Here, If ioremap_nocache will fail. It will return NULL. Kernel can run into a NULL-pointer dereference. This error check will avoid NULL pointer dereference. Signed-off-by:

In the case of pass-through, amdgpu.ko may be included into a image with the hard code ID therefore loading driver with specified virtual display ID will lose efficacy when the BDF of GPU modifies.So add the new ID string "all" for it as same as vf case what does. Reviewed-by:

Keeping groups of BOs on the LRU is to time consuming on command submission. Instead use the newly added BO priority to give a certain eviction order. v2: agd: trivial warning fix Signed-off-by:
-
Christian König authored
This way the driver can specify a priority for a BO which has the effect that a BO is only evicted when all other BOs with a lower priority are evicted first. Reviewed-by:

The scratch regs are sequential so there's no need to keep them in an array, we can just return the index of the first free register + the base register. Also change the array of bools for keeping track of the free regs to a bitfield. Reviewed-by:

ttm_bo_init checks that the reservation object is locked. This is the caller's responsibility when resv != NULL. Otherwise, the inline reservation object of the newly allocated buffer is used and must explicitly be locked.
