Why:
If the reg mmMP1_SMN_C2PMSG_90 is being written to during amdgpu driver
load or driver unload, subsequent amdgpu driver load will fail at
smu_hw_init. The default of mmMP1_SMN_C2PMSG_90 register at a clean
environment is 0x1 and if value differs from expected, amdgpu driver
load will fail.
How to fix:
Ignore the initial value in smu response register before the first smu
message is sent,if smc in SMU_FW_INIT state, just proceed further to
send the message. If register holds an unexpected value after smu message
was sent set, smc_state to SMU_FW_HANG state and no further smu messages
will be sent.
v2:
Set SMU_FW_INIT state at the start of smu hw_init/resume.
Check smc_fw_state before sending smu message if in hang state skip
sending message.
Set SMU_FW_HANG only in case unexpected value is detected

If a queue is already assigned to the hardware, then a newly submitted
job can start straight away without waiting for the tick. However in
this case the devfreq infrastructure isn't notified that the GPU is
busy. By the time the tick happens the job might well have finished and
no time will be accounted for the GPU being busy.
Fix this by recording the GPU as busy directly in queue_run_job() in the
case where there is a CSG assigned and therefore we just ring the
doorbell.

Add helpers to convert between q4 fixed point and integer/fraction
values. Also add the format/argument macros required to printk q4 fixed
point variables. The q4 notation is based on the short variant described
by
https://en.wikipedia.org/wiki/Q_(number_format)
where only the number of fraction bits in the fixed point value are
defined, while the full size is deducted from the container type, that
is the size of int for these helpers. Using the fxp_ prefix, which makes
moving these helpers outside of drm to a more generic place easier, if
they prove to be useful.
These are needed by later patches dumping the Display Stream Compression
configuration in DRM core and in the i915 driver to replace the
corresponding bpp_x16 helpers defined locally in the driver.
v2: Use the more generic/descriptive fxp_q4 prefix instead of drm_x16.

Panfrost DRM driver uses devfreq to perform DVFS, while using simple_ondemand
devfreq governor by default. This causes driver initialization to fail on
boot when simple_ondemand governor isn't built into the kernel statically,
as a result of the missing module dependency and, consequently, the required
governor module not being included in the initial ramdisk. Thus, let's mark
simple_ondemand governor as a softdep for Panfrost, to have its kernel module
included in the initial ramdisk.
This is a rather longstanding issue that has forced distributions to build
devfreq governors statically into their kernels, [1][2] or has forced users
to introduce some unnecessary workarounds. [3]
For future reference, not having support for the simple_ondemand governor in
the initial ramdisk produces errors in the kernel log similar to these below,
which were taken from a Pine64 RockPro64:
panfrost ff9a0000.gpu: [drm:panfrost_devfreq_init [panfrost]] *ERROR* Couldn't initialize GPU devfreq
panfrost ff9a0000.gpu: Fatal error during GPU init
panfrost: probe of ff9a0000.gpu failed with error -22
Having simple_ondemand marked as a softdep for Panfrost may not resolve this
issue for all Linux distributions. In particular, it will remain unresolved
for the distributions whose utilities for the initial ramdisk generation do
not handle the available softdep information [4] properly yet. However, some
Linux distributions already handle softdeps properly while generating their
initial ramdisks, [5] and this is a prerequisite step in the right direction
for the distributions that don't handle them properly yet.
