2024-05-07virtio_net: Remove command data from control_bufDaniel Jurgens
Allocate memory for the data when it's used. Ideally the struct could be on the stack, but we can't DMA stack memory. With this change only the header and status memory are shared between commands, which will allow using a tighter lock than RTNL.

2024-05-07net: dsa: mt7530: detect PHY muxing when PHY is defined on switch MDIO busArınç ÜNAL
Currently, the MT7530 DSA subdriver configures the MT7530 switch to provide direct access to switch PHYs, meaning, the switch PHYs listen on the MDIO bus the switch listens on. The PHY muxing feature makes use of this. This is problematic as the PHY may be attached before the switch is initialised, in which case, the PHY will fail to be attached. Since commit 91374ba537bd ("net: dsa: mt7530: support OF-based registration of switch MDIO bus"), we can describe the switch PHYs on the MDIO bus of the switch on the device tree. Extend the check to detect PHY muxing when the PHY is defined on the MDIO bus of the switch on the device tree. When the PHY is described this way, the switch will be initialised first, then the switch MDIO bus will be registered. Only after these steps, the PHY will be attached.

The other thing here is the removal of most of the SOC_VENDOR options, with their ARCH_VENDOR equivalents that've been waiting in the wings for 1 year+ now made visible.

Currently the documentation for line names allows to use %u inside the alternative name. This is broken in character device approach from day 1 and being in use solely in sysfs. Character device interface has a line number as a part of its address, so the users better rely on it. Hence remove the misleading documentation. On top of that, there are no in-kernel users (out of 6, if I'm correct) for such names and moreover if one exists it won't help in distinguishing lines with the same naming as '%u' will also be in them and we will get a warning in gpiochip_set_desc_names() for such cases.

This patch takes the approach of treating such a situation as an error which it detects by making use of the return value of snprintf, which is the total number of bytes, excluding the trailing '\0', that would have been written. Based on the approach taken to a similar problem in commit 54b909436ede ("rtc: fix snprintf() checking in is_rtc_hctosys()") Flagged by gcc-13 W=1 builds as: .../otx2_pf.c:1933:58: warning: 'snprintf' output may be truncated before the last format character [-Wformat-truncation=] 1933 | snprintf(irq_name, NAME_SIZE, "%s-rxtx-%d", pf->netdev->name, | ^ .../otx2_pf.c:1933:17: note: 'snprintf' output between 8 and 33 bytes into a destination of size 32 1933 | snprintf(irq_name, NAME_SIZE, "%s-rxtx-%d", pf->netdev->name, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1934 | qidx); | ~~~~~ Compile tested only.

The driver's I/O path is updated to support 32 byte CDBs.

2024-05-06scsi: lpfc: Clear deferred RSCN processing flag when driver is unloadingJustin Tee
Device recovery logic is skipped when the RSCN processing flag is set. However during rmmod, the flag is not cleared leading to unnecessary delays in waiting for completions on a link that is being offlined. Move clearing of the RSCN deferred flag to a refactored routine when called from device recovery, and set the IA flag when issuing an abort during unload.

2024-05-06Merge patch series "ufs-exynos support for Tensor GS101"Martin K. Petersen
Peter Griffin <peter.griffin@linaro.org> says: Hi Martin, James & Alim, This series adds support to the ufs-exynos driver for Tensor gs101 found in Pixel 6. It was send previously in [1] and [2] but included the other clock, phy and DTS parts. This series has been split into just the ufs-exynos part to hopefully make things easier. With this series, plus the phy, clock and dts changes UFS is functional upstream for Pixel 6. The SKhynix HN8T05BZGKX015 can be enumerated, partitions mounted etc. The series is split into some prepatory patches for ufs-exynos and a final patch that adds the gs101 support. Note the sysreg clock has been moved to ufs node as fine grained clock control around the syscon sysreg register accesses doesn't result in functional UFS. regards, Peter Link: https://lore.kernel.org/r/20240426122004.2249178-1-peter.griffin@linaro.org Signed-off-by: Martin K.

2024-05-06scsi: ufs: exynos: Add support for Tensor gs101 SoCPeter Griffin
Add a dedicated compatible and drv_data with associated hooks for gs101 SoC found on Pixel 6. Note we make use of the previously added EXYNOS_UFS_OPT_UFSPR_SECURE option, to skip initialisation of UFSPR registers as these are only accessible via SMC call. EXYNOS_UFS_OPT_TIMER_TICK_SELECT option is also set to select tick source. This has been done so as not to effect any existing platforms. DBG_OPTION_SUITE on gs101 has different address offsets to other SoCs so these register offsets now come from uic_attr struct.
