On dGPUs user mode virtual addresses are managed by the Thunk's GPU memory allocation code. Therefore we can't allocate the memory in kernel mode like we do on APUs. But KFD still needs to map the memory for kernel access. To facilitate this, the Thunk provides the buffer handle of the events page to KFD when creating the first event.

This limitation is not necessary. Scratch and LDS represent per-work-item and per-work-group storage respectively. Different work-items and work-groups use the same virtual address to access their own data. Work running on different GPUs is by definition in different work-groups (different dispatches, in fact). That means the same virtual addresses can be used for these apertures on different GPUs. Add a new AMDKFD_IOC_GET_PROCESS_APERTURES_NEW ioctl that removes the artificial limitation on the number of GPUs that can be supported. The new ioctl allows user mode to query the number of GPUs to allocate enough memory for all GPUs to be reported. This deprecates AMDKFD_IOC_GET_PROCESS_APERTURES.

This was caused by not considering if we resumed from hibernation as the condition for power domains reiniting. Fix this by simply tracking if we suspended power domains during system suspend and reinit power domains accordingly during resume. This will result in reiniting power domains always when resuming from hibernation, regardless of the platform and whether or not i915 is loaded by the loader kernel. The reason we didn't catch this earlier is that the enabled/disabled state of power domains during PMSG_FREEZE/PMSG_QUIESCE is platform and kernel config dependent: on my SKL the target state is S4 during PMSG_FREEZE and (with the driver loaded in the loader kernel) S0 during PMSG_QUIESCE. On the reporter's machine it's S0 during PMSG_FREEZE but (contrary to this) power domains are not initialized during PMSG_QUIESCE since i915 is not loaded in the loader kernel, or it's loaded but without the DMC firmware being available.

However, in commit 767a983ab255 ("drm/i915/execlists: Read the context-status HEAD from the HWSP") those uncached reads were eliminated (on one path at least) and along with them our serialisation. The result is that we would very rarely miss notification of a new interrupt and leave a context-switch unprocessed, hanging the GPU.

Consequently, we write to the DP_SET_POWER dpcd to set it D3 state. Further along when we try enable the encoder in MST mode, POWER_UP_PHY transaction fails to power up the MST hub. This results in continuous link training failures which keep the system busy delaying boot. We could identify bios MST boot discrepancy and handle it accordingly but a simple way to solve this is to write to the DP_SET_POWER dpcd for MST too.
