I added the touchscreen patch to wip/msm8916/6.5-rc4. The display commit looks fine except for one tiny detail. As far as I can tell

  • A5 has the EA8061V_AMS497EE01 panel
  • E5 has the EA8061V_AMS497EE10 panel

Those are very similar but there are still some subtle differences. It seems to be mostly related to the brightness stuff:

@Grimler91 Perhaps you have an opinion if these differences are worth handling and how hard it would be with the brightness support in your PR? I still don't have a good understanding how the brightness stuff works.

Haven't looked into the vendor kernel code yet, but from dts differences above it seems like we could quite easily extend the ams497ee01 driver to be fully compatible with ams497ee10 as well, I'll look at doing that

Can you generate a separate panel driver for e5 for now? I know it will probably end up being identical, but that way we can merge it independently even if the a5 one gets brightness support.

I would leave the display panel part for now. It would be great if a device owner continues with the works and actually tests it.

arm64: bpf: fix 32bit unconditional bswap
47f9248 
[ Upstream commit a51cd6b ]

In case when is64 == 1 in emit(A64_REV32(is64, dst, dst), ctx) the
generated insn reverses byte order for both high and low 32-bit words,
resuling in an incorrect swap as indicated by the jit test:

Fix this by forcing 32bit variant of rev32.

nvmet: make nvmet_wq unbound
34cfb09 
When deleting many controllers one-by-one, it takes a very
long time as these work elements may serialize as they are
scheduled on the executing cpu instead of spreading. In general
nvmet_wq can definitely be used for long standing work elements
so its better to make it unbound regardless.

gpiolib: fix the speed of descriptor label setting with SRCU
a86d276 
Commit 1f2bcb8 ("gpio: protect the descriptor label with SRCU")
caused a massive drop in performance of requesting GPIO lines due to the
call to synchronize_srcu() on each label change. Rework the code to not
wait until all read-only users are done with reading the label but
instead atomically replace the label pointer and schedule its release
after all read-only critical sections are done.

To that end wrap the descriptor label in a struct that also contains the
rcu_head struct required for deferring tasks using call_srcu() and stop
using kstrdup_const() as we're required to allocate memory anyway. Just
allocate enough for the label string and rcu_head in one go.

nfc: nci: Fix kcov check in nci_rx_work()
19e35f2 
Commit 7e8cdc9 ("nfc: Add KCOV annotations") added
kcov_remote_start_common()/kcov_remote_stop() pair into nci_rx_work(),
with an assumption that kcov_remote_stop() is called upon continue of
the for loop. But commit d24b035 ("nfc: nci: Fix uninit-value in
nci_dev_up and nci_ntf_packet") forgot to call kcov_remote_stop() before
break of the for loop.

mptcp: only allow set existing scheduler for net.mptcp.scheduler
6963c50 
The current behavior is to accept any strings as inputs, this results in
an inconsistent result where an unexisting scheduler can be set:

  # sysctl -w net.mptcp.scheduler=notdefault
  net.mptcp.scheduler = notdefault

This patch changes this behavior by checking for existing scheduler
before accepting the input.

appletalk: Improve handling of broadcast packets
2e82a58 
When a broadcast AppleTalk packet is received, prefer queuing it on the
socket whose address matches the address of the interface that received
the packet (and is listening on the correct port). Userspace
applications that handle such packets will usually send a response on
the same socket that received the packet; this fix allows the response
to be sent on the correct interface.

If a socket matching the interface's address is not found, an arbitrary
socket listening on the correct port will be used, if any. This matches
the implementation's previous behavior.

Fixes atalkd's responses to network information requests when multiple
network interfaces are configured to use AppleTalk.
