Hello cgroup experts,
I have a GPU device [1] that supports organizing its resources for the
purposes of supporting containers. I am attempting to determine how to
represent this in the upstream kernel, and I wonder if it fits in cgroups.
The device itself has a number of resource types –
Applied. Thanks!

Hi All,
Not sure if it has been reported but the mainline kernel shows a drm warning
on RPI4B.

The iommu-dma layer is now mostly encapsulated by iommu_dma_ops, with
only a couple more public interfaces left pertaining to MSI integration.
Since these depend on the main IOMMU API header anyway, move their
declarations there, taking the opportunity to update the half-baked
comments to proper
Although iommu-dma is a per-architecture chonce, that is currently
implemented in a rather haphazard way. Selecting from the arch Kconfig
was the original logical approach, but is complicated by having to
manage dependencies; conversely, selecting from drivers ends up hiding
the architecture
Hi All,
It's been a while now since iommu-dma grew from a library of DMA ops
helpers for arch code into something more abstracted and closely coupled
to the IOMMU API core, so it seemed about time to do some housekeeping
in the more neglected areas to reflect that.
The header reorganisation does

There was a misunderstanding in how firmware file compatibility should
be managed within i915. This has been clarified as:
i915 must support all existing firmware releases forever
new minor firmware releases should replace prior versions
only backwards compatibility
From: John Harrison
Going forwards, the intention is for GuC firmware files to be named
for their major version only and HuC firmware files to have no version
number in the name at all. This patch adds those entries for DG2 and
ADL-P/S.

And use it to store expectations about what the DRM drivers are
supposed to pass in the IGT test suite.
Also include a configuration file that points to the out-of-tree CI
scripts.
By storing the test expectations along the code we can make sure both
stay in sync with each other, and so we can
The alignment of damaged area was needed for the original udlfb driver
that tried to trim the superfluous copies between front and backend
buffers and handle data in long int. It's not the case for udl DRM
driver, hence we can omit the whole unneeded alignment, as well as the
dead code.
It's better to perform the sync at the very last of the suspend
instead of the pipe-disable function, so that we can catch all pending
URBs (if any).
While we're at it, drop the error code from udl_sync_pending_urb()
since we basically ignore it; instead, give a clear error message
indicating a

For further debugging and optimization purpose, allow users to adjust
the number of URBs via a new module parameter, numurbs.

A couple of error handlings forgot to process the URB completion.
Those are both with WARN_ON() so should be visible, but we must fix
them in anyway.

In the current design, udl_get_urb() may be called asynchronously
during the driver freeing its URL list via udl_free_urb_list().
The problem is that the sync is determined by comparing the urbs.count
and urbs.available fields, while we clear urbs.count field only once
after udl_free_urb_list()
It seems that the current size (4) for the URB list is too small on
some devices, and it resulted in the occasional stalls. Increase the
default URB list size to 20 for working around it.
