2011-03-14MIPS, Perf-events: Work with the new PMU interfaceDeng-Cheng Zhu
This is the MIPS part of the following commits by Peter Zijlstra: - a4eaf7f14675cb512d69f0c928055e73d0c6d252 perf: Rework the PMU methods Replace pmu::{enable,disable,start,stop,unthrottle} with pmu::{add,del,start,stop}, all of which take a flags argument. The new interface extends the capability to stop a counter while keeping it scheduled on the PMU. We replace the throttled state with the generic stopped state. This also allows us to efficiently stop/start counters over certain code paths (like IRQ handlers). It also allows scheduling a counter without it starting, allowing for a generic frozen state (useful for rotating stopped counters). The stopped state is implemented in two different ways, depending on how the architecture implemented the throttled state: 1) We disable the counter: a) the pmu has per-counter enable bits, we flip that b) we program a NOP event, preserving the counter state 2) We store the counter state and ignore all read/overflow events For MIPSXX, the stopped state is implemented in the way of 1.b as above. - 33696fc0d141bbbcb12f75b69608ea83282e3117 perf: Per PMU disable Changes perf_disable() into perf_pmu_disable(). - 24cd7f54a0d47e1d5b3de29e2456bfbd2d8447b7 perf: Reduce perf_disable() usage Since the current perf_disable() usage is only an optimization, remove it for now.

2011-03-14MIPS, Perf-events: Work with irq_workDeng-Cheng Zhu
This is the MIPS part of the following commit by Peter Zijlstra: - e360adbe29241a0194e10e20595360dd7b98a2b3 irq_work: Add generic hardirq context callbacks Provide a mechanism that allows running code in IRQ context. It is most useful for NMI code that needs to interact with the rest of the system -- like wakeup a task to drain buffers. Perf currently has such a mechanism, so extract that and provide it as a generic feature, independent of perf so that others may also benefit. The IRQ context callback is generated through self-IPIs where possible, or on architectures like powerpc the decrementer (the built-in timer facility) is set to generate an interrupt immediately. Architectures that don't have anything like this get to do with a callback from the timer tick. These architectures can call irq_work_run() at the tail of any IRQ handlers that might enqueue such work (like the perf IRQ handler) to avoid undue latencies in processing the work. For MIPSXX, we need to call irq_work_run() at the tail of the perf IRQ handler as described above.

These settings come from a vendor; I remember builds from Lemote branch requiring a "console=tty" override in order to get a working console.

2011-03-14MIPS, Tracing: Fix set_graph_function of function graph tracerWu Zhangjin
trace.func should be set to the recorded ip of the mcount calling site in the __mcount_loc section to filter the function entries configured through the tracing/set_graph_function interface, but before, this is set to the self_ra(the return address of mcount), which has made set_graph_function not work as expected. This fixes it via calculating the right recorded ip in the __mcount_loc section and assign it to trace.func.

2011-03-14MIPS, Tracing: Clean up prepare_ftrace_return()Wu Zhangjin
The old prepare_ftrace_return() for MIPS is confused and have introduced some problem. This patch cleans up the names of the arguments, variables and related functions. For MIPS, the 2nd argument of prepare_ftrace_return() is not really the 'selfpc' described in ftrace-design.txt but instead it is the self return address. This did break the compatibility of the generic interface but really reduced one unneeded calculation for to get the current function name, the parent return address and the self return address are enough, no need to tranform the self return address to the self address. But set_graph_function of function graph tracer is an exception, it does need the 2nd argument of prepare_ftrace_return() as 'selfpc', for it will use 'selfpc' to match user's configuration of function graph entries, but in reality, it doesn't need the 'selfpc' but the recorded ip address of the mcount calling site in the __mcount_loc section. So, the 2nd argument of prepare_ftrace_return() is not important, the real requirement is the right recorded ip address should be calculated and assign to trace.func, this will be fixed in the next patches.

2011-03-14MIPS, Tracing: Substitute in_kernel_space() for in_module()Wu Zhangjin
The old in_module() may not work in some situations(e.g. when module & kernel are in the same address space when CONFIG_MAPPED_KERNEL=y), The in_kernel_space() is more generic and it is also easy to be implemented via cloning the existing core_kernel_text(), so, replace the in_module() with in_kernel_space().

2011-03-10powerpc/iseries: Fix early init access to lppacaBenjamin Herrenschmidt
The combination of commit 8154c5d22d91cd16bd9985b0638c8957e4688d0e and 93c22703efa72c7527dbd586d1951c1f4a85fd70 Broke boot on iSeries. The problem is that iSeries very early boot code, which generates the device-tree and runs before our normal early initializations does need access the lppaca's very early, before the PACA array is initialized, and in fact even before the boot PACA has been initialized (it contains all 0's at this stage). However, the first patch above makes that code use the new llpaca_of(cpu) accessor, which itself is changed by the second patch to use the PACA array. We fix that by reverting iSeries to directly dereferencing the array. In addition, we fix all iterators in the iSeries code to always skip CPU whose number is above 63 which is the maximum size of that array and the maximum number of supported CPUs on these machines. Additionally, we make sure the boot_paca is properly initialized in our early startup code. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2011-03-04ARM: S3C64XX: Fix keypad setup to configure correct number of rowsBen Dooks
The call to s3c_gpio_cfgrange_nopull() takes a size and base but this looks like it is trying to do base and end. This means it is configuring too many GPIOs and on the case of the Cragganmore means we're seeing an overflow of the ROW pins causing problems with the keyboard driver.

2011-03-04ARM: S3C2440: Fix usage gpio bank j pin definitions on GTA02Lars-Peter Clausen
The gta02 header file still uses the old S3C2410_GPJx defines instead of the S3C2410_GPJ(x) macro. Since the S3C2410_GPJx defines have already been removed this causes the following build failure: sound/soc/samsung/neo1973_wm8753.c: In function 'lm4853_set_spk': sound/soc/samsung/neo1973_wm8753.c:259: error: 'S3C2440_GPJ2' undeclared (first use in this function) sound/soc/samsung/neo1973_wm8753.c:259: error: (Each undeclared identifier is reported only once sound/soc/samsung/neo1973_wm8753.c:259: error: for each function it appears in.) sound/soc/samsung/neo1973_wm8753.c: In function 'lm4853_get_spk': sound/soc/samsung/neo1973_wm8753.c:267: error: 'S3C2440_GPJ2' undeclared (first use in this function) sound/soc/samsung/neo1973_wm8753.c: In function 'lm4853_event': sound/soc/samsung/neo1973_wm8753.c:276: error: 'S3C2440_GPJ1' undeclared (first use in this function) sound/soc/samsung/neo1973_wm8753.c: At top level: sound/soc/samsung/neo1973_wm8753.c:439: error: 'S3C2440_GPJ2' undeclared here (not in a function) sound/soc/samsung/neo1973_wm8753.c:440: error: 'S3C2440_GPJ1' undeclared here (not in a function) This patches fixes the issue by doing a s,S3C2410_GPJ([\d]+),S3C2410_GPJ(\1),g on the file.

2011-03-04ARM: S5P64X0: Fix number of GPIO lines in Bank FBanajit Goswami
This patch modifies the number of total GPIO lines for Bank F for Samsung S5P6440 and S5P6450 SoCs from 2 to 16. This is necessary as the GPIO lines from 0 to 13 are reserved and only lines 14 and 15 are used. As during initialization, the line number starts at 0, putting 2 does not solve the intended purpose.

2011-03-04ARM: S3C2440: Select missing S3C_DEV_USB_HOST on GTA02Lars-Peter Clausen
The gta02 mach file references the ohci device. So we need to select S3C_DEV_USB_HOST to have the device available. This fixes the following linker errors: arch/arm/mach-s3c2440/built-in.o: In function 'gta02_machine_init': mach-gta02.c:(.init.text+0x370): undefined reference to 's3c_ohci_set_platdata' arch/arm/mach-s3c2440/built-in.o:(.init.data+0xac): undefined reference to 's3c_device_ohci' Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
