2024-04-17drm/i915/display: add support for DMC wakelocksLuca Coelho
In order to reduce the DC5->DC2 restore time, wakelocks have been introduced in DMC so the driver can tell it when registers and other memory areas are going to be accessed and keep their respective blocks awake. Implement this in the driver by adding the concept of DMC wakelocks. When the driver needs to access memory which lies inside pre-defined ranges, it will tell DMC to set the wakelock, access the memory, then wait for a while and clear the wakelock. The wakelock state is protected in the driver with spinlocks to prevent concurrency issues.

2024-04-16mm,page_owner: fix refcount imbalanceOscar Salvador
Current code does not contemplate scenarios were an allocation and free operation on the same pages do not handle it in the same amount at once. To give an example, page_alloc_exact(), where we will allocate a page of enough order to stafisfy the size request, but we will free the remainings right away. In the above example, we will increment the stack_record refcount only once, but we will decrease it the same number of times as number of unused pages we have to free. This will lead to a warning because of refcount imbalance. Fix this by recording the number of base pages in the refcount field.

This module displays a user friendly message when a kernel panic occurs. It currently doesn't contain any debug information, but that can be added later. v2 * Use get_scanout_buffer() instead of the drm client API. (Thomas Zimmermann) * Add the panic reason to the panic message (Nerdopolis) * Add an exclamation mark (Nerdopolis) v3 * Rework the drawing functions, to write the pixels line by line and to use the drm conversion helper to support other formats. (Thomas Zimmermann) v4 * Use drm_fb_r1_to_32bit for fonts (Thomas Zimmermann) * Remove the default y to DRM_PANIC config option (Thomas Zimmermann) * Add foreground/background color config option * Fix the bottom lines not painted if the framebuffer height is not a multiple of the font height. * Automatically register the device to drm_panic, if the function get_scanout_buffer exists. (Thomas Zimmermann) v5 * Change the drawing API, use drm_fb_blit_from_r1() to draw the font. * Also add drm_fb_fill() to fill area with background color. * Add draw_pixel_xy() API for drivers that can't provide a linear buffer. * Add a flush() callback for drivers that needs to synchronize the buffer. * Add a void *private field, so drivers can pass private data to draw_pixel_xy() and flush(). v6 * Fix sparse warning for panic_msg and logo. v7 * Add select DRM_KMS_HELPER for the color conversion functions. v8 * Register directly each plane to the panic notifier (Sima) * Add raw_spinlock to properly handle concurrency (Sima) * Register plane instead of device, to avoid looping through plane list, and simplify code. * Replace get_scanout_buffer() logic with drm_panic_set_buffer() (Thomas Zimmermann) * Removed the draw_pixel_xy() API, will see later if it can be added back. v9 * Revert to using get_scanout_buffer() (Sima) * Move get_scanout_buffer() and panic_flush() to the plane helper functions (Thomas Zimmermann) * Register all planes with get_scanout_buffer() to the panic notifier * Use drm_panic_lock() to protect against race (Sima) v10 * Move blit and fill functions back in drm_panic (Thomas Zimmermann). * Simplify the text drawing functions. * Use kmsg_dumper instead of panic_notifier (Sima). v12 * Use array for map and pitch in struct drm_scanout_buffer to support multi-planar format later.

Pull more bcachefs fixes from Kent Overstreet: "Notable user impacting bugs - On multi device filesystems, recovery was looping in btree_trans_too_many_iters(). This checks if a transaction has touched too many btree paths (because of iteration over many keys), and isuses a restart to drop unneeded paths. But it's now possible for some paths to exceed the previous limit without iteration in the interior btree update path, since the transaction commit will do alloc updates for every old and new btree node, and during journal replay we don't use the btree write buffer for locking reasons and thus those updates use btree paths when they wouldn't normally. - Fix a corner case in rebalance when moving extents on a durability=0 device. This wouldn't be hit when a device was formatted with durability=0 since in that case we'll only use it as a write through cache (only cached extents will live on it), but durability can now be changed on an existing device. - bch2_get_acl() could rarely forget to handle a transaction restart; this manifested as the occasional missing acl that came back after dropping caches. - Fix a major performance regression on high iops multithreaded write workloads (only since 6.9-rc1); a previous fix for a deadlock in the interior btree update path to check the journal watermark introduced a dependency on the state of btree write buffer flushing that we didn't want. - Assorted other repair paths and recovery fixes" * tag 'bcachefs-2024-04-10' of https://evilpiepirate.org/git/bcachefs: (25 commits) bcachefs: Fix __bch2_btree_and_journal_iter_init_node_iter() bcachefs: Kill read lock dropping in bch2_btree_node_lock_write_nofail() bcachefs: Fix a race in btree_update_nodes_written() bcachefs: btree_node_scan: Respect member.data_allowed bcachefs: Don't scan for btree nodes when we can reconstruct bcachefs: Fix check_topology() when using node scan bcachefs: fix eytzinger0_find_gt() bcachefs: fix bch2_get_acl() transaction restart handling bcachefs: fix the count of nr_freed_pcpu after changing bc->freed_nonpcpu list bcachefs: Fix gap buffer bug in bch2_journal_key_insert_take() bcachefs: Rename struct field swap to prevent macro naming collision MAINTAINERS: Add entry for bcachefs documentation Documentation: filesystems: Add bcachefs toctree bcachefs: JOURNAL_SPACE_LOW bcachefs: Disable errors=panic for BCH_IOCTL_FSCK_OFFLINE bcachefs: Fix BCH_IOCTL_FSCK_OFFLINE for encrypted filesystems bcachefs: fix rand_delete unit test bcachefs: fix ! vs ~ typo in __clear_bit_le64() bcachefs: Fix rebalance from durability=0 device bcachefs: Print shutdown journal sequence number ...

BHI mitigation mode spectre_bhi=auto does not deploy the software mitigation by default. In a cloud environment, it is a likely scenario where userspace is trusted but the guests are not trusted. Deploying system wide mitigation in such cases is not desirable. Update the auto mode to unconditionally mitigate against malicious guests. Deploy the software sequence at VMexit in auto mode also, when hardware mitigation is not available. Unlike the force =on mode, software sequence is not deployed at syscalls in auto mode.

Branch history clearing software sequences and hardware control BHI_DIS_S were defined to mitigate Branch History Injection (BHI). Add cmdline spectre_bhi={on|off|auto} to control BHI mitigation: auto - Deploy the hardware mitigation BHI_DIS_S, if available. on - Deploy the hardware mitigation BHI_DIS_S, if available, otherwise deploy the software sequence at syscall entry and VMexit. off - Turn off BHI mitigation.

The field is used by some other kernel parts for reference counting (try_module_get()), so it is expected that drivers will set it.

As of the first s390 pull request during the 6.9 merge window, commit 691632f0e869 ("Merge tag 's390-6.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux"), s390 can be built with LLVM=1 when using LLVM 18.1.0, which is the first version that has SystemZ support implemented in ld.lld and llvm-objcopy. Update the supported architectures table in the Kbuild LLVM documentation to note this explicitly to make it more discoverable by users and other developers. Additionally, this brings s390 in line with the rest of the architectures in the table, which all support LLVM=1.
