cc976dbc49 Samsung clock controller fixes for v6.8
Google GS101: Correct the input clock names to CMU MISC clock controller
 to match received review.  The review was initially missed and CMU MISC
 clock controller bindings, driver and DTS was merged into v6.8-rc1 with
 different names.  Nothing was released so far, so the bindings and
 driver can be still corrected to match review.

ff2071a7b7 bpf: Generate const static pointers for kernel helpers
The generated bpf_helper_defs.h file currently contains definitions
like this for the kernel helpers, which are static objects:

  static void *(*bpf_map_lookup_elem)(void *map, const void *key) = (void *) 1;

These work well in both clang and GCC because both compilers do
constant propagation with -O1 and higher optimization, resulting in
`call 1' BPF instructions being generated, which are calls to kernel
helpers.

However, there is a discrepancy on how the -Wunused-variable
warning (activated by -Wall) is handled in these compilers:

- clang will not emit -Wunused-variable warnings for static variables
  defined in C header files, be them constant or not constant.

- GCC will not emit -Wunused-variable warnings for _constant_ static
  variables defined in header files, but it will emit warnings for
  non-constant static variables defined in header files.

There is no reason for these bpf_helpers_def.h pointers to not be
declared constant, and it is actually desirable to do so, since their
values are not to be changed.  So this patch modifies bpf_doc.py to
generate prototypes like:

  static void *(* const bpf_map_lookup_elem)(void *map, const void *key) = (void *) 1;

This allows GCC to not error while compiling BPF programs with `-Wall
-Werror', while still being able to detect and error on legitimate
unused variables in the program themselves.

This change doesn't impact the desired constant propagation in neither
Clang nor GCC with -O1 and higher.  On the contrary, being declared as
constant may increase the odds they get constant folded when
used/referred to in certain circumstances.

Tested in bpf-next master.
No regressions.

f2e4040c82 libbpf: Add some details for BTF parsing failures
As CONFIG_DEBUG_INFO_BTF is default off the existing "failed to find

cryptic. Add a little more detail with the hope of helping users.

Before:
```
libbpf: failed to find valid kernel BTF
libbpf: Error loading vmlinux BTF: -3
```

After not accessible:
```
libbpf: kernel BTF is missing at '/sys/kernel/btf/vmlinux', was CONFIG_DEBUG_INFO_BTF enabled?
libbpf: failed to find valid kernel BTF
libbpf: Error loading vmlinux BTF: -3

646751d523 bpf: Use -Wno-error in certain tests when building with GCC
Certain BPF selftests contain code that, albeit being legal C, trigger
warnings in GCC that cannot be disabled.  This is the case for example
for the tests

  progs/btf_dump_test_case_bitfields.c
  progs/btf_dump_test_case_namespacing.c
  progs/btf_dump_test_case_packing.c
  progs/btf_dump_test_case_padding.c
  progs/btf_dump_test_case_syntax.c

which contain struct type declarations inside function parameter
lists.  This is problematic, because:

- The BPF selftests are built with -Werror.

- The Clang and GCC compilers sometimes differ when it comes to handle
  warnings.  in the handling of warnings.  One compiler may emit
  warnings for code that the other compiles compiles silently, and one
  compiler may offer the possibility to disable certain warnings, while
  the other doesn't.

In order to overcome this problem, this patch modifies the
tools/testing/selftests/bpf/Makefile in order to:

1. Enable the possibility of specifing per-source-file extra CFLAGS.
   This is done by defining a make variable like:

   <source-filename>-CFLAGS := <whateverflags>

   And then modifying the proper Make rule in order to use these flags
   when compiling <source-filename>.

2. Use the mechanism above to add -Wno-error to CFLAGS for the
   following selftests:

   progs/btf_dump_test_case_bitfields.c
   progs/btf_dump_test_case_namespacing.c
   progs/btf_dump_test_case_packing.c
   progs/btf_dump_test_case_padding.c
   progs/btf_dump_test_case_syntax.c

   Note the corresponding -CFLAGS variables for these files are
   defined only if the selftests are being built with GCC.

Note that, while compiler pragmas can generally be used to disable
particular warnings per file, this 1) is only possible for warning
that actually can be disabled in the command line, i.e. that have
-Wno-FOO options, and 2) doesn't apply to -Wno-error.

Tested in bpf-next master branch.
No regressions.

eef5c7b28d cxl/pci: Skip to handle RAS errors if CXL.mem device is detached
The PCI AER model is an awkward fit for CXL error handling. While the
expectation is that a PCI device can escalate to link reset to recover
from an AER event, the same reset on CXL amounts to a surprise memory
hotplug of massive amounts of memory.

At present, the CXL error handler attempts some optimistic error
handling to unbind the device from the cxl_mem driver after reaping some
RAS register values. This results in a "hopeful" attempt to unplug the
memory, but there is no guarantee that will succeed.

A subsequent AER notification after the memdev unbind event can no
longer assume the registers are mapped. Check for memdev bind before
reaping status register values to avoid crashes of the form:

 BUG: unable to handle page fault for address: ffa00000195e9100

fbaf59a9f5 selftests/bpf: Remove "&>" usage in the selftests
In s390, CI reported that the sock_iter_batch selftest
hits this error very often:

2024-01-26T16:56:49.3091804Z Bind /proc/self/ns/net -> /run/netns/sock_iter_batch_netns failed: No such file or directory
2024-01-26T16:56:49.3149524Z Cannot remove namespace file "/run/netns/sock_iter_batch_netns": No such file or directory
2024-01-26T16:56:49.3772213Z test_sock_iter_batch:FAIL:ip netns add sock_iter_batch_netns unexpected error: 256 (errno 0)

It happens very often in s390 but Manu also noticed it happens very
sparsely in other arch also.

It turns out the default dash shell does not recognize "&>"
as a redirection operator, so the command went to the background.
In the sock_iter_batch selftest, the "ip netns delete" went
into background and then race with the following "ip netns add"
command.

This patch replaces the "&> /dev/null" usage with ">/dev/null 2>&1"
and does this redirection in the SYS_NOFAIL macro instead of doing
it individually by its caller. The SYS_NOFAIL callers do not care
about failure, so it is no harm to do this redirection even if
some of the existing callers do not redirect to /dev/null now.

It touches different test files, so I skipped the Fixes tags
in this patch. Some of the changed tests do not use "&>"
but they use the SYS_NOFAIL, so these tests are also
changed to avoid doing its own redirection because
SYS_NOFAIL does it internally now.

13b3d6bdbe drm/amd/display: add debugfs disallow edp psr
[Why]
fix reading edp rx crc timeout failure. after
bootup, kernel setup psr with dpcd 0x170 = 5. this
notify rx psr enable and let rx fw start checking crc
for fw internal logic. rx fw may not update crc read
count within dpcd 0x246. read count is always 0. this
will lead tx crc reading timeout.

[How]
add debugfs to let test app to disbable rx crc
checking for rx internal logic. then test app can read
rx crc dpcd 0x246 successfully.
expected app sequence is as below:
1. disable eDP PHY and notify eDP rx with dpcd 0x600 = 2.
2. echo 0x1 /sys/kernel/debug/dri/0/eDP-X/disallow_edp_enter_psr
3. enable eDP PHY and notify eDP rx with dpcd 0x600 = 1 but
   without dpcd 0x170 = 5.
4. read crc from rx dpcd 0x270, 0x246, etc.
5. echo 0x0 /sys/kernel/debug/dri/0/eDP-X/disallow_edp_enter_psr.
   this will let eDP back to normal with psr setup dpcd 0x170 = 5.

fc9f47455a drm/amd/display: For FPO and SubVP/DRR configs program vmin/max sel
[Why & How]
For FPO and SubVP/DRR cases we need to ensure to program
OTG_V_TOTAL_MIN/MAX_SEL, otherwise stretching the vblank
in FPO / SubVP / DRR cases will not have any effect
and we could hit underflow / corruption.

dcbf438d48 drm/amd/display: Unify optimize_required flags and VRR adjustments
[why]
There is only a single call to dc_post_update_surfaces_to_stream
so there is no need to have two flags to control it. Unifying
this to a single flag allows dc_stream_adjust_vmin_vmax to skip
actual programming when there is no change required.

[how]
Remove wm_optimze_required flag and set only optimize_required in its
place.  Then in dc_stream_adjust_vmin_vmax, check that the stream timing
range matches the requested one and skip programming if they are equal.

d46fb0068c drm/amd/display: increased min_dcfclk_mhz and min_fclk_mhz
[why]
Originally, PMFW said min FCLK is 300Mhz, but min DCFCLK can be increased
to 400Mhz because min FCLK is now 600Mhz so FCLK >= 1.5 * DCFCLK hardware
requirement will still be satisfied. Increasing min DCFCLK addresses
underflow issues (underflow occurs when phantom pipe is turned on for some
Sub-Viewport configs).

[how]
Increasing DCFCLK by raising the min_dcfclk_mhz

05d3dfd3ed drm/amd/display: Wait before sending idle allow and after idle disallow
[Why]
We want acknowledgment of the driver idle disallow from DMCUB before
continuing with any further programming.

For idle allow we want to minimize the chance of DMCUB actively
interacing with other firmware components on the system (eg. PMFW)
at the same time.

[How]
Ensure that DMCUB isn't in the middle of processing other command
submissions prior to allowing idle and after disallowing idle by
inserting a wait before the allow and by changing the wait type for
the idle disallow.
