Now that the highest_bank_bit value is retrieved from the running
system and the global config has been part of the tree for a couple
of releases, there is no reason to keep any hardcoded values inside
the GPU driver.
Get rid of them.

The UBWC registers in the MDSS region are not dependent on the UBWC
version (it is an invalid assumption we inherited from the vendor SDE
driver). Instead they are dependent only on the MDSS core revision.
Rework UBWC programming to follow MDSS revision and to use required (aka
encoder) UBWC version instead of the ubwc_dec_version.

The snapshotting code internally aligns data segment to 16 bytes. This
works fine for DPU code (where most of the regions are aligned), but
fails for snapshotting of the DSI data (because DSI data region is
shifted by 4 bytes). Fix the code by removing length alignment and by
accurately printing last registers in the region. While reworking the
code also fix the 16x memory overallocation in

UTS_RELEASE evaluates to a static string and changes quite easily (e.g.
uncommitted changes in the source tree or new commits). So when checking
if a patch introduces changes to the resulting binary each usage of
UTS_RELEASE is source of annoyance.
Instead of using UTS_RELEASE directly use init_utsname()->release which
evaluates to the same string but with that a change of UTS_RELEASE
doesn't affect msm_disp_snapshot_util.o or msm_gpu.o.

On DSI 6G platforms the IO address space is internally adjusted by
io_offset. Later this adjusted address might be used for memory dumping.
However the size that is used for memory dumping isn't adjusted to
account for the io_offset, leading to the potential access to the
unmapped region. Lower ctrl_size by the io_offset value to prevent
access past the mapped area.

CWB base addresses for this platform (0x169200, 0x169600, 0x16a200,
0x16a600), but the dpu_kaanapali_cfg struct was mistakenly pointing
to sm8650_cwb instead. The SM8650 CWB blocks sit at completely
different offsets (0x66200, 0x66600, 0x7E200, 0x7E600), so using
them on Kaanapali would program CWB registers at wrong addresses,
corrupting unrelated hardware blocks and breaking writeback capture.

Initial SoC Slider support
SoC Slider is an SoC-wide power/performance policy setting.
On SoC Slider systems, EPP plays a diminished role.
Whitespace cleanup via: indent -npro -kr -i8 -ts8 -sob -l160 -ss -ncs -cp1
No functional changes
Signed-off-by: Len Brown <len.brown@intel.com>
x86_energy_perf_policy accesses the SoC Slider via standard
user/kernel APIs to the processor_thermal_soc_slider driver.
Machines that support SoC Slider largely use it instead of EPP,
which may continue to exist in a diminished role, or vanish entirely.
Signed-off-by: Len Brown <len.brown@intel.com>
When processor_thermal_soc_slider is loaded, its slider
and offset modparams are visible. Check that the driver
actually registered the profile named "SoC Slider" before
reading or writing these modparams.
n.b. This utility allows writing the Slider and Offset modparams
even if the driver policy is not "balanced". Currently the
processor_thermal_soc_slider consults those modparams
only in "balanced" mode.

On Raspberry Pi 3B, the VEC clock is used by the VideoCore firmware
display driver, which remains active until the vc4 driver loads and
sends NOTIFY_DISPLAY_DONE. If this clock is disabled during boot, a bus
lockup happens and the firmware becomes unresponsive, causing a complete
system lockup.
Mark the VEC clock with CLK_IGNORE_UNUSED so it survives the unused
clock disablement and remains available until the vc4 driver takes over
display management.

- Fix accounting of persistent ring buffer rewind
On boot up, the head page is moved back to the earliest point of
the saved ring buffer. This is because the ring buffer being read by
user space on a crash may not save the part it read. Rewinding the head
page back to the earliest saved position helps keep those events from
being lost.
The number of events is also read during boot up and displayed in the
stats file in the tracefs directory. It's also used for other accounting
as well. On boot up, the "reader page" is accounted for but a rewind may
put it back into the buffer and then the reader page may be accounted
for again.
Save off the original reader page and skip accounting it when scanning
the pages in the ring buffer.
