interconnect fixes for v5.18
This contains a fix for a reported issue on sc7180 platforms, where
one of the resources has been incorrectly modelled as both clock and
interconnect, which is causing a crash when both frameworks try to
manage it. Fix the same issue also on another platform that appears
to be affected by the same.

MHI fixes for v5.18
Couple of patches fixing the hibernation issue seen on MHI endpoint devices like
SDX65 modems:
- During hibernation, the host puts the device into D3cold after thaw() stage.
But at that time, the device would be in M0 state. So the device emits a
warning (not visible to the host but to device firmware only) stating invalid
transition. This is fixed by adding a poweroff() callback that puts the device
into M3 before D3cold.
- There is a possibility that the recovery worker might be running while trying
to powerdown the device. So flush the recovery worker before that.

Make sure not to set run_stop bit or link state change request while

The mmsys routing table of mt8195 vdosys0 has 2 DITHER components,
so mmsys need to add DDP_COMPONENT_DITHER1 and change all usages of
DITHER enum form DDP_COMPONENT_DITHER to DDP_COMPONENT_DITHER0.
But its header need to keep DDP_COMPONENT_DITHER enum
until drm/mediatek also changed it.

with newer use cases in which PS-GT configuration is managed by the

Tegra194 and Tegra234 SoCs have the erratum that causes walk cache
entries to not be invalidated correctly. The problem is that the walk
cache index generated for IOVA is not same across translation and
invalidation requests. This is leading to page faults when PMD entry is
released during unmap and populated with new PTE table during subsequent
map request. Disabling large page mappings avoids the release of PMD
entry and avoid translations seeing stale PMD entry in walk cache.
Fix this by limiting the page mappings to PAGE_SIZE for Tegra194 and
Tegra234 devices. This is recommended fix from Tegra hardware design
team.

PCI drivers in a multiplatform kernel, and requires a custom

Change the driver to use pci_remap_iospace() like PCI drivers do,
so the generic ioport access can work across platforms.
To actually use that code, we have to select CONFIG_PCI
here.

As the growing demand on ZSTD compressions, there have been requests
for the support of ZSTD-compressed firmware files, so here it is:
this patch extends the firmware loader code to allow loading ZSTD
files. The implementation is fairly straightforward, it just adds a
ZSTD decompression routine for the file expander. (And the code is
even simpler than XZ thanks to the ZSTD API that gives the original
decompressed size from the header.)

Since the commit 948fb0969eae ("clk: Always clamp the rounded rate"),
the clk_core_determine_round_nolock() would clamp the requested rate
between min and max rates from the rate request. Normally these fields
would be filled by clk_core_get_boundaries() called from
clk_round_rate().
However clk_gfx3d_determine_rate() uses a manually crafted rate request,
which did not have these fields filled. Thus the requested frequency
would be clamped to 0, resulting in weird frequencies being requested
from the hardware.
Fix this by filling min_rate and max_rate to the values valid for the
respective PLLs (0 and ULONG_MAX).

Intel server platforms that support 'RAID', i.e. have platform firmware
support for software-RAID metadata + features that the kernel also
understands, maintain the same device-ids for RAID from generation to
generation. This is in contrast to client platforms that have tended to
roll new device-ids every platform generation. However, even though
server platform keep the ids there are still unique device-ids per
controller instance. To date there have only been 2 controllers on these
platforms, but platforms code named Emmitsburg add a third controller.
Add the device-id for this third controller and collect it with the
other generic server RAID ids.
As mentioned here [1], the pain of continuing add new and different
device-ids for RAID mode to this file [2] has been heard. Ideally this
device-id would not matter and the class code would remain
PCI_CLASS_STORAGE_SATA_AHCI regardless of the RAID mode, but other
operating systems depend on the class code *not* being AHCI when the
device is in RAID mode. That said, going forward there is little reason
for new server RAID ids to be added as they can simply reuse one of the
existing ids even for a new controller. Server software RAID features
continue to be supported on Linux. Client software RAID features
continue to be not supported and the recommendation there remains to set
the device to AHCI mode in platform firmware.

The configuration for mt8192 was incorrectly using the output formats
from mt8173. Since the output formats for mt8192 are instead the same
ones as for mt8183, which require two bus samples per pixel, the
pixelclock and DDR edge setting were misconfigured. This made external
displays unable to show the image.
Fix the issue by correcting the output format for mt8192 to be the same
as for mt8183, fixing the usage of external displays for mt8192.

simple_ondemand interacts poorly with clamp_to_idle. It only looks at
the load since the last get_dev_status call, while it should really look
at the load over polling_ms. When clamp_to_idle true, it almost always
picks the lowest frequency on active because the gpu is idle between
msm_devfreq_idle/msm_devfreq_active.
This logic could potentially be moved into devfreq core.

It is redundant since commit 7c0ffcd40b16 ("drm/msm/gpu: Respect PM QoS
constraints") because dev_pm_qos_update_request triggers get_dev_status.

The motivation at this point is mainly native userspace mesa driver in a
VM guest. The one remaining synchronous "hotpath" is buffer allocation,
because guest needs to wait to know the bo's iova before it can start
emitting cmdstream/state that references the new bo. By allocating the
iova in the guest userspace, we no longer need to wait for a response
from the host, but can just rely on the allocation request being
processed before the cmdstream submission. Allocation failures (OoM,
etc) would just be treated as context-lost (ie. GL_GUILTY_CONTEXT_RESET)
or subsequent allocations (or readpix, etc) can raise GL_OUT_OF_MEMORY.
v2: Fix inuse check
v3: Change mismatched iova case to -EBUSY

With userspace allocated iova (next patch), we can have a race condition
where userspace observes the fence completion and deletes the vma before
retire_submit() gets around to unpinning the vma. To handle this, add a
fenced unpin which drops the refcount but tracks the fence, and update
msm_gem_vma_inuse() to check any previously unsignaled fences.
v2: Fix inuse underflow (duplicate unpin)
v3: Fix msm_job_run() vs submit_cleanup() race condition

This way we only lookup vma once per object per submit, for both the

There was only a single user, which could just as easily stash the iova
when pinning.
