drm/amd/amdgpu: Fix GPR read from debugfs (v2)

2020-03-25T07:25:56+00:00

commit 5bbc6604a62814511c32f2e39bc9ffb2c1b92cbe upstream. The offset into the array was specified in bytes but should be in terms of 32-bit words. Also prevent large reads that would also cause a buffer overread. v2: Read from correct offset from internal storage buffer.

drm/amdgpu: Avoid accidental thread reactivation.

[ Upstream commit a28fda312a9fabdf0e5f5652449d6197c9fb0a90 ] Problem: During GPU reset we call the GPU scheduler to suspend it's thread, those two functions in amdgpu also suspend and resume the sceduler for their needs but this can collide with GPU reset in progress and accidently restart a suspended thread before time. Fix: Serialize with GPU reset. Signed-off-by: Andrey Grodzovsky Reviewed-by: Christian König Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amdgpu: fix a potential information leaking bug

2019-07-31T06:26:09+00:00

Coccinelle reports a path that the array "data" is never initialized. The path skips the checks in the conditional branches when either of callback functions, read_wave_vgprs and read_wave_sgprs, is not registered. Later, the uninitialized "data" array is read in the while-loop below and passed to put_user(). Fix the path by allocating the array with kcalloc(). The patch is simplier than adding a fall-back branch that explicitly calls memset(data, 0, ...). Also it does not need the multiplication 1024*sizeof(*data) as the size parameter for memset() though there is no risk of integer overflow.
