Currently, gcc spews a warning as: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_hubbub.c: In function ‘hubbub1_verify_allow_pstate_change_high’: ./include/drm/drm_print.h:316:2: warning: ‘debug_data’ may be used uninitialized in this function [-Wmaybe-uninitialized] This is because the code checks against a static value although it's basically a constant and guaranteed to be set. This patch changes the type prefix from static to const for addressing the compile warning above and also for letting the compiler optimize better. Fixes: 62d591a8 ("drm/amd/display: create new files for hubbub functions") Reviewed-by:

Provide compute queues information in sysfs under /sys/class/kfd/kfd/proc. The format is /sys/class/kfd/kfd/proc/<pid>/queues/<queue id>/XX where XX are size, type, and gpuid three files to represent queue size, queue type, and the GPU this queue uses. <queue id> folder and files underneath are generated when a queue is created. They are removed when the queue is destroyed. Signed-off-by:

[Why] Starting from 14nm, the PLL is built into the PHY and the PLL is mapped to PHY on 1 to 1 basis. In the code, the DP port is mapped to a PLL that was not initialized. This causes DP to HDMI dongle to not light up the display. [How] Initializations added for PLL2 when creating resources. Signed-off-by:

[Why] these registers should have been double buffered. SW workaround we will have SW program the more aggressive (lower) values whenever we are upating this register, so we will not have underflow at expense of less optimzal request pattern. [How] there is a driver bug where we don't check for 0, which is uninitialzed HW default. since 0 is smaller than any value we need to program, driver end up with not programming these registers Signed-off-by:

[Why] The DMCUB may be currently executing commands when the reset is triggered. Before issuing a reset we should first wait for the DMCUB to finish its work. [How] Send the GPINT command for halting the firmware before reset. Get the ack for the command then wait for the scratch register to become the correct value. We want this to take under ~40us or so at most before we force reset to cover PHY delay sequence max time. Each register read will be at least ~1-3us so don't bother using udelay. Signed-off-by:

For sriov, psp ip block has to be initialized before ih block for the dynamic register programming interface that needed for vf ih ring buffer. On the other hand, current psp ip block hw_init function will initialize xgmi session which actaully depends on interrupt to return session context. This results an empty xgmi ta session id and later failures on all the xgmi ta cmd invoked from vf. xgmi ta session initialization has to be done after ih ip block hw_init call. to unify xgmi session init/fini for both bare-metal sriov virtualization use scenario, move xgmi ta init to xgmi_add_device call, and accordingly terminate xgmi ta session in xgmi_remove_device call.

[Why] PSP doesn't have the ability to store SRM in a non-volatile memory. And since the kernel cannot write to the storage directly, we need usermode to facilitate this As per spec the SRM needs to be persistent so this interface is to be called by the usermode anytime the system goes down/powers on *boot/resume: load from storage *shutdown/suspend: save to storage [How] Provide a sysfs interface so that the usermode can set/get srm at the right times save to storage: call "cat /sys/class/drm/card0/device/hdcp_srm > file" after boot and resume -driver calls psp_get_srm() to get the stored srm and outputs it load from storage: call "cat file > /sys/class/drm/card0/device/hdcp_srm" before shutdown and suspend -driver reads the file from sysfs and calls psp_set_srm() to send the SRM to PSP v2: -update commit description -add comment about sysfs file handling in the code v3: - squash in use after free fix (Dan Carpenter) Signed-off-by:
