog Timer Period. The Watchdog Timer Period meaning is implementation specific. Check User Manual for the processor for more details. This patch is based off of work done by Takeharu Kato.

Sep 2005 15:55:35 -0700 Subject: [PATCH] ppc32: add phy excluded features to ocp_func_emac_data This patch adds a field to struct ocp_func_emac_data that allows platform-specific unsupported PHY features to be passed in to the ibm_emac ethernet driver. This patch also adds some logic for the Bamboo eval board to populate this field based on the dip switches on the board. This is a workaround for the improperly biased RJ-45 sockets on the Rev. 0 Bamboo.

MPC83xx Adds support for the two PCI busses on MPC83xx and the MPC834x SYS/PIBS reference board. The code initializes PCI inbound/outbound windows, allocates and registers PCI memory/io space. Be aware that setup of the PCI buses on the PIBs board is expected to be done by the firmware.

Change the units of the parameter of do_event_scan_all_cpus() to milliseconds from jiffies. The return value of rtas_extended_busy_delay_time() was incorrectly being used as a jiffies value (it is actually milliseconds), which is fixed by using the value as a parameter to msleep_interruptible(). Also, use rtas_extended_busy_delay_time() in another case where similar logic is duplicated.

The effect is 132 bytes less of stack used by the typical do_page_fault() invocation - resulting in a denser cache-layout. (Another minor effect is that in case of kernel crashes that come from a pagefault, we add less space to the already existing frame, giving the crash functions a slightly higher chance to do their stuff without overflowing the stack.)

This uses the memory descriptor size obtained from EFI to iterate over the memory map entries during boot. This enables the removal of an x86 specific pad (and ifdef) in the EFI header. I also couldn't stomach the broken up nature of the function to put EFI runtime calls into virtual mode any longer so I fixed that up a bit as well. For reference, this patch only impacts x86.

However, the emulation ignored the TF bit, so the hardware debug interrupt was not invoked after such an emulated instruction (and the DOS debugger missed it). This patch fixes the problem by emulating the hardware debug interrupt as the last action before control is returned to the VM86 program.

In kexec on panic case parameter segment might well be loaded beyond kernel image and might not be addressable by early boot page tables. o This case might hit in the scenario where user has reserved a chunk of memory for second kernel, for example 16MB to 64MB, and has also built second kernel for physical memory location 16MB. In this case kexec has no choice but to load the parameter segment at a higher address than new kernel image at safe location where new kernel does not stomp it. o Though problem should automatically go away once relocatable kernel for i386 is in place and kexec can determine the location of new kernel at run time and load parameter segment at lower address than kernel image. But till then this patch can go in (assuming it does not break something else). o This patch moves up the boot parameter saving code. Now boot parameters are copied out in protected mode before page tables are initialized. This will ensure that parameter segment is always addressable irrespective of its physical location.

I've modified platform check code and removed unnecessary OEM table parsing for newer systems that don't use OEM information during boot. Parsing the table in fact is causing problems, and the platform doesn't get recognized. The patch only affects the ES7000 subach.

Use cr/dr accessor functions. Also, a potential bugfix. Also, some CR accessors really should be volatile. Reads from CR0 (numeric state may change in an exception handler), writes to CR4 (flipping CR4.TSD) and reads from CR2 (page fault) prevent instruction re-ordering. I did not add memory clobber to CR3 / CR4 / CR0 updates, as it was not there to begin with, and in no case should kernel memory be clobbered, except when doing a TLB flush, which already has memory clobber. I noticed that page invalidation does not have a memory clobber. I can't find a bug as a result, but there is definitely a potential for a bug here: #define __flush_tlb_single(addr) \ __asm__ __volatile__("invlpg %0": :"m" (*(char *) addr)) Signed-off-by: Zachary Amsden Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- arch/i386/kernel/cpu/common.c | 12 ++++++------ arch/i386/kernel/cpu/cpufreq/longhaul.c | 12 +++--------- arch/i386/kernel/cpu/cyrix.c | 6 +----- arch/i386/kernel/efi.c | 4 ++-- arch/i386/kernel/machine_kexec.c | 8 +------- arch/i386/kernel/process.c | 16 ++++++---------- arch/i386/kernel/smp.c | 2 +- arch/i386/mm/fault.c | 6 +++--- arch/i386/mm/pageattr.c | 2 +- arch/i386/power/cpu.c | 16 ++++++++-------- include/asm-i386/agp.h | 2 +- include/asm-i386/bugs.h | 5 ++++- include/asm-i386/processor.h | 22 +++++++++------------- include/asm-i386/system.h | 28 +++++++++++++++++++++++++--- include/asm-i386/xor.h | 26 +++++++++++++------------- 15 files changed, 84 insertions(+), 83 deletions(-) (limited to 'arch') diff --git a/arch/i386/kernel/cpu/common.c b/arch/i386/kernel/cpu/common.c index 4553ffd94b1f..361f2e7ccb12 100644 --- a/arch/i386/kernel/cpu/common.c +++ b/arch/i386/kernel/cpu/common.c @@ -642,12 +642,12 @@ void __devinit cpu_init(void) asm volatile ("xorl %eax, %eax; movl %eax, %fs; movl %eax, %gs"); /* Clear all 6 debug registers: */ - -#define CD(register) set_debugreg(0, register) - - CD(0); CD(1); CD(2); CD(3); /* no db4 and db5 */; CD(6); CD(7); - -#undef CD + set_debugreg(0, 0); + set_debugreg(0, 1); + set_debugreg(0, 2); + set_debugreg(0, 3); + set_debugreg(0, 6); + set_debugreg(0, 7); /* * Force FPU initialization: diff --git a/arch/i386/kernel/cpu/cpufreq/longhaul.c b/arch/i386/kernel/cpu/cpufreq/longhaul.c index 04e3563da4fe..bf02b5026e62 100644 --- a/arch/i386/kernel/cpu/cpufreq/longhaul.c +++ b/arch/i386/kernel/cpu/cpufreq/longhaul.c @@ -64,8 +64,6 @@ static int dont_scale_voltage; #define dprintk(msg...) cpufreq_debug_printk(CPUFREQ_DEBUG_DRIVER, "longhaul", msg) -#define __hlt() __asm__ __volatile__("hlt": : :"memory") - /* Clock ratios multiplied by 10 */ static int clock_ratio[32]; static int eblcr_table[32]; @@ -168,11 +166,9 @@ static void do_powersaver(union msr_longhaul *longhaul, outb(0xFE,0x21); /* TMR0 only */ outb(0xFF,0x80); /* delay */ - local_irq_enable(); - - __hlt(); + safe_halt(); wrmsrl(MSR_VIA_LONGHAUL, longhaul->val); - __hlt(); + halt(); local_irq_disable(); @@ -251,9 +247,7 @@ static void longhaul_setstate(unsigned int clock_ratio_index) bcr2.bits.CLOCKMUL = clock_ratio_index; local_irq_disable(); wrmsrl (MSR_VIA_BCR2, bcr2.val); - local_irq_enable(); - - __hlt(); + safe_halt(); /* Disable software clock multiplier */ rdmsrl (MSR_VIA_BCR2, bcr2.val); diff --git a/arch/i386/kernel/cpu/cyrix.c b/arch/i386/kernel/cpu/cyrix.c index ba4b01138c8f..ff87cc22b323 100644 --- a/arch/i386/kernel/cpu/cyrix.c +++ b/arch/i386/kernel/cpu/cyrix.c @@ -132,11 +132,7 @@ static void __init set_cx86_memwb(void) setCx86(CX86_CCR2, getCx86(CX86_CCR2) & ~0x04); /* set 'Not Write-through' */ cr0 = 0x20000000; - __asm__("movl %%cr0,%%eax\n\t" - "orl %0,%%eax\n\t" - "movl %%eax,%%cr0\n" - : : "r" (cr0) - :"ax"); + write_cr0(read_cr0() | cr0); /* CCR2 bit 2: lock NW bit and set WT1 */ setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x14 ); } diff --git a/arch/i386/kernel/efi.c b/arch/i386/kernel/efi.c index 850648ae8305..921fdb15fc9b 100644 --- a/arch/i386/kernel/efi.c +++ b/arch/i386/kernel/efi.c @@ -79,7 +79,7 @@ static void efi_call_phys_prelog(void) * directory.

Introduce the serialize macro to serialize processor state. Why the microcode update needs it I am not quite sure, since wrmsr() is already a serializing instruction, but it is a microcode update, so I will keep the semantic the same, since this could be a timing workaround. As far as I can tell, this has always been there since the original microcode update source.

This change encapsulates descriptor and task register management. Also, it is possible to improve assembler generation in two cases; savesegment may store the value in a register instead of a memory location, which allows GCC to optimize stack variables into registers, and MOV MEM, SEG is always a 16-bit write to memory, making the casting in math-emu unnecessary.

Since the four PDPEs must always be present in an active root, and the kernel PDPE is never updated, we are safe even from SMIs and interrupts / NMIs using task gates (which reload CR3). Actually, much of this is moot, since the user PDPEs are never updated either, and the only usage of task gates is by the doublefault handler. It appears the only place PGDs get updated in PAE mode is in init_low_mappings() / zap_low_mapping() for initial page table creation and recovery from ACPI sleep state, and these sites are safe by inspection. Getting rid of the cmpxchg8b saves code space and 720 cycles in pgd_alloc on P4.

Originally, these diffs were much greater, but recent cleanups in Linux have already done much of the cleanup. I added some explanatory comments in places where the reasoning behind certain tests is rather subtle. Also, in traps.c, we can skip the user_mode check in handle_BUG(). The reason is, there are only two call chains - one via die_if_kernel() and one via do_page_fault(), both entering from die(). Both of these paths already ensure that a kernel mode failure has happened. Also, the original check here, if (user_mode(regs)) was insufficient anyways, since it would not rule out BUG faults from V8086 mode execution. Saving the %ss segment in show_regs() rather than assuming a fixed value also gives better information about the current kernel state in the register dump.

Making this explicit in C code is more clear. This pushf/popf pair was added as a bugfix for leaking IOPL to unprivileged processes when using sysenter/sysexit based system calls (sysexit does not restore flags). When requesting an IOPL change in sys_iopl(), it is just as easy to change the current flags and the flags in the stack image (in case an IRET is required), but there is no reason to force an IRET if we came in from the SYSENTER path. This change is the minimal solution for supporting a paravirtualized Linux kernel that allows user processes to run with I/O privilege. Other solutions require radical rewrites of part of the low level fault / system call handling code, or do not fully support sysenter based system calls. Unfortunately, this added one field to the thread_struct. But as a bonus, on P4, the fastest time measured for switch_to() went from 312 to 260 cycles, a win of about 17% in the fast case through this performance critical path.

This give debug code a chance to a) catch watchdog timeouts and b) possibly allow the system to continue, realizing that the time out may be due to debugger activities such as single stepping which is usually done with "other" cpus held.

This helps complete the encapsulation of updates to page tables (or pages about to become page tables) into accessor functions rather than using memcpy() to duplicate them. This is both generally good for consistency and also necessary for running in a hypervisor which requires explicit updates to page table entries. The new function is: clone_pgd_range(pgd_t *dst, pgd_t *src, int count); dst - pointer to pgd range anwhere on a pgd page src - "" count - the number of pgds to copy. dst and src can be on the same page, but the range must not overlap and must not cross a page boundary. Note that I ommitted using this call to copy pgd entries into the software suspend page root, since this is not technically a live paging structure, rather it is used on resume from suspend. CC'ing Pavel in case he has any feedback on this. Thanks to Chris Wright for noticing that this could be more optimal in PAE compiles by eliminating the memset.

This breaks things which do for_each_cpu iterations early during boot. So, define cpu_possible_map as a bitmap with NR_CPUS bits populated. This was triggered by a patch i'm working on which does alloc_percpu before bringing up secondary processors. From: Alexander Nyberg i386-boottime-for_each_cpu-broken.patch i386-boottime-for_each_cpu-broken-fix.patch The SMP version of __alloc_percpu checks the cpu_possible_map before allocating memory for a certain cpu. With the above patches the BSP cpuid is never set in cpu_possible_map which breaks CONFIG_SMP on uniprocessor machines (as soon as someone tries to dereference something allocated via __alloc_percpu, which in fact is never allocated since the cpu is not set in cpu_possible_map).

In fact, using PTRACE_SYSCALL means stopping child execution twice, on entry and on exit, and each time you also have two context switches; with SYSEMU you avoid the 2nd stop and so save two context switches per syscall. Also, some architectures don't have support in the host for changing the syscall number via ptrace(), which is currently needed to skip syscall execution (UML turns any syscall into getpid() to avoid it being executed on the host). Fixing that is hard, while SYSEMU is easier to implement. * This version of the patch includes some suggestions of Jeff Dike to avoid adding any instructions to the syscall fast path, plus some other little changes, by myself, to make it work even when the syscall is executed with SYSENTER (but I'm unsure about them). It has been widely tested for quite a lot of time. * Various fixed were included to handle the various switches between various states, i.e. when for instance a syscall entry is traced with one of PT_SYSCALL / _SYSEMU / _SINGLESTEP and another one is used on exit. Basically, this is done by remembering which one of them was used even after the call to ptrace_notify(). * We're combining TIF_SYSCALL_EMU with TIF_SYSCALL_TRACE or TIF_SINGLESTEP to make do_syscall_trace() notice that the current syscall was started with SYSEMU on entry, so that no notification ought to be done in the exit path; this is a bit of a hack, so this problem is solved in another way in next patches. * Also, the effects of the patch: "Ptrace - i386: fix Syscall Audit interaction with singlestep" are cancelled; they are restored back in the last patch of this series. Detailed descriptions of the patches doing this kind of processing follow (but I've already summed everything up). * Fix behaviour when changing interception kind #1. In do_syscall_trace(), we check the status of the TIF_SYSCALL_EMU flag only after doing the debugger notification; but the debugger might have changed the status of this flag because he continued execution with PTRACE_SYSCALL, so this is wrong. This patch fixes it by saving the flag status before calling ptrace_notify(). * Fix behaviour when changing interception kind #2: avoid intercepting syscall on return when using SYSCALL again. A guest process switching from using PTRACE_SYSEMU to PTRACE_SYSCALL crashes. The problem is in arch/i386/kernel/entry.S. The current SYSEMU patch inhibits the syscall-handler to be called, but does not prevent do_syscall_trace() to be called after this for syscall completion interception. The appended patch fixes this. It reuses the flag TIF_SYSCALL_EMU to remember "we come from PTRACE_SYSEMU and now are in PTRACE_SYSCALL", since the flag is unused in the depicted situation. * Fix behaviour when changing interception kind #3: avoid intercepting syscall on return when using SINGLESTEP. When testing 2.6.9 and the skas3.v6 patch, with my latest patch and had problems with singlestepping on UML in SKAS with SYSEMU. It looped receiving SIGTRAPs without moving forward. EIP of the traced process was the same for all SIGTRAPs. What's missing is to handle switching from PTRACE_SYSCALL_EMU to PTRACE_SINGLESTEP in a way very similar to what is done for the change from PTRACE_SYSCALL_EMU to PTRACE_SYSCALL_TRACE. I.e., after calling ptrace(PTRACE_SYSEMU), on the return path, the debugger is notified and then wake ups the process; the syscall is executed (or skipped, when do_syscall_trace() returns 0, i.e. when using PTRACE_SYSEMU), and do_syscall_trace() is called again. Since we are on the return path of a SYSEMU'd syscall, if the wake up is performed through ptrace(PTRACE_SYSCALL), we must still avoid notifying the parent of the syscall exit. Now, this behaviour is extended even to resuming with PTRACE_SINGLESTEP.

On this patch, I have some doubts: I wonder why we need to alter that way ptrace_disable(). I left the patch this way because it has been extensively tested, but I don't understand the reason. The current PTRACE_DETACH handling simply clears child->ptrace; actually this is not enough because entry.S just looks at the thread_flags; actually, do_syscall_trace checks current->ptrace but I don't think depending on that is good, at least for performance, so I think the clearing is done elsewhere. For instance, on PTRACE_CONT it's done, but doing PTRACE_DETACH without PTRACE_CONT is possible (and happens when gdb crashes and one kills it manually).

Rather than having a context switch to and from the userspace stub for each address space change, we write a number of operations to the stub data page and invoke a different stub which loops over them and executes them all in one go. The operations are stored as [ system call number, arg1, arg2, ... ] tuples. The set is terminated by a system call number of 0. Single operations, i.e. page faults, are handled in the old way, since that is slightly more efficient. For a kernel build, a minority (~1/4) of the operations are part of a set. These sets averaged ~100 in length, so for this quarter, the context switching overhead is greatly reduced.

The driver breaks a struct request into IO requests to the host, based on the hardware segments in the request and on any COW blocks covered by the request. The ubd IO thread is gone, since there is now an equivalent thread in the AIO module. There is provision for multiple outstanding requests now. Requests aren't retired until all pieces of it have been completed. The AIO requests have a shared count, which is decremented as IO operations come in until it reaches 0. This can be possibly moved to the request struct - haven't looked at this yet.

Also it changes the initialization of proc_mm and ptrace_faultinfo slightly, to ease forcing SKAS0 on a patched host. Forcing UML to run without /proc/mm or PTRACE_FAULTINFO by cmdline parameter can be implemented with a setup resetting the related variable.

Stub now checks syscalls retval and aborts execution of syscall list, if retval != expected retval. run_syscall_stub prints the data of the failed syscall, using the data pointer and retval written by the stub to the beginning of the stack. one_syscall_stub is removed, to simplify code, because only some instructions are saved by one_syscall_stub, no host-syscall. Using the stub with additional data (modify_ldt via stub) is prepared also.

That function gets called two times for each pfault notification. Once with a subcode of 0 to indicate that a real page is not available and once with a subcode of 0x80 to indicate that the page is present again. Since the two external interrupts can be delivered on two different cpus the order in which the two calls are made is unpredictable. It is possible that the subcode 0x80 interrupt is completed before the subcode 0x00 interrupt has done the wake_up() call. To avoid calling wake_up() on an already removed task structure proper task structure reference counting is needed. Increase the reference counter in the subcode 0x00 interrupt before setting pfault_wait to zero and return the reference after the wake_up call.

On POWER5, ERAT entries created in real mode have the class bit clear. So to avoid flushing kernel ERAT entries on each context switch, this patch inverts our usage of the class bit, setting it on user SLB entries and clearing it on kernel SLB entries.

To do this it multiplies the contents of the timer register with a large constant. The result is then divided by a large constant. Unfortunately the result of the first multiplication is often too large for the register to hold. The solution is to combine the two large constants to a single smaller constant at compile time. Then the timer value can be divided by single smaller constant without any overflow issues.

This is not recommended and could potentially cause chipset's to lockup, or cause missing interrupts. CONFIG_IRQ_BALANCE does this correctly, where it re-programs only when the interrupt is pending. The same needs to be done for /proc/irq handling as well. Otherwise user space irq balancers are really not doing the right thing. - Changed pending_irq_balance_cpumask to pending_irq_migrate_cpumask for lack of a generic name. - added move_irq out of IRQ_BALANCE, and added this same to X86_64 - Added new proc handler for write, so we can do deferred write at irq handling time. - Display of /proc/irq/XX/smp_affinity used to display CPU_MASKALL, instead it now shows only active cpu masks, or exactly what was set. - Provided a common move_irq implementation, instead of duplicating when using generic irq framework. Tested on i386/x86_64 and ia64 with CONFIG_PCI_MSI turned on and off. Tested UP builds as well. MSI testing: tbd: I have cards, need to look for a x-over cable, although I did test an earlier version of this patch. Will test in a couple days.

When enabled then per-CPU watchdog threads are started, which try to run once per second. If they get delayed for more than 10 seconds then a callback from the timer interrupt detects this condition and prints out a warning message and a stack dump (once per lockup incident).

At the moment, we get away with it, because hardirq.h isn't included in the oprofile code. I hit this as a bug when working with a patch which (indirectly) adds a #include of hardirq.h to oprofile. Regardless, the name collision is probably not a good idea, so this patch fixes it, renaming the oprofile function to op_nmi_exit(). It also renames the nmi_init() and nmi_timer_init() functions similarly, for consistency.

I have fixed a problem with the ia64 version of build_sched_domains(), but a similar fix still needs to be made to the generic build_sched_domains() in kernel/sched.c. The "dynamic sched domains" functionality has recently been merged into 2.6.13-rcN that sees the dynamic declaration of a cpu-exclusive (a.k.a. "isolated") cpuset and rebuilds the CPU Scheduler sched domains and sched groups to separate away the CPUs in this cpu-exclusive cpuset from the remainder of the non-isolated CPUs. This allows the non-isolated CPUs to completely ignore the isolated CPUs when doing load-balancing. Unfortunately, build_sched_domains() expects that a sched domain will include all the CPUs of each node in the domain, i.e., that no node will belong in both an isolated cpuset and a non-isolated cpuset. Declaring a cpuset that violates this presumption will produce flawed data structures and will oops the kernel. To trigger the problem (on a NUMA system with >1 CPUs per node): cd /dev/cpuset mkdir newcpuset cd newcpuset echo 0 >cpus echo 0 >mems echo 1 >cpu_exclusive I have fixed this shortcoming for ia64 NUMA (with multiple CPUs per node). A similar shortcoming exists in the generic build_sched_domains() (in kernel/sched.c) for NUMA, and that needs to be fixed also. The fix involves dynamically allocating sched_group_nodes[] and sched_group_allnodes[] for each invocation of build_sched_domains(), rather than using global arrays for these structures. Care must be taken to remember kmalloc() addresses so that arch_destroy_sched_domains() can properly kfree() the new dynamic structures.

Zero thus means no matches. 2) A match callback can return nonzero to stop the match checking. Bug: The count is incremented after we check for the nonzero return value, so it does not reflect the actual count. We could say this is intended, for some dumb reason, except that it means that a match on the first check returns zero--no matches--if the callback returns nonzero. Attached patch implements the count before calling the callback and thus before potentially short-circuiting.
