The bounds check on "index" doesn't catch negative values. Using
ARRAY_SIZE() directly is more readable and more robust because it prevents
negative values for "index". Fortunately we only pass valid values to
ipc_chnl_cfg_get() so this patch does not affect runtime.

In 69de4421bb4c ("drm/ttm: Initialize debugfs from
ttm_global_init()"), ttm_global_init was changed so that if creation
of the debugfs global root directory fails, ttm_global_init will bail
out early and return an error, leading to initialization failure of
DRM drivers. However, not every system will be using debugfs. On such
a system, debugfs directory creation can be expected to fail, but DRM
drivers must still be usable. This changes it so that if creation of
TTM's debugfs root directory fails, then no biggie: keep calm and
carry on.

Each completion ring entry has a valid bit to indicate that the entry
contains a valid completion event. The driver's main poll loop
__bnxt_poll_work() has the proper dma_rmb() to make sure the valid
bit of the next entry has been checked before proceeding further.
But when we call bnxt_rx_pkt() to process the RX event, the RX
completion event consists of two completion entries and only the
first entry has been checked to be valid. We need the same barrier
after checking the next completion entry. Add missing dma_rmb()
barriers in bnxt_rx_pkt() and other similar locations.
Fixes: 67a95e2022c7 ("bnxt_en: Need memory barrier when processing the completion ring.")

There is a known bug on BCM2711's SDHCI core integration where the
controller will hang when the difference between the core clock and the
bus clock is too great. Specifically this can be reproduced under the
following conditions:
- No SD card plugged in, polling thread is running, probing cards at
100 kHz.
- BCM2711's core clock configured at 500MHz or more.
So set 200 kHz as the minimum clock frequency available for that board.
For more information on the issue see this:

Syzbot reported slab-out-of bounds write in decode_data().
The problem was in missing validation checks.
Syzbot's reproducer generated malicious input, which caused
decode_data() to be called a lot in sixpack_decode(). Since
rx_count_cooked is only 400 bytes and noone reported before,
that 400 bytes is not enough, let's just check if input is malicious
and complain about buffer overrun.

The current_opp is released only when whole OPP table is released,
otherwise it's only marked as removed by dev_pm_opp_remove_table().
Functions like dev_pm_opp_put_clkname() and dev_pm_opp_put_supported_hw()
are checking whether OPP table is empty and it's not if current_opp is
set since it holds the refcount of OPP, this produces a noisy warning
from these functions about busy OPP table. Remove the checks to fix it.

In old variant irq_of_parse_and_map() returns zero if failed so

skbs are freed on error and not put on the ring. We may, however,
be in a situation where we're freeing the last skb of a batch,
and there is a doorbell ring pending because of xmit_more() being
true earlier. Make sure we ring the door bell in such situations.
Since errors are rare don't pay attention to xmit_more() and just
always flush the pending frames.
The busy case should be safe to be left alone because it can
only happen if start_xmit races with completions and they
both enable the queue. In that case the kick can't be pending.

We can't take the tx lock from the napi poll routine, because
netpoll can poll napi at any moment, including with the tx lock
already held.
The tx lock is protecting against two paths - the disable
path, and (as Michael points out) the NETDEV_TX_BUSY case
which may occur if NAPI completions race with start_xmit
and both decide to re-enable the queue.
For the disable/ifdown path use synchronize_net() to make sure
closing the device does not race we restarting the queues.
Annotate accesses to dev_state against data races.
For the NAPI cleanup vs start_xmit path - appropriate barriers
are already in place in the main spot where Tx queue is stopped
but we need to do the same careful dance in the TX_BUSY case.

The function tpci200_register called by tpci200_install and

tpci200_unregister has some cleanup operations not in the

many different double free issues.

During suspend/resume NGD remote instance is power cycled along
with remotely controlled bam dma engine.
So Reset the dma configuration during this suspend resume path
so that we are not dealing with any stale dma setup.
Without this transactions timeout after first suspend resume path.

For some reason we ended up using wrong device in some places for pm_runtime calls.
Fix this so that NGG driver can do runtime pm correctly.

In some usecases transaction ids are dynamically allocated inside
the controller driver after sending the messages which have generic
acknowledge responses. So check for this before refcounting pm_runtime.
Without this we would end up imbalancing runtime pm count by
doing pm_runtime_put() in both slim_do_transfer() and slim_msg_response()
for a single pm_runtime_get() in slim_do_transfer()

As tid is unsigned its hard to figure out if the tid is valid or
invalid. So Start the transaction ids from 1 instead of zero
so that we could differentiate between a valid tid and invalid tids
This is useful in cases where controller would add a tid for controller
specific transfers.

There is a TOCTOU issue in set_evtchn_to_irq. Rows in the evtchn_to_irq
mapping are lazily allocated in this function. The check whether the row
is already present and the row initialization is not synchronized. Two
threads can at the same time allocate a new row for evtchn_to_irq and
add the irq mapping to the their newly allocated row. One thread will
overwrite what the other has set for evtchn_to_irq[row] and therefore
the irq mapping is lost. This will trigger a BUG_ON later in

This patch sets evtchn_to_irq rows via a cmpxchg operation so that they
will be set only once. The row is now cleared before writing it to
evtchn_to_irq in order to not create a race once the row is visible for
other threads.
While at it, do not require the page to be zeroed, because it will be
overwritten with -1's in clear_evtchn_to_irq_row anyway.

Unfortunately we have been unable to find a reliable way to detect if
and how SW_TABLET_MODE reporting is supported, so we are relying on
DMI quirks for this.

be easily tested without needing to rebuild the kernel.

The SFC_DONE register lives within the corresponding VD0/VD2/VD4/VD6
forcewake domain and is not accessible if the vdbox in that domain is
fused off and the forcewake is not initialized.
This mistake went unnoticed because until recently we were using the
wrong register offset for the SFC_DONE register; once the register
offset was corrected, we started hitting errors like
<4> [544.989065] i915 0000:cc:00.0: Uninitialized forcewake domain(s) 0x80 accessed at 0x1ce000

Till DISPLAY12 the PIPE_MISC bits 5-7 are used to set the
Dithering BPC, with valid values of 6, 8, 10 BPC.
For ADLP+ these bits are used to set the PORT OUTPUT BPC, with valid
values of: 6, 8, 10, 12 BPC, and need to be programmed whether
dithering is enabled or not.
This patch:
-corrects the bits 5-7 for PIPE MISC register for 12 BPC.
-renames the bits and mask to have generic names for these bits for
dithering bpc and port output bpc.
v3: Added a note for MIPI DSI which uses the PIPE_MISC for readout
for pipe_bpp. (Uma Shankar)
v2: Added 'display' to the subject and fixes tag. (Uma Shankar)
