<CounterPillow> Question, why does this code abort if firmware says something non-fatally wrong? This breaks boot on some platforms https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/firmware/arm_scmi/base.c?h=next-20220503&id=3b0041f6e10e5bdbb646d98172be43e88734ed62
<CounterPillow> cc sudeepholla_
<sudeepholla_> CounterPillow, interesting
<sudeepholla_> CounterPillow, may I ask which platform ?
<CounterPillow> rockchip rk3568 according to one user in #linux-rockchip
<CounterPillow> <amazingfate> arm-scmi firmware:scmi: Malformed reply - real_sz:8 calc_sz:4, t->rx.len is 12, sizeof(u32) is 4, loop_num_ret is 3
<CounterPillow> possibly an off-by-one error in their firmware, though this seems non-fatal as it worked fine before that commit, and after this commit no longer gets the clocks for CPU and GPU.
<sudeepholla_> CounterPillow, we just added a check and here we are finding bugs in the firmware
<sudeepholla_> CounterPillow, we could probably relax with just warning but wonder if that may cause fatal issue on some other platform
<CounterPillow> Out of curiosity, is there an scmi conformance test suite vendors can run?
torez has joined #armlinux
<sudeepholla_> CounterPillow, there used to be one, just learnt it is not maintained anymore(I am told) and we plan to fix that soon, not sure if that helps you now :(
<sudeepholla_> CounterPillow, let us see if this f/w can be fixed, else we can workaround in the kernel, we still have time before the release
<sudeepholla_> CounterPillow, can you shoot any email on the list pulling the rk3568 maintainers if you are not the one ;)
<CounterPillow> Unfortunately the firmware is closed source, but if you have contacts at rockchip: it's rk3568_bl31_v1.32.elf
<sudeepholla_> CounterPillow, sorry if you are, I am not aware
<CounterPillow> I'm not the maintainer of anything other than the audio driver on that SoC
<sudeepholla_> CounterPillow, we can pull the maintainer who maintains the platform upstream
<sudeepholla_> just post the email with the report on the list with logs if you can
<CounterPillow> which list? the arm one, with the rockchip one in cc ?
<sudeepholla_> Heiko Stuebner <heiko@sntech.de>
<sudeepholla_> he is the maintainer I guess
<CounterPillow> yeah, though he also has no access to firmware sources
<sudeepholla_> CounterPillow linux-arm-kernel@lists.infradead.org
<sudeepholla_> CounterPillow, but he must have some contact, no ?
headless has quit [Quit: Konversation terminated!]
<CounterPillow> I'll also cc Liang Chen <cl@rock-chips.com> they seem to have committed the firmware to the rkbin repo
<sudeepholla_> CounterPillow, if not we will workaround as it is not fatal as you mentioned
<sudeepholla_> CounterPillow, i just don't want to rush and give no incentive for the f/w to be fixed
<CounterPillow> I see, thanks
<CounterPillow> I'll write the e-mail then
<sudeepholla_> CounterPillow, don't worry we will fix before the final release for sure, I understand your concern
<sudeepholla_> CounterPillow, we found this in our test setup and thought good to have check which seem to have unearthed the bug but due to the nature of f/w release we may need to workaround which is not an issue
<CounterPillow> Alright

<hanetzer> question. does a given device driver need to be programmed specifically to take 'pinctrl-0' and such?
