bc7b488b1d drm/i915/dmc: protect against reading random memory
While loading the DMC firmware we were double checking the headers made
sense, but in no place we checked that we were actually reading memory
we were supposed to. This could be wrong in case the firmware file is
truncated or malformed.

Before this patch:
	# ls -l /lib/firmware/i915/icl_dmc_ver1_07.bin
	-rw-r--r-- 1 root root  25716 Feb  1 12:26 icl_dmc_ver1_07.bin
	# truncate -s 25700 /lib/firmware/i915/icl_dmc_ver1_07.bin
	# modprobe i915
	# dmesg| grep -i dmc
	[drm:intel_csr_ucode_init [i915]] Loading i915/icl_dmc_ver1_07.bin
	[drm] Finished loading DMC firmware i915/icl_dmc_ver1_07.bin (v1.7)

i.e. it loads random data. Now it fails like below:
	[drm:intel_csr_ucode_init [i915]] Loading i915/icl_dmc_ver1_07.bin
	[drm:csr_load_work_fn [i915]] *ERROR* Truncated DMC firmware, rejecting.

	i915 0000:00:02.0: DMC firmware homepage: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915

Before reading any part of the firmware file, validate the input first.

ac543d7145 drm/i915: Report an earlier wedged event when suspending the engines
On i915_gem_load_power_context() we do care whether or not we succeed in
completing the switch back to the kernel context (via idling the
engines). Currently, we detect if an error occurs while we wait, but we
do not report one if it occurred beforehand (and the status of the
switch is undefined). Check the current terminally wedged status on
entering the wait, and report it after flushing the requests, as if it
had occurred during our own wait.

1fe2d6f94f drm/i915: Skip context_barrier emission for unused contexts
The intent was to skip unused HW contexts by checking ce->state.
However, this only works for execlists where the ppGTT pointers is
stored inside the HW context. For gen7, the ppGTT is alongside the
logical state and must be updated on all active engines but, crucially,
only on active engines. As we need different checks, and to keep
context_barrier_task() agnostic, pass in the predicate.

2c1c552526 drm/i915/dsi: Use a fuzzy check for burst mode clock check
Prior to this commit we fail to init the DSI panel on the GPD MicroPC:
https://www.indiegogo.com/projects/gpd-micropc-6-inch-handheld-industry-laptop#/

The problem is intel_dsi_vbt_init() failing with the following error:
*ERROR* Burst mode freq is less than computed

The pclk in the VBT panel modeline is 70000, together with 24 bpp and
4 lines this results in a bitrate value of 70000 * 24 / 4 = 420000.
But the target_burst_mode_freq in the VBT is 418000.

This commit works around this problem by adding an intel_fuzzy_clock_check
when target_burst_mode_freq < bitrate and setting target_burst_mode_freq to
bitrate when that checks succeeds, fixing the panel not working.

1d1b5490b9 drm/i915/gtt: Replace struct_mutex serialisation for allocation
Instead of relying on the caller holding struct_mutex across the
allocation, push the allocation under a tree of spinlocks stored inside
the page tables. Not only should this allow us to avoid struct_mutex
here, but it will allow multiple users to lock independent ranges for
concurrent allocations, and operate independently. This is vital for
pushing the GTT manipulation into a background thread where dependency
on struct_mutex is verboten, and for allowing other callers to avoid
struct_mutex altogether.

v2: Restore lost GEM_BUG_ON for removing too many PTE from
gen6_ppgtt_clear_range.

10d75f5428 drm/i915: Fix plane state dumps
Stop dumping plane->state for planes. That is the old state most of the
time and dumping stale information only serves to confuse people.
Instead dump the new state just for the planes included in the
operation. For now we'll include only the planes for the modeset/fastset
pipes in the dumps. But probably we want to dump them all eventually,
just not quite sure how to present that information nicely to the user.

And while at it let's dump a few more interesting bits from the state.

2833920d0e drm/i915: Dump failed crtc states during atomic check
Currently we're only dumping the failed crtc state if
intel_modeset_pipe_config() fails. Let's do the state
dump if anything else fails afterwards. The downside
is that we lose the immediate knowledge which crtc caused
the failure (unless a lower level function indicates it
with an additional debug print) but having the full state

d82b4b2621 drm/i915: Report all objects with allocated pages to the shrinker
Currently, we try to report to the shrinker the precise number of
objects (pages) that are available to be reaped at this moment. This
requires searching all objects with allocated pages to see if they
fulfill the search criteria, and this count is performed quite
frequently. (The shrinker tries to free ~128 pages on each invocation,
before which we count all the objects; counting takes longer than
unbinding the objects!) If we take the pragmatic view that with
sufficient desire, all objects are eventually reapable (they become
inactive, or no longer used as framebuffer etc), we can simply return
the count of pinned pages maintained during get_pages/put_pages rather
than walk the lists every time.

The downside is that we may (slightly) over-report the number of
objects/pages we could shrink and so penalize ourselves by shrinking
more than required. This is mitigated by keeping the order in which we
shrink objects such that we avoid penalizing active and frequently used
objects, and if memory is so tight that we need to free them we would
need to anyway.

v2: Only expose shrinkable objects to the shrinker; a small reduction in
not considering stolen and foreign objects.
v3: Restore the tracking from a "backup" copy from before the gem/ split

3b4fa9640c drm/i915: Track the purgeable objects on a separate eviction list
Currently the purgeable objects, I915_MADV_DONTNEED, are mixed in the
normal bound/unbound lists. Every shrinker pass starts with an attempt
to purge from this set of unneeded objects, which entails us doing a
walk over both lists looking for any candidates. If there are none, and
since we are shrinking we can reasonably assume that the lists are
full!, this becomes a very slow futile walk.

If we separate out the purgeable objects into own list, this search then
becomes its own phase that is preferentially handled during shrinking.
Instead the cost becomes that we then need to filter the purgeable list
if we want to distinguish between bound and unbound objects.

7ef5ef5cde drm/i915: add force_probe module parameter to replace alpha_support
The i915.alpha_support module parameter has caused some confusion along
the way. Add new i915.force_probe parameter to specify PCI IDs of
devices to probe, when the devices are recognized but not automatically
probed by the driver. The name is intended to reflect what the parameter
effectively does, avoiding any overloaded semantics of "alpha" and
"support".

The parameter supports "" to disable, "<pci-id>,[<pci-id>,...]" to
enable force probe for one or more devices, and "*" to enable force
probe for all known devices.

Also add new CONFIG_DRM_I915_FORCE_PROBE config option to replace the
DRM_I915_ALPHA_SUPPORT option. This defaults to "*" if
DRM_I915_ALPHA_SUPPORT=y.

Instead of replacing i915.alpha_support immediately, let the two coexist
for a while, with a deprecation message, for a transition period.

7f5f228008 drm/i915/gtt: Avoid overflowing the WC stash
An interesting issue cropped with making the pagetables be allocated and
freed concurrently (i.e. removing their grandeous struct_mutex guard)
was that we would overflow the page stash. This happens when we have
multiple allocators grabbing WC pages such that we fill the vm's local
page stash and then when we free another page, the page stash is already
full and we overflow.

The fix is quite simple: to check for a full page stash before adding
another. This results in us keeping a vm local page stash around for
much longer, which is both a blessing and a curse.

This reverts commit 1ac159e23c ("drm/i915: Expand subslice mask"),
which kills ICL due to GEM_BUG_ON() sanity checks before CI even gets a

The commit exposes an issue in commit 1e40d4aea5 ("drm/i915/cnl:

also need to be addressed.

There's a proposed fix [1], but considering the seeming uncertainty with
the fix as well as the size of the regressing commit (in this context,
the one that actually brings down ICL), this warrants a revert to get
ICL working, and gives us time to get all of this right without
rushing. Even if this means shooting the messenger.

0c1f845772 drm/i915: Avoid refcount_inc on known zero count
In intel_wakeref_auto, we use refcount_inc_not_zero to detect the first
use and initialise the timer. On doing so, we have to avoid using
refcount_inc on that zero count as the debug code flags that as an
error:
	refcount_t: increment on 0; use-after-free.

Rearrange the code so that if we know the count is 0 and we are
initialising, we explicitly set it to 1.

then calculated:
  slice * subslice stride + subslice index / 8

a2904ade3d drm/i915/guc: Don't allow GuC submission
Due to the upcoming changes to the GuC ABI interface, we must
disable GuC submission mode until final ABI will be available
on all GuC firmwares.

To avoid regressions on systems configured to run with no longer
supported configuration "enable_guc=3" or "enable_guc=1" clear
GuC submission bit.

v2: force switch to non-GuC submission mode
v3: use GEM_BUG_ON (Joonas)

cc80b2ef24 drm/i915/guc: Change platform default GuC mode
Today our most desired GuC configuration is to only enable HuC
if it is available (as we need authenticated HuC firmware to enable
all media codecs on the hardware) and we really don't care about
having GuC submission enabled.

Change platform default GuC mode to match our goal, but note that
we still don't change default modparam value (GuC/HuC disabled).

b27e35ae5b drm/i915: Keep user GGTT alive for a minimum of 250ms
Do not allow runtime pm autosuspend to remove userspace GGTT mmaps too
quickly. For example, igt sets the autosuspend delay to 0, and so we
immediately attempt to perform runtime suspend upon releasing the
wakeref. Unfortunately, that involves tearing down GGTT mmaps as they
require an active device.

Override the autosuspend for GGTT mmaps, by keeping the wakeref around
for 250ms after populating the PTE for a fresh mmap.

v2: Prefer refcount_t for its under/overflow error detection
v3: Flush the user runtime autosuspend prior to system system.

c457d9cf25 drm/i915: Make sure we have enough memory bandwidth on ICL
ICL has so many planes that it can easily exceed the maximum
effective memory bandwidth of the system. We must therefore check
that we don't exceed that limit.

The algorithm is very magic number heavy and lacks sufficient
explanation for now. We also have no sane way to query the
memory clock and timings, so we must rely on a combination of
raw readout from the memory controller and hardcoded assumptions.
The memory controller values obviously change as the system
jumps between the different SAGV points, so we try to stabilize
it first by disabling SAGV for the duration of the readout.

The utilized bandwidth is tracked via a device wide atomic
private object. That is actually not robust because we can't
afford to enforce strict global ordering between the pipes.
Thus I think I'll need to change this to simply chop up the
available bandwidth between all the active pipes. Each pipe
can then do whatever it wants as long as it doesn't exceed
its budget. That scheme will also require that we assume that
any number of planes could be active at any time.

TODO: make it robust and deal with all the open questions

v2: Sleep longer after disabling SAGV
v3: Poll for the dclk to get raised (seen it take 250ms!)
    If the system has 2133MT/s memory then we pointlessly
    wait one full second :(
v4: Use the new pcode interface to get the qgv points rather
    that using hardcoded numbers
v5: Move the pcode stuff into intel_bw.c (Matt)
    s/intel_sagv_info/intel_qgv_info/
    Do the NV12/P010 as per spec for now (Matt)

Ville noticed this issue already earlier and managed to work around it
by keeping AUX-A always powered whenever AUX-B was used. He also
reported the issue to HW folks and they have now root caused the problem
and updated BSpec with a fix (see internal BSpec/Index/21257,
HSD/1607152412).

I noticed the same error - even with the WA being applied - while doing
AUX transfers with Chamelium being connected with a DP cable to the
source but letting Chamelium imitate an unplug. This is probably some
unstandard way on Chamelium's behalf of disconnecting itself from the
AUX pins. For instance it could still pull on the AUX pins which would
prevent the source from detecting AUX timeouts in the proper way,
leading to the ERRORs or WARNs seen in the logs in the Reference: bug
below.

In case I disconnect the sink properly (the cable itself, not via the
Chamelium unplug xmlrpc command) then the AUX timeout signaling works
properly and so there won't be any ERRORs/WARNs emitted.

397049a030 drm/i915/gen11: enable support for headerless msgs
Setting bit5 (headerless msg for preemptible GPGPU context) of SAMPLER_MODE
register to enable support for the headless msgs on gen11. None of existing
use cases will be affected by this as this change makes both types of
message - headerless and w/ header supported at the same time. It also
complies with the new recommendation for the default bit value for the
next gen.

63e8dcdb4f drm/i915/gtt: Neuter the deferred unbind callback from gen6_ppgtt_cleanup
Having deferred the vma destruction to a worker where we can acquire the
struct_mutex, we have to avoid chasing back into the now destroyed
ppgtt. The pd_vma is special in having a custom unbind function to scan
for unused pages despite the VMA itself being notionally part of the
GGTT. As such, we need to disable that callback to avoid a
use-after-free.

This unfortunately blew up so early during boot that CI declared the
machine unreachable as opposed to being the major failure it was. Oops.

struct_mutex is vanquished, take a detour in gen6_ppgtt_cleanup to do
the i915_vma_destroy from inside a worker under the struct_mutex.

16668f486f drm/i915/dp: Change a link bandwidth computation for DP
Data M/N calculations were assumed a bpp as RGB format. But when we are
using YCbCr 4:2:0 output format on DP, we should change bpp calculations
as YCbCr 4:2:0 format. The pipe_bpp value was assumed RGB format,
therefore, it was multiplied with 3. But YCbCr 4:2:0 requires a multiplier
value to 1.5.
Therefore we need to divide pipe_bpp to 2 while DP output uses YCbCr4:2:0
format.
 - RGB format bpp = bpc x 3
 - YCbCr 4:2:0 format bpp = bpc x 1.5

But Link M/N values are calculated and applied based on the Full Clock for
YCbCr 4:2:0. And DP YCbCr 4:2:0 does not need to pixel clock double for
a dotclock caluation. Only for HDMI YCbCr 4:2:0 needs to pixel clock double
for a dot clock calculation.

It only affects dp and edp port which use YCbCr 4:2:0 output format.
And for now, it does not consider a use case of DSC + YCbCr 4:2:0.

v2:
  Addressed review comments from Ville.
  Remove a changing of pipe_bpp on intel_ddi_set_pipe_settings().
  Because the pipe is running at the full bpp, keep pipe_bpp as RGB
  even though YCbCr 4:2:0 output format is used.
  Add a link bandwidth computation for YCbCr4:2:0 output format.

v3:
  Addressed reivew comments from Ville.
  In order to make codes simple, it adds and uses intel_dp_output_bpp()

ec4401d389 drm/i915/dp: Add a support of YCBCR 4:2:0 to DP MSA
When YCBCR 4:2:0 outputs is used for DP, we should program YCBCR 4:2:0 to
MSA and VSC SDP.

As per DP 1.4a spec section 2.2.4.3 [MSA Field for Indication of Color
Encoding Format and Content Color Gamut] while sending YCBCR 420 signals
we should program MSA MISC1 fields which indicate VSC SDP for the Pixel
Encoding/Colorimetry Format.

v2: Block comment style fix.

v6:
  Fix an wrong setting of MSA MISC1 fields for Pixel Encoding/Colorimetry
  Format indication. As per DP 1.4a spec Table 2-96 [MSA MISC1 and MISC0
  Fields for Pixel Encoding/Colorimetry Format Indication]
  When MISC1, bit 6, is Set to 1, a Source device uses a VSC SDP to
  indicate the Pixel Encoding/Colorimetry Format. On the wrong version
  it set a bit 5 of MISC1, now it set a bit 6 of MISC1.

struct edp_vsc_psr to struct dp_sdp. And each SDP data blocks have
different usages, each SDP type has different reserved data blocks and
Video_Stream_Configuration Extension VESA SDP might use all of Data Blocks
as Extended INFORFRAME Data Byte. so it makes Data Block variables as

c5d3e39caa drm/i915: Engine discovery query
Engine discovery query allows userspace to enumerate engines, probe their
configuration features, all without needing to maintain the internal PCI
ID based database.

A new query for the generic i915 query ioctl is added named
DRM_I915_QUERY_ENGINE_INFO, together with accompanying structure
drm_i915_query_engine_info. The address of latter should be passed to the
kernel in the query.data_ptr field, and should be large enough for the
kernel to fill out all known engines as struct drm_i915_engine_info
elements trailing the query.

As with other queries, setting the item query length to zero allows
userspace to query minimum required buffer size.

Enumerated engines have common type mask which can be used to query all
hardware engines, versus engines userspace can submit to using the execbuf
uAPI.

Engines also have capabilities which are per engine class namespace of
bits describing features not present on all engine instances.

v2:
 * Fixed HEVC assignment.
 * Reorder some fields, rename type to flags, increase width. (Lionel)
 * No need to allocate temporary storage if we do it engine by engine.
   (Lionel)

v3:
 * Describe engine flags and mark mbz fields. (Lionel)
 * HEVC only applies to VCS.

v4:
 * Squash SFC flag into main patch.
 * Tidy some comments.

v5:
 * Add uabi_ prefix to engine capabilities. (Chris Wilson)
 * Report exact size of engine info array. (Chris Wilson)
 * Drop the engine flags. (Joonas Lahtinen)
 * Added some more reserved fields.
 * Move flags after class/instance.

v6:
 * Do not check engine info array was zeroed by userspace but zero the
   unused fields for them instead.

v7:
 * Simplify length calculation loop. (Lionel Landwerlin)

v8:
 * Remove MBZ comments where not applicable.
 * Rename ABI flags to match engine class define naming.
 * Rename SFC ABI flag to reflect it applies to VCS and VECS.
 * SFC is wired to even _logical_ engine instances.
 * SFC applies to VCS and VECS.
 * HEVC is present on all instances on Gen11. (Tony)
 * Simplify length calculation even more. (Chris Wilson)
 * Move info_ptr assigment closer to loop for clarity. (Chris Wilson)
 * Use vdbox_sfc_access from runtime info.
 * Rebase for RUNTIME_INFO.
 * Refactor for lower indentation.
 * Rename uAPI class/instance to engine_class/instance to avoid C++
   keyword.

v9:
 * Rebase for s/num_rings/num_engines/ in RUNTIME_INFO.

v10:
 * Use new copy_query_item.

v11:
 * Consolidate with struct i915_engine_class_instnace.

a88b6e4cba drm/i915: Allow specification of parallel execbuf
There is a desire to split a task onto two engines and have them run at
the same time, e.g. scanline interleaving to spread the workload evenly.
Through the use of the out-fence from the first execbuf, we can
coordinate secondary execbuf to only become ready simultaneously with
the first, so that with all things idle the second execbufs are executed
in parallel with the first. The key difference here between the new
EXEC_FENCE_SUBMIT and the existing EXEC_FENCE_IN is that the in-fence
waits for the completion of the first request (so that all of its
rendering results are visible to the second execbuf, the more common
userspace fence requirement).

Since we only have a single input fence slot, userspace cannot mix an
in-fence and a submit-fence. It has to use one or the other! This is not
such a harsh requirement, since by virtue of the submit-fence, the
secondary execbuf inherit all of the dependencies from the first
request, and for the application the dependencies should be common
between the primary and secondary execbuf.

ee1136908e drm/i915/execlists: Virtual engine bonding
Some users require that when a master batch is executed on one particular
engine, a companion batch is run simultaneously on a specific slave
engine. For this purpose, we introduce virtual engine bonding, allowing
maps of master:slaves to be constructed to constrain which physical
engines a virtual engine may select given a fence on a master engine.

For the moment, we continue to ignore the issue of preemption deferring
the master request for later. Ideally, we would like to then also remove
the slave and run something else rather than have it stall the pipeline.
With load balancing, we should be able to move workload around it, but
there is a similar stall on the master pipeline while it may wait for
the slave to be executed. At the cost of more latency for the bonded
request, it may be interesting to launch both on their engines in
lockstep. (Bubbles abound.)

Opens: Also what about bonding an engine as its own master? It doesn't
break anything internally, so allow the silliness.

v2: Emancipate the bonds
v3: Couple in delayed scheduling for the selftests
v4: Handle invalid mutually exclusive bonding
v5: Mention what the uapi does
