2023-10-09ACPI: resource: Add TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q to ↵Hans de Goede
irq1_edge_low_force_override[] The TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q are 3 GPU variants of a TongFang barebone design which is sold under various brand names. The ACPI IRQ override for the keyboard IRQ must be used on these AMD Zen laptops in order for the IRQ to work. Adjust the pcspecialist_laptop[] DMI match table for this: 1. Drop the sys-vendor match from the existing PCSpecialist Elimina Pro 16 entry for the GM6BGEQ (RTX3050 GPU) model so that it will also match the laptop when sold by other vendors such as hyperbook.pl. 2. Add board-name matches for the GM6BG5Q (RTX4050) and GM6B0Q (RTX4060) models. Note the .ident values of the dmi_system_id structs are left unset since these are not used.

2023-10-09ASoC: codecs: wsa-macro: fix uninitialized stack variables with name prefixKrzysztof Kozlowski
Driver compares widget name in wsa_macro_spk_boost_event() widget event callback, however it does not handle component's name prefix. This leads to using uninitialized stack variables as registers and register values. Handle gracefully such case.

2023-10-09ASoC: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-10-09printk: flush consoles before checking progressJohn Ogness
Commit 9e70a5e109a4 ("printk: Add per-console suspended state") removed console lock usage during resume and replaced it with the clearly defined console_list_lock and srcu mechanisms. However, the console lock usage had an important side-effect of flushing the consoles. After its removal, consoles were no longer flushed before checking their progress. Add the console_lock/console_unlock dance to the beginning of __pr_flush() to actually flush the consoles before checking their progress. Also add comments to clarify this additional usage of the console lock. Note that console_unlock() does not guarantee flushing all messages since the commit dbdda842fe96f89 ("printk: Add console owner and waiter logic to load balance console writes").

2023-10-09sched/eevdf: Fix pick_eevdf()Benjamin Segall
The old pick_eevdf() could fail to find the actual earliest eligible deadline when it descended to the right looking for min_deadline, but it turned out that that min_deadline wasn't actually eligible. In that case we need to go back and search through any left branches we skipped looking for the actual best _eligible_ min_deadline. This is more expensive, but still O(log n), and at worst should only involve descending two branches of the rbtree. I've run this through a userspace stress test (thank you tools/lib/rbtree.c), so hopefully this implementation doesn't miss any corner cases.

2023-10-09xen/events: replace evtchn_rwlock with RCUJuergen Gross
In unprivileged Xen guests event handling can cause a deadlock with Xen console handling. The evtchn_rwlock and the hvc_lock are taken in opposite sequence in __hvc_poll() and in Xen console IRQ handling. Normally this is no problem, as the evtchn_rwlock is taken as a reader in both paths, but as soon as an event channel is being closed, the lock will be taken as a writer, which will cause read_lock() to block: CPU0 CPU1 CPU2 (IRQ handling) (__hvc_poll()) (closing event channel) read_lock(evtchn_rwlock) spin_lock(hvc_lock) write_lock(evtchn_rwlock) [blocks] spin_lock(hvc_lock) [blocks] read_lock(evtchn_rwlock) [blocks due to writer waiting, and not in_interrupt()] This issue can be avoided by replacing evtchn_rwlock with RCU in xen_free_irq(). Note that RCU is used only to delay freeing of the irq_info memory. There is no RCU based dereferencing or replacement of pointers involved. In order to avoid potential races between removing the irq_info reference and handling of interrupts, set the irq_info pointer to NULL only when freeing its memory. The IRQ itself must be freed at that time, too, as otherwise the same IRQ number could be allocated again before handling of the old instance would have been finished. This is XSA-441 / CVE-2023-34324.

2023-10-09dmaengine: stm32-dma: fix residue in case of MDMA chainingAmelie Delaunay
In case of MDMA chaining, DMA is configured in Double-Buffer Mode (DBM) with two periods, but if transfer has been prepared with _prep_slave_sg(), the transfer is not marked cyclic (=!chan->desc->cyclic). However, as DBM is activated for MDMA chaining, residue computation must take into account cyclic constraints. With only two periods in MDMA chaining, and no update due to Transfer Complete interrupt masked, n_sg is always 0. If DMA current memory address (depending on SxCR.CT and SxM0AR/SxM1AR) does not correspond, it means n_sg should be increased. Then, the residue of the current period is the one read from SxNDTR and should not be overwritten with the full period length.

2023-10-09dmaengine: stm32-mdma: set in_flight_bytes in case CRQA flag is setAmelie Delaunay
CRQA flag is set by hardware when the channel request become active and the channel is enabled. It is cleared by hardware, when the channel request is completed. So when it is set, it means MDMA is transferring bytes. This information is useful in case of STM32 DMA and MDMA chaining, especially when the user pauses DMA before stopping it, to trig one last MDMA transfer to get the latest bytes of the SRAM buffer to the destination buffer. STM32 DCMI driver can then use this to know if the last MDMA transfer in case of chaining is done.

2023-10-09dmaengine: stm32-mdma: use Link Address Register to compute residueAmelie Delaunay
Current implementation relies on curr_hwdesc index. But to keep this index up to date, Block Transfer interrupt (BTIE) has to be enabled. If it is not, curr_hwdesc is not updated, and then residue is not reliable. Rely on Link Address Register instead. And disable BTIE interrupt in stm32_mdma_setup_xfer() because it is no more needed in case of _prep_slave_sg() to maintain curr_hwdesc up to date. It avoids extra interrupts and also ensures a reliable residue. These improvements are required for STM32 DCMI camera capture use case, which need STM32 DMA and MDMA chaining for good performance.

When one of the LAG interfaces is in switchdev mode, setting default rule can't be done. The interface on which switchdev is running has ice_set_rx_mode() blocked to avoid default rule adding (and other rules). The other interfaces (without switchdev running but connected via bond with interface that runs switchdev) can't follow the same scheme, because rx filtering needs to be disabled when failover happens. Notification for bridge to set promisc mode seems like good place to do that.

Do not set netback interfaces (vifs) default TX queue size to the ring size. The TX queue size is not related to the ring size, and using the ring size (32) as the queue size can lead to packet drops. Note the TX side of the vif interface in the netback domain is the one receiving packets to be injected to the guest. Do not explicitly set the TX queue length to any value when creating the interface, and instead use the system default. Note that the queue length can also be adjusted at runtime.
