2023-05-03drm/i915/guc: Fix error capture for virtual enginesJohn Harrison
GuC based register dumps in error capture logs were basically broken for virtual engines. This can be seen in igt@gem_exec_balancer@hang: [IGT] gem_exec_balancer: starting subtest hang [drm] GPU HANG: ecode 12:4:e1524110, in gem_exec_balanc [6388] [drm] GT0: GUC: No register capture node found for 0x1005 / 0xFEDC311D [drm] GPU HANG: ecode 12:4:00000000, in gem_exec_balanc [6388] [IGT] gem_exec_balancer: exiting, ret=0 The test causes a hang on both engines of a virtual engine context. The engine instance zero hang gets a valid error capture but the non-instance-zero hang does not. Fix that by scanning through the list of pending register captures when a hang notification for a virtual engine is received. That way, the hang can be assigned to the correct physical engine prior to starting the error capture process. So later on, when the error capture handler tries to find the engine register list, it looks for one on the correct engine. Also, sneak in a missing blank line before a comment in the node search code. v2: Fix null pointer deref on non-GuC platforms.

2023-05-03drm/i915/dsi: Use unconditional msleep() instead of intel_dsi_msleep()Hans de Goede
The intel_dsi_msleep() helper skips sleeping if the MIPI-sequences have a version of 3 or newer and the panel is in vid-mode. This is based on the big comment around line 730 which starts with "Panel enable/disable sequences from the VBT spec.", where the "v3 video mode seq" column does not have any wait t# entries. Checking the Windows driver shows that it does always honor the VBT delays independent of the version of the VBT sequences. Commit 6fdb335f1c9c ("drm/i915/dsi: Use unconditional msleep for the panel_on_delay when there is no reset-deassert MIPI-sequence") switched to a direct msleep() instead of intel_dsi_msleep() when there is no MIPI_SEQ_DEASSERT_RESET sequence, to fix the panel on an Acer Aspire Switch 10 E SW3-016 not turning on.

CPU transcoder mask is used to iterate over the available CPU transcoders in the macro for_each_cpu_transcoder(). The macro is broken on MTL and got highlighted when audio state was being tracked for each transcoder added in [1].

2023-05-03drm/i915/guc: Actually return an error if GuC version range check failsJohn Harrison
Dan Carpenter pointed out that 'err' was not being set in the case where the GuC firmware version range check fails. Fix that. Note that while this is a bug fix for a previous patch (see Fixes tag below). It is an exceedingly low risk bug. The range check is asserting that the GuC firmware version is within spec. So it should not be possible to ever have a firmware file that fails this check. If larger version numbers are required in the future, that would be a backwards breaking spec change and thus require a major version bump, in which case an old i915 driver would not load that new version anyway.

2023-05-02i915/pmu: Add support for total context runtime for GuC back-endUmesh Nerlige Ramappa
GPU accumulates the context runtime in a 32 bit counter - CTX_TIMESTAMP in the context image. This value is saved/restored on context switches. KMD accumulates these values into a 64 bit counter taking care of any overflows as needed. This count provides the basis for client specific busyness in the fdinfo interface. KMD accumulation happens just before the context is unpinned and when context switches out. This works for execlist back-end since execlist scheduling has visibility into context switches. With GuC mode, KMD does not have visibility into context switches and this counter is accumulated only when context is unpinned. Context is unpinned once the context scheduling is successfully disabled. Disabling context scheduling is an asynchronous operation. Also if a context is servicing frequent requests, scheduling may never be disabled on it. For GuC mode, since updates to the context runtime may be delayed, add hooks to update the context runtime in a worker thread as well as when a user queries for it. Limitation: - If a context is never switched out or runs for a long period of time, the runtime value of CTX_TIMESTAMP may never be updated, so the counter value may be unreliable. This patch does not support such cases. Such support must be available from the GuC FW and it is WIP.

2023-04-28drm/i915: Use correct huge page manager for MTLJonathan Cavitt
MTL currently uses gen8_ppgtt_insert_huge when managing huge pages. This is because MTL reports as not supporting 64K pages, or more accurately, the system that reports whether a platform has 64K pages reports false for MTL. This is only half correct, as the 64K page support reporting system only cares about 64K page support for LMEM, which MTL doesn't have. MTL should be using xehpsdv_ppgtt_insert_huge. However, simply changing over to using that manager doesn't resolve the issue because MTL is expecting the virtual address space for the page table to be flushed after initialization, so we must also add a flush statement there.

2023-04-28drm/i915/dsi: Use unconditional msleep() instead of intel_dsi_msleep()Hans de Goede
The intel_dsi_msleep() helper skips sleeping if the MIPI-sequences have a version of 3 or newer and the panel is in vid-mode. This is based on the big comment around line 730 which starts with "Panel enable/disable sequences from the VBT spec.", where the "v3 video mode seq" column does not have any wait t# entries. Checking the Windows driver shows that it does always honor the VBT delays independent of the version of the VBT sequences. Commit 6fdb335f1c9c ("drm/i915/dsi: Use unconditional msleep for the panel_on_delay when there is no reset-deassert MIPI-sequence") switched to a direct msleep() instead of intel_dsi_msleep() when there is no MIPI_SEQ_DEASSERT_RESET sequence, to fix the panel on an Acer Aspire Switch 10 E SW3-016 not turning on. And now testing on a Nextbook Ares 8A shows that panel_on_delay must always be honored otherwise the panel will not turn on. Instead of only always using regular msleep() for panel_on_delay do as Windows does and always use regular msleep() everywhere were intel_dsi_msleep() is used and drop the intel_dsi_msleep() helper.

Use `mount -o noswap'. - Qi Zheng has made the slab shrinkers operate locklessly, providing some scalability benefits. - Keith Busch has improved dmapool's performance, making part of its operations O(1) rather than O(n). - Peter Xu adds the UFFD_FEATURE_WP_UNPOPULATED feature to userfaultd, permitting userspace to wr-protect anon memory unpopulated ptes. - Kirill Shutemov has changed MAX_ORDER's meaning to be inclusive rather than exclusive, and has fixed a bunch of errors which were caused by its unintuitive meaning. - Axel Rasmussen give userfaultfd the UFFDIO_CONTINUE_MODE_WP feature, which causes minor faults to install a write-protected pte. - Vlastimil Babka has done some maintenance work on vma_merge(): cleanups to the kernel code and improvements to our userspace test harness. - Cleanups to do_fault_around() by Lorenzo Stoakes. - Mike Rapoport has moved a lot of initialization code out of various mm/ files and into mm/mm_init.c. - Lorenzo Stoakes removd vmf_insert_mixed_prot(), which was added for DRM, but DRM doesn't use it any more. - Lorenzo has also coverted read_kcore() and vread() to use iterators and has thereby removed the use of bounce buffers in some cases. - Lorenzo has also contributed further cleanups of vma_merge(). - Chaitanya Prakash provides some fixes to the mmap selftesting code. - Matthew Wilcox changes xfs and afs so they no longer take sleeping locks in ->map_page(), a step towards RCUification of pagefaults. - Suren Baghdasaryan has improved mmap_lock scalability by switching to per-VMA locking. - Frederic Weisbecker has reworked the percpu cache draining so that it no longer causes latency glitches on cpu isolated workloads. - Mike Rapoport cleans up and corrects the ARCH_FORCE_MAX_ORDER Kconfig logic. - Liu Shixin has changed zswap's initialization so we no longer waste a chunk of memory if zswap is not being used. - Yosry Ahmed has improved the performance of memcg statistics flushing. - David Stevens has fixed several issues involving khugepaged, userfaultfd and shmem. - Christoph Hellwig has provided some cleanup work to zram's IO-related code paths. - David Hildenbrand has fixed up some issues in the selftest code's testing of our pte state changing. - Pankaj Raghav has made page_endio() unneeded and has removed it. - Peter Xu contributed some rationalizations of the userfaultfd selftests. - Yosry Ahmed has fixed an issue around memcg's page recalim accounting. - Chaitanya Prakash has fixed some arm-related issues in the selftests/mm code. - Longlong Xia has improved the way in which KSM handles hwpoisoned pages. - Peter Xu fixes a few issues with uffd-wp at fork() time. - Stefan Roesch has changed KSM so that it may now be used on a per-process and per-cgroup basis. * tag 'mm-stable-2023-04-27-15-30' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (369 commits) mm,unmap: avoid flushing TLB in batch if PTE is inaccessible shmem: restrict noswap option to initial user namespace mm/khugepaged: fix conflicting mods to collapse_file() sparse: remove unnecessary 0 values from rc mm: move 'mmap_min_addr' logic from callers into vm_unmapped_area() hugetlb: pte_alloc_huge() to replace huge pte_alloc_map() maple_tree: fix allocation in mas_sparse_area() mm: do not increment pgfault stats when page fault handler retries zsmalloc: allow only one active pool compaction context selftests/mm: add new selftests for KSM mm: add new KSM process and sysfs knobs mm: add new api to enable ksm per process mm: shrinkers: fix debugfs file permissions mm: don't check VMA write permissions if the PTE/PMD indicates write permissions migrate_pages_batch: fix statistics for longterm pin retry userfaultfd: use helper function range_in_vma() lib/show_mem.c: use for_each_populated_zone() simplify code mm: correct arg in reclaim_pages()/reclaim_clean_pages_from_list() fs/buffer: convert create_page_buffers to folio_create_buffers fs/buffer: add folio_create_empty_buffers helper ...
