[ Upstream commit 024b32d ] Unlike what is claimed in commit f5aa7d4 ("drm/bridge: parade-ps8640: Provide wait_hpd_asserted() in struct drm_dp_aux"), if someone manually tries to do an AUX transfer (like via `i2cdump ${bus} 0x50 i`) while the panel is off we don't just get a simple transfer error. Instead, the whole ps8640 gets thrown for a loop and goes into a bad state. Let's put the function to wait for the HPD (and the magical 50 ms after first reset) back in when we're doing an AUX transfer. This shouldn't actually make things much slower (assuming the panel is on) because we should immediately poll and see the HPD high. Mostly this is just an extra i2c transfer to the bridge.

Now the sii902x bridge is ready from DRM's perspective. - sii902x calls sii902x_audio_codec_init() and platform_device_register_data() - The registration of the audio platform device causes probing of the deferred devices. - tidss probes, which eventually causes sii902x_bridge_get_edid() to be called. - sii902x_bridge_get_edid() tries to use the i2c to read the edid. However, the sii902x driver has not set up the i2c part yet, leading to the crash.

commit d76779d upstream. Creating a region with 16 memory devices caused a problem. The div_u64_rem function, used for dividing an unsigned 64-bit number by a 32-bit one, faced an issue when SZ_256M * p->interleave_ways. The result surpassed the maximum limit of the 32-bit divisor (4G), leading to an overflow and a remainder of 0. note: At this point, p->interleave_ways is 16, meaning 16 * 256M = 4G To fix this issue, I replaced the div_u64_rem function with div64_u64_rem and adjusted the type of the remainder.

commit 56062d6 upstream. Presently ia32 registers stored in ptregs are unconditionally cast to unsigned int by the ia32 stub. They are then cast to long when passed to __se_sys*, but will not be sign extended. This takes the sign of the syscall argument into account in the ia32 stub. It still casts to unsigned int to avoid implementation specific behavior. However then casts to int or unsigned int as necessary. So that the following cast to long sign extends the value. This fixes the io_pgetevents02 LTP test when compiled with -m32. Presently the systemcall io_pgetevents_time64() unexpectedly accepts -1 for the maximum number of events. It doesn't appear other systemcalls with signed arguments are effected because they all have compat variants defined and wired up.

So in init_irq_stacks(), the cpu_to_node() does not work, it always return 0. In NUMA, it makes the node 1 cpu accesses the IRQ stack which is in the node 0. This patch fixes it by: 1.) export the early_cpu_to_node(), and use it in the init_irq_stacks(). 2.) change init_irq_stacks() to __init function.

[ Upstream commit ca6f537 ] The SW_INCR event is somewhat unusual, and depends on the specific HW counter that it is programmed into. When programmed into PMEVCNTR<n>, SW_INCR will count any writes to PMSWINC_EL0 with bit n set, ignoring writes to SW_INCR with bit n clear. Event rotation means that there's no fixed relationship between perf_events and HW counters, so this isn't all that useful. Further, we program PMUSERENR.{SW,EN}=={0,0}, which causes EL0 writes to PMSWINC_EL0 to be trapped and handled as UNDEFINED, resulting in a SIGILL to userspace. Given that, it's not a good idea to expose SW_INCR in sysfs.

[ Upstream commit fb366fc ] commit c7aab4f ("netfilter: nf_conntrack_tcp: re-init for syn packets only") introduces a bug where SYNs in ORIGINAL direction on reused 5-tuple result in incorrect window scale negotiation. This commit merged the SYN re-initialization and simultaneous open or SYN retransmits cases. Merging this block added the logic in tcp_init_sender() that performed window scale negotiation to the retransmitted syn case. Previously. this would only result in updating the sender's scale and flags. After the merge the additional logic results in improperly clearing the scale in ORIGINAL direction before any packets in the REPLY direction are received. This results in packets incorrectly being marked invalid for being out-of-window. This can be reproduced with the following trace: Packet Sequence: > Flags [S], seq 1687765604, win 62727, options [.. wscale 7], length 0 > Flags [S], seq 1944817196, win 62727, options [.. wscale 7], length 0 In order to fix the issue, only evaluate window negotiation for packets in the REPLY direction.

commit f6564fc upstream. Alexander Potapenko writes in [1]: "For every memory access in the code instrumented by KMSAN we call kmsan_get_metadata() to obtain the metadata for the memory being accessed. For virtual memory the metadata pointers are stored in the corresponding `struct page`, therefore we need to call virt_to_page() to get them. According to the comment in arch/x86/include/asm/page.h, virt_to_page(kaddr) returns a valid pointer iff virt_addr_valid(kaddr) is true, so KMSAN needs to call virt_addr_valid() as well. To avoid recursion, kmsan_get_metadata() must not call instrumented code, therefore ./arch/x86/include/asm/kmsan.h forks parts of arch/x86/mm/physaddr.c to check whether a virtual address is valid or not. But the introduction of rcu_read_lock() to pfn_valid() added instrumented RCU API calls to virt_to_page_or_null(), which is called by kmsan_get_metadata(), so there is an infinite recursion now. I do not think it is correct to stop that recursion by doing kmsan_enter_runtime()/kmsan_exit_runtime() in kmsan_get_metadata(): that would prevent instrumented functions called from within the runtime from tracking the shadow values, which might introduce false positives." Fix the issue by switching pfn_valid() to the _sched() variant of rcu_read_lock/unlock(), which does not require calling into RCU. Given the critical section in pfn_valid() is very small, this is a reasonable trade-off (with preemptible RCU). KMSAN further needs to be careful to suppress calls into the scheduler, which would be another source of recursion. This can be done by wrapping the call to pfn_valid() into preempt_disable/enable_no_resched(). The downside is that this sacrifices breaking scheduling guarantees; however, a kernel compiled with KMSAN has already given up any performance guarantees due to being heavily instrumented. Note, KMSAN code already disables tracing via Makefile, and since mmzone.h is included, it is not necessary to use the notrace variant, which is generally preferred in all other cases.

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.

commit 486058f upstream. As suggested by Paolo in link[1], if the memory allocation fails, the mm layer will emit a lot warning comprising the backtrace, so remove the print.

commit 46188db upstream. The LPASS WSA macro codec driver is updating the digital gain settings behind the back of user space on DAPM events if companding has been enabled. As compander control is exported to user space, this can result in the digital gain setting being incremented (or decremented) every time the sound server is started and the codec suspended depending on what the UCM configuration looks like. Soon enough playback will become distorted (or too quiet). This is specifically a problem on the Lenovo ThinkPad X13s as this bypasses the limit for the digital gain setting that has been set by the machine driver. Fix this by simply dropping the compander gain offset hack. If someone cares about modelling the impact of the compander setting this can possibly be done by exporting it as a volume control later. Note that the volume registers still need to be written after enabling clocks in order for any prior updates to take effect.

commit b53cc61 upstream. The PA gain can be set in steps of 1.5 dB from -3 dB to 18 dB, that is, in 15 levels. Fix the dB values for the PA volume control as experiments using wsa8835 show that the first 16 levels all map to the same lowest gain while the last three map to the highest gain. These values specifically need to be correct for the sound server to provide proper volume control. Note that level 0 (-3 dB) does not mute the PA so the mute flag should also not be set.

Building outside of the project root, requires `srcroot` to be prepended for paths to resolve to the intended include directories. This is necessary for something like the Nix Linux derivation that sets up a `build/` directory and initiates `make` from it as the working directory.

Hello @martinjlowm Can you please submit this PR against odroid-6.6.y (that is the current kernel for XU4 and N2/N2L) |
|
Sure! Nice to know :) It wasn't as simple as just changing the base branch - I'll rebase it ontop of the other branch either tonight or tomorrow and see if it compiles successfully. |
