PIPEGCMAX is a 11.6 (or 1.16 if you will) value. Ie. it can
represent a value of 1.0 when the maximum we can store in the
software LUT is 0.ffff. Clamp the value so that it gets
saturated to the max the uapi supports.

Extract all the 'hw value -> LUT entry' stuff into small helpers
to make the main 'read out the entire LUT' loop less bogged down
by such mundane details.

A variable called 'i' having an unsigned type is just looking for
trouble, and using a sized type generally makes no sense either.
Change all of them to just plain old int. And do the same for some
'lut_size' variables which generally provide the loop end codition
for 'i'.

chv_read_cgm_lut() specifically reads the CGM _gamma_ LUT so
let's rename it to reflect that fact. This also mirrors
the other direction's chv_load_cgm_gamma().

We're talking about LUT contents here so let's call the thing
'lut' rather than 'blob_data'. This is the name the load_lut()
code used before already.

To mirror the load_luts path let's clone an ilk+ version
from i9xx_read_lut_8(). I guess the extra branch isn't a huge
issue but feels better to make a clean split.

Before rebooting the box, a "ssh sync" is called to the test machine to see
if it is alive or not. But if the test machine is in a partial state, that
ssh may never actually finish, and the ktest test hangs.
Add a 10 second timeout to the sync test, which will fail after 10 seconds
and then cause the test to reboot the test machine.

For the last time, I screwed up my ktest config file, and the build went
into the default "randconfig", blowing away the .config that I had set up.
The reason for the default randconfig was because when this was first
written, I wanted to do a bunch of randconfigs. But as time progressed,
ktest isn't about randconfig anymore, and because randconfig destroys the
config in the build directory, it's a dangerous default to have. Use
oldconfig as the default.

Only load the CGM CSC based on the cgm_mode bit like we
do with the gamma/degamma LUTs. And make the function
naming and arguments consistent as well.
TODO: the code to convert the coefficients look totally
bogus. IIRC CHV uses two's complement format but the code
certainly doesn't generate that, so probably negative
coefficients are totally busted.

Problem Description:
Currently we are checking internal fused rev id with pci rev id. However, fused
internal rev id is the same on all raven2 parts (in which Dali and Pollock were
based on too), thus Pollock detection fails
Fix:
use the pci rev to preform the detection for bandwidth calculations.

Raven provides retimer feature support that requires i2c interaction in
order to make it work well, all settings required for this configuration
are loaded from the Atom bios which include the i2c address. If the
retimer feature is not available, we should abort the attempt to set
this feature, otherwise, it makes the following line return
I2C_CHANNEL_OPERATION_NO_RESPONSE:
i2c_success = i2c_write(pipe_ctx, slave_address, buffer, sizeof(buffer));
...
if (!i2c_success)
ASSERT(i2c_success);
This ends up causing problems with hotplugging HDMI displays on Raven,
and causes retimer settings to warn like so:

This commit reworks the way that we handle i2c write for retimer in the
way that we abort this configuration if the feature is not available in
the device. For debug sake, we kept a simple log message in case the
retimer is not available.

Some RX doesn't like us to read rx id list upto max rx id list size. As
discussed, we decided to read rx id list based on device count.
[how]
According to HDCP specs the actual size of rx id list is calculated as
rx id list size = 2+3+16+5*device_count. We will read 16 bytes at a
time until it reached or exceeded rx id list size.

[why]
Link or DIG BE can't be exposed to a higher stream bandwidth than they
can handle. When DSC is required to fit the stream into the link
bandwidth, DSC has to be programmed during timing programming to ensure
this. Without it, intermittent issues such as black screen after S3 or a
hot-plug can be seen.
[how]
Move DSC programming from enabling stream on link to timing setup.

System isn't able to enter S0i3 due to not send display count 0 to smu.
When dpms off, clk changed flag is cleared alreay, and it is checked
when doing optimized bandwidth, and update clocks is bypassed due to the
flag is unset.
[How]
Remove check flag incide the function since watermark values and clocks
values are checked during update to determine whether to perform it, no
need to check it again outside the function.

Commit a758f50f10cf ("mtd: onenand: omap2: Configure driver from DT")
started using DT specified timings for GPMC, and as a result the
OneNAND stopped working on N900 as we had wrong values in the DT.
Fix by updating the values to bootloader timings that have been tested
to be working on Nokia N900 with OneNAND manufacturers: Samsung,
Numonyx.

Commit adb72394e2ab ("ARM: OMAP2+: Drop legacy platform data for am3
lcdc") dropped legacy platform data but we never added the quirks for
SWSUP_SIDLE and SWSUP_MSTANDBY for lcdc for ti-sysc driver.
This breaks suspend/resume. Let's fix the issue by enabling the same
quirks for ti-sysc driver as we had earlier with platform data.

The UNSLICE_UNIT_LEVEL_CLKGATE and UNSLICE_UNIT_LEVEL_CLKGATE2 registers
that we update in a few engine workarounds are not masked registers
(i.e., we don't have to write a mask bit in the top 16 bits when
updating one of the lower 16 bits). As such, these workarounds should
be applied via wa_write_or() rather than wa_masked_en()

The hierarchical parts of MSM pinctrl/GPIO is only
used when the device tree has a "wakeup-parent" as
a phandle, but the .irq_eoi is anyway assigned leading
to semantic problems on elder Qualcomm chipsets.
When the drivers/mfd/qcom-pm8xxx.c driver calls
chained_irq_exit() that call will in turn call chip->irq_eoi()
which is set to irq_chip_eoi_parent() by default on a
hierachical IRQ chip, and the parent is pinctrl-msm.c
so that will in turn unconditionally call
irq_chip_eoi_parent() again, but its parent is invalid
so we get the following crash:
Unnable to handle kernel NULL pointer dereference at
virtual address 00000010
pgd = (ptrval)
[00000010] *pgd=00000000
Internal error: Oops: 5 [#1] PREEMPT SMP ARM
(...)
PC is at irq_chip_eoi_parent+0x4/0x10
LR is at pm8xxx_irq_handler+0x1b4/0x2d8
If we solve this crash by avoiding to call up to
irq_chip_eoi_parent(), the machine will hang and get
reset by the watchdog, because of semantic issues,
probably inside irq_chip.
As a solution, just assign the .irq_eoi conditionally if
we are actually using a wakeup parent.

Do not depend on dwfl_module_addrsym() because it can fail on user-space
shared libraries.
Actually, same bug was fixed by commit 664fee3dc379 ("perf probe: Do not
use dwfl_module_addrsym if dwarf_diename finds symbol name"), but commit
07d369857808 ("perf probe: Fix wrong address verification) reverted to
get actual symbol address from symtab.
This fixes it again by getting symbol address from DIE, and only if the
DIE has only address range, it uses dwfl_module_addrsym().

When we put an event with multiple probes, perf-probe fails to delete
with filters. This comes from a failure to list up the event name
because of overwrapping its name.
To fix this issue, skip to list up the event which has same name.

ADD_CONFIG_TERM accesses term->weak, however, in get_config_chgs this
value is accessed outside of the list_for_each_entry and references
invalid memory. Add an argument for ADD_CONFIG_TERM for weak and set it
to false in the get_config_chgs case.
This bug was cause by clang's address sanitizer and libfuzzer. It can be
reproduced with a command line of:
perf stat -a -e i/bs,tsc,L2/o

Currently, the setup.py script detects the clang compiler only when invoked
with CC=clang. But when using a specific version (e.g. CC=clang-11), this
doesn't work correctly and wrong compiler flags are set, leading to build
errors.
To properly detect clang, invoke the compiler with -v and check the output.
The first line should start with "clang version ...".
Committer testing:

And here is how tools/perf/util/setup.py checks if the used clang has
options that the distro specific python extension building compiler
defaults:
if cc_is_clang:
from distutils.sysconfig import get_config_vars
vars = get_config_vars()
for var in ('CFLAGS', 'OPT'):
vars[var] = sub("-specs=[^ ]+", "", vars[var])
if not clang_has_option("-mcet"):
vars[var] = sub("-mcet", "", vars[var])
if not clang_has_option("-fcf-protection"):
vars[var] = sub("-fcf-protection", "", vars[var])
if not clang_has_option("-fstack-clash-protection"):
vars[var] = sub("-fstack-clash-protection", "", vars[var])
if not clang_has_option("-fstack-protector-strong"):
vars[var] = sub("-fstack-protector-strong", "", vars[var])
So "-fcf-protection=full" is used, clang-9 has this option and thus it
was kept, the perf python extension was built with it and the build
completed successfully.
