20 months agodrm/vmwgfx: Rename vmw_buffer_object to vmw_bo

drm/vmwgfx: Rename vmw_buffer_object to vmw_bo

The rest of the drivers which are using ttm have mostly standardized on
driver_prefix_bo as the name for subclasses of the TTM buffer object.
Make vmwgfx match the rest of the drivers and follow the same naming
semantics.

This is especially clear given that the name of the file in which the
object was defined is vmw_bo.c.

drm/rockchip: vop2: initialize possible_crtcs properly

The variable possible_crtcs is only initialized for primary and
overlay planes. Since the VOP2 driver only supports these plane
types at the moment, the current code is safe. However, in order
to provide a future-proof solution, fix the initialization of
the variable.

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
DRM_PANEL_BRIDGE")). You'll see messages like this in the kernel logs:

   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.

Merge tag 'drm-habanalabs-next-2023-01-26' of https://git./linux/kernel/git/ogabbay/linux into drm-next

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.

Vlastimil Babka [Fri, 13 Jan 2023 17:33:45 +0000 (18:33 +0100)]
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.

Joe found another DT file that shouldn't be executable, and that

    git ls-files -s |
        grep '^100755' |

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
invalid.

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.

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.
