The iommu pgtable support is only available when IOMMU support
is built into the kernel:
WARNING: unmet direct dependencies detected for IOMMU_IO_PGTABLE
Depends on [n]: IOMMU_SUPPORT [=n]
Selected by [y]:
- DRM_MSM [=y] && HAS_IOMEM [=y] && DRM [=y] && (ARCH_QCOM [=y] || SOC_IMX5 || ARM && COMPILE_TEST [=y]) && OF [=y] && COMMON_CLK [=y] && MMU [=y] && (QCOM_OCMEM [=y] || QCOM_OCMEM [=y]=n)
Fix the dependency accordingly. There is no need for depending on
CONFIG_MMU any more, as that is implied by the iommu support.

nr_rings is reset to 1, but when this function is called for a second
(and third!) time nr_rings > 1 is false, thus the else case is entered
to set up a buffer for the RPTR shadow and consequently written to
RB_RPTR_ADDR, hanging platforms without WHERE_AM_I firmware support.
Restructure the condition in such a way that shadow buffer setup only
ever happens when has_whereami is true; otherwise preemption is only
finalized when the number of ring buffers has not been reset to 1 yet.

When using gem with vram carveout the page allocation is managed via
drm_mm. The necessary drm_mm_node is allocated in add_vma, but it is
referenced in msm_gem_object as well. It is freed before the drm_mm_node
has been deallocated leading to use-after-free on every single vram
allocation.
Currently put_iova is called before put_pages in both
msm_gem_free_object and msm_gem_purge:
put_iova -> del_vma -> kfree(vma) // vma holds drm_mm_node
/* later */
put_pages -> put_pages_vram -> drm_mm_remove_node(
msm_obj->vram_node)
// vram_node is a ref to
// drm_mm_node; in _msm_gem_new
It looks like del_vma does nothing else other than freeing the vma
object and removing it from it's list, so delaying the deletion should
be harmless.
This patch splits put_iova in put_iova_spaces and put_iova_vmas, so the
vma can be freed after the mm_node has been deallocated with the mm.
Note: The breaking commit separated the vma allocation from within
msm_gem_object to outside, so the vram_node reference became outside the
msm_gem_object allocation, and freeing order was therefore overlooked.

Some usb type-c dongle use irq_hpd request to perform device connection

disconnection are based on the state of hpd_state and sink_count.

-- fix kernel test robot complaint
Changes in V3:

Update the qos remap only if the client type changes for the plane.
This will avoid unnecessary register programming and also avoid log
spam from the dpu_vbif_set_qos_remap() function.

Mapping the imported pages of a DMA-buf into an userspace process
doesn't work as expected.
But we have reoccurring requests on this approach, so split the
functions for this and document that dma_buf_mmap() needs to be used
instead.

v3: rebased on latest changes

In case of panels with low vertical back porch, the prefill bw
requirement will be high as we will have less time(vbp+pw) to
fetch and fill the hw latency buffers before start of first line
in active period.
For ex:
Say hw_latency_line_buffers = 24, and if blanking vbp+pw = 10
Here we need to fetch 24 lines of data in 10 line times.
This will increase the bw to the ratio of linebuffers to blanking.
DPU hw can also fetch data during vertical front porch provided
interface prefetch is enabled. Use vfp in the prefill calculation
as dpu driver enables prefetch if the blanking is not sufficient
to fill the latency lines.

The last level system cache can be partitioned to 32 different
slices of which GPU has two slices preallocated. One slice is
used for caching GPU buffers and the other slice is used for
caching the GPU SMMU pagetables. This talks to the core system
cache driver to acquire the slice handles, configure the SCID's
to those slices and activates and deactivates the slices upon
GPU power collapse and restore.
Some support from the IOMMU driver is also needed to make use
of the system cache to set the right TCR attributes. GPU then
has the ability to override a few cacheability parameters which
it does to override write-allocate to write-no-allocate as the
GPU hardware does not benefit much from it.
DOMAIN_ATTR_IO_PGTABLE_CFG is another domain level attribute used
by the IOMMU driver for pagetable configuration which will be used
to set a quirk initially to set the right attributes to cache the
hardware pagetables into the system cache.

In situations where the GPU is mostly idle, all or nearly all buffer
objects will be in the inactive list. But if the system is under memory
pressure (from something other than GPU), we could still get a lot of
shrinker calls. Which results in traversing a list of thousands of objs
and in the end finding nothing to shrink. Which isn't so efficient.
Instead split the inactive_list into two lists, one inactive objs which
are shrinkable, and a second one for those that are not. This way we
can avoid traversing objs which we know are not shrinker candidates.

Previously we only held obj lock in the _active_get() path, and relied
on atomic_dec_return() to not be racy in the _active_put() path where
obj lock was not held.
But this is a false sense of security. Unlike obj lifetime refcnt,
where you do not expect to *increase* the refcnt after the last put
(which would mean that something has gone horribly wrong with the
object liveness reference counting), the active_count can increase
again from zero. Racing _active_put()s and _active_get()s could leave
the obj on the wrong mm list.
But in the retire path, immediately after the _active_put(), the
_unpin_iova() would acquire obj lock. So just move the locking earlier
and rely on that to protect obj->active_count.

Some dongle will not clear LINK_STATUS_UPDATED bit after
DPCD read which cause link training failed. This patch
just read 6 bytes of DPCD link status from sink and return
without checking LINK_STATUS_UPDATED bit.
Only 8 bits are used to represent link rate at sinker DPCD.
The really link rate is 2.7Mb times the 8 bits value.
For example, 0x0A at DPCD is equal to 2.7Gb (10 * 2.7Mb).
This patch also convert 8 bits value of DPCD to really link
rate to fix worng link rate error during phy compliance test.

During suspend, dp host controller and hpd block are disabled due to
both ahb and aux clock are disabled. Therefore hpd plug/unplug interrupts
will not be generated. At dp_pm_resume(), reinitialize both dp host
controller and hpd block so that hpd plug/unplug interrupts will be
generated and handled by driver so that hpd connection state is updated
correctly. This patch will fix link training flaky issues.

at both dp_pm_suspend() and dp_pm_resume().
Changes in v3:

Clear the shadow rptr on suspend. Otherwise, when we resume, we can
have a stale value until CP_WHERE_AM_I executes. If we suspend near
the ringbuffer wraparound point, this can lead to a chicken/egg
situation where we are waiting for ringbuffer space to write the
CP_WHERE_AM_I (or CP_INIT) packet, because we mistakenly believe that
the ringbuffer is full (due to stale rptr value in the shadow).
Fixes errors like:
[drm:adreno_wait_ring [msm]] *ERROR* timeout waiting for space in ringbuffer 0
in the resume path.

Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support.
Subsequent patch will address this.
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the
platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is
maybe a bit too much, hence the num_ioctls assignment prevents a
const driver structure.
- arcpgu, because that is stuck behind a pending tiny-fication series
from me.
- legacy drivers, because legacy requires non-const drm_driver.
Note that for armada I also went ahead and made the ioctl array const.
Only cc'ing the driver people who've not been converted (everyone else
is way too much).
v2: Fix one misplaced const static, should be static const (0day)
v3:
