3edfa30f23 drm/msm/shrinker: Only iterate dontneed objs
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.

ab5c54cb88 drm/msm: Protect obj->active_count under obj lock
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.

70a59dd829 drm/<drivers>: Constify struct drm_driver
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:
- Improve commit message (Sam)

This *does* have the implication that userspace can try to shoot

the result will be about the same if they did madvise(DONTNEED) before
the submit ioctl, ie. they might not get want they want if they race

Before we remove dev->struct_mutex from the retire path, we have to deal
with the situation of a submit retiring before the submit ioctl returns.

To deal with this, ring->submits will hold a reference to the submit,
which is dropped when the submit is retired.  And the submit ioctl path
holds it's own ref, which it drops when it is done with the submit.

Also, add to submit list *after* getting/pinning bo's, to prevent badness
in case the completed fence is corrupted, and retire_worker mistakenly
believes the submit is done too early.

This also converts the special msm_gem_get_vaddr_active() to expect the

has the lock held, so it is more straightforward to just open-code the
locking for the other caller.

9184b6831b drm/msm: Do rpm get sooner in the submit path
Unfortunately, due to an dev_pm_opp locking interaction with
mm->mmap_sem, we need to do pm get before aquiring obj locks,
otherwise we can have anger lockdep with the chain:

  opp_table_lock --> &mm->mmap_sem --> reservation_ww_class_mutex

For an explicit fencing userspace, the impact should be minimal
as we do all the fence waits before this point.  It could result
in some needless resumes in error cases, etc.

b3d91800d9 drm/msm: Fix race condition in msm driver with async layer updates
When there are back to back commits with async cursor update,
there is a case where second commit can program the DPU hw
blocks while first didn't complete flushing config to HW.

Synchronize the compositions such that second commit waits
until first commit flushes the composition.

This change also introduces per crtc commit lock, such that
commits on different crtcs are not blocked by each other.

Changes in v2:
	- Use an array of mutexes in kms to handle commit
	  lock per crtc. (Rob Clark)

Changes in v3:
	- Add wrapper functions to handle lock and unlock of
	  commit_lock for each crtc. (Rob Clark)

drm/atomic: Pass the full state to CRTC atomic enable/disable
If the CRTC driver ever needs to access the full DRM state, it can't do so
at atomic_enable / atomic_disable time since drm_atomic_helper_swap_state
will have cleared the pointer from the struct drm_crtc_state to the struct
drm_atomic_state before calling those hooks.

In order to allow that, let's pass the full DRM state to atomic_enable and
atomic_disable. The conversion was done using the coccinelle script below,
built tested on all the drivers and actually tested on vc4.

Split out all the bits that are purely for dma_map_ops implementations
and related code into a new <linux/dma-map-ops.h> header so that they
don't get pulled into all the drivers.  That also means the architecture
specific <asm/dma-mapping.h> is not pulled in by <linux/dma-mapping.h>
any more, which leads to a missing includes that were pulled in by the
x86 or arm versions in a few not overly portable drivers.

9d8baa2bf2 drm/msm: Fix premature purging of BO
In the case where we have a back-to-back submission that shares the same
BO, this BO will be prematurely moved to inactive_list while retiring the
first submit. But it will be still part of the second submit which is
being processed by the GPU. Now, if the shrinker happens to be triggered at
this point, it will result in a premature purging of this BO.

To fix this, we need to refcount BO while doing submit and retire. Then,
it should be moved to inactive list when this refcount becomes 0.

We shouldn't be waiting for an event here with a timeout of 100ms when
we're not in the 'timeout' arm of the if condition. Instead we should be
sleeping in the interruptible state (S) until something happens and we
need to wakeup. Right now this kthread is running almost all the time
because it sleeps for 100ms, wakes up, sees there's nothing to do, and
then starts the process all over again. Looking at top it shows up in
the D state (uninterruptible) because it uses wait_event_timeout(). FIx
this up.

it if the current microcode version supports the new feature.

We can also re-enable preemption for those targets that support
CP_WHERE_AM_I. Start out by preemptively assuming that we can enable
preemption and disable it in a5xx_hw_init if the microcode version comes

7690a33f22 drm: msm: fix common struct sg_table related issues
The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the dma_map_sg().

struct sg_table is a common structure used for describing a non-contiguous
memory buffer, used commonly in the DRM and graphics subsystems. It
consists of a scatterlist with memory pages and DMA addresses (sgl entry),
as well as the number of scatterlist entries: CPU pages (orig_nents entry)
and DMA mapped pages (nents entry).

It turned out that it was a common mistake to misuse nents and orig_nents
entries, calling DMA-mapping functions with a wrong number of entries or
ignoring the number of mapped entries returned by the dma_map_sg()
function.

To avoid such issues, lets use a common dma-mapping wrappers operating
directly on the struct sg_table objects and use scatterlist page
iterators where possible. This, almost always, hides references to the
nents and orig_nents entries, making the code robust, easier to follow
and copy/paste safe.

5e0c22d4a9 drm/msm/a6xx: fix frequency not always being restored on GMU resume
The patch reorganizing the set_freq function made it so the gmu resume
doesn't always set the frequency, because a6xx_gmu_set_freq() exits early
when the frequency hasn't been changed. Note this always happens when
resuming GMU after recovering from a hang.

Use a simple workaround to prevent this from happening.

ccc862b957 drm/msm/dpu: Fix reservation failures in modeset
In TEST_ONLY commit, rm global_state will duplicate the
object and request for new reservations, once they pass
then the new state will be swapped with the old and will
be available for the Atomic Commit.

This patch fixes some of missing links in the resource
reservation sequence mentioned above.

1) Creation of duplicate state in test_only commit (Rob)
2) Allocate and release the resources on every modeset.
3) Avoid allocation only when active is false.

In a modeset operation, swap state happens well before
disable. Hence clearing reservations in disable will
cause failures in modeset enable.

Allow reservations to be cleared/allocated before swap,
such that only newly committed resources are pushed to HW.

Changes in v1:
 - Move the rm release to atomic_check.
 - Ensure resource allocation and free happens when active
   is not changed i.e only when mode is changed.(Rob)

Changes in v2:
 - Handle dpu_kms_get_global_state API failure as it may
   return EDEADLK (swboyd).

6d2b84a4e5 This tree adds the sched_set_fifo*() encapsulation APIs to remove
static priority level knowledge from non-scheduler code.
 
 The three APIs for non-scheduler code to set SCHED_FIFO are:
 
  - sched_set_fifo()
  - sched_set_fifo_low()
  - sched_set_normal()
 
 These are two FIFO priority levels: default (high), and a 'low' priority level,
 plus sched_set_normal() to set the policy back to non-SCHED_FIFO.
 
 Since the changes affect a lot of non-scheduler code, we kept this in a separate
 tree.
 
 When merging to the latest upstream tree there's a conflict in drivers/spi/spi.c,
 which can be resolved via:
 
 	sched_set_fifo(ctlr->kworker_task);

32d3e0fecc drm/msm: dsi: Use OPP API to set clk/perf state
On SDM845 and SC7180 DSI needs to express a performance state
requirement on a power domain depending on the clock rates.
Use OPP table from DT to register with OPP framework and use
dev_pm_opp_set_rate() to set the clk/perf state.

dev_pm_opp_set_rate() is designed to be equivalent to clk_set_rate()
for devices without an OPP table, hence the change works fine
on devices/platforms which only need to set a clock rate.

ca8199f134 drm/msm/dpu: ensure device suspend happens during PM sleep
"The PM core always increments the runtime usage counter
before calling the ->suspend() callback and decrements it
after calling the ->resume() callback"

DPU and DSI are managed as runtime devices. When
suspend is triggered, PM core adds a refcount on all the
devices and calls device suspend, since usage count is
already incremented, runtime suspend was not getting called
and it kept the clocks on which resulted in target not
entering into XO shutdown.

Add changes to force suspend on runtime devices during pm sleep.

Changes in v1:
 - Remove unnecessary checks in the function
    _dpu_kms_disable_dpu (Rob Clark).

Changes in v2:
 - Avoid using suspend_late to reset the usagecount
   as suspend_late might not be called during suspend
   call failures (Doug).

Changes in v3:
 - Use force suspend instead of managing device usage_count
   via runtime put and get API's to trigger callbacks (Doug).

Changes in v4:
 - Check the return values of pm_runtime_force_suspend and
   pm_runtime_force_resume API's and pass appropriately (Doug).

Changes in v5:
 - With v4 patch, test cycle has uncovered issues in device resume.

   On bubs: cmd tx failures were seen as SW is sending panel off
   commands when the dsi resources are turned off.

   Upon suspend, DRM driver will issue a NULL composition to the
   dpu, followed by turning off all the HW blocks.

   v5 changes will serialize the NULL commit and resource unwinding
   by handling them under PM prepare and PM complete phases there by
   ensuring that clks are on when panel off commands are being
   processed.

Changes in v6:
- Use drm_mode_config_helper_suspend/resume() instead of legacy API
  drm_atomic_helper_suspend/resume() (Doug).

  Trigger runtime callbacks from the suspend/resume call to turn
  off the resources.

Changes in v7:
- Add "__maybe_unused" to the functions to avoid compilation
  failures. Cleanup unnecessary configs (Doug).

51f644b40b drm/atomic-helper: reset vblank on crtc reset
Only when vblanks are supported ofc.

Some drivers do this already, but most unfortunately missed it. This
opens up bugs after driver load, before the crtc is enabled for the
first time. syzbot spotted this when loading vkms as a secondary
output. Given how many drivers are buggy it's best to solve this once
and for all in shared helper code.

Aside from moving the few existing calls to drm_crtc_vblank_reset into
helpers (i915 doesn't use helpers, so keeps its own) I think the
regression risk is minimal: atomic helpers already rely on drivers
calling drm_crtc_vblank_on/off correctly in their hooks when they
support vblanks. And driver that's failing to handle vblanks after
this is missing those calls already, and vblanks could only work by
accident when enabling a CRTC for the first time right after boot.

Big thanks to Tetsuo for helping track down what's going wrong here.

There's only a few drivers which already had the necessary call and
needed some updating:
- komeda, atmel and tidss also needed to be changed to call
  __drm_atomic_helper_crtc_reset() intead of open coding it
- tegra and msm even had it in the same place already, just code
  motion, and malidp already uses __drm_atomic_helper_crtc_reset().
- Laurent noticed that rcar-du and omap open-code their crtc reset and
  hence would actually be broken by this patch now. So fix them up by
  reusing the helpers, which brings the drm_crtc_vblank_reset() back.

Only call left is in i915, which doesn't use drm_mode_config_reset,
but has its own fastboot infrastructure. So that's the only case where
we actually want this in the driver still.

I've also reviewed all other drivers which set up vblank support with
drm_vblank_init. After the previous patch fixing mxsfb all atomic
drivers do call drm_crtc_vblank_on/off as they should, the remaining
drivers are either legacy kms or legacy dri1 drivers, so not affected
by this change to atomic helpers.

v2: Use the drm_dev_has_vblank() helper.

v3: Laurent pointed out that omap and rcar-du used drm_crtc_vblank_off
instead of drm_crtc_vblank_reset. Adjust them too.

v4: Laurent noticed that rcar-du and omap open-code their crtc reset
and hence would actually be broken by this patch now. So fix them up
by reusing the helpers, which brings the drm_crtc_vblank_reset() back.

v5: also mention rcar-du and ompadrm in the proper commit message
above (Laurent).

Previously the address space went from 16M to ~0u, but with the

Additionally, the new interface takes a start and size, not start and

bc8bd54ffd drm/msm: Fix 0xfffflub in "Refactor address space initialization"
This week I started seeing GPU crashes on my DragonBoard 845c
which I narrowed down to being caused by commit ccac7ce373
("drm/msm: Refactor address space initialization").

Looking through the patch, Jordan and I couldn't find anything
obviously wrong, so I ended up breaking that change up into a
number of smaller logical steps so I could figure out which part
was causing the trouble.

Ends up, visually counting 'f's is hard, esp across a number
of lines:
  0xfffffff != 0xffffffff

This patch corrects the end value we pass in to
msm_gem_address_space_create() in
adreno_iommu_create_address_space() so that it matches the value
used before the problematic patch landed.

With this change, I no longer see the GPU crashes that were
affecting me.

8b6b7d84bf drm/msm: Don't call dma_buf_vunmap without _vmap
I honestly don't exactly understand what's going on here, but the
current code is wrong for sure: It calls dma_buf_vunmap without ever
calling dma_buf_vmap.

What I'm not sure about is whether the WARN_ON is correct:
- msm imports dma-buf using drm_prime_sg_to_page_addr_arrays. Which is
  a pretty neat layering violation of how you shouldn't peek behind
  the curtain of the dma-buf exporter, but par for course. Note that
  all the nice new helpers don't (and we should probably have a bit a
  warning about this in the kerneldoc).

- but then in the get_vaddr() in msm_gem.c, we seems to happily wrap a
  vmap() around any object with ->pages set (so including imported
  dma-buf).

- I'm not seeing any guarantees that userspace can't use an imported
  dma-buf for e.g. MSM_SUBMIT_CMD_BUF in a5xx_submit_in_rb, so no
  guarantees that an imported dma-buf won't end up with a ->vaddr set.

But even if that WARN_ON is wrong, cleaning up a vmap() done by msm by
calling dma_buf_vunmap is the wrong thing to do.

v2: Rob said in review that we do indeed have a gap in get_vaddr() that
needs to be plugged. But the users I've found aren't legit users on
imported dma-buf, so we can just reject that.

ccac7ce373 drm/msm: Refactor address space initialization
Refactor how address space initialization works. Instead of having the
address space function create the MMU object (and thus require separate but
equal functions for gpummu and iommu) use a single function and pass the
MMU struct in. Make the generic code cleaner by using target specific
functions to create the address space so a2xx can do its own thing in its
own space.  For all the other targets use a generic helper to initialize
IOMMU but leave the door open for newer targets to use customization
if they need it.

52da6d5131 drm/msm: Attach the IOMMU device during initialization
Everywhere an IOMMU object is created by msm_gpu_create_address_space
the IOMMU device is attached immediately after. Instead of carrying around
the infrastructure to do the attach from the device specific code do it
directly in the msm_iommu_init() function. This gets it out of the way for
more aggressive cleanups that follow.

f7d33950cd drm/msm: remove _unlocked suffix in drm_gem_object_put_unlocked
Spelling out _unlocked for each and every driver is a annoying.
Especially if we consider how many drivers, do not know (or need to)
about the horror stories involving struct_mutex.

Just drop the suffix. It makes the API cleaner.

Done via the following script:

__from=drm_gem_object_put_unlocked
__to=drm_gem_object_put
for __file in $(git grep --name-only $__from); do
  sed -i  "s/$__from/$__to/g" $__file;

eecd7fd8bf drm/gem: add _locked suffix to drm_gem_object_put
Vast majority of DRM (core and drivers) are struct_mutex free.

As such we have only a handful of cases where the locked helper should
be used. Make that stand out a little bit better.

__to=drm_gem_object_put_locked

for __file in $(git grep --name-only --word-regexp $__from); do
  sed -i  "s/\<$__from\>/$__to/g" $__file;

d3b68ddf1d drm/msm/a4xx: add a405_registers for a405 device
A405 device has a different set of registers than a4xx_registers.  It
has no VMIDMT or XPU registers, and VBIF registers are different.  Let's
add a405_registers for a405 device.

As adreno_is_a405() works only after adreno_gpu_init() gets called, the
assignments get moved down after adreno_gpu_init().

dc0fa5eb76 drm/msm/a4xx: add adreno a405 support
It adds support for adreno a405 found on MSM8939.  The adreno_is_a430()
check in adreno_submit() needs an extension to cover a405.  The
downstream driver suggests it should cover the whole a4xx generation.
That's why it gets changed to adreno_is_a4xx(), while a420 is not
tested though.
