[PATCH 2/2] drm/ofdrm: Update expected device name

by Cyril Brulebois

Since commit 241d2fb56a18 ("of: Make OF framebuffer device names unique"), as spotted by Frédéric Bonnard, the historical "of-display" device is gone: the updated logic creates "of-display.0" instead, then as many "of-display.N" as required. This means that offb no longer finds the expected device, which prevents the Debian Installer from setting up its interface, at least on ppc64el. Given the code similarity it is likely to affect ofdrm in the same way. It might be better to iterate on all possible nodes, but updating the hardcoded device from "of-display" to "of-display.0" is likely to help as a first step.

amd_sfh driver causes kernel oops during boot

by Haochen Tong

Hi, Since kernel 6.3.0 (and also 6.4rc3), on a ThinkPad Z13 system with Arch Linux, I've noticed that the amd_sfh driver spews a lot of stack traces during boot. Sometimes it is an oops: BUG: unable to handle page fault for address: 000000000001000f #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP NOPTI CPU: 8 PID: 457 Comm: (udev-worker) Not tainted 6.3.3-arch1-1 #1 fa7b7e0107004b3021a57a74b951e0a25e7e8584 Hardware name: LENOVO 21D2CTO1WW/21D2CTO1WW, BIOS N3GET47W (1.27 ) 12/08/2022 RIP: 0010:amd_sfh_get_report+0x1e/0x110 [amd_sfh] Code: 90 90 90 90 90 90 90 90 90 90 90 90 66 0f 1f 00 0f 1f 44 00 00 41 57 41 56 41 55 41 54 55 53 48 8b 87 60 1d 00 00 48 8b 68 08 <8b> 45 10 85 c0 0f 84 a9 00 00 00 49 89 fc 41 89 f7 41 89 d6 31 db RSP: 0018:ffffb164426f3a20 EFLAGS: 00010246 RAX: ffff9b0ae6b7bd00 RBX: ffff9b0ac0f46000 RCX: 0000000000000000 RDX: 0000000000000002 RSI: 0000000000000002 RDI: ffff9b0ac0f46000 RBP: 000000000000ffff R08: ffffb164426f3ab8 R09: ffffb164426f3ab8 R10: 000000000020031b R11: ffff9b0ace40ac00 R12: ffff9b0ace40ac00 R13: 0000000000000002 R14: 0000000000000002 R15: ffff9b0acd213010 FS: 00007fe9ceb82200(0000) GS:ffff9b1122000000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000000000001000f CR3: 000000010940c000 CR4: 0000000000750ee0 PKRU: 55555554 Call Trace: <TASK> amdtp_hid_request+0x36/0x50 [amd_sfh 2e3095779aada9fdb1764f08ca578ccb14e41fe4] sensor_hub_get_feature+0xad/0x170 [hid_sensor_hub d6157999c9d260a1bfa6f27d4a0dc2c3e2c5654e] hid_sensor_parse_common_attributes+0x217/0x310 [hid_sensor_iio_common 07a7935272aa9c7a28193b574580b3e953a64ec4] hid_gyro_3d_probe+0x7f/0x2e0 [hid_sensor_gyro_3d 9f2eb51294a1f0c0315b365f335617cbaef01eab] platform_probe+0x44/0xa0 really_probe+0x19e/0x3e0 ?

[PATCH v4 1/3] mm: Call arch_swap_restore() from do_swap_page()

by Peter Collingbourne

Commit c145e0b47c77 ("mm: streamline COW logic in do_swap_page()") moved the call to swap_free() before the call to set_pte_at(), which meant that the MTE tags could end up being freed before set_pte_at() had a chance to restore them. Fix it by adding a call to the arch_swap_restore() hook before the call to swap_free().

[PATCH] powerpc/boot: Disable power10 features after BOOTAFLAGS assignment

by Nathan Chancellor

When building the boot wrapper assembly files with clang after commit 648a1783fe25 ("powerpc/boot: Fix boot wrapper code generation with CONFIG_POWER10_CPU"), the following warnings appear for each file built: '-prefixed' is not a recognized feature for this target (ignoring feature) '-pcrel' is not a recognized feature for this target (ignoring feature) While it is questionable whether or not LLVM should be emitting a warning when passed negative versions of code generation flags when building assembly files (since it does not emit a warning for the altivec and vsx flags), it is easy enough to work around this by just moving the disabled flags to BOOTCFLAGS after the assignment of BOOTAFLAGS, so that they are not added when building assembly files. Do so to silence the warnings. Cc: stable(a)vger.kernel.org Fixes: 648a1783fe25 ("powerpc/boot: Fix boot wrapper code generation with CONFIG_POWER10_CPU") Link: https://github.com/ClangBuiltLinux/linux/issues/1839 Reviewed-by: Nicholas Piggin <npiggin(a)gmail.com> Signed-off-by: Nathan Chancellor <nathan(a)kernel.org> --- I do not think that 648a1783fe25 is truly to blame for this but the Fixes tag will help the stable team ensure that this change gets backported with 648a1783fe25.

[PATCH v2] powerpc/bpf: populate extable entries only during the last pass

by Hari Bathini

Since commit 85e031154c7c ("powerpc/bpf: Perform complete extra passes to update addresses"), two additional passes are performed to avoid space and CPU time wastage on powerpc. But these extra passes led to WARN_ON_ONCE() hits in bpf_add_extable_entry() as extable entries are populated again, during the extra pass, without resetting the index. Fix it by resetting entry index before repopulating extable entries, if and when there is an additional pass.

Right. So for your device, the correct behavior would be to do nothing, wouldn't it? The packets would be delivered and the host needs to filter and discard unrequested packets. > Currently we are setting these bits to 0 indicating no capabilities on our device and still we observe that Host (Linux kernel host cdc driver) has been sending requests specific to these capabilities. > > Please let me know if there is a better way to indicate host that device does not have these capabilities. no you are doing things as they are supposed to be done and the host is at fault.

[REGRESSION][BISECTED] Boot stall from merge tag 'net-next-6.2'

by Sami Korkalainen

Linux 6.2 and newer are (mostly) unbootable on my old HP 6730b laptop, the 6.1.30 works still fine. The weirdest thing is that newer kernels (like 6.3.4 and 6.4-rc3) may boot ok on the first try, but when rebooting, the very same version doesn't boot. Some times, when trying to boot, I get this message repeated forever: ACPI Error: No handler or method for GPE [XX], disabling event (20221020/evgpe-839) On newer kernels, the date is 20230331 instead of 20221020. There is also some other error, but I can't read it as it gets overwritten by the other ACPI error, see image linked at the end. And some times, the screen will just stay completely blank. I tried booting with acpi=off, but it does not help. I bisected and this is the first bad commit 7e68dd7d07a2 "Merge tag 'net-next-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next" As the later kernels had the seemingly random booting behaviour (mentioned above), I retested the last good one 7c4a6309e27f by booting it several times and it boots every time. I tried getting some boot logs, but the boot process does not go far enough to make any logs.

[iwlwifi] 6.3 regression, AX201 crash on traffic activity with Pixel 7, bisected

by evgeny nikiforov

Hello I have a laptop with Intel Wi-Fi 6 AX201. After updating from 6.2 to 6.3, I'm experiencing wifi crashes, wifi restart when traffic is flowing with Pixel 7 Pro (wifi 6E/802.11ax). Other older wifi devices probably not affected (tried Xiaomi pad with wifi 5/802.11ac). Tested with iperf3 in both directions, rsyncing Pixel photos to laptop, via router (wifi 5) or via Pixel wifi hotspot. The whole system freezes for seconds, no cursor movements possible at these moments (libinput "Touch jump detected and discarded" in logs indicating this). No problem with the 6.2 kernel. Bisecting leads to this commit of bumping FW API to 74 9ad1e7e5b0c488e4518edd698238a87ac6a73caa, looking strange to me, but reverting from 74 to 72 in 6.3 indeed successful with no crash.
