2024-11-13drm/xe: handle flat ccs during hibernation on igpuMatthew Auld1-1/+12
Starting from LNL, CCS has moved over to flat CCS model where there is now dedicated memory reserved for storing compression state. On platforms like LNL this reserved memory lives inside graphics stolen memory, which is not treated like normal RAM and is therefore skipped by the core kernel when creating the hibernation image. Currently if something was compressed and we enter hibernation all the corresponding CCS state is lost on such HW, resulting in corrupted memory. To fix this evict user buffers from TT -> SYSTEM to ensure we take a snapshot of the raw CCS state when entering hibernation, where upon resuming we can restore the raw CCS state back when next validating the buffer. This has been confirmed to fix display corruption on LNL when coming back from hibernation.

2024-11-13drm/xe: improve hibernation on igpuMatthew Auld2-27/+16
The GGTT looks to be stored inside stolen memory on igpu which is not treated as normal RAM. The core kernel skips this memory range when creating the hibernation image, therefore when coming back from hibernation the GGTT programming is lost. This seems to cause issues with broken resume where GuC FW fails to load: [drm] *ERROR* GT0: load failed: status = 0x400000A0, time = 10ms, freq = 1250MHz (req 1300MHz), done = -1 [drm] *ERROR* GT0: load failed: status: Reset = 0, BootROM = 0x50, UKernel = 0x00, MIA = 0x00, Auth = 0x01 [drm] *ERROR* GT0: firmware signature verification failed [drm] *ERROR* CRITICAL: Xe has declared device 0000:00:02.0 as wedged. Current GGTT users are kernel internal and tracked as pinned, so it should be possible to hook into the existing save/restore logic that we use for dgpu, where the actual evict is skipped but on restore we importantly restore the GGTT programming. This has been confirmed to fix hibernation on at least ADL and MTL, though likely all igpu platforms are affected. This also means we have a hole in our testing, where the existing s4 tests only really test the driver hooks, and don't go as far as actually rebooting and restoring from the hibernation image and in turn powering down RAM (and therefore losing the contents of stolen). v2 (Brost) - Remove extra newline and drop unnecessary parentheses.

2024-11-07drm/panthor: Be stricter about IO mapping flagsJann Horn1-0/+4
The current panthor_device_mmap_io() implementation has two issues: 1. For mapping DRM_PANTHOR_USER_FLUSH_ID_MMIO_OFFSET, panthor_device_mmap_io() bails if VM_WRITE is set, but does not clear VM_MAYWRITE. That means userspace can use mprotect() to make the mapping writable later on. This is a classic Linux driver gotcha. I don't think this actually has any impact in practice: When the GPU is powered, writes to the FLUSH_ID seem to be ignored; and when the GPU is not powered, the dummy_latest_flush page provided by the driver is deliberately designed to not do any flushes, so the only thing writing to the dummy_latest_flush could achieve would be to make *more* flushes happen. 2. panthor_device_mmap_io() does not block MAP_PRIVATE mappings (which are mappings without the VM_SHARED flag). MAP_PRIVATE in combination with VM_MAYWRITE indicates that the VMA has copy-on-write semantics, which for VM_PFNMAP are semi-supported but fairly cursed. In particular, in such a mapping, the driver can only install PTEs during mmap() by calling remap_pfn_range() (because remap_pfn_range() wants to **store the physical address of the mapped physical memory into the vm_pgoff of the VMA**); installing PTEs later on with a fault handler (as panthor does) is not supported in private mappings, and so if you try to fault in such a mapping, vmf_insert_pfn_prot() splats when it hits a BUG() check. Fix it by clearing the VM_MAYWRITE flag (userspace writing to the FLUSH_ID doesn't make sense) and requiring VM_SHARED (copy-on-write semantics for the FLUSH_ID don't make sense). Reproducers for both scenarios are in the notes of my patch on the mailing list; I tested that these bugs exist on a Rock 5B machine. Note that I only compile-tested the patch, I haven't tested it; I don't have a working kernel build setup for the test machine yet. Please test it before applying it.

2024-11-05drm/xe: Stop accumulating LRC timestamp on job_freeLucas De Marchi2-2/+6
The exec queue timestamp is only really useful when it's being queried through the fdinfo. There's no need to update it so often, on every job_free. Tracing a simple app like vkcube running shows an update rate of ~ 120Hz. In case of discrete, the BO is on vram, creating a lot of pcie transactions. The update on job_free() is used to cover a gap: if exec queue is created and destroyed rapidly, before a new query, the timestamp still needs to be accumulated and accounted for in the xef. Initial implementation in commit 6109f24f87d7 ("drm/xe: Add helper to accumulate exec queue runtime") couldn't do it on the exec_queue_fini since the xef could be gone at that point. However since commit ce8c161cbad4 ("drm/xe: Add ref counting for xe_file") the xef is refcounted and the exec queue always holds a reference, making this safe now. Improve the fix in commit 2149ded63079 ("drm/xe: Fix use after free when client stats are captured") by reducing the frequency in which the update is needed.
