treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12Z

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

drm/amdgpu: use GFP_NOWAIT for memory allocations

2025-03-21T16:15:08Z

In the critical submission path memory allocations can't wait for reclaim since that can potentially wait for submissions to finish. Finally clean that up and mark most memory allocations in the critical path with GFP_NOWAIT. The only exception left is the dma_fence_array() used when no VMID is available, but that will be cleaned up later on.

drm/amd: Add the capability to mark certain firmware as "required"

2024-12-10T15:26:51Z

Some of the firmware that is loaded by amdgpu is not actually required. For example the ISP firmware on some SoCs is optional, and if it's not present the ISP IP block just won't be initialized. The firmware loader core however will show a warning when this happens like this: ``` Direct firmware load for amdgpu/isp_4_1_0.bin failed with error -2 ``` To avoid confusion for non-required firmware, adjust the amd-ucode helper to take an extra argument indicating if the firmware is required or optional. On optional firmware use firmware_request_nowarn() instead of request_firmware() to avoid the warnings.
