2019-10-25drm/i915: split gen11_irq_handler to make it shareableLucas De Marchi1-5/+14
Split gen11_irq_handler() to receive as parameter the function pointers. This allows to share the interrupt handler even if the enable/disable functions are different. Make sure it's always inlined to avoid the extra indirect call on the hot path. Checking with gcc 9 this produce the exact same code as of now: $ size drivers/gpu/drm/i915/i915_irq*.o text data bss dec hex filename 47511 560 0 48071 bbc7 drivers/gpu/drm/i915/i915_irq.o 47511 560 0 48071 bbc7 drivers/gpu/drm/i915/i915_irq_new.o $ gdb -batch -ex 'file drivers/gpu/drm/i915/i915_irq.o' -ex 'disassemble gen11_irq_handler' > /tmp/old.s $ gdb -batch -ex 'file drivers/gpu/drm/i915/i915_irq_new.o' -ex 'disassemble gen11_irq_handler' > /tmp/new.s $ git diff --no-index /tmp/{old,new}.s $ So, no change in behavior, just a simple refactor.

2019-10-25drm/amdkfd: don't use dqm lock during device reset/suspend/resumePhilip Yang3-10/+43
If device reset/suspend/resume failed for some reason, dqm lock is hold forever and this causes deadlock. Below is a kernel backtrace when application open kfd after suspend/resume failed. Instead of holding dqm lock in pre_reset and releasing dqm lock in post_reset, add dqm->sched_running flag which is modified in dqm->ops.start and dqm->ops.stop. The flag doesn't need lock protection because write/read are all inside dqm lock.
