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.

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.

These tables are not large or overbearing, so moving them into the
source file seems like the right thing to do. The alternative is to
use __maybe_unused, which is undesirable.

Aliases property name must include only lowercase and '-', so fix this
in the driver, so we're not tempted to do "ovl_2l0 = &ovl_2l0" in the
device-tree instead of the right one which is "ovl-2l0 = &ovl_2l0".

Prior to sanitizing the GGTT, the only operations allowed in
intel_display_init_nogem() are those to reserve the preallocated (and
active) regions in the GGTT leftover from the BIOS. Trying to allocate a
GGTT vma (such as intel_pin_and_fence_fb_obj during the initial modeset)
may then conflict with other preallocated regions that have not yet been
protected.
Move the initial modesetting from the end of init_nogem to the beginning
of init so that any vma pinning (either framebuffers or DSB, for example),
is after the GGTT is ready to handle it.
This will prevent the DSB object from being destroyed too early:

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in mediatek. The only exception is gem_prime_mmap,
which is non-trivial to convert.

Add a new iommu domain attribute DOMAIN_ATTR_IO_PGTABLE_CFG
for pagetable configuration which initially will be used to
set quirks like for system cache aka last level cache to be
used by client drivers like GPU to set right attributes for
caching the hardware pagetables into the system cache and
later can be extended to include other page table configuration
data.
