drm/msm/dpu: improve DSC allocation

At DSC V1.1 DCE (Display Compression Engine) contains a DSC encoder.
However, at DSC V1.2 DCE consists of two DSC encoders, one has an odd
index and another one has an even index. Each encoder can work
independently. But only two DSC encoders from same DCE can be paired
to work together to support DSC merge mode at DSC V1.2. For DSC V1.1
two consecutive DSC encoders (start with even index) have to be paired
to support DSC merge mode.  In addition, the DSC with even index have
to be mapped to even PINGPONG index and DSC with odd index have to be
mapped to odd PINGPONG index at its data path in regardless of DSC
V1.1 or V1.2. This patch improves DSC allocation mechanism with
consideration of those factors.

Changes in V6:
-- rename _dpu_rm_reserve_dsc_single to _dpu_rm_dsc_alloc
-- rename _dpu_rm_reserve_dsc_pair to _dpu_rm_dsc_alloc_pair
-- pass global_state to _dpu_rm_pingpong_next_index()
-- remove pp_max
-- fix for loop condition check at _dpu_rm_dsc_alloc()

Changes in V5:
-- delete dsc_id[]
-- update to global_state->dsc_to_enc_id[] directly
-- replace ndx with idx
-- fix indentation at function declaration
-- only one for loop at _dpu_rm_reserve_dsc_single()

Changes in V4:
-- rework commit message
-- use reserved_by_other()
-- add _dpu_rm_pingpong_next_index()
-- revise _dpu_rm_pingpong_dsc_check()

Changes in V3:
-- add dpu_rm_pingpong_dsc_check()
-- for pair allocation use i += 2 at for loop

Changes in V2:
    -- split _dpu_rm_reserve_dsc() into _dpu_rm_reserve_dsc_single() and
       _dpu_rm_reserve_dsc_pair()

drm/msm/dsi: stop calling set_split_display

Since the commit 8b03ad30e314 ("drm/msm/dsi: Use one connector for dual
DSI mode"), the second DSI host in the bonded pair will not be
associated with the encoder and will not get the bridges, thus making
condition in msm_dsi_manager_set_split_display() always false.

Technically that change broke bonded DSI support in the MDP5 driver. But
since nobody complained in the last 5.5 years, it seems that nobody
cares enough.

Drop the msm_dsi_manager_set_split_display() completely and stop calling
the set_split_display() KMS callback. Also remove the
msm_dsi::external_bridge field which was only used by the mentioned

drm: xlnx: zynqmp_dpsub: Filter interrupts against mask

Filter out status register against the interrupts' mask.

Some events are being reported via DP status register, even if
corresponding interrupts have been disabled. One instance of such event
leads to generation of VBLANK when the driver is in DRM bridge mode,
which in turn results in NULL pointer dereferencing. We should avoid
processing such events in an interrupt handler context.

This problem is less noticeable when the driver operates in DMA mode, as
in this case we have DRM CRTC object instantiated and DRM framework
simply discards unwanted VBLANKs in drm_handle_vblank().

drm: xlnx: zynqmp_dpsub: Make drm bridge discoverable

ZynqMP DPSUB supports 2 input modes: DMA based and live video.

In the first mode, the driver implements CRTC and DP encoder DRM bridge
to model the complete display pipeline. In this case, DRM bridge is
being directly instantiated within the driver, not using any bridge
discovery mechanisms.

In the live video input mode video signal is generated by FPGA fabric
and passed into DPSUB over the connected bus. In this mode driver
exposes the DP encoder as a DRM bridge, expecting external CRTC to
discover it via drm_of_find_panel_or_bridge() or a similar call. This
discovery relies on drm_bridge.of_node being properly set.

Assign device OF node to the bridge prior to registering it. This will
make said bridge discoverable by an external CRTC driver.

Merge tag 'trace-v6.8-rc2' of git://git./linux/kernel/git/trace/linux-trace

Pull tracing and eventfs fixes from Steven Rostedt:

 - Fix the return code for ring_buffer_poll_wait()

   It was returing a -EINVAL instead of EPOLLERR.

 - Zero out the tracefs_inode so that all fields are initialized.

   The ti->private could have had stale data, but instead of just
   initializing it to NULL, clear out the entire structure when it is
   allocated.

 - Fix a crash in timerlat

   The hrtimer was initialized at read and not open, but is canceled at
   close. If the file was opened and never read the close will pass a
   NULL pointer to hrtime_cancel().

 - Rewrite of eventfs.

   Linus wrote a patch series to remove the dentry references in the
   eventfs_inode and to use ref counting and more of proper VFS
   interfaces to make it work.

 - Add warning to put_ei() if ei is not set to free. That means
   something is about to free it when it shouldn't.

 - Restructure the eventfs_inode to make it more compact, and remove the
   unused llist field.

 - Remove the fsnotify*() funtions for when the inodes were being
   created in the lookup code. It doesn't make sense to notify about
   creation just because something is being looked up.

 - The inode hard link count was not accurate.

   It was being updated when a file was looked up. The inodes of
   directories were updating their parent inode hard link count every
   time the inode was created. That means if memory reclaim cleaned a
   stale directory inode and the inode was lookup up again, it would
   increment the parent inode again as well. Al Viro said to just have
   all eventfs directories have a hard link count of 1. That tells user
   space not to trust it.

  eventfs: Keep all directory links at 1

   affected by this hardware limitation.

   We got a reply that it affects all the SATA controllers in the
   ASM106x family, thus extend the existing 43-bit dma_mask quirk to

Input: i8042 - add Fujitsu Lifebook U728 to i8042 quirk table

Another Fujitsu-related patch.

In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728
refuses to work and it's not possible to type for example a dm-crypt
passphrase without the help of an external keyboard.

i8042.nomux kernel parameter resolves this issue but using that a PS/2
mouse is detected. This input device is unused even when the i2c-hid-acpi
kernel module is blacklisted making the integrated ELAN touchpad
(04F3:3092) not working at all.

So this notebook uses a hid-over-i2c touchpad which is managed by the
i2c_designware input driver. Since you can't find a PS/2 mouse port on this
computer and you can't connect a PS/2 mouse to it even with an official
port replicator I think it's safe to not use the PS/2 mouse port at all.

Input: i8042 - fix strange behavior of touchpad on Clevo NS70PU

When closing the laptop lid with an external screen connected, the mouse
pointer has a constant movement to the lower right corner. Opening the
lid again stops this movement, but after that the touchpad does no longer
register clicks.

The touchpad is connected both via i2c-hid and PS/2, the predecessor of
this device (NS70MU) has the same layout in this regard and also strange
behaviour caused by the psmouse and the i2c-hid driver fighting over
touchpad control. This fix is reusing the same workaround by just
disabling the PS/2 aux port, that is only used by the touchpad, to give the
i2c-hid driver the lone control over the touchpad.

dm-crypt, dm-verity: disable tasklets

Tasklets have an inherent problem with memory corruption. The function
tasklet_action_common calls tasklet_trylock, then it calls the tasklet
callback and then it calls tasklet_unlock. If the tasklet callback frees
the structure that contains the tasklet or if it calls some code that may
free it, tasklet_unlock will write into free memory.

The commits 8e14f610159d and d9a02e016aaf try to fix it for dm-crypt, but
it is not a sufficient fix and the data corruption can still happen [1].
There is no fix for dm-verity and dm-verity will write into free memory
with every tasklet-processed bio.

There will be atomic workqueues implemented in the kernel 6.9 [2]. They
will have better interface and they will not suffer from the memory
corruption problem.

But we need something that stops the memory corruption now and that can be
backported to the stable kernels. So, I'm proposing this commit that
disables tasklets in both dm-crypt and dm-verity. This commit doesn't
remove the tasklet support, because the tasklet code will be reused when
atomic workqueues will be implemented.

drm/imx/dcss: have all init functions use devres

dcss currently allocates and ioremaps quite a few resources in its probe
function's call graph. Devres now provides convenient functions which
perform the same task but do the cleanup automatically.

Port all memory allocations and ioremap() calls to the devres
counterparts.

drm/imx/dcss: request memory region

The driver's memory regions are currently just ioremap()ed, but not
reserved through a request. That's not a bug, but having the request is
a little more robust.

Implement the region-request through the corresponding managed
devres-function.

powerpc: iommu: Bring back table group release_ownership() call

The commit 2ad56efa80db ("powerpc/iommu: Setup a default domain and
remove set_platform_dma_ops") refactored the code removing the
set_platform_dma_ops(). It missed out the table group
release_ownership() call which would have got called otherwise
during the guest shutdown via vfio_group_detach_container(). On
PPC64, this particular call actually sets up the 32-bit TCE table,
and enables the 64-bit DMA bypass etc. Now after guest shutdown,
the subsequent host driver (e.g megaraid-sas) probe post unbind
from vfio-pci fails like,

megaraid_sas 0031:01:00.0: Warning: IOMMU dma not supported: mask 0x7fffffffffffffff, table unavailable
megaraid_sas 0031:01:00.0: Warning: IOMMU dma not supported: mask 0xffffffff, table unavailable
megaraid_sas 0031:01:00.0: Failed to set DMA mask
megaraid_sas 0031:01:00.0: Failed from megasas_init_fw 6539

The patch brings back the call to table_group release_ownership()
call when switching back to PLATFORM domain from BLOCKED, while
also separates the domain_ops for both.
