This is solveable different way and I do not understand this rationale. The driver should not request trigger type but use what DTS is providing, unless of course only one valid trigger is possible. But so far you did not provide any arguments for this. Downstream crappy code? Nope. Existing driver? Same. Was anything here actually checked with datasheets/hardware? Best regards, Krzysztof

The initially open question is unanswered, why sc8280xp CAMSS does specify interrupts as level high type, was it actually checked with datasheets/hardware, as you say it? It has never been tested by anyone and anywhere, downstream or upstream wise, only rising edge interrupts were tested, and they do work. I don't have access to datasheets or hardware of sc8280xp powered board, someone may either verify, if CAMSS level high type interrupts are supported/working at all or not (obviously its current presence in dts is insufficient), or check the SoC datasheet. To sum up, the intention of this change: 1) fix the unpleasant runtime issue with no regressions (it's been tested), 2) align CAMSS device description in firmware with known to work well IP hardware configuration. -- Best wishes, Vladimir

If downstream has a bug, but somehow works, you will implement the same bug upstream? Downstream is well known of shortcuts, incomplete solutions and crappy code, which passes some tests but might not be really correct. I understand that downstream can be a supportive case, but not for level of interrupts! People, not only downstream but it's even worse there, do not see the difference between level and edge, between GPIO ACTIVE_HIGH and ACTIVE_LOW. > >> Nope. Existing driver? Same. > > The existing driver works, that's the argument to support the change. We are not going to get into such discussions. Code might be incorrect, but mostly works because race issues are very tricky to spot, yet you use that code as argument to say hardware is like that. No. Hardware is not because driver is written that way. > >> Was anything here actually checked with datasheets/hardware? > > The initially open question is unanswered, why sc8280xp CAMSS does This is about all CAMSS, not only sc8280xp. > specify interrupts as level high type, was it actually checked with > datasheets/hardware, as you say it?

I've tested both as was submitted and your change. I _always_ test my patches. I'm not sure there's a datasheet which spells this out to be honest. Rising or High can both be justified, its really down to how your interrupt controller latches the state change. However I personally am fine with the change you've provided because I trust it fixes an error for you. I didn't try loading and unloading that module but, since you did I'm happy to Ack the change and trust your work. --- bod

All what you see and on any variant of CAMSS device tree node is rising edge interrupt, this is the type requested by the driver, and I believe you've tested the driver. > I _always_ test my patches.

Please share the change to the driver, which you've used to test high level type of interrupts, shall it be send for upstream inclusion?

However I personally am > fine with the change you've provided because I trust it fixes an error > for you. That's a GIC, right? So most of the GIC interrupts are level high. I can easily imagine that 10 years ago one engineer made mistake and wrote camss downstream DTS with edge and this kept going, because "99.999% it works" and no one will ever hit that 0.001%. And if it is hit, we blame something else because debugging is very difficult. If this entire patchset is based on downstream driver code, not datasheets, then it should be clearly explained in commit msg, not just "The expected type is...". Why? Because "the expected type" means datasheet or some hardware engineer says it, not driver. Best regards, Krzysztof

Or you just checked that "interrupt works"? Right from the beginning and any other day CAMSS interrupts are tested as rising edge interrupts.

CAMSS IP configuration, in particular interrupt type, is done by the upstream driver, note that the fixes in this changeset is also sent against the upstream driver, tested on the upstream driver etc. -- Best wishes, Vladimir

You said "device description in firmware" and "IP hardware configuration", but now speak about drivers. Best regards, Krzysztof

Why some irrelevant imaginary "races" are into the discussion, have you or any other CAMSS user ever seen them? If no, this argument shall be excluded.

Every single user of CAMSS test only rising edge type of interrupts of the IP. What are the races you are talking about? I kindly ask to read the cover letter, it describes the problem fixed by the changeset. >>>> 2) align CAMSS device description in firmware with known to work well >>>> IP hardware configuration. >>> >>> Where is this description in firmware?

You said "device description in firmware" and "Device description in firmware" is DTB. > "IP hardware configuration", but now speak about drivers. > "IP hardware configuration" is done by the driver, this terminology does not cause any surprises or ambiguity, I hope. It's been always that "IP hardware configuration" of CAMSS interrupt types completely ignores "device description in firmware" of CAMSS interrupt types. By design due to endless problems with firmware like the one under discussion interrupt types derived from firmware are ignored, and their correction in DTS is problematic for whatever reason. -- Best wishes, Vladimir

I tried running libcamera "cam" application to capture a data stream before and after your change - from memory at least on the sc8280xp and I think on 8250 too. What I haven't tested is unloading and reloading the kernel module. My understanding of your bug report is your change fixes an error on reload. ? --- bod

Nobody has ever tested high level type of CAMSS interrupts, and there is no reason why they are specified in the platform dtsi file, but I repeat myself. > What I haven't tested is unloading and reloading the kernel module.
