References to i915_requests may be trapped by userspace inside a
sync_file or dmabuf (dma-resv) and held indefinitely across different
proceses. To counter-act the memory leaks, we try to not to keep
references from the request past their completion.
On the other side on fence release we need to know if rq->engine
is valid and points to hw engine (true for non-virtual requests).
To make it possible extra bit has been added to rq->execution_mask,
for marking virtual engines.

Developers can easily execute several tests on different devices
by just pushing their branch to their fork in a repository hosted
on gitlab.freedesktop.org which has an infrastructure to run jobs
in several runners and farms with different devices.
There are also other automated tools that uprev dependencies,
monitor the infra, and so on that are already used by the Mesa
project, and we can reuse them too.
Also, store expectations about what the DRM drivers are supposed
to pass in the IGT test suite. By storing the test expectations
along with the code, we can make sure both stay in sync with each
other so we can know when a code change breaks those expectations.
Also, include a configuration file that points to the out-of-tree
CI scripts.
This will allow all contributors to drm to reuse the infrastructure
already in gitlab.freedesktop.org to test the driver on several
generations of the hardware.

To reduce the guesswork a bit let's print out the SDVO

Each SDVO device can have up to three sets of DDC pins.
Currently we just register a single i2c_adapter for the
entire SDVO device and semi-randomly pick the "correct"
set of DDC pins during intel_sdvo_tmds_sink_detect().
This doesn't make any real sense especially if we have
multiple outputs each with their own dedicated DDC bus.
Let's clean up this mess and register a dedicated
i2c_adapter for each of the possible pin pairs. Each
output (ie. connector) can then pick the correct i2c_adapter
to use for its DDC bus. And we can just switch over to
drm_connector_init_with_ddc() to take care of the
connector->ddc association, which also populates the
"ddc" sysfs symlink as a bonus.
And now that things are based on the actual connector we can
also nuke the sketchy sdvo->controller_output thing.

We should switch over to the standard "ddc" per-connector
symlink instead of rolling our own thing. The i2c specific
symlink is also in the way of reworking the SDVO DDC handling

Instead of operating on the output the user specified (via the
connector) the current code tends to operate on whichever outputs
it has detected as attached. That is not how the kms uapi is supposed

operate on the output the user has specified.

Add FW definition and the matching override modparam.
The GSC FW has both a release version, based on platform and a rolling
counter, and a compatibility version, which is the one tracking
interface changes. Since what we care about is the interface, we use
the compatibility version in the binary names.
Same as with the GuC, a major version bump indicate a
backward-incompatible change, while a minor version bump indicates a
backward-compatible one, so we use only the former in the file name.

| type 'enum repaper_model' from 'const void *' [-Wvoid-pointer-to-enum-cast]

This is due to the fact that `match` is a void* while `enum repaper_model`
has the size of an int.
Add uintptr_t cast to silence clang warning while also keeping enum cast
for readability and consistency with other `model` assignment just a
few lines below:

Abstract the register access better. The DSPCNTR read could be moved to
either i9xx_plane.c or intel_color.c. The latter feels better, even if
the register is written in the former.

Because the gma_irq_install() is call after psb_gem_mm_init() function,
when psb_gem_mm_init() fails, the interrupt line haven't been allocated.
Yet the gma_irq_uninstall() is called in the psb_driver_unload() function
without checking if checking the irq is registered or not.

Patch series "New page table range API", v6.
This patchset changes the API used by the MM to set up page table entries.
The four APIs are:
set_ptes(mm, addr, ptep, pte, nr)
update_mmu_cache_range(vma, addr, ptep, nr)
flush_dcache_folio(folio)
flush_icache_pages(vma, page, nr)
flush_dcache_folio() isn't technically new, but no architecture
implemented it, so I've done that for them. The old APIs remain around
but are mostly implemented by calling the new interfaces.
The new APIs are based around setting up N page table entries at once.
The N entries belong to the same PMD, the same folio and the same VMA, so
ptep++ is a legitimate operation, and locking is taken care of for you.
Some architectures can do a better job of it than just a loop, but I have
hesitated to make too deep a change to architectures I don't understand
well.
One thing I have changed in every architecture is that PG_arch_1 is now a
per-folio bit instead of a per-page bit when used for dcache clean/dirty
tracking. This was something that would have to happen eventually, and it
makes sense to do it now rather than iterate over every page involved in a
cache flush and figure out if it needs to happen.
The point of all this is better performance, and Fengwei Yin has measured
improvement on x86. I suspect you'll see improvement on your architecture
too. Try the new will-it-scale test mentioned here:
https://lore.kernel.org/linux-mm/20230206140639.538867-5-fengwei.yin@intel.com/
You'll need to run it on an XFS filesystem and have
CONFIG_TRANSPARENT_HUGEPAGE set.
This patchset is the basis for much of the anonymous large folio work
being done by Ryan, so it's received quite a lot of testing over the last
few months.
This patch (of 38):
Determine if a value lies within a range more efficiently (subtraction +
comparison vs two comparisons and an AND). It also has useful (under some
circumstances) behaviour if the range exceeds the maximum value of the
type. Convert all the conflicting definitions of in_range() within the
kernel; some can use the generic definition while others need their own
definition.

Call *_calc_dpll_params() even in cases where the encoder has
computed the DPLL params for us.
The SDVO TV output code doesn't populate crtc_state->dpll.dot
leading to the dotclock getting calculated as zero, and that
leads to all kinds of real problems. The g4x DP code also
doesn't populate the derived dividers nor .vco, which could
also create some confusion.

Allow *_calc_dpll_params() to be called even if the N/P dividers
are zero without warning. We'll want to call these to make sure the
derived values are fully computed, but not all users (VLV DSI in
particular) even enable the DPLL and thus the dividers will
be left at zero.
It could also be possible that the BIOS has misprogrammed the DPLL
(IIRC happened with some SNB machines with 4k+ displays) and thus
we'll currently generate a lot of dmesg spew. Better be silent and
just let the normal state checker/etc. deal with any driver bugs.
