7840U amdgpu MMVM_L2_PROTECTION_FAULT_STATUS

by Michael Zimmermann

I have a Framework 13 with a 7840U and started having massive GPU driver issues a few weeks ago (including system freezes). Unfortunately the information of when exactly this started to happen is gone, but It should be somewhere in between 6.6.0 and 6.7.4. I got many different and random dmesg-errors and system behaviors, but I currently can only reproduce one, so let's focus on that for now. First some basic info: I'm on Arch Linux using the `linux` kernel package.(currently at 6.7.4). I have an external monitor connected via a thinkpad thunderbolt 4 dock. I am using amdgpu.sg_display=0 and VRAM sharing is configured to UMA_GAME_OPTIMIZED in the firmware settings. If I start playing a youtube video in firefox with hardware acceleration enabled, it stutters until it stops playing after a few seconds. I can see this in the kernel log. I see this multiple times for many different addresses. [ 5641.070540] amdgpu 0000:c1:00.0: amdgpu: [mmhub] page fault (src_id:0 ring:40 vmid:1 pasid:32786, for process RDD Process pid 3680 thread firefox-bi:cs0 pid 3852) [ 5641.070549] amdgpu 0000:c1:00.0: amdgpu: in page starting at address 0x0000000000020000 from client 18 [ 5641.070553] amdgpu 0000:c1:00.0: amdgpu: MMVM_L2_PROTECTION_FAULT_STATUS:0x00143A51 [ 5641.070556] amdgpu 0000:c1:00.0: amdgpu: Faulty UTCL2 client ID: unknown (0x1d) [ 5641.070559] amdgpu 0000:c1:00.0: amdgpu: MORE_FAULTS: 0x1 [ 5641.070561] amdgpu 0000:c1:00.0: amdgpu: WALKER_ERROR: 0x0 [ 5641.070563] amdgpu 0000:c1:00.0: amdgpu: PERMISSION_FAULTS: 0x5 [ 5641.070565] amdgpu 0000:c1:00.0: amdgpu: MAPPING_ERROR: 0x0 [ 5641.070567] amdgpu 0000:c1:00.0: amdgpu: RW: 0x1 Thanks Michael

[PATCH 2/6] drm/buddy: fix range bias

by Matthew Auld

There is a corner case here where start/end is after/before the block range we are currently checking. If so we need to be sure that splitting the block will eventually give use the block size we need. To do that we should adjust the block range to account for the start/end, and only continue with the split if the size/alignment will fit the requested size. Not doing so can result in leaving split blocks unmerged when it eventually fails.

[PATCH 5.10.y] bpf: Convert BPF_DISPATCHER to use static_call() (not ftrace)

by kovalev＠altlinux.org

From: Peter Zijlstra <peterz(a)infradead.org> [ Upstream commit c86df29d11dfba27c0a1f5039cd6fe387fbf4239 ] The dispatcher function is currently abusing the ftrace __fentry__ call location for its own purposes -- this obviously gives trouble when the dispatcher and ftrace are both in use. A previous solution tried using __attribute__((patchable_function_entry())) which works, except it is GCC-8+ only, breaking the build on the earlier still supported compilers. Instead use static_call() -- which has its own annotations and does not conflict with ftrace -- to rewrite the dispatch function. By using: return static_call()(ctx, insni, bpf_func) you get a perfect forwarding tail call as function body (iow a single jmp instruction). By having the default static_call() target be bpf_dispatcher_nop_func() it retains the default behaviour (an indirect call to the argument function). Only once a dispatcher program is attached is the target rewritten to directly call the JIT'ed image.

[PATCH 5.15.y] bpf: Convert BPF_DISPATCHER to use static_call() (not ftrace)

by kovalev＠altlinux.org

From: Peter Zijlstra <peterz(a)infradead.org> [ Upstream commit c86df29d11dfba27c0a1f5039cd6fe387fbf4239 ] The dispatcher function is currently abusing the ftrace __fentry__ call location for its own purposes -- this obviously gives trouble when the dispatcher and ftrace are both in use. A previous solution tried using __attribute__((patchable_function_entry())) which works, except it is GCC-8+ only, breaking the build on the earlier still supported compilers. Instead use static_call() -- which has its own annotations and does not conflict with ftrace -- to rewrite the dispatch function. By using: return static_call()(ctx, insni, bpf_func) you get a perfect forwarding tail call as function body (iow a single jmp instruction). By having the default static_call() target be bpf_dispatcher_nop_func() it retains the default behaviour (an indirect call to the argument function). Only once a dispatcher program is attached is the target rewritten to directly call the JIT'ed image.

[PATCH v2] arm64: Subscribe Microsoft Azure Cobalt 100 to ARM Neoverse N2 errata

by Easwar Hariharan

Add the MIDR value of Microsoft Azure Cobalt 100, which is a Microsoft implemented CPU based on r0p0 of the ARM Neoverse N2 CPU, and therefore suffers from all the same errata.
