drm/xe/device: Convert register access to use xe_mmio

this is a device-wide operation.

drm/xe/pcode: Convert register access to use xe_mmio

drm/xe/irq: Convert register access to use xe_mmio

drm/xe: Switch MMIO interface to take xe_mmio instead of xe_gt
Since much of the MMIO register access done by the driver is to non-GT
registers, use of 'xe_gt' in these interfaces has been a long-standing
design flaw that's been hard to disentangle.
To avoid a flag day across the whole driver, munge the function names
and add temporary compatibility macros with the original function names
that can accept either the new xe_mmio or the old xe_gt structure as a
parameter. This will allow us to slowly convert parts of the driver
over to the new interface independently.

drm/xe: Adjust mmio code to pass VF substructure to SRIOV code
Although we want to break the GT-centric nature of the MMIO code in the
general driver, the SRIOV handling still relies on data in a VF
substructure of the GT. So add a GT backpointer, but name it
sriov_vf_gt to make it clear that it's only for this one specific
special case and will not be set or usable for anything else.
v2:
- Store backpointer to the GT itself rather than the SRIOV-specific
substructure. (Michal)

drm/xe: Add xe_tile backpointer to xe_mmio
Once MMIO operations stop being (incorrectly) tied to a GT, we'll still
need a backpointer for feature checks, message logging, and tracepoints.

output, while also providing access to the xe_device.

drm/xe: Move GSI offset adjustment fields into 'struct xe_mmio'
By moving the GSI adjustment fields into 'struct xe_mmio' we can replace
the GT's MMIO substructure with another instance of xe_mmio. At the
moment this means MMIO operations wind up pulling information from two
different places (the tile's xe_mmio for the iomap and the GT's xe_mmio
for the adjustment), but we'll address that in future patches.
The type headers change a bit with this change, meaning that various
files should be including xe_device_types.h instead of (or in addition
to) xe_gt_types.h.

drm/xe: Clarify size of MMIO region
xe_mmio currently has a size parameter that is assigned but never used
anywhere. The current values assigned appear to be the size of the BAR
region assigned for the tile (both for registers and other purposes such
as the GGTT). Since the current field isn't being used for anything,
change the assignments to 4MB (the size of the register region on all
current platform) and rename the field to 'regs_size' to more clearly
describe what it represents. We can use this value in later patches to
help ensure no register accesses accidentally go past the end of the
desired register space (which might not be caught easily if they still
fall within the iomap).

aggregated or disaggregated metrics via the particular OA configuration it
uses (programmed via DRM_XE_OBSERVATION_OP_ADD_CONFIG).
The system is turning off, and we should probably put the device
in a safe power state. We don't need to evict VRAM or suspend running
jobs to a safe state, as the device is rebooted anyway.
This does not imply the system is necessarily reset, as we can
kexec into a new kernel. Without shutting down, things like
USB Type-C may mysteriously start failing.
drm/xe: Remove runtime argument from display s/r functions
The previous change ensures that pm_suspend is only called when
suspending or resuming. This ensures no further bugs like those
in the previous commit.
drm/xe: Add a xe_bo subtest for shrinking / swapping
Add a subtest that tries to allocate twice the amount of
buffer object memory available, write data to it and then read
all the data back verifying data integrity.
In order to be able to do this on systems that
have no or not enough swap-space available, allocate some memory
as purgeable, and introduce a function to purge such memory from
the TTM swap_notify path.
this test is intended to add test coverage to the current

- Drop stale exynos file pattern from MAINTAINERS file
The old "exynos" directory is removed from MAINTAINERS as Samsung Exynos display bindings have been relocated. This resolves a warning from get_maintainers.pl about no files matching the outdated directory.
- Constify struct exynos_drm_ipp_funcs
By making struct exynos_drm_ipp_funcs constant, the patch enhances security by moving the structure to a read-only section of memory. This change results in a slight reduction in the data section size.

There are a handful of patches here that fix masks and skip

- Parking shared RCGs at a slow always on clk at registration time
breaks stuff.
USB host mode can't handle such a slow frequency and the serial
console gets all garbled when the UART clk is handed over to the

the UART clks and another one to skip parking the USB clk at
registration time.
- The Starfive PLL driver used for the CPU was busted causing cpufreq

Pull pwm fix from Uwe Kleine-König:
"Fix an off-by-one in the stm32 driver.
Hardware engineers tend to start counting at 1 while the software guys
usually start with 0. This isn't so nice because that results in
drivers where pwm device #2 needs to use the hardware registers with
index 3.
This was noticed by Fabrice Gasnier.
A small patch fixing that mismatch is the only change included here"

seem like real things, amdgpu, i915 and xe each have a bunch of fixes

get_stashed_dentry() tries to optimistically retrieve a stashed dentry
from a provided location. It needs to ensure to hold rcu lock before it
dereference the stashed location to prevent UAF issues. Use
rcu_dereference() instead of READ_ONCE() it's effectively equivalent
with some lockdep bells and whistles and it communicates clearly that
this expects rcu protection.

drm/xe: Update runtime detection of has_flat_ccs
It's confusing to have a *set* function that actually probes the
hardware rather than receiving a parameter. Rename it to *probe* along
with prefix removal and comment in the relevant places that the
has_flat_ccs flag may be overridden in runtime.
While at it, fix the mixed declaration of struct xe_gt.
Modify powergate enable condition based on the type of GT or presence of
media engines. Also have a copy of the value written to powergate enable
register.

drm/xe/pat: sanity check compression and coh_mode
There is an implicit assumption in the driver that compression and
coh_1way+ are mutually exclusive. If this is ever not true then userptr
and imported dma-buf from external device will have uncleared ccs state.
Add a build bug for this so we don't forget.

drm/xe: prevent potential UAF in pf_provision_vf_ggtt()
The node ptr can point to an already freed ptr, if we hit the path with
an already allocated node. We later dereference that pointer with:
xe_gt_assert(gt, !xe_ggtt_node_allocated(node));
which is a potential UAF. Fix this by not stashing the ptr for node.
Also since it is likely a bad idea to leave config->ggtt_region pointing
to a stale ptr, also set that to NULL by calling
pf_release_vf_config_ggtt() instead of pf_release_ggtt().
'struct exynos_drm_ipp_funcs' are not modified in these drivers.
Constifying this structure moves some data to a read-only section, so
increase overall security.

ASoC: Fixes for v6.11
A larger set of fixes than I'd like at this point, but mainly due to
people working on fixing module autoloading by adding missing exports of
ID tables rather than anything particularly concerning. There are some
other runtime fixes and quirks, and a tweak to the ABI definition for
SOF which ensures that a struct layout doesn't vary depending on the
architecture of the host.
