drm/amdgpu: Fix the memory allocation issue in amdgpu_discovery_get_nps_info()

2024-12-05T13:01:52Z

[ Upstream commit a1144da794adedb9447437c57d69add56494309d ] Fix two issues with memory allocation in amdgpu_discovery_get_nps_info() for mem_ranges: - Add a check for allocation failure to avoid dereferencing a null pointer. - As suggested by Christophe, use kvcalloc() for memory allocation, which checks for multiplication overflow. Additionally, assign the output parameters nps_type and range_cnt after the kvcalloc() call to prevent modifying the output parameters in case of an error return.

drm/amdgpu: fix eGPU hotplug regression

2024-08-21T03:07:11Z

The driver needs to wait for the on board firmware to finish its initialization before probing the card. Commit 959056982a9b ("drm/amdgpu: Fix discovery initialization failure during pci rescan") switched from using msleep() to using usleep_range() which seems to have caused init failures on some navi1x boards. Switch back to msleep().
