drm/i915/ttm: audit remaining bo->resource

In the near future TTM will have NULL bo->resource when the object is
initially created, plus after calling into pipeline-gutting. Try to
handle the remaining cases. In practice NULL bo->resource should be
taken to mean swapped-out or purged object.

v2 (Andrzej):
  - Rather make i915_ttm_cpu_maps_iomem() return false with NULL
    resource.

drm/panel: boe-tv101wum-nl6: Ensure DSI writes succeed during disable

The unprepare sequence has started to fail after moving to panel bridge
code in the msm drm driver (commit 007ac0262b0d ("drm/msm/dsi: switch to

   panel-boe-tv101wum-nl6 ae94000.dsi.0: failed to set panel off: -22

This is because boe_panel_enter_sleep_mode() needs an operating DSI link
to set the panel into sleep mode. Performing those writes in the
unprepare phase of bridge ops is too late, because the link has already
been torn down by the DSI controller in post_disable, i.e. the PHY has
been disabled, etc. See dsi_mgr_bridge_post_disable() for more details
on the DSI .

Split the unprepare function into a disable part and an unprepare part.
For now, just the DSI writes to enter sleep mode are put in the disable
function. This fixes the panel off routine and keeps the panel happy.

My Wormdingler has an integrated touchscreen that stops responding to
touch if the panel is only half disabled too. This patch fixes it. And
finally, this saves power when the screen is off because without this
fix the regulators for the panel are left enabled when nothing is being
displayed on the screen.

This tag contains habanalabs driver and accel changes for v6.3:

- Moved the driver to the accel subsystem. Currently only the files were
  moved (including the uapi file which was also renamed). This doesn't
  include registering to the accel subsystem. This will probably be only
  in the next kernel version.

- In case of decoder error (axi error) in Gaudi2, we can now find the exact
  IP that initiated the erroneous transaction and print the details for
  better debug.

- Add more trace events. We now can trace mmio transactions and communication
  with the preboot firmware.

- Add to Gaudi2 support for abrupt reset that is done by the firmware. This
  was support so far only for Gaudi1.

- Add uAPI to flush memory transactions (to the device memory). This is
  needed by the communications library in case of doing p2p with a host NIC
  which access our HBM directly through the PCI BAR.

- Add uAPI to pass-through a request from user-space to firmware and get the
  result back to user-space. This will allow the driver code to avoid the
  need to add new packet (in the communication channel with the firmware) for
  every new request type.

- Remove the option to export dma-buf by memory allocation handle in our uAPI.
  This was planned for Gaudi2 but was never used. Instead, we will do export
  by memory address (same as Gaudi1). In addition, we added the option to
  specify an offset to the address. This is needed in Gaudi2 because there
  the user allocates the entire HBM in one allocation, but would like to
  export only small part of it.

- Multiple bug fixes, refactors and small optimizations.

Revert "mm/compaction: fix set skip in fast_find_migrateblock"

This reverts commit 7efc3b7261030da79001c00d92bc3392fd6c664c.

We have got openSUSE reports (Link 1) for 6.1 kernel with khugepaged
stalling CPU for long periods of time.  Investigation of tracepoint data
shows that compaction is stuck in repeating fast_find_migrateblock()
based migrate page isolation, and then fails to migrate all isolated
pages.

Commit 7efc3b726103 ("mm/compaction: fix set skip in fast_find_migrateblock")
was suspected as it was merged in 6.1 and in theory can indeed remove a
termination condition for fast_find_migrateblock() under certain
conditions, as it removes a place that always marks a scanned pageblock
from being re-scanned.  There are other such places, but those can be
skipped under certain conditions, which seems to match the tracepoint
data.

Testing of revert also appears to have resolved the issue, thus revert
the commit until a more robust solution for the original problem is
developed.

It's also likely this will fix qemu stalls with 6.1 kernel reported in
Link 2, but that is not yet confirmed.

ovl: fail on invalid uid/gid mapping at copy up

If st_uid/st_gid doesn't have a mapping in the mounter's user_ns, then
copy-up should fail, just like it would fail if the mounter task was doing
the copy using "cp -a".

There's a corner case where the "cp -a" would succeed but copy up fail: if
there's a mapping of the invalid uid/gid (65534 by default) in the user
namespace.  This is because stat(2) will return this value if the mapping
doesn't exist in the current user_ns and "cp -a" will in turn be able to
create a file with this uid/gid.

This behavior would be inconsistent with POSIX ACL's, which return -1 for
invalid uid/gid which result in a failed copy.

For consistency and simplicity fail the copy of the st_uid/st_gid are

Dylan Yudaken [Fri, 27 Jan 2023 10:59:11 +0000 (02:59 -0800)]
io_uring: always prep_async for drain requests

Drain requests all go through io_drain_req, which has a quick exit in case
there is nothing pending (ie the drain is not useful). In that case it can
run the issue the request immediately.

However for safety it queues it through task work.
The problem is that in this case the request is run asynchronously, but
the async work has not been prepared through io_req_prep_async.

This has not been a problem up to now, as the task work always would run
before returning to userspace, and so the user would not have a chance to
race with it.

However - with IORING_SETUP_DEFER_TASKRUN - this is no longer the case and
the work might be defered, giving userspace a chance to change data being
referred to in the request.

Instead _always_ prep_async for drain requests, which is simpler anyway
and removes this issue.

17 months agotools: gpio: fix -c option of gpio-event-mon
Ivo Borisov Shopov [Thu, 26 Jan 2023 13:10:33 +0000 (15:10 +0200)]
tools: gpio: fix -c option of gpio-event-mon

Following line should listen for a rising edge and exit after the first
one since '-c 1' is provided.

    # gpio-event-mon -n gpiochip1 -o 0 -r -c 1

It works with kernel 4.19 but it doesn't work with 5.10. In 5.10 the
above command doesn't exit after the first rising edge it keep listening
for an event forever. The '-c 1' is not taken into an account.
The problem is in commit 62757c32d5db ("tools: gpio: add multi-line
monitoring to gpio-event-mon").
Before this commit the iterator 'i' in monitor_device() is used for
counting of the events (loops). In the case of the above command (-c 1)
we should start from 0 and increment 'i' only ones and hit the 'break'
statement and exit the process. But after the above commit counting
doesn't start from 0, it start from 1 when we listen on one line.
It is because 'i' is used from one more purpose, counting of lines
(num_lines) and it isn't restore to 0 after following code

    for (i = 0; i < num_lines; i++)
        gpiotools_set_bit(&values.mask, i);

Restore the initial value of the iterator to 0 in order to allow counting
of loops to work for any cases.

impression is that these are not actually needed at all if the driver generally

to make the driver build in all configurations.

treewide: fix up files incorrectly marked executable

I'm not exactly clear on what strange workflow causes people to do it,
but clearly occasionally some files end up being committed as executable
even though they clearly aren't.

This is a reprise of commit 90fda63fa115 ("treewide: fix up files
incorrectly marked executable"), just with a different set of files (but
with the same trivial shell scripting).

So apparently we need to re-do this every five years or so, and Joe
needs to just keep reminding me to do so ;)

17 months agodrm/tegra: Remove #ifdef guards for PM related functions

drm/tegra: Remove #ifdef guards for PM related functions

Use the RUNTIME_PM_OPS() and pm_ptr() macros to handle the
.runtime_suspend/.runtime_resume callbacks.

These macros allow the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_PM is disabled, without having
to use #ifdef guards.

This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.

gpu: host1x: External timeout/cancellation for fences

Currently all fences have a 30 second timeout to ensure they are
cleaned up if the fence never completes otherwise. However, this
one size fits all solution doesn't actually fit in every case,
such as syncpoint waiting where we want to be able to have timeouts
longer than 30 seconds. As such, we want to be able to give control
over fence cancellation to the caller (and maybe eventually get rid
of the internal timeout altogether).

Here we add this cancellation mechanism by essentially adding a
function for entering the timeout path by function call, and changing
the syncpoint wait function to use it.
