hwc->conf was designated specifically for AMD APU IOMMU purposes. This could cause problems in performance and/or function since APU IOMMU implementation is elsewhere. Also hwc->conf and hwc->config are different members of an anonymous union so hwc->conf aliases as hw->last_tag. Signed-off-by:

On PowerPC, the compiler will tag object files with whether they use hard or soft float FP ABI and whether they use 64 or 128-bit long double ABI. On systems with 64-bit long double ABI, a tag will get emitted whenever a double is used, as on those systems a long double is the same as a double. This will prevent linkage as other files are being compiled with hard-float. On ppc64, this code will never actually get used for the time being, as the only currently existing hardware using it are the Renoir APUs. Therefore, until this is testable and can be fixed properly, at least make sure the build will not fail. Signed-off-by:

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.

[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:
