Similar to i915's commit cebc13de7e
("drm/i915: Whitelist COMMON_SLICE_CHICKEN3 for UMD access"), except
that instead of putting the register on the allowlist for UMD to
program, the KMD is doing the programming at context initialization
based on a queue creation flag.
This is a recommended tuning setting for both gen12 and Xe_HP
platforms.
If a render queue is created with
DRM_XE_EXEC_QUEUE_SET_STATE_CACHE_PERF_FIX, COMMON_SLICE_CHICKEN3 will
be programmed at initialization to enable the render color cache to
key with BTP+BTI (binding table pool + binding table entry) instead of
just BTI (binding table entry). This enables the UMD to avoid emitting
render-target-cache-flush + stall-at-pixel-scoreboard every time a
binding table entry pointing to a render target is changed.

This adds a function for retrieving the set of Locking objects enabled
for Single User Mode (SUM) and the value of the
RangeStartRangeLengthPolicy parameter.
It retrieves data from the LockingInfo table, specifically the
columns SingleUserModeRanges and RangeStartLengthPolicy, which
were added according to the TCG Opal Feature Set: Single User Mode,
as described in chapters 4.4.3.1 and 4.4.3.2.

In Single User Mode (SUM), if the RangeStartRangeLengthPolicy parameter

set up for SUM. All other attributes from struct opal_user_lr_setup

One the things the user has always keep in mind is that any user
pointers they put into an SQE is not going to be read by the kernel
until submission happens, and the user has to ensure the pointee stays
alive until then. For example, snippet below will lead to UAF of the on
stack variable ts. Instead of passing the timeout value as a pointer
allow to store it immediately in the SQE. The user has to set a new flag
called IORING_TIMEOUT_IMMEDIATE_ARG, in which case sqe->addr for timeout
or sqe->addr2 for timeout update requests will be interpreted as a time
value in nanosecods.
void prep_timeout(struct io_uring_sqe *sqe) {
struct __kernel_timespec ts = {...};
prep_timeout(sqe, &ts);
}
void submit() {
sqe = get_sqe();

This patch supports application allocated memory for CQs.
The application allocates and manages the CQs directly. To support
this, the driver exports a new comp_mask to indicate direct control
of the CQ. When this comp_mask bit is set in the ureq, the driver
maps this application allocated CQ memory into hardware. As the
application manages this memory, the CQ depth ('cqe') passed by it
must be used as is and the driver shouldn't update it.
For CQs, ib_core supports pinning dmabuf based application memory,
specified through provider attributes. This umem is mananged by the
ib_core and is available in ib_cq. Register 'create_cq_user' devop
to process this umem. The driver also supports the legacy interface
that allocates umem internally.

This flag can be set by drivers once they have finished auditing and
implementing the full udata support on every udata operation.
My intention going forward is that driver authors proposing new udata uAPI
for their drivers must first do the work and set this flag.
If this flag is not set the userspace should not try to use udata based
uAPI newer than this commit, though on a case by case basis it may be OK
based on what checks historical kernels performed on the specific call.
Since bnxt_re is audited now, it is the first driver to set the flag.

Introduces the DRM RAS infrastructure over generic netlink.
The new interface allows drivers to expose RAS nodes and their
associated error counters to userspace in a structured and extensible
way. Each drm_ras node can register its own set of error counters, which
are then discoverable and queryable through netlink operations. This
lays the groundwork for reporting and managing hardware error states
in a unified manner across different DRM drivers.
Currently it only supports error-counter nodes. But it can be
extended later.
The registration is also not tied to any drm node, so it can be
used by accel devices as well.
It uses the new and mandatory YAML description format stored in
Documentation/netlink/specs/. This forces a single generic netlink
family namespace for the entire drm: "drm-ras".
But multiple-endpoints are supported within the single family.
Any modification to this API needs to be applied to
Documentation/netlink/specs/drm_ras.yaml before regenerating the
code:

Support for dma scatter-gather mapping and is intended for testing
mapping performance. It achieves by introducing the dma_sg_map_param
structure and related functions, which enable the implementation of
scatter-gather mapping preparation, mapping, and unmapping operations.
Additionally, the dma_map_benchmark_ops array is updated to include
operations for scatter-gather mapping. This commit aims to provide
a wider range of mapping performance test to cater to different scenarios.

This patch adjusts the DMA map benchmark framework to make the DMA
map benchmark framework more flexible and adaptable to other mapping
modes in the future. By abstracting the framework into five interfaces:
prepare, unprepare, initialize_data, do_map, and do_unmap.
The new map schema can be introduced more easily
without major modifications to the existing code structure.

include/uapi/linux/dma-buf.h uses several macros from ioctl.h to define
its ioctl commands. However, it does not include ioctl.h itself. So,
if userspace source code tries to include the dma-buf.h file without
including ioctl.h, it can result in build failures.
Therefore, include ioctl.h in the dma-buf UAPI header.

Allow users to set FRMR pools aging timer through netlink.
This functionality will allow user to control how long handles reside in
the kernel before being destroyed, thus being able to tune the tradeoff
between memory and HW object consumption and memory registration
optimization.
Since FRMR pools is highly beneficial for application restart scenarios,
this command allows users to modify the aging timer to their application
restart time, making sure the FRMR handles deregistered on application
teardown are kept for long enough in the pools for reuse in the
application startup.

Add an extended feature flag NL80211_EXT_FEATURE_IEEE8021X_AUTH to
allow a driver to indicate support for the IEEE 802.1X authentication
protocol in non-AP STA mode, as defined in
"IEEE P802.11bi/D4.0, 12.16.5".
In case of SME in userspace, the Authentication frame body is prepared
in userspace while the driver finalizes the Authentication frame once
it receives the required fields and elements. The driver indicates
support for IEEE 802.1X authentication using the extended feature flag
so that userspace can initiate IEEE 802.1X authentication.
When the feature flag is set, process IEEE 802.1X Authentication frames
from userspace in non-AP STA mode. If the flag is not set, reject
IEEE 802.1X Authentication frames.
Define a new authentication type NL80211_AUTHTYPE_IEEE8021X for
IEEE 802.1X authentication.

When any incumbent signal is detected by an AP/mesh interface operating
in 6 GHz band, FCC mandates the AP/mesh to vacate the channels affected
by it [1].
Add a new API cfg80211_incumbent_signal_notify() that can be used
by mac80211 or drivers to notify the higher layers about the signal
interference event with the interference bitmap in which each bit
denotes the affected 20 MHz in the operating channel.
Add support for the new nl80211 event and nl80211 attribute as well to
notify userspace on the details about the interference event. Userspace is
expected to process it and take further action - vacate the channel, or
reduce the bandwidth.

-#define PCI_CAP_EXP_ENDPOINT_SIZEOF_V2 52 /* v2 endpoints with link end here */
+#define PCI_CAP_EXP_ENDPOINT_SIZEOF_V2 0x32 /* end of v2 EPs w/ link */
This broke PCI capabilities in a VMM because subsequent ones weren't
DWORD-aligned.
Change PCI_CAP_EXP_ENDPOINT_SIZEOF_V2 to the correct value of 0x34.
