[PATCH 0/7] accel/ivpu: Add context violation handling for 6.12

by Jacek Lawrynowicz

These patchset adds support for VPU_JSM_STATUS_MVNCI_CONTEXT_VIOLATION_HW message added in recent VPU firmware. Without it the driver will not be able to process any jobs after this message is received and would need to be reloaded. Most patches are as-is from upstream besides these two: - Fix locking order in ivpu_job_submit - Abort all jobs after command queue unregister Both these patches need to be rebased because of missing new CMDQ UAPI changes that should not be backported to stable. Andrew Kreimer (1): accel/ivpu: Fix a typo Andrzej Kacprowski (1): accel/ivpu: Update VPU FW API headers Karol Wachowski (4): accel/ivpu: Use xa_alloc_cyclic() instead of custom function accel/ivpu: Abort all jobs after command queue unregister accel/ivpu: Fix locking order in ivpu_job_submit accel/ivpu: Add handling of VPU_JSM_STATUS_MVNCI_CONTEXT_VIOLATION_HW Tomasz Rusinowicz (1): accel/ivpu: Make DB_ID and JOB_ID allocations incremental drivers/accel/ivpu/ivpu_drv.c | 38 ++-- drivers/accel/ivpu/ivpu_drv.h | 9 + drivers/accel/ivpu/ivpu_job.c | 125 +++++++++--- drivers/accel/ivpu/ivpu_job.h | 1 + drivers/accel/ivpu/ivpu_jsm_msg.c | 3 +- drivers/accel/ivpu/ivpu_mmu.c | 3 +- drivers/accel/ivpu/ivpu_sysfs.c | 5 +- drivers/accel/ivpu/vpu_boot_api.h | 45 +++-- drivers/accel/ivpu/vpu_jsm_api.h | 303 +++++++++++++++++++++++++----- 9 files changed, 412 insertions(+), 120 deletions(-) -- 2.45.1

[PATCH] fs: minix: Fix handling of corrupted directories

by Andrey Kriulin

If the directory is corrupted and the number of nlinks is less than 2 (valid nlinks have at least 2), then when the directory is deleted, the minix_rmdir will try to reduce the nlinks(unsigned int) to a negative value.

[PATCH 0/3] can: rx-offload: fix order of unregistration calls

by Marc Kleine-Budde

If a driver is removed, the driver framework invokes the driver's remove callback. A CAN driver's remove function calls unregister_candev(), which calls net_device_ops::ndo_stop further down in the call stack for interfaces which are in the "up" state. With the mcp251xfd driver the removal of the module causes the following warning: | WARNING: CPU: 0 PID: 352 at net/core/dev.c:7342 __netif_napi_del_locked+0xc8/0xd8 as can_rx_offload_del() deletes the NAPI, while it is still active, because the interface is still up. To fix the warning, first unregister the network interface, which calls net_device_ops::ndo_stop, which disables the NAPI, and then call can_rx_offload_del(). All other driver using the rx-offload helper have been checked and the same issue has been found in the rockchip and m_can driver. These have been fixed, but only compile time tested. On the mcp251xfd the fix was tested on hardware.
