2024-01-26MAINTAINERS: Add Andreas Larsson as co-maintainer for arch/sparcAndreas Larsson1-0/+1
Dave has not been very active on arch/sparc for the past two years. I have been contributing to the SPARC32 port as well as maintaining out-of-tree SPARC32 patches for LEON3/4/5 (SPARCv8 with CAS support) since 2012. I am willing to step up as an arch/sparc (co-)maintainer. For recent discussions on the matter, see [1] and [2].

2024-01-26drm: bridge: samsung-dsim: Don't use FORCE_STOP_STATEMichael Walle1-30/+2
The FORCE_STOP_STATE bit is unsuitable to force the DSI link into LP-11 mode. It seems the bridge internally queues DSI packets and when the FORCE_STOP_STATE bit is cleared, they are sent in close succession without any useful timing (this also means that the DSI lanes won't go into LP-11 mode). The length of this gibberish varies between 1ms and 5ms. This sometimes breaks an attached bridge (TI SN65DSI84 in this case). In our case, the bridge will fail in about 1 per 500 reboots. The FORCE_STOP_STATE handling was introduced to have the DSI lanes in LP-11 state during the .pre_enable phase. But as it turns out, none of this is needed at all. Between samsung_dsim_init() and samsung_dsim_set_display_enable() the lanes are already in LP-11 mode. The code as it was before commit 20c827683de0 ("drm: bridge: samsung-dsim: Fix init during host transfer") and 0c14d3130654 ("drm: bridge: samsung-dsim: Fix i.MX8M enable flow to meet spec") was correct in this regard. This patch basically reverts both commits. It was tested on an i.MX8M SoC with an SN65DSI84 bridge. The signals were probed and the DSI packets were decoded during initialization and link start-up. After this patch the first DSI packet on the link is a VSYNC packet and the timing is correct. Command mode between .pre_enable and .enable was also briefly tested by a quick hack. There was no DSI link partner which would have responded, but it was made sure the DSI packet was send on the link. As a side note, the command mode seems to just work in HS mode. I couldn't find that the bridge will handle commands in LP mode.

2024-01-26LoongArch/smp: Call rcutree_report_cpu_starting() at tlb_init()Huacai Chen2-7/+10
Machines which have more than 8 nodes fail to boot SMP after commit a2ccf46333d7b2cf96 ("LoongArch/smp: Call rcutree_report_cpu_starting() earlier"). Because such machines use tlb-based per-cpu base address rather than dmw-based per-cpu base address, resulting per-cpu variables can only be accessed after tlb_init(). But rcutree_report_cpu_starting() is now called before tlb_init() and accesses per-cpu variables indeed. Since the original patch want to avoid the lockdep warning caused by page allocation in tlb_init(), we can move rcutree_report_cpu_starting() to tlb_init() where after tlb exception configuration but before page allocation.

This needs to be set to 1 to avoid a potential deadlock in the GC 10.x and newer. On GC 9.x and older, this needs to be set to 0. This can lead to hangs in some mixed graphics and compute workloads.
