d331585306 drm/amdgpu: Set DPM_FLAG_NEVER_SKIP when enabling PM-runtime
Based on a similar patch from Rafael for radeon.

When using ATPX to control dGPU power, the state is not retained
across suspend and resume cycles by default.  This can probably
be loosened for Hybrid Graphics (_PR3) laptops where I think the
state is properly retained.

450d007d19 gpu: drm: radeon: Set DPM_FLAG_NEVER_SKIP when enabling PM-runtime
On HP ProBook 4540s, if PM-runtime is enabled in the radeon driver
and the direct-complete optimization is used for the radeon device
during system-wide suspend, the system doesn't resume.

Preventing direct-complete from being used with the radeon device by
setting the DPM_FLAG_NEVER_SKIP driver flag for it makes the problem
go away, which indicates that direct-complete is not safe for the
radeon driver in general and should not be used with it (at least
for now).

This fixes a regression introduced by commit c62ec4610c
("PM / core: Fix direct_complete handling for devices with no
callbacks") which allowed direct-complete to be applied to
devices without PM callbacks (again) which in turn unlocked
direct-complete for radeon on HP ProBook 4540s.

c8ce48f065 asm-generic: Make time32 syscall numbers optional
We don't want new architectures to even provide the old 32-bit time_t
based system calls any more, or define the syscall number macros.

Add a new __ARCH_WANT_TIME32_SYSCALLS macro that gets enabled for all
existing 32-bit architectures using the generic system call table,
so we don't change any current behavior.
Since this symbol is evaluated in user space as well, we cannot use
a Kconfig CONFIG_* macro but have to define it in uapi/asm/unistd.h.

On 64-bit architectures, the same system call numbers mostly refer to
the system calls we want to keep, as they already pass 64-bit time_t.

As new architectures no longer provide these, we need new exceptions
in checksyscalls.sh.

MIPS: dma-noncoherent: Remove bogus condition in dma_sync_phys()
Commit e36863a550 ("MIPS: HIGHMEM DMA on noncoherent MIPS32
processors") introduced code which:

  1) Calculates an offset within a page, by ANDing an address
     with ~PAGE_MASK.

  2) Checks whether that offset is >= PAGE_SIZE.

This check can never evaluate true, making the code it guards
unreachable. smatch spots bogus arithmetic resulting from the
impossible condition, resulting in the following warning:

  arch/mips/mm/dma-noncoherent.c:125
    dma_sync_phys() warn: mask and shift to zero

Fix this by removing the impossible to satisfy condition & the
unreachable code it guards.

MIPS: eBPF: Always return sign extended 32b values
The function prototype used to call JITed eBPF code (ie. the type of the
struct bpf_prog bpf_func field) returns an unsigned int. The MIPS n64
ABI that MIPS64 kernels target defines that 32 bit integers should
always be sign extended when passed in registers as either arguments or
return values.

This means that when returning any value which may not already be sign
extended (ie. of type REG_64BIT or REG_32BIT_ZERO_EX) we need to perform
that sign extension in order to comply with the n64 ABI. Without this we
see strange looking test failures from test_bpf.ko, such as:

  test_bpf: #65 ALU64_MOV_X:
    dst = 4294967295 jited:1 ret -1 != -1 FAIL (1 times)

Although the return value printed matches the expected value, this is
only because printf is only examining the least significant 32 bits of
the 64 bit register value we returned. The register holding the expected
value is sign extended whilst the v0 register was set to a zero extended
value by our JITed code, so when compared by a conditional branch
instruction the values are not equal.

We already handle this when the return value register is of type
REG_32BIT_ZERO_EX, so simply extend this to also cover REG_64BIT.

d19f856479 perf bpf: Add bpf_map dumper
At some point I'll suggest moving this to libbpf, for now I'll
experiment with ways to dump BPF maps set by events in 'perf trace',
starting with a very basic dumper for the current very limited needs
of the augmented_raw_syscalls code: dumping booleans.

Having functions that apply to the map keys and values and do table
lookup in things like syscall id to string tables should come next.

2f146b78d5 drm/i915: Attach colorspace property and enable modeset
This patch attaches the colorspace connector property to the
hdmi connector. Based on colorspace change, modeset will be
triggered to switch to new colorspace.

Based on colorspace property value create an infoframe
with appropriate colorspace. This can be used to send an
infoframe packet with proper colorspace value set which
will help to enable wider color gamut like BT2020 on sink.

This patch attaches and enables HDMI colorspace, DP will be
taken care separately.

v2: Merged the changes of creating infoframe as well to this
patch as per Maarten's suggestion.

v3: Addressed review comments from Shashank. Separated HDMI
and DP colorspaces as suggested by Ville and Maarten.

v4: Addressed Chris and Ville's review comments, and created a
common colorspace property for DP and HDMI, filtered the list
based on the colorspaces supported by the respective protocol
standard. Handle the default case properly.

v5: Merged the DP handling along with platform colorspace
handling as per Shashank's comments.

v6: Reverted to old design of exposing all colorspaces to
userspace as per Ville's review comment

v7: Fixed a checkpatch complaint, Addressed  Maarten' review
comment, updated the RB from Maarten and Jani's ack.

v8: Moved colorspace AVI Infoframe programming to drm core and
removed from driver as per Ville's suggestion.

v9: Added a check to only allow RGB colorpsaces to be set in
infoframe though the colorspace property. Since there is no output
csc property to control planar formats and it will be added later.
Changes for RGB->YUV conversion inside driver without userspace
knowledge is still supported. This is as per Ville's suggestion.

v10: Fixed an error in if check.

v11: Dropped the check for planar vs RGB and allow all the colorspaces.
Onus will be on userspace to pick whatever pipe output it is able to
drive.

v12: Added Ville's RB.

d2c6a40584 drm: Add HDMI colorspace property
Create a new connector property to program colorspace to sink
devices. Modern sink devices support more than 1 type of
colorspace like 601, 709, BT2020 etc. This helps to switch
based on content type which is to be displayed. The decision
lies with compositors as to in which scenarios, a particular
colorspace will be picked.

This will be helpful mostly to switch to higher gamut colorspaces
like BT2020 when the media content is encoded as BT2020. Thereby
giving a good visual experience to users.

The expectation from userspace is that it should parse the EDID
and get supported colorspaces. Use this property and switch to the
one supported. Sink supported colorspaces should be retrieved by
userspace from EDID and driver will not explicitly expose them.

Basically the expectation from userspace is:
 - Set up CRTC DEGAMMA/CTM/GAMMA to convert to some sink
   colorspace
 - Set this new property to let the sink know what it
   converted the CRTC output to.

v2: Addressed Maarten and Ville's review comments. Enhanced
the colorspace enum to incorporate both HDMI and DP supported
colorspaces. Also, added a default option for colorspace.

v3: Removed Adobe references from enum definitions as per
Ville, Hans Verkuil and Jonas Karlman suggestions. Changed
Default to an unset state where driver will assign the colorspace
is not chosen by user, suggested by Ville and Maarten. Addressed
other misc review comments from Maarten. Split the changes to
have separate colorspace property for DP and HDMI.

v4: Addressed Chris and Ville's review comments, and created a
common colorspace property for DP and HDMI, filtered the list
based on the colorspaces supported by the respective protocol
standard.

v5: Made the property creation helper accept enum list based on
platform capabilties as suggested by Shashank. Consolidated HDMI
and DP property creation in the common helper.

v6: Addressed Shashank's review comments.

v7: Added defines instead of enum in uapi as per Brian Starkey's
suggestion in order to go with string matching at userspace. Updated
the commit message to add more details as well kernel docs.

v8: Addressed Maarten's review comments.

v9: Removed macro defines from uapi as per Brian Starkey and Daniel
Stone's comments and moved to drm include file. Moved back to older
design with exposing all HDMI colorspaces to userspace since infoframe
capability is there even on legacy platforms, as per Ville's review
comments.

v10: Fixed sparse warnings, updated the RB from Maarten and Jani's ack.

v11: Addressed Ville's review comments. Updated the Macro naming and
added DCI-P3 colorspace as well, defined in CTA 861.G spec.

v12: Appended BT709 and SMPTE 170M with YCC information as per Ville's
review comment to be clear and not to be confused with RGB.

v13: Reorder the colorspace macros.

v14: Removed DP as of now, will be added later once full support is
enabled, as per Ville's suggestion. Added Ville's RB.

There is no reason to have three allocations of per-port data. Combine

Following patches will require more port-specific data, now there is a

03d309711d perf test: Fix failure of 'evsel-tp-sched' test on s390
Commit 489338a717 ("perf tests evsel-tp-sched: Fix bitwise operator")
causes test case 14 "Parse sched tracepoints fields" to fail on s390.

This test succeeds on x86.

In fact this test now fails on all architectures with type char treated
as type unsigned char.

The root cause is the signed-ness of character arrays in the tracepoints
sched_switch for structure members prev_comm and next_comm.

On s390 the output of:

 [root@m35lp76 perf]# cat /sys/kernel/debug/tracing/events/sched/sched_switch/format
 name: sched_switch
 ID: 287
 format:
   field:unsigned short common_type; offset:0; size:2;	signed:0;
   ...
   field:char prev_comm[16]; offset:8; size:16;	signed:0;
   ...
   field:char next_comm[16]; offset:40; size:16; signed:0;

reveals the character arrays prev_comm and next_comm are per
default unsigned char and have values in the range of 0..255.

On x86 both fields are signed as this output shows:
 [root@f29]# cat /sys/kernel/debug/tracing/events/sched/sched_switch/format
 name: sched_switch
 ID: 287
 format:
   field:unsigned short common_type; offset:0; size:2;	signed:0;
   ...
   field:char prev_comm[16]; offset:8; size:16;	signed:1;
   ...
   field:char next_comm[16]; offset:40; size:16; signed:1;

and the character arrays prev_comm and next_comm are per default signed
char and have values in the range of -1..127.  The implementation of
type char is architecture specific.

Since the character arrays in both tracepoints sched_switch and
sched_wakeup should contain ascii characters, simply omit the check for
signedness in the test case.

Output before:

  [root@m35lp76 perf]# ./perf test -F 14
  14: Parse sched tracepoints fields                        :
  --- start ---
  sched:sched_switch: "prev_comm" signedness(0) is wrong, should be 1
  sched:sched_switch: "next_comm" signedness(0) is wrong, should be 1
  sched:sched_wakeup: "comm" signedness(0) is wrong, should be 1
  ---- end ----
  14: Parse sched tracepoints fields                        : FAILED!
  [root@m35lp76 perf]#

Output after:

  [root@m35lp76 perf]# ./perf test -Fv 14
  14: Parse sched tracepoints fields                        :
  --- start ---

2a9e27408e gpio: mockup: rework debugfs interface
Modify the way the debugfs interface works in gpio-mockup. Introduce
the concept of dummy pull config which will keep the mockup lines in
known state. The pull values can be modified by writing to the debugfs
files corresponding to lines. Lines in input mode always report the
current pull value, lines in output mode change the line value but
it will revert back to the one specified by current pull when released.
