[PATCH v7 0/5] mfd: tps6586x: register restart handler

by Benjamin Bara

Hi! The Tegra20 requires an enabled VDE power domain during startup. As the VDE is currently not used, it is disabled during runtime. Since 8f0c714ad9be, there is a workaround for the "normal restart path" which enables the VDE before doing PMC's warm reboot. This workaround is not executed in the "emergency restart path", leading to a hang-up during start. This series implements and registers a new pmic-based restart handler for boards with tps6586x. This cold reboot ensures that the VDE power domain is enabled during startup on tegra20-based boards. Since bae1d3a05a8b, i2c transfers are non-atomic while preemption is disabled (which is e.g. done during panic()). This could lead to warnings ("Voluntary context switch within RCU") in i2c-based restart handlers during emergency restart. The state of preemption should be detected by i2c_in_atomic_xfer_mode() to use atomic i2c xfer when required. Beside the new system_state check, the check is the same as the one pre v5.2. --- v7: - 5/5: drop mode check (suggested by Dmitry) - Link to v6: https://lore.kernel.org/r/20230327-tegra-pmic-reboot-v6-0-af44a4cd82e9@skid… v6: - drop 4/6 to abort restart on unexpected failure (suggested by Dmitry) - 4,5: fix comments in handlers (suggested by Lee) - 4,5: same delay for both handlers (suggested by Lee) v5: - introduce new 3 & 4, therefore 3 -> 5, 4 -> 6 - 3: provide dev to sys_off handler, if it is known - 4: return NOTIFY_DONE from sys_off_notify, to avoid skipping - 5: drop Reviewed-by from Dmitry, add poweroff timeout - 5,6: return notifier value instead of direct errno from handler - 5,6: use new dev field instead of passing dev as cb_data - 5,6: increase timeout values based on error observations - 6: skip unsupported reboot modes in restart handler --- Benjamin Bara (5): kernel/reboot: emergency_restart: set correct system_state i2c: core: run atomic i2c xfer when !preemptible kernel/reboot: add device to sys_off_handler mfd: tps6586x: use devm-based power off handler mfd: tps6586x: register restart handler drivers/i2c/i2c-core.h | 2 +- drivers/mfd/tps6586x.c | 50 ++++++++++++++++++++++++++++++++++++++++++-------- include/linux/reboot.h | 3 +++ kernel/reboot.c | 4 ++++ 4 files changed, 50 insertions(+), 9 deletions(-) --- base-commit: 197b6b60ae7bc51dd0814953c562833143b292aa change-id: 20230327-tegra-pmic-reboot-4175ff814a4b Best regards, -- Benjamin Bara <benjamin.bara(a)skidata.com>

[PATCH v1] usb: typec: class: fix typec_altmode_put_partner to put plugs

by RD Babiera

When releasing an Alt Mode, typec_altmode_release called by a plug device will not release the plug Alt Mode, meaning that a port will hold a reference to a plug Alt Mode even if the port partner is unregistered. As a result, typec_altmode_get_plug() can return an old plug altmode. Currently, typec_altmode_put_partner does not raise issues when unregistering a partner altmode. Looking at the current implementation: > static void typec_altmode_put_partner(struct altmode *altmode) > { > struct altmode *partner = altmode->partner; When called by the partner Alt Mode, then partner evaluates to the port's Alt Mode. When called by the plug Alt Mode, this also evaluates to the port's Alt Mode. > struct typec_altmode *adev; > > if (!partner) > return; > > adev = &partner->adev; This always evaluates to the port's typec_altmode > if (is_typec_plug(adev->dev.parent)) { > struct typec_plug *plug = to_typec_plug(adev->dev.parent); > > partner->plug[plug->index] = NULL; If the routine is called to put the plug's Alt mode and altmode refers to the plug, then adev referring to the port can never be a typec_plug. If altmode refers to the port, adev will always refer to the port partner, which runs the block below. > } else { > partner->partner = NULL; > } > put_device(&adev->dev); > } When calling typec_altmode_set_partner, a registration always calls get_device() on the port partner or the plug being registered, therefore typec_altmode_put_partner should put_device() the same device. By changing adev to altmode->adev, we make sure to put the correct device and properly unregister plugs. The reason port partners are always properly unregistered is because even when adev refers to the port, the port partner gets nullified in the else block. The port device currently gets put().

scsi regression that after months is still not addressed and now bothering 6.1.y users, too

by Thorsten Leemhuis

* @SCSI maintainers: could you please look into below please? * @Stable team: you might want to take a look as well and consider a revert in 6.1.y (yes, I know, those are normally avoided, but here it might make sense). Hi everyone! TLDR: I noticed a regression (Adaptec 71605z with aacraid sometimes hangs for a while) that was reported months ago already but is still not fixed. Not only that, it apparently more and more users run into this recently, as the culprit was recently integrated into 6.1.y; I wonder if it would be best to revert it there, unless a fix for mainline comes into reach soon. Details: Quite a few machines with Adaptec controllers seems to hang for a few tens of seconds to a few minutes before things start to work normally again for a while: https://bugzilla.kernel.org/show_bug.cgi?id=217599 That problem is apparently caused by 9dc704dcc09eae ("scsi: aacraid: Reply queue mapping to CPUs based on IRQ affinity") [v6.4-rc7]. That commit despite a warning of mine to Sasha recently made it into 6.1.53 -- and that way apparently recently reached more users recently, as quite a few joined that ticket. The culprit is authored by Sagar Biradar who unless I missed something never replied even once to the ticket or earlier mails about it. Lore has no messages from him since early June. Hannes Reinecke at least tried to fix it a few weeks ago (many thx), but that didn't work out (see the ticket for details). Since then things look stalled again, which is, ehh, unfortunate when it comes to regressions. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page.
