Rob Clark 17154addc5 drm/msm: Add MSM_SUBMIT_FENCE_SN_IN
Add a way for userspace to specify the sequence number fence used to
track completion of the submit.  As the seqno fence is simply an
incrementing counter which is local to the submitqueue, it is easy for
userspace to know the next value.

This is useful for native userspace drivers in a vm guest, as the guest
to host roundtrip can have high latency.  Assigning the fence seqno in
the guest userspace allows the guest to continue without waiting for
response from the host.

Rob Clark 90f45c42d7 drm/msm: Add SYSPROF param (v2)
Add a SYSPROF param for system profiling tools like Mesa's pps-producer
(perfetto) to control behavior related to system-wide performance
counter collection.  In particular, for profiling, one wants to ensure
that GPU context switches do not effect perfcounter state, and might
want to suppress suspend (which would cause counters to lose state).

v2: Swap the order in msm_file_private_set_sysprof() [sboyd] and
    initialize the sysprof_active refcount to one (because the under/
    overflow checking in refcount_t doesn't expect a 0->1 transition)
    meaning that values greater than 1 means sysprof is active.

Rob Clark f7ddbf5581 drm/msm: Add SET_PARAM ioctl
It was always expected to have a use for this some day, so we left a
placeholder.  Now we do.  (And I expect another use in the not too
distant future when we start allowing userspace to allocate GPU iova.)

Add KVM_CAP_PPC_AIL_MODE_3 to advertise the capability to set the AIL
resource mode to 3 with the H_SET_MODE hypercall. This capability
differs between processor types and KVM types (PR, HV, Nested HV), and
affects guest-visible behaviour.

QEMU will implement a cap-ail-mode-3 to control this behaviour[1], and
use the KVM CAP if available to determine KVM support[2].

Mukul Joshi 5bdd3eb253 drm/amdkfd: Remove unused old debugger implementation
Cleanup the kfd code by removing the unused old debugger
implementation.
The address watch was only ever implemented in the upstream
driver for GFXv7 (Kaveri). The user mode tools runtime using
this API was never open-sourced. Work on the old debugger
prototype that used this API has been discontinued years ago.
Only a small piece of resetting wavefronts is kept and
is moved to kfd_device_queue_manager.c.

Rajneesh Bhardwaj 3698807094 drm/amdkfd: CRIU Introduce Checkpoint-Restore APIs
Checkpoint-Restore in userspace (CRIU) is a powerful tool that can
snapshot a running process and later restore it on same or a remote
machine but expects the processes that have a device file (e.g. GPU)
associated with them, provide necessary driver support to assist CRIU
and its extensible plugin interface. Thus, In order to support the
Checkpoint-Restore of any ROCm process, the AMD Radeon Open Compute
Kernel driver, needs to provide a set of new APIs that provide
necessary VRAM metadata and its contents to a userspace component
(CRIU plugin) that can store it in form of image files.

This introduces some new ioctls which will be used to checkpoint-Restore
any KFD bound user process. KFD only allows ioctl calls from the same
process that opened the KFD file descriptor. Since these ioctls are
expected to be called from a KFD criu plugin which has elevated ptrace
attached privileges and CAP_CHECKPOINT_RESTORE capabilities attached with
the file descriptors so modify KFD to allow such calls.

Florian Westphal d1ca60efc5 netfilter: ctnetlink: disable helper autoassign
When userspace, e.g. conntrackd, inserts an entry with a specified helper,
its possible that the helper is lost immediately after its added:

ctnetlink_create_conntrack
  -> nf_ct_helper_ext_add + assign helper
    -> ctnetlink_setup_nat
      -> ctnetlink_parse_nat_setup
         -> parse_nat_setup -> nfnetlink_parse_nat_setup
	                       -> nf_nat_setup_info
                                 -> nf_conntrack_alter_reply
                                   -> __nf_ct_try_assign_helper

... and __nf_ct_try_assign_helper will zero the helper again.

Set IPS_HELPER bit to bypass auto-assign logic, its unwanted, just like
when helper is assigned via ruleset.

Dropped old 'not strictly necessary' comment, it referred to use of
rcu_assign_pointer() before it got replaced by RCU_INIT_POINTER().

NB: Fixes tag intentionally incorrect, this extends the referenced commit,
but this change won't build without IPS_HELPER introduced there.

Demi Marie Obenour 164666fa66 Improve docs for IOCTL_GNTDEV_MAP_GRANT_REF
--------------cKY3Ggs6VDUCSn4I6iN78sHA

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

The current implementation of gntdev guarantees that the first call to
IOCTL_GNTDEV_MAP_GRANT_REF will set @index to 0.  This is required to
use gntdev for Wayland, which is a future desire of Qubes OS.
Additionally, requesting zero grants results in an error, but this was
not documented either.  Document both of these.

Dmitry V. Levin c86d86131a Partially revert "net/smc: Add netlink net namespace support"
The change of sizeof(struct smc_diag_linkinfo) by commit 79d39fc503
("net/smc: Add netlink net namespace support") introduced an ABI
regression: since struct smc_diag_lgrinfo contains an object of
type "struct smc_diag_linkinfo", offset of all subsequent members
of struct smc_diag_lgrinfo was changed by that change.

As result, applications compiled with the old version
of struct smc_diag_linkinfo will receive garbage in
struct smc_diag_lgrinfo.role if the kernel implements
this new version of struct smc_diag_linkinfo.

Fix this regression by reverting the part of commit 79d39fc503 that
changes struct smc_diag_linkinfo.  After all, there is SMC_GEN_NETLINK
interface which is good enough, so there is probably no need to touch
the smc_diag ABI in the first place.

Marco Elver ddecd22878 perf: uapi: Document perf_event_attr::sig_data truncation on 32 bit architectures
Due to the alignment requirements of siginfo_t, as described in
3ddb3fd8cd ("signal, perf: Fix siginfo_t by avoiding u64 on 32-bit
architectures"), siginfo_t::si_perf_data is limited to an unsigned long.

However, perf_event_attr::sig_data is an u64, to avoid having to deal
with compat conversions. Due to being an u64, it may not immediately be
clear to users that sig_data is truncated on 32 bit architectures.

Add a comment to explicitly point this out, and hopefully help some
users save time by not having to deduce themselves what's happening.

Linus Torvalds bb37101b36 TTY/Serial driver fixes for 5.17-rc2
Here are some small bug fixes and reverts for reported problems with the
 tty core and drivers.  They include:
 	- revert the fifo use for the 8250 console mode.  It caused too
 	  many regressions and problems, and had a bug in it as well.
 	  This is being reworked and should show up in a later -rc1
 	  release, but it's not ready for 5.17
 	- rpmsg tty race fix
 	- restore the cyclades.h uapi header file.  Turns out a compiler
 	  test suite used it for some unknown reason.  Bring it back
 	  just for the parts that are used by the builder test so they
 	  continue to build.  No functionality is restored as no one
 	  actually has this hardware anymore, nor is it really tested.
 	- stm32 driver fixes
 	- n_gsm flow control fixes
 	- pl011 driver fix
 	- rs485 initialization fix
 
 All of these have been in linux-next this week with no reported
 problems.

ASoC: hdmi-codec: Fix OOB memory accesses
Correct size of iec_status array by changing it to the size of status
array of the struct snd_aes_iec958. This fixes out-of-bounds slab
read accesses made by memcpy() of the hdmi-codec driver. This problem
is reported by KASAN.

Paolo Bonzini dd6e631220 KVM: x86: add system attribute to retrieve full set of supported xsave states
Because KVM_GET_SUPPORTED_CPUID is meant to be passed (by simple-minded
VMMs) to KVM_SET_CPUID2, it cannot include any dynamic xsave states that
have not been enabled.  Probing those, for example so that they can be
passed to ARCH_REQ_XCOMP_GUEST_PERM, requires a new ioctl or arch_prctl.
The latter is in fact worse, even though that is what the rest of the
API uses, because it would require supported_xcr0 to be moved from the
KVM module to the kernel just for this use.  In addition, the value
would be nonsensical (or an error would have to be returned) until
the KVM module is loaded in.

Therefore, to limit the growth of system ioctls, add a /dev/kvm
variant of KVM_{GET,HAS}_DEVICE_ATTR, and implement it in x86
with just one group (0) and attribute (KVM_X86_XCOMP_GUEST_SUPP).

Alex Deucher 8cda7a4f96 drm/amdgpu/UAPI: add new CTX OP to get/set stable pstates
Add a new CTX ioctl operation to set stable pstates for profiling.
When creating traces for tools like RGP or using SPM or doing
performance profiling, it's required to enable a special
stable profiling power state on the GPU.  These profiling
states set fixed clocks and disable certain other power
features like powergating which may impact the results.

Historically, these profiling pstates were enabled via sysfs,
but this adds an interface to enable it via the CTX ioctl
from the application.  Since the power state is global
only one application can set it at a time, so if multiple
applications try and use it only the first will get it,
the ioctl will return -EBUSY for others.  The sysfs interface
will override whatever has been set by this interface.

Maciej W. Rozycki f23653fe64 tty: Partially revert the removal of the Cyclades public API
Fix a user API regression introduced with commit f76edd8f7c ("tty:
cyclades, remove this orphan"), which removed a part of the API and
caused compilation errors for user programs using said part, such as
GCC 9 in its libsanitizer component[1]:

.../libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc:160:10: fatal error: linux/cyclades.h: No such file or directory
  160 | #include <linux/cyclades.h>
      |          ^~~~~~~~~~~~~~~~~~
compilation terminated.
make[4]: *** [Makefile:664: sanitizer_platform_limits_posix.lo] Error 1

As the absolute minimum required bring `struct cyclades_monitor' and
ioctl numbers back then so as to make the library build again.  Add a
preprocessor warning as to the obsolescence of the features provided.

wangyong 5bf1828153 delayacct: track delays from memory compact
Delay accounting does not track the delay of memory compact.  When there
is not enough free memory, tasks can spend a amount of their time
waiting for compact.

To get the impact of tasks in direct memory compact, measure the delay
when allocating memory through memory compact.

Also update tools/accounting/getdelays.c:

    / # ./getdelays_next  -di -p 304
    print delayacct stats ON
