2024-12-10drm/log: Do not draw if drm_master is takenJocelyn Falempe
When userspace takes drm_master, the drm_client buffer is no more visible, so drm_log shouldn't waste CPU cycle to draw on it.

2024-12-10drm/log: Introduce a new boot logger to draw the kmsg on the screenJocelyn Falempe
drm_log is a simple logger that uses the drm_client API to print the kmsg boot log on the screen. This is not a full replacement to fbcon, as it will only print the kmsg. It will never handle user input, or a terminal because this is better done in userspace. Design decisions: * It uses the drm_client API, so it should work on all drm drivers from the start. * It doesn't scroll the message, that way it doesn't need to redraw the whole screen for each new message. It also means it doesn't have to keep drawn messages in memory, to redraw them when scrolling. * It uses the new non-blocking console API, so it should work well with PREEMPT_RT. This patch also adds a Kconfig menu to select the drm client to use. It can be overwritten on the kernel command line with: drm_client_lib.active=log or drm_client_lib.active=fbdev Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com> Reviewed-by: John Ogness <john.ogness@linutronix.de> # console API Reviewed-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20241204160014.1171469-3-jfalempe@redhat.com

2024-12-10openrisc: place exception table at the head of vmlinuxMasahiro Yamada
Since commit 0043ecea2399 ("vmlinux.lds.h: Adjust symbol ordering in text output section"), the exception table in arch/openrisc/kernel/head.S is no longer positioned at the very beginning of the kernel image, which causes a boot failure. Currently, the exception table resides in the regular .text section. Previously, it was placed at the head by relying on the linker receiving arch/openrisc/kernel/head.o as the first object. However, this behavior has changed because sections like .text.{asan,unknown,unlikely,hot} now precede the regular .text section. The .head.text section is intended for entry points requiring special placement. However, in OpenRISC, this section has been misused: instead of the entry points, it contains boot code meant to be discarded after booting. This feature is typically handled by the .init.text section. This commit addresses the issue by replacing the current __HEAD marker with __INIT and re-annotating the entry points with __HEAD. Additionally, it adds __REF to entry.S to suppress the following modpost warning: WARNING: modpost: vmlinux: section mismatch in reference: _tng_kernel_start+0x70 (section: .text) -> _start (section: .init.text) Fixes: 0043ecea2399 ("vmlinux.lds.h: Adjust symbol ordering in text output section") Reported-by: Guenter Roeck <linux@roeck-us.net> Closes: https://lore.kernel.org/all/5e032233-5b65-4ad5-ac50-d2eb6c00171c@roeck-us.net/#t Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Tested-by: Guenter Roeck <linux@roeck-us.net> Reviewed-by: Rong Xu <xur@google.com> Signed-off-by: Stafford Horne <shorne@gmail.com>
2024-12-10ALSA: control: Avoid WARN() for symlink errorsTakashi Iwai
Using WARN() for showing the error of symlink creations don't give more information than telling that something goes wrong, since the usual code path is a lregister callback from each control element creation. More badly, the use of WARN() rather confuses fuzzer as if it were serious issues. This patch downgrades the warning messages to use the normal dev_err() instead of WARN(). For making it clearer, add the function name to the prefix, too.

Koichiro Den says: ==================== virtio_net: correct netdev_tx_reset_queue() invocation points When virtnet_close is followed by virtnet_open, some TX completions can possibly remain unconsumed, until they are finally processed during the first NAPI poll after the netdev_tx_reset_queue(), resulting in a crash [1]. Commit b96ed2c97c79 ("virtio_net: move netdev_tx_reset_queue() call before RX napi enable") was not sufficient to eliminate all BQL crash scenarios for virtio-net. This issue can be reproduced with the latest net-next master by running: `while :; do ip l set DEV down; ip l set DEV up; done` under heavy network TX load from inside the machine. This patch series resolves the issue and also addresses similar existing problems: (a). Drop netdev_tx_reset_queue() from open/close path. This eliminates the BQL crashes due to the problematic open/close path. (b). As a result of (a), netdev_tx_reset_queue() is now explicitly required in freeze/restore path. Add netdev_tx_reset_queue() immediately after free_unused_bufs() invocation. (c). Fix missing resetting in virtnet_tx_resize(). virtnet_tx_resize() has lacked proper resetting since commit c8bd1f7f3e61 ("virtio_net: add support for Byte Queue Limits"). (d). Fix missing resetting in the XDP_SETUP_XSK_POOL path. Similar to (c), this path lacked proper resetting. Call netdev_tx_reset_queue() when virtqueue_reset() has actually recycled unused buffers. This patch series consists of six commits: [1/6]: Resolves (a) and (b). # also -stable 6.11.y [2/6]: Minor fix to make [4/6] streamlined.

For stall detector added to BQL, even if virtnet_close could somehow lead to some TX completions delayed for long, followed by virtnet_open, we can just take it as stall as mentioned in commit 6025b9135f7a ("net: dqs: add NIC stall detector based on BQL"). Note also that users can still reset stall_max via sysfs. So, drop netdev_tx_reset_queue() from virtnet_enable_queue_pair(). This eliminates the BQL crashes. As a result, netdev_tx_reset_queue() is now explicitly required in freeze/restore path. This patch adds it to immediately after free_unused_bufs(), following the rule of thumb: netdev_tx_reset_queue() should follow any SKB freeing not followed by netdev_tx_completed_queue(). This seems the most consistent and streamlined approach, and now netdev_tx_reset_queue() runs whenever free_unused_bufs() is done.

Large kmalloc directly allocates from the page allocator and then use lruvec_stat_mod_folio() to increment the unreclaimable slab stats for global and memcg. However when post memcg charging of slab objects was added in commit 9028cdeb38e1 ("memcg: add charging of already allocated slab objects"), it missed to correctly handle the unreclaimable slab stats for memcg. One user visisble effect of that bug is that the node level unreclaimable slab stat will work correctly but the memcg level stat can underflow as kernel correctly handles the free path but the charge path missed to increment the memcg level unreclaimable slab stat. Let's fix by correctly handle in the post charge code path.

Fix this issue by storing it in max_speed_hz of the relevant SPI device. This fix keeps the priority of the speed parameter (module parameter, device tree property, driver default).

2024-12-10power: supply: cros_charge-control: hide start threshold on v2 cmdThomas Weißschuh
ECs implementing the v2 command will not stop charging when the end threshold is reached. Instead they will begin discharging until the start threshold is reached, leading to permanent charge and discharge cycles. This defeats the point of the charge control mechanism. Avoid the issue by hiding the start threshold on v2 systems. Instead on those systems program the EC with start == end which forces the EC to reach and stay at that level. v1 does not support thresholds and v3 works correctly, at least judging from the code.

2024-12-10power: supply: gpio-charger: Fix set charge current limitsDimitri Fedrau
Fix set charge current limits for devices which allow to set the lowest charge current limit to be greater zero. If requested charge current limit is below lowest limit, the index equals current_limit_map_size which leads to accessing memory beyond allocated memory.

Introduce it6263_is_input_bus_fmt_valid() and refactor the it6263_bridge_atomic_get_input_bus_fmts() function to support VESA-24 format by selecting the LVDS input format based on the LVDS data mapping and thereby support both JEIDA-24 and VESA-24 input formats.
