drm: Generalized NV Block Linear DRM format mod
Builds upon the existing NVIDIA 16Bx2 block linear
format modifiers by adding more "fields" to the
existing parameterized
DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK format modifier
macro that allow fully defining a unique-across-
all-NVIDIA-hardware bit layout using a minimal
set of fields and values. The new modifier macro
DRM_FORMAT_MOD_NVIDIA_BLOCK_LINEAR_2D is
effectively backwards compatible with the existing
macro, introducing a superset of the previously
definable format modifiers.
Backwards compatibility has two quirks. First,
the zero value for the "kind" field, which is
implied by the DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK
macro, must be special cased in drivers and
assumed to map to the pre-Turing generic kind of
0xfe, since a kind of "zero" is reserved for
linear buffer layouts on all GPUs.
Second, it is assumed backwards compatibility
is only needed when running on Tegra GPUs, and
specifically Tegra GPUs prior to Xavier. This
is based on two assertions:
-Tegra GPUs prior to Xavier used a slightly
different raw bit layout than desktop GPUs,
making it impossible to directly share block
linear buffers between the two.
-Support for the existing block linear modifiers
was incomplete, making them useful only for
exporting buffers created by nouveau and
importing them to Tegra DRM as framebuffers for
scan out. There was no support for adding
framebuffers using format modifiers in nouveau,
nor importing dma-buf/PRIME GEM objects into
nouveau userspace drivers with modifiers in Mesa.
Hence it is assumed the prior modifiers were not
intended for use on desktop GPUs, and as a
corollary, were not intended to support sharing
block linear buffers across two different NVIDIA
GPUs.
v2:
- Added canonicalize helper function
v3:
- Added additional bit to compression field to
support Tesla (NV5x,G8x,G9x,GT1xx,GT2xx) class
chips.

that the function is completely unused, it warns that it is used in some
expression within the file but that expression will be evaluated to a
constant or be optimized away in the final assembly, essentially making
it appeared used but really isn't. Usually, this happens when a function

will be evaluated at compile time and not be required to be emitted.
In this case, the function is only used in GEM_BUG_ON, which is defined
as BUILD_BUG_ON_INVALID, which intentionally follows this pattern. To
fix this warning, add __maybe_unused to make it clear that this is

drm/amdgpu: Add autodump debugfs node for gpu reset v8
When GPU got timeout, it would notify an interested part
of an opportunity to dump info before actual GPU reset.
A usermode app would open 'autodump' node under debugfs system

amdgpu would notify usermode app through wait_queue_head and give
it 10 minutes to dump info.
After usermode app has done its work, this 'autodump' node is closed.
On node closure, amdgpu gets to know the dump is done through
the completion that is triggered in release().
There is no write or read callback because necessary info can be
obtained through dmesg and umr. Messages back and forth between
usermode app and amdgpu are unnecessary.
v2: (1) changed 'registered' to 'app_listening'
(2) add a mutex in open() to prevent race condition
v3 (chk): grab the reset lock to avoid race in autodump_open,
rename debugfs file to amdgpu_autodump,
provide autodump_read as well,
style and code cleanups
v4: add 'bool app_listening' to differentiate situations, so that
the node can be reopened; also, there is no need to wait for
completion when no app is waiting for a dump.
v5: change 'bool app_listening' to 'enum amdgpu_autodump_state'
add 'app_state_mutex' for race conditions:
(1)Only 1 user can open this file node
(2)wait_dump() can only take effect after poll() executed.
(3)eliminated the race condition between release() and

drm/exynos: mixer: Fix enabling of the runtime power management
Runtime power management is essential for the Exynos Mixer driver
operation. It should be enabled before adding its DRM component, because
in some cases (when deferred probe takes place due to the IOMMU
availability) the DRM driver might be initialized directly from the
Mixer's component_add() call, what results in starting the driver
operation without enabling the runtime power management.

According to BSpec 53998, we should try to
restrict qgv points, which can't provide
enough bandwidth for desired display configuration.
Currently we are just comparing against all of
those and take minimum(worst case).
v2: Fixed wrong PCode reply mask, removed hardcoded
values.
v3: Forbid simultaneous legacy SAGV PCode requests and
restricting qgv points. Put the actual restriction
to commit function, added serialization(thanks to Ville)
to prevent commit being applied out of order in case of
nonblocking and/or nomodeset commits.
v4:
- Minor code refactoring, fixed few typos(thanks to James Ausmus)
- Change the naming of qgv point
masking/unmasking functions(James Ausmus).
- Simplify the masking/unmasking operation itself,
as we don't need to mask only single point per request(James Ausmus)
- Reject and stick to highest bandwidth point if SAGV
can't be enabled(BSpec)
v5:
- Add new mailbox reply codes, which seems to happen during boot
time for TGL and indicate that QGV setting is not yet available.
v6:
- Increase number of supported QGV points to be in sync with BSpec.
v7: - Rebased and resolved conflict to fix build failure.
- Fix NUM_QGV_POINTS to 8 and moved that to header file(James Ausmus)
v8: - Don't report an error if we can't restrict qgv points, as SAGV
can be disabled by BIOS, which is completely legal. So don't
make CI panic. Instead if we detect that there is only 1 QGV
point accessible just analyze if we can fit the required bandwidth
requirements, but no need in restricting.
v9: - Fix wrong QGV transition if we have 0 planes and no SAGV
simultaneously.
v10: - Fix CDCLK corruption, because of global state getting serialized
without modeset, which caused copying of non-calculated cdclk
to be copied to dev_priv(thanks to Ville for the hint).
v11: - Remove unneeded headers and spaces(Matthew Roper)
- Remove unneeded intel_qgv_info qi struct from bw check and zero

- Changed QGV error message to have more clear meaning(Matthew Roper)
- Use state->modeset_set instead of any_ms(Matthew Roper)
- Moved NUM_SAGV_POINTS from i915_reg.h to i915_drv.h where it's used
- Keep using crtc_state->hw.active instead of .enable(Matthew Roper)
- Moved unrelated changes to other patch(using latency as parameter
for plane wm calculation, moved to SAGV refactoring patch)
v12: - Fix rebase conflict with own temporary SAGV/QGV fix.
- Remove unnecessary mask being zero check when unmasking
qgv points as this is completely legal(Matt Roper)
- Check if we are setting the same mask as already being set
in hardware to prevent error from PCode.
- Fix error message when restricting/unrestricting qgv points
to "mask/unmask" which sounds more accurate(Matt Roper)
- Move sagv status setting to icl_get_bw_info from atomic check
as this should be calculated only once.(Matt Roper)
- Edited comments for the case when we can't enable SAGV and
use only 1 QGV point with highest bandwidth to be more
understandable.(Matt Roper)

- Changed comment for zero new_mask in qgv points masking function
to better reflect reality(Ville Syrjälä)
- Simplified bit mask operation in qgv points masking function
(Ville Syrjälä)
- Moved intel_qgv_points_mask closer to gen11 SAGV disabling,
however this still can't be under modeset condition(Ville Syrjälä)
- Packed qgv_points_mask as u8 and moved closer to pipe_sagv_mask
(Ville Syrjälä)
- Extracted PCode changes to separate patch.(Ville Syrjälä)
- Now treat num_planes 0 same as 1 to avoid confusion and
returning max_bw as 0, which would prevent choosing QGV
point having max bandwidth in case if SAGV is not allowed,
as per BSpec(Ville Syrjälä)
- Do the actual qgv_points_mask swap in the same place as
all other global state parts like cdclk are swapped.
In the next patch, this all will be moved to bw state as
global state, once new global state patch series from Ville
lands
v14: - Now using global state to serialize access to qgv points
- Added global state locking back, otherwise we seem to read
bw state in a wrong way.

bw code.
v16: - Fixed intel_atomic_bw_* functions to be intel_bw_* as discussed

drm/i915: Fix enabled infoframe states of lspcon
Compared to implementation of DP and HDMI's encoder->infoframes_enabled,
the lspcon's implementation returns its active state. (we expect enabled
infoframe states of HW.) It leads to pipe state mismatch error
when ddi_get_config is called.
Because the current implementation of lspcon is not ready to support
readout infoframes, we need to return 0 here.
In order to support readout to lspcon, we need to implement read_infoframe
and infoframes_enabled. And set_infoframes also have to set an appropriate
bit on crtc_state->infoframes.enable

drm/i915/gt: Transfer old virtual breadcrumbs to irq_worker
The second try at staging the transfer of the breadcrumb. In part one,
we realised we could not simply move to the second engine as we were
only holding the breadcrumb lock on the first. So in commit
6c81e21a4742
("drm/i915/gt: Stage the transfer of the virtual breadcrumb"), we
removed it from the first engine and marked up this request to reattach
the signaling on the new engine. However, this failed to take into
account that we only attach the breadcrumb if the new request is added
at the start of the queue, which if we are transferring, it is because
we know there to be a request to be signaled (and hence we would not be
attached).
In this attempt, we try to transfer the completed requests to the
irq_worker on its rq->engine->breadcrumbs. This preserves the coupling
between the rq and its breadcrumbs, so that
i915_request_cancel_breadcrumb() does not attempt to manipulate the list
under the wrong lock.

drm/i915: Mark the addition of the initial-breadcrumb in the request
The initial-breadcrumb is used to mark the end of the awaiting and the
beginning of the user payload. We verify that we do not start the user
payload before all signaler are completed, checking our semaphore setup
by looking for the initial breadcrumb being written too early. We also
want to ensure that we do not add semaphore waits after we have already
closed the semaphore section, an issue for later deferred waits.
