2021-08-26Merge tag 'drm/tegra/for-5.15-rc1' of ↵Dave Airlie
ssh://git.freedesktop.org/git/tegra/linux into drm-next drm/tegra: Changes for v5.15-rc1 The bulk of these changes is a more modern ABI that can be efficiently used on newer SoCs as well as older ones. The userspace parts for this are available here: - libdrm support: https://gitlab.freedesktop.org/tagr/drm/-/commits/drm-tegra-uabi-v8 - VAAPI driver: https://github.com/cyndis/vaapi-tegra-driver In addition, existing userspace from the grate reverse-engineering project has been updated to use this new ABI: - X11 driver: https://github.com/grate-driver/xf86-video-opentegra - 3D driver: https://github.com/grate-driver/grate Other than that, there's also support for display memory bandwidth management for various generations and a bit of cleanup.

2021-08-10gpu: host1x: Add option to skip firewall for a jobMikko Perttunen
The new UAPI will have its own firewall, and we don't want to run the firewall in the Host1x driver for those jobs. As such, add a parameter to host1x_job_alloc to specify if we want to skip the firewall in the Host1x driver.

2021-08-10gpu: host1x: Add support for syncpoint waits in CDMA pushbufferMikko Perttunen
Add support for inserting syncpoint waits in the CDMA pushbuffer. These waits need to be done in HOST1X class, while gather submitted by the application execute in engine class. Support is added by converting the gather list of job into a command list that can include both gathers and waits. When the job is submitted, these commands are pushed as the appropriate opcodes on the CDMA pushbuffer. Also supported are waits relative to the start of the job, which are useful for jobs doing multiple things with an engine that doesn't natively support pipelining. While at it, use 32-bit waits on chips that support them. Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-08-10gpu: host1x: Add job release callbackMikko Perttunen

2021-08-10gpu: host1x: Add no-recovery modeMikko Perttunen
Add a new property for jobs to enable or disable recovery i.e. CPU increments of syncpoints to max value on job timeout. This allows for a more solid model for hanged jobs, where userspace doesn't need to guess if a syncpoint increment happened because the job completed, or because job timeout was triggered. On job timeout, we stop the channel, NOP all future jobs on the channel using the same syncpoint, mark the syncpoint as locked and resume the channel from the next job, if any. The future jobs are NOPed, since because we don't do the CPU increments, the value of the syncpoint is no longer synchronized, and any waiters would become confused if a future job incremented the syncpoint. The syncpoint is marked locked to ensure that any future jobs cannot increment the syncpoint either, until the application has recognized the situation and reallocated the syncpoint.

2021-08-10gpu: host1x: Add DMA fence implementationMikko Perttunen
Add an implementation of dma_fences based on syncpoints. Syncpoint interrupts are used to signal fences. Additionally, after software signaling has been enabled, a 30 second timeout is started. If the syncpoint threshold is not reached within this period, the fence is signalled with an -ETIMEDOUT error code. This is to allow fences that would never reach their syncpoint threshold to be cleaned up. The timeout can potentially be removed in the future after job tracking code has been refactored.

2021-07-23memblock: make for_each_mem_range() traverse MEMBLOCK_HOTPLUG regionsMike Rapoport
Commit b10d6bca8720 ("arch, drivers: replace for_each_membock() with for_each_mem_range()") didn't take into account that when there is movable_node parameter in the kernel command line, for_each_mem_range() would skip ranges marked with MEMBLOCK_HOTPLUG. The page table setup code in POWER uses for_each_mem_range() to create the linear mapping of the physical memory and since the regions marked as MEMORY_HOTPLUG are skipped, they never make it to the linear map.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Will Deacon: "A pair of arm64 fixes for -rc3. The straightforward one is a fix to our firmware calling stub, which accidentally started corrupting the link register on machines with SVE. Since these machines don't really exist yet, it wasn't spotted in -next. The other fix is a revert-and-a-bit of a patch originally intended to allow PTE-level huge mappings for the VMAP area on 32-bit PPC 8xx. A side-effect of this change was that our pXd_set_huge() implementations could be replaced with generic dummy functions depending on the levels of page-table being used, which in turn broke the boot if we fail to create the linear mapping as a result of using these functions to operate on the pgd. Huge thanks to Michael Ellerman for modifying the revert so as not to regress PPC 8xx in terms of functionality. Anyway, that's the background and it's also available in the commit message along with Link tags pointing at all of the fun.

2021-07-21Revert "mm/pgtable: add stubs for {pmd/pub}_{set/clear}_huge"Jonathan Marek
This reverts commit c742199a014de23ee92055c2473d91fe5561ffdf. c742199a014d ("mm/pgtable: add stubs for {pmd/pub}_{set/clear}_huge") breaks arm64 in at least two ways for configurations where PUD or PMD folding occur: 1. We no longer install huge-vmap mappings and silently fall back to page-granular entries, despite being able to install block entries at what is effectively the PGD level. 2. If the linear map is backed with block mappings, these will now silently fail to be created in alloc_init_pud(), causing a panic early during boot. The pgtable selftests caught this, although a fix has not been forthcoming and Christophe is AWOL at the moment, so just revert the change for now to get a working -rc3 on which we can queue patches for 5.15. A simple revert breaks the build for 32-bit PowerPC 8xx machines, which rely on the default function definitions when the corresponding page-table levels are folded, since commit a6a8f7c4aa7e ("powerpc/8xx: add support for huge pages on VMAP and VMALLOC"), eg: powerpc64-linux-ld: mm/vmalloc.o: in function `vunmap_pud_range': linux/mm/vmalloc.c:362: undefined reference to `pud_clear_huge' To avoid that, add stubs for pud_clear_huge() and pmd_clear_huge() in arch/powerpc/mm/nohash/8xx.c as suggested by Christophe.

2021-07-21drivers/firmware: consolidate EFI framebuffer setup for all archesJavier Martinez Canillas
The register_gop_device() function registers an "efi-framebuffer" platform device to match against the efifb driver, to have an early framebuffer for EFI platforms. But there is already support to do exactly the same by the Generic System Framebuffers (sysfb) driver. This used to be only for X86 but it has been moved to drivers/firmware and could be reused by other architectures. Also, besides supporting registering an "efi-framebuffer", this driver can register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers on non-X86 EFI platforms. For example, on aarch64 these drivers can only be used with DT and doesn't have code to register a "simple-frambuffer" platform device when booting with EFI. For these reasons, let's remove the register_gop_device() duplicated code and instead move the platform specific logic that's there to sysfb driver.

2021-07-21drivers/firmware: move x86 Generic System Framebuffers supportJavier Martinez Canillas
The x86 architecture has generic support to register a system framebuffer platform device. It either registers a "simple-framebuffer" if the config option CONFIG_X86_SYSFB is enabled, or a legacy VGA/VBE/EFI FB device. But the code is generic enough to be reused by other architectures and can be moved out of the arch/x86 directory. This will allow to also support the simple{fb,drm} drivers on non-x86 EFI platforms, such as aarch64 where these drivers are only supported with DT.

2021-07-21bus: Make remove callback return voidUwe Kleine-König
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

2021-07-21PCI: endpoint: Make struct pci_epf_driver::remove return voidUwe Kleine-König
The driver core ignores the return value of pci_epf_device_remove() (because there is only little it can do when a device disappears) and there are no pci_epf_drivers with a remove callback. So make it impossible for future drivers to return an unused error code by changing the remove prototype to return void. The real motivation for this change is the quest to make struct bus_type::remove return void, too.

The DMA-BUF attachment statistics form a subset of the DMA-BUF sysfs statistics that recently merged to the drm-misc tree. They are not UABI yet since they have not merged to the upstream Linux kernel. Since there has been a reported a performance regression due to the overhead of sysfs directory creation/teardown during dma_buf_attach()/dma_buf_detach(), this patch deletes the DMA-BUF attachment statistics from sysfs.

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull more s390 updates from Vasily Gorbik: - Fix preempt_count initialization. - Rework call_on_stack() macro to add proper type handling and avoid possible register corruption. - More error prone "register asm" removal and fixes. - Fix syscall restarting when multiple signals are coming in. This adds minimalistic trampolines to vdso so we can return from signal without using the stack which requires pgm check handler hacks when NX is enabled. - Remove HAVE_IRQ_EXIT_ON_IRQ_STACK since this is no longer true after switch to generic entry. - Fix protected virtualization secure storage access exception handling. - Make machine check C handler always enter with DAT enabled and move register validation to C code. - Fix tinyconfig boot problem by avoiding MONITOR CALL without CONFIG_BUG. - Increase asm symbols alignment to 16 to make it consistent with compilers. - Enable concurrent access to the CPU Measurement Counter Facility. - Add support for dynamic AP bus size limit and rework ap_dqap to deal with messages greater than recv buffer. * tag 's390-5.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (41 commits) s390: preempt: Fix preempt_count initialization s390/linkage: increase asm symbols alignment to 16 s390: rename CALL_ON_STACK_NORETURN() to call_on_stack_noreturn() s390: add type checking to CALL_ON_STACK_NORETURN() macro s390: remove old CALL_ON_STACK() macro s390/softirq: use call_on_stack() macro s390/lib: use call_on_stack() macro s390/smp: use call_on_stack() macro s390/kexec: use call_on_stack() macro s390/irq: use call_on_stack() macro s390/mm: use call_on_stack() macro s390: introduce proper type handling call_on_stack() macro s390/irq: simplify on_async_stack() s390/irq: inline do_softirq_own_stack() s390/irq: simplify do_softirq_own_stack() s390/ap: get rid of register asm in ap_dqap() s390: rename PIF_SYSCALL_RESTART to PIF_EXECVE_PGSTE_RESTART s390: move restart of execve() syscall s390/signal: remove sigreturn on stack s390/signal: switch to using vdso for sigreturn and syscall restart ...
