linux.git/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c, branch v6.8-rc2 Linux kernel source tree drm/amdgpu: revert "Adjust removal control flow for smu v13_0_2" 2024-01-18T21:43:42+00:00 Christian König christian.koenig@amd.com 2024-01-10T14:19:29+00:00 fb1c93c2e9604a884467a773790016199f78ca08 Calling amdgpu_device_ip_resume_phase1() during shutdown leaves the HW in an active state and is an unbalanced use of the IP callbacks. Using the IP callbacks like this can lead to memory leaks, double free and imbalanced reference counters. Leaving the HW in an active state can lead to DMA accesses to memory now freed by the driver. Both is a complete no-go for driver unload so completely revert the workaround for now. This reverts commit f5c7e7797060255dbc8160734ccc5ad6183c5e04.

Calling amdgpu_device_ip_resume_phase1() during shutdown leaves the
HW in an active state and is an unbalanced use of the IP callbacks.

Using the IP callbacks like this can lead to memory leaks, double
free and imbalanced reference counters.

Leaving the HW in an active state can lead to DMA accesses to memory now
freed by the driver.

Both is a complete no-go for driver unload so completely revert the
workaround for now.

This reverts commit f5c7e7797060255dbc8160734ccc5ad6183c5e04.
