2022-09-13drm/amd/display: SW cursor fallback for SubVPAlvin Lee4-0/+8
[Description] Leverage SW cursor fall back for SubVP when the cursor is too big. We want to take advantage of being able to fallback to SW cursor when possible because it's not worth it to disable MCLK switching because the cursor is slightly too big.

2022-09-13drm/amd/display: Round cursor width up for MALL allocationTaimur Hassan2-2/+46
[Why & How] When calculating cursor size for MALL allocation, the cursor width should be the actual width rounded up to 64 alignment. Additionally, the bit depth should vary depending on color format.

[Why & How] Add support for the DML314 functions and hook up DCN314 to use them. This has some necessary additions for calculating Max VSTARTUP for future features, but there's also some changes that we have to make for pixel format/swizzle support.

2022-09-13Revert "fs/exec: allow to unshare a time namespace on vfork+exec"Andrei Vagin3-13/+2
This reverts commit 133e2d3e81de5d9706cab2dd1d52d231c27382e5. Alexey pointed out a few undesirable side effects of the reverted change. First, it doesn't take into account that CLONE_VFORK can be used with CLONE_THREAD. Second, a child process doesn't enter a target time name-space, if its parent dies before the child calls exec. It happens because the parent clears vfork_done. Eric W. Biederman suggests installing a time namespace as a task gets a new mm. It includes all new processes cloned without CLONE_VM and all tasks that call exec(). This is an user API change, but we think there aren't users that depend on the old behavior. It is too late to make such changes in this release, so let's roll back this patch and introduce the right one in the next release.

2022-09-13btrfs: zoned: wait for extent buffer IOs before finishing a zoneNaohiro Aota1-2/+38
Before sending REQ_OP_ZONE_FINISH to a zone, we need to ensure that ongoing IOs already finished. Or, we will see a "Zone Is Full" error for the IOs, as the ZONE_FINISH command makes the zone full. We ensure that with btrfs_wait_block_group_reservations() and btrfs_wait_ordered_roots() for a data block group. And, for a metadata block group, the comparison of alloc_offset vs meta_write_pointer mostly ensures IOs for the allocated region already sent. However, there still can be a little time frame where the IOs are sent but not yet completed. Introduce wait_eb_writebacks() to ensure such IOs are completed for a metadata block group. It walks the buffer_radix to find extent buffers in the block group and calls wait_on_extent_buffer_writeback() on them.

We try to create an inline extent for them, but we fail when trying to insert the inline extent with -ENOSPC (at cow_file_range_inline()) - since this is not critical, we fallback to non-inline mode (back to cow_file_range()), reserve extents, create extent maps and create the ordered extents; 3) An unmount starts, enters close_ctree(); 4) The async reclaim task is flushing stuff, entering the flush states one by one, until it reaches RUN_DELAYED_IPUTS. There it runs all current delayed iputs. After running the delayed iputs and before calling btrfs_wait_on_delayed_iputs(), one or more ordered extents complete, and btrfs_add_delayed_iput() is called for each one through btrfs_finish_ordered_io() -> btrfs_put_ordered_extent(). This results in bumping fs_info->nr_delayed_iputs from 0 to some positive value. So the async reclaim task blocks at btrfs_wait_on_delayed_iputs() waiting for fs_info->nr_delayed_iputs to become 0; 5) The current transaction is committed by the transaction kthread, we then start unpinning extents and end up calling btrfs_try_granting_tickets() through unpin_extent_range(), since we released some space. This results in satisfying the ticket created by the cleaner kthread at step 1, waking up the cleaner kthread; 6) At close_ctree() we ask the cleaner kthread to park; 7) The cleaner kthread starts the transaction, deletes the unused block group, and then calls kthread_should_park(), which returns true, so it parks. And at this point we have the delayed iputs added by the completion of the ordered extents still pending; 8) Then later at close_ctree(), when we call: cancel_work_sync(&fs_info->async_reclaim_work); We hang forever, since the cleaner was parked and no one else can run delayed iputs after that, while the reclaim task is waiting for the remaining delayed iputs to be completed. Fix this by waiting for all ordered extents to complete and running the delayed iputs before attempting to stop the async reclaim tasks. Note that we can not wait for ordered extents with btrfs_wait_ordered_roots() (or other similar functions) because that waits for the BTRFS_ORDERED_COMPLETE flag to be set on an ordered extent, but the delayed iput is added after that, when doing the final btrfs_put_ordered_extent(). So instead wait for the work queues used for executing ordered extent completion to be empty, which works because we do the final put on an ordered extent at btrfs_finish_ordered_io() (while we are in the unmount context).

2022-09-13btrfs: fix hang during unmount when stopping block group reclaim workerFilipe Manana1-6/+11
During early unmount, at close_ctree(), we try to stop the block group reclaim task with cancel_work_sync(), but that may hang if the block group reclaim task is currently at btrfs_relocate_block_group() waiting for the flag BTRFS_FS_UNFINISHED_DROPS to be cleared from fs_info->flags. During unmount we only clear that flag later, after trying to stop the block group reclaim task. Fix that by clearing BTRFS_FS_UNFINISHED_DROPS before trying to stop the block group reclaim task and after setting BTRFS_FS_CLOSING_START, so that if the reclaim task is waiting on that bit, it will stop immediately after being woken, because it sees the filesystem is closing (with a call to btrfs_fs_closing()), and then returns immediately with -EINTR.

2022-09-13RISC-V: Clean up the Zicbom block size probingPalmer Dabbelt4-11/+16
This fixes two issues: I truncated the warning's hart ID when porting to the 64-bit hart ID code, and the original code's warning handling could fire on an uninitialized hart ID. The biggest change here is that riscv_cbom_block_size is no longer initialized, as IMO the default isn't sane: there's nothing in the ISA that mandates any specific cache block size, so falling back to one will just silently produce the wrong answer on some systems. This also changes the probing order so the cache block size is known before enabling Zicbom support.

The Aquantia datasheet notes that after issuing a Processor-Intensive MDIO operation, like changing the low-power state of the device, the driver should wait for the operation to finish before issuing a new MDIO command. The new aqr107_wait_processor_intensive_op() function is added which can be used after these kind of MDIO operations. At the moment, we are only adding it at the end of the suspend/resume calls. The issue was identified on a board featuring the AQR113C PHY, on which commands like 'ip link (..) up / down' issued without any delays between them would render the link on the PHY to remain down. The issue was easy to reproduce with a one-liner: $ ip link set dev ethX down; ip link set dev ethX up; \ ip link set dev ethX down; ip link set dev ethX up; Fixes: ac9e81c230eb ("net: phy: aquantia: add suspend / resume callbacks for AQR107 family") Signed-off-by: Ioana Ciornei <[email protected]> Reviewed-by: Andrew Lunn <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Paolo Abeni <[email protected]>
