Main motivation was to fix errors reported by NetworkManager while enabling WiFi hotspot - but also added more options after consulting Debian's kernel config, which has them enabled.

The default behavior on kernel panic is to hang indefinitely, which isn't great for a battery powered device where investigating a panic after it happened may not even be feasible. Therefore, set up the kernel so it reboots on panic. For debugging, this can be disabled at runtime by calling `sysctl kernel.panic=0`. A delay before rebooting can be set by replacing `0` with a number of seconds.

commit bd7ffbc3 upstream. When locking a region, we currently clamp to a PAGE_SIZE as the minimum lock region. While this is valid for Midgard, it is invalid for Bifrost, where the minimum locking size is 8x larger than the 4k page size. Add a hardware definition for the minimum lock region size (corresponding to KBASE_LOCK_REGION_MIN_SIZE_LOG2 in kbase) and respect it. Signed-off-by:

commit a77b5882 upstream. Mali virtual addresses are 48-bit. Use a u64 instead of size_t to ensure we can express the "lock everything" condition as ~0ULL without overflow. This code was silently broken on any platform where a size_t is less than 48-bits; in particular, it was broken on 32-bit armv7 platforms which remain in use with panfrost.

commit b5fab345 upstream. In lock_region, simplify the calculation of the region_width parameter. This field is the size, but encoded as ceil(log2(size)) - 1. ceil(log2(size)) may be computed directly as fls(size - 1). However, we want to use the 64-bit versions as the amount to lock can exceed 32-bits. This avoids undefined (and completely wrong) behaviour when locking all memory (size ~0). In this case, the old code would "round up" ~0 to the nearest page, overflowing to 0. Since fls(0) == 0, this would calculate a region width of 10 + 0 = 10. But then the code would shift by (region_width - 11) = -1. As shifting by a negative number is undefined, UBSAN flags the bug. Of course, even if it were defined the behaviour is wrong, instead of locking all memory almost none would get locked. The new form of the calculation corrects this special case and avoids the undefined behaviour. Signed-off-by:

commit 5bccb945 upstream. Add safe lut configuration for all the targets in dpu driver as per QOS recommendation. Issue reported on SC7280: With wait-for-safe feature in smmu enabled, RT client buffer levels are checked to be safe before smmu invalidation. Since display was always set to unsafe it was delaying the invalidaiton process thus impacting the performance on NRT clients such as eMMC and NVMe. Validated this change on SC7280, With this change eMMC performance has improved significantly. Changes in v2: - Add fixes tag (Sai) - CC stable kernel (Dimtry) Changes in v3: - Correct fixes tag with appropriate hash (stephen) - Resend patch adding reviewed by tag - Resend patch adding correct format for pushing into stable tree (Greg) Fixes: 591e34a0 ("drm/msm/disp/dpu1: add support for display for SC7280 target") Cc: stable@vger.kernel.org Signed-off-by:

commit 7fdc48cc upstream. Jobs can be in-flight when the file descriptor is closed (either because the process did not terminate properly, or because it didn't wait for all GPU jobs to be finished), and apparently panfrost_job_close() does not cancel already running jobs. Let's refcount the MMU context object so it's lifetime is no longer bound to the FD lifetime and running jobs can finish properly without generating spurious page faults. Reported-by:

commit 92bd92c4 upstream. Commit 2f015ec6 ("drm/dp_mst: Add sideband down request tracing + selftests") added some debug code for sideband message tracing. But it seems to have unintentionally changed the behavior on sideband message failure. It catches and returns failure only if DRM_UT_DP is enabled. Otherwise it ignores the error code and returns success. So on an MST unplug, the caller is unaware that the clear payload message failed and ends up waiting for 4 seconds for the response. Fixes the issue by returning the proper error code.

commit 14769672 upstream. Put the clock-selection code into each of the PLL-update functions to make them select the correct pixel clock. Instead of copying the code, introduce a new helper WREG_MISC_MASKED, which does masked writes into <MISC>. Use it from each individual PLL update function. The pixel clock for video output was not actually set before programming the clock's values. It worked because the device had the correct clock pre-set. v2: * don't duplicate <MISC> update code (Sam) Signed-off-by:

commit 81d0885d upstream. tx_done is not used for napi_complete_done(). Thus, NAPI busy polling mechanism by gro_flush_timeout and napi_defer_hard_irqs will not able be triggered after a packet is transmitted when there is no receive packet. Fix this by taking the maximum value between tx_done and rx_done as overall budget completed by the rxtx NAPI poll to ensure XDP Tx ZC operation is continuously polling for next Tx frame. This gives benefit of lower packet submission processing latency and jitter under XDP Tx ZC mode. Performance of tx-only using xdp-sock on Intel ADL-S platform is the same with and without this patch. root@intel-corei7-64:~# ./xdpsock -i enp0s30f4 -t -z -q 1 -n 10 sock0@enp0s30f4:1 txonly xdp-drv pps pkts 10.00 rx 0 0 tx 511630 8659520 sock0@enp0s30f4:1 txonly xdp-drv pps pkts 10.00 rx 0 0 tx 511625 13775808 sock0@enp0s30f4:1 txonly xdp-drv pps pkts 10.00 rx 0 0 tx 511619 18892032 Fixes: 132c32ee ("net: stmmac: Add TX via XDP zero-copy socket") Cc: <stable@vger.kernel.org> # 5.13.x Co-developed-by:

commit 552799f8 upstream. Currently, outgoing packets larger than 1496 bytes are dropped when tagged VLAN is used on a switch port. Add the frame check sequence length to the value of the register GSWIP_MAC_FLEN to fix this. This matches the lantiq_ppa vendor driver, which uses a value consisting of 1518 bytes for the MAC frame, plus the lengths of special tag and VLAN tags.
