2024-05-08drm/amdkfd: Check debug trap enable before write dbg_ev_fileLin.Cao
In interrupt context, write dbg_ev_file will be run by work queue. It will cause write dbg_ev_file execution after debug_trap_disable, which will cause NULL pointer access. v2: cancel work "debug_event_workarea" before set dbg_ev_file as NULL.

2024-05-08drm/amdkfd: Let VRAM allocations go to GTT domain on small APUsLang Yu
Small APUs(i.e., consumer, embedded products) usually have a small carveout device memory which can't satisfy most compute workloads memory allocation requirements. We can't even run a Basic MNIST Example with a default 512MB carveout. https://github.com/pytorch/examples/tree/main/mnist. Error Log: "torch.cuda.OutOfMemoryError: HIP out of memory. Tried to allocate 84.00 MiB. GPU 0 has a total capacity of 512.00 MiB of which 0 bytes is free. Of the allocated memory 103.83 MiB is allocated by PyTorch, and 22.17 MiB is reserved by PyTorch but unallocated" Though we can change BIOS settings to enlarge carveout size, which is inflexible and may bring complaint. On the other hand, the memory resource can't be effectively used between host and device. The solution is MI300A approach, i.e., let VRAM allocations go to GTT. Then device and host can flexibly and effectively share memory resource. v2: Report local_mem_size_private as 0.

However the spec says: "This block is obsolete and should not be consumed for any compression programming." Block 56 is the replacement that should actually be used. So let's just name the obsolete old block but not even bother defining the contents.

2024-05-08drm/i915/bios: Define VBT block 50 (MIPI) contentsVille Syrjälä
Define the contents of VBT block 50 (MIPI). This was some easly attempt at a MIPI DSI stuff. I'm not sure this was ever actually used (I certainly don't have any VBTs with this block), but here's some kind of definition for it anyway.

2024-05-08drm/i915/bios: Define VBT block 57 (Vswing PreEmphasis Table) contentsVille Syrjälä
Define the contents of VBT block 57 (Vswing PreEmphasis Table). The contents is highly platform specific. The columns of the table corresponding to some set of PHY/etc registers. The rows corresponding to all legal vswing+pre-emphasis combinations (ie. should be 10 rows in each table). And each table corresponds to a platform specific (mostly undocumented) mapping based on link rate/eDP low-vswing/etc. parameters.

2024-05-08drm/drm-bridge: Drop conditionals around of_node pointersSui Jingfeng
Having conditional around the of_node pointer of the drm_bridge structure is not necessary, since drm_bridge structure always has the of_node as its member. Let's drop the conditional to get a better looks, please also note that this is following the already accepted commitments. see commit d8dfccde2709 ("drm/bridge: Drop conditionals around of_node pointers") for reference.
