* [PATCH] usb: typec: ucsi: Do not call ACPI _DSM method for UCSI read operations @ 2024-08-30 8:43 Saranya Gopal 2024-08-30 8:44 ` Heikki Krogerus 0 siblings, 1 reply; 11+ messages in thread From: Saranya Gopal @ 2024-08-30 8:43 UTC (permalink / raw) To: linux-usb; +Cc: gregkh, rajaram.regupathy, Saranya Gopal, Heikki Krogerus ACPI _DSM methods are needed only for UCSI write operations and for reading CCI during RESET_PPM operation. So, remove _DSM calls from other places. While there, remove the Zenbook quirk also since the default behavior now aligns with the Zenbook quirk. With this change, GET_CONNECTOR_STATUS returns at least 6 seconds faster than before in Arrowlake-S platforms.

However, this is a very minor corner case. It could be fixed by adding an optional ->poll() method or similar that is NULL on other implementations and does the DSM READ on ACPI. We could then call this before read_cci when polling for completion. If this is done ->read_cci() would never call the DSM method. However, the change in its current state is a definitive improvement, and looks good to me. Thus feel free to add Reviewed-by: Christian A.

The other part still needs a fix. > So, can this patch go in as it is? > Please let me know if I need to resubmit with any changes. If you prefer that we go with Christian's patch to fix the issue - which is fine by me - you need to rebase this on top of his patch in any case. So you will need to resend this either way. Christian would you mind resending that second patch after all where you take the Zenbook quirk into use on that ASUS system? Let's make that as the actual fix for the issue. Maybe it's more clear that way. thanks, > > > Christian, can you check this? > > > > The change certainly looks like the correct thing to do and would > > remove the need for the zenbook quirk.

Well technically not. I've established with the reporter of https://bugzilla.kernel.org/show_bug.cgi?id=219108 that the immediate regression (keyboard on ASUS laptop not working) is fixed with the ucsi.c patch (that got your Reviewed-By today) alone. UCSI on the ASUS laptop is still broken but it always was, AFAICT. Thus I'd like to push the above mentioned patch as the fix for the regression. The reporter was very helpful and responsive in testing and I intend to look into the reason why UCSI does not work after that with the reporter's help. > On Thu, 5 Sept 2024 at 20:00, Christian A.

The immediate regression is fixed with the already reviewed patch alone. The remaining issue with UCSI on the ASUS laptop not working can be fixed separately. I'd rather base a fix for UCSI on the ASUS laptop onto Saranya's patch because I think that patch is the correct thing to do. Unfortunately, testing by the original reporter was inconclusive wrt. this. I have one report of a test run with the (classical) ASUS quirk (and the other patch) where UCSI on the ASUS laptop did work. Patch version v1 was the result of this. With Saranya's patch and my patch to ucsi.c the regression was gone but UCSI did _not_ work. As this does not make sense because Saranya's patch should be equivalent to the ASUS zenbook quirk. Thus this needs more investigation and dropping the zenbook quirk patch looks like the correct thing to do. > Let's make that as the actual fix for the issue. Maybe it's more clear > that way. Please let me know if you disagree and I can resend the ASUS quirk patch. Best regards, Christian ^ permalink raw reply [flat|nested] 11+ messages in thread

So we go ahead with this patch from Saranya as is - we don't caim it fixes anything. Then you guys continue debugging that UCSI not working on the ASUS laptop issue.

It has been mere hours since the merge window closed and I could even consider applying this change. Please relax and understand the ecosystem in which you are working in (also remember the weeks of conferences most of us have been at right now.) To help make this work better, please take the time to review other pending patches for the subsystem, which will ensure that your changes get moved to the top as others get reviewed. I'll wait for you to do that before getting to this one... thanks, greg k-h ^ permalink raw reply [flat|nested] 11+ messages in thread
