drm/amdgpu: disable gfxoff when using register read interface

2019-11-20T23:40:21Z

When gfxoff is enabled, accessing gfx registers via MMIO can lead to a hang. Bug: https://bugzilla.kernel.org/show_bug.cgi?id=205497 Acked-by: Xiaojie Yuan Reviewed-by: Evan Quan Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amdgpu: Bail earlier when amdgpu.cik_/si_support is not set to 1

2019-10-12T02:31:14Z

Bail from the pci_driver probe function instead of from the drm_driver load function. This avoid /dev/dri/card0 temporarily getting registered and then unregistered again, sending unwanted add / remove udev events to userspace. Specifically this avoids triggering the (userspace) bug fixed by this plymouth merge-request: https://gitlab.freedesktop.org/plymouth/plymouth/merge_requests/59 Note that despite that being a userspace bug, not sending unnecessary udev events is a good idea in general.

drm/amdgpu: Check for valid number of registers to read

2019-09-17T19:37:45Z

Do not try to allocate any amount of memory requested by the user. Instead limit it to 128 registers. Actually the longest series of consecutive allowed registers are 48, mmGB_TILE_MODE0-31 and mmGB_MACROTILE_MODE0-15 (0x2644-0x2673).
