• gpio on x86

    From Gerrit Kuehn@2:240/12 to * on Thursday, May 12, 2022 18:33:52
    Hello *!

    I have an Intel-based mainboard with build-in gpios that I'd like to use. However, I cannot get the kernel (5.16) to recognise the chip (NXP PCA9554). To my understanding, this should be supported with the gpio_pca953x kernel module. Upon loading this, the kernel reports no device or chip found, so all further actions via /sys/class/gpio/ or gpioinfo return nothing.

    Any ideas what I might be missing here?

    Hey Gerrit!

    Any ideas what I might be missing here?

    $ zgrep PCA953 /proc/config.gz
    CONFIG_GPIO_PCA953X=m
    # CONFIG_GPIO_PCA953X_IRQ is not set
    CONFIG_LEDS_PCA9532=m
    # CONFIG_LEDS_PCA9532_GPIO is not set

    Note that in my case they are turned off and therefore the kernel reports no device or chip found especially considering I don't have said chipset. However even if I did it should still report no device or chip found.

    Turning on the PCA953X (modular or builtin) should help your cause and is the only idea I can come up with not knowing if your kernel is actually PCA953X capable.

    No.

    But some functions of some boards can be disabled in the bios or by jumper settings. If you're sure that the gpio are active on the hardware side then continue with software troubleshooting.

    Well, the modules are of course loaded (I thought that was clear from what I wrote before). However, they don't find the chip which is definitely there (it's in the documentation and the board has the corresponding connectors).

    There is no BIOS setting for this. Searching the web, I found one or two people reporting the same problem with the same hardware (with older kernels), but unfortunately no solution.

    I don't think I'd need these. IRQ handling can be done (or not), and the LED driver is further down the userland road (and to make it even more confusing, there is leds_pca955x that would fit the chip I have). Same for i2c and sma modules.
    However, my understanding is that the gpio_pca953x module should already report the chip in dmesg when being probed, and this does not happen. Everything else is useless if this first step fails.

    I did use legacy/csm for quite some time if available. However, meanwhile uefi works fine for me and is actually easier to set up and maintain, so I use it on all new machines now.

    From looking at the source, I think it should be supported by the existing module. kernelconfig has the same info:

    Undertood. I am not quite at that point yet but at least I have one working with uefi. Unfortunetly I cannot get the 4k monitor into kicking in before the boot penguins appear and thus I get only 9 of 16 on the top of the screen which disappear as soon as the higher resolution kicks in. Not sure it is worth losing sleep over but I'd sure like to see the rest of the penguins which I know are there ... sort of.

    Sounds like a bit of a luxury problem indeed. ;)
    But you're right, modern monitors are often surprisingly slow in finding signals. But that's probably with no regard to using uefi or legacy boot.

    Heh, heh. Nice for a change. It is usually el-cheapo crap problems in this neck of the woods. Not that any of this is mission critical but to quote Yosimite Sam, "I paid my five bits to see the high diving act and I am GONNA see the high diving act!"

    But you're right, modern monitors are often surprisingly slow in
    finding signals.

    I am going to try a test kernel with all the amdgpu stuff builtin as that might fix this luxury problem without further breaking the bank.

    I need a bigger budget.

    But that's probably with no regard to using uefi or legacy boot.

    There is a difference. With uefi I get boot penguins but not with a legacy boot, or at least not when deploying i915 or amdgpu. I have both now so I can easily check. I can't speak about amdgpu with respect to 4.x kernels but i915 was working with legacy boots. However I predict that 5.18.x kernels will find things getting noticably better. We'll soon enough see.

    Really? It took 4 or 5 days until i got my fido server up and running again. The only task i wanted to do was to move the system from a 4TB disk to a 2TB disk. To reduce the partition sizes i created the target tables from a rescue boot and rsync'd the files to their destinatitions. The partition layout was the same but with differnt size and the system failed to boot.

    I'm not sure that understood anything but i looks like uefi is a mini grub within the bios. The boot device is added to the uefi boot list by uuid.

    If you replace a disk on the same sata port with a newly formated disk of the same layout the boot will fail because the uuid are different.

    This failure will repeat for any file based restore within grub and within the system itself because after grub the uuid of the initrd and in the /etc/fstab will not match any more.

    I've no idea what the final correct solution was. Finally i was so p'd off that i dd'd the whole partitions sda1/sda2... to the new destination. I think that would kept the uuid intact and after three successful reboots i put my hands of the running systems.

    I can't see the improvement there. To keep a track of the activ uuids i started to record blkid output into fstab.

    The best improvement was to make use of my pxe server for the rescue boots. Regards

    Also when installed it manually. Even for FreeBSD. This is the default naming scheme from the EFI standard. It has nothing to do with any particular boot manager.

    I does find the disk. My first step was to remove the old disk and install a fresh system until ready to boot. It did and i removed the new disk to re-attach the old one. Then no boot anymore. The old disk on the same port in place of the new disk did not boot. I think that's because the bios does use some ID flags to identify the disk to boot of. I never noticed that kind of behavior on legacy systems.

    Hey Kai!

    It did and i removed the new disk to re-attach the old one. Then
    no boot anymore.

    I have the identical issue between nvme and sata. On legacy it was never an issue and usually F11 ... or F12 ... on bootup would allow one to change from the default boot disk. With UEFI it has been hit and miss but usually I can get sda to boot up if nvme fails to be seen which can and does happen.

    Life is good,
    Maurice

    new disk to re-attach the old one. Then no boot anymore. The old disk
    on the same port in place of the new disk did not boot. I think
    that's because the bios does use some ID flags to identify the disk
    to boot of. I never noticed that kind of behavior on legacy systems.

    For being EFI-bootable, the installation will need an EFI-partition with boot loader. Your description said your EFI partition was empty (no bootlader). This will not be recognised as bootable by the BIOS (of course).Maybe it was booting legacy before, and you changed the BIOS setting to EFI only?

    Interestingly, this never worked reliably for me, neither with MBR nor with UEFI. The only safe way is to change BIOS boot order settings.

    On the bright side, UEFI does reliably come with a shell (if everything else fails) that allows starting other systems manually.

    Hey Gerrit!

    Interestingly, this never worked reliably for me, neither with MBR
    nor with UEFI. The only safe way is to change BIOS boot order
    settings.

    That precludes that the bios recognizes the disk and presents itself as a bootable disk, which in this case is having issues with the nvme disk. Currently the only repeatable, reliable boot disk is the sata interface.

    Also, while I am at it, the 16 boot penguins on a 4k monitor still requires work.

    Just the disk. I'm not sure if i recognize an efi boot option. The disk is listed in the boot options by its part or model nummer.

    No. With this knowledge i would say that i did boot on legacy mode always. And i still do. I'm sorry to blame efi for that because it can't be a fault of efi if efi is not used. But my perception is that this behavior change was with the uefi bios introduction.

    I talked about cases where something is broken and your system doesn't boot (maybe not even the bootmanager comes up). With MBR this means reconfiguring BIOS boot order, probably getting some USB media to boot a rescue system from it etc.
    With the built-in UEFI shell, you can already check your partitions and even select what to boot without having to reconfigure anything or to provide a rescue system on USB. In many cases I was able to manually boot the failed system with this and use the system itself then to fix booting.

    Some manufacturers provide firmware and bios update tools on efi meanwhile. In that case, you can just drop the new firmware and the upgrade tool on a USB stick and use UEFI-shell to run it from there. In the MBR-days you would have needed to have a MSDOS-system on the USB stick in addition (and hope that the manufacturer would still provide a DOS-based update tool that is able to run on your newly bought server or workstation).

    You have to enter the uefi shell by the same way: Dive into the BIOS and select it. If the system doesn't boot the boot override function is essential.

    I couldn't. The, no, my uefi shell is not self explaining. I failed to start a running system from the uefi shell. Well, ok, my fault.

    So i have to wait until my BIOS company updates it's tools and i can save them within the BIOS. Back in the old days i had my OS/2 bootmanager and rescue system on a small partition.

    In the MBR-days you would have needed to have a MSDOS-system on the

    Why DOS? We need to kickstart the boot sequence.
    USB stick in addition? I see an EFI partition on my disk in addition.

    I've done 50% reading of an efi turorial now and it does remind me to grub.

    (and hope that the manufacturer would still provide a DOS-based
    update tool that is able to run on your newly bought server or workstation).

    I'v seen an EFI editor which my bios doesn't have. Now i've to check if anyone provides this efi software. The default path in my uefi shell does have something like fs[01234]:/efi/tools. The design concept is to add tools from a maintenance/rescue partition like we did before from the usb stick or from a /boot partition.

    Maybe the only thing i need is to get used to it...

    I was talking about updating BIOS or firmware in your system here, not getting a broken system online again. Updating usually involves some kind of Windows software. As I don't use Windows, this doesn't help me. The fallback option usually is something DOS-based (if it exists), but this requires some extra steps. Having a EFI-based update tool is less of a hassle.

    I'v seen an EFI editor which my bios doesn't have. Now i've to check
    if anyone provides this efi software.

    Which software are you looking for? Most things can be set up with efibootmgr under Linux (or FreeBSD).

    Ups, i deleted that part. My point was that we have wait for the manufacturers to provide firmware. This does happen out of our control anyway. No matter if uefi or csm - in both cases we have to rely to the manufacturer. My bios does have a flashtool inclueded but i have to format an usb storage device to fat32 and copy the bios to it. I don't see much difference if i dd an image or copy the file. I see the efi partition as somthing like a permanent usb stick.

    Same task, we need to kickstart the boot sequence. The differnce between uefi and csm is the storage location of the whatever starting software.

    Updating usually involves some kind of Windows software.

    My last one extracted a windows disk imager and copied the image to floppy. Those are self-extraction compressed exes sometimes that can be unzipped or unarj'd to get the real image.

    I'v seen an EFI editor which my bios doesn't have. Now i've to
    check if anyone provides this efi software.

    Which software are you looking for?

    None. It looked like ee. uefi adds a layer of complexity. If i want to use uefi like a rescue system i can't simply use my known tools from my disk. I think i will stick on my rescue stick in case of trouble because the tools i'm used to are available.

    The difference is that without UEFI you need DOS on the USB stick, not just your BIOS flash tool and image. Ever tried booting modern server-hardware under DOS and running BIOS-update tools from that?

    No, we need to come up with an environment that is able to run the flash tool the manufacturer provides. If this tool is for EFI shell, this is easy. Getting a DOS tool to run under DOS booted from a USB stick... your mileage may vary.

    I didn't mean to say that EFI might fully replace your rescue disk (whatever it looks like), it certainly doesn't. But in some at least for me quite common cases where you just want to get the system booted it serves that purpose and relieves me from having to boot the rescue disk.

    No matter what OS runs for those tools - we still need to kickstart them.

    This is the responsiblity of the hardware manufacturer. Btw, let's look on the uefi shell. It can read partitions and filesystems and load/start software from. Do you remember toms root boot on a floppy disk? Basically it does the same. The uefi shell is not a shell of the bios - it's an operating system. If the flash tool is efi software the efi shell OS could be placed on the USB stick too. And again, the only job of the BIOS (remember it's BASIC IO) is to kickstart the boot sequence for an OS.

    I didn't mean to say that EFI might fully replace your rescue disk (whatever it looks like), it certainly doesn't. But in some at least

    I'm sorry to say that i can't take a closer look now. I'm sure there was something like upload but i'm unsure if it was upload for the ipmi image or the bios image. I got a working PXE boot before i got an ipmi board so i continued with PXE and did't dive into the details of ipmi standards.

    On the other hand i think ipmi would be incomplete without bios update function because it's designed for remote system administration. As far as i remember it can load the boot image and at least that way it can load the flash disk with OS and flash tools.

    Depends. Supermicro, e.g., offers both. But only IPMI firmware updates are for free, For being able to update the mainboard's BIOS via IPMI, you have to buy a license key (or hack it). Updating firmware or bios of plugin cards like storage controllers is a completely different kettle of fish, again.

    Sounds like you need network manager & friends.

    We got it working today with wpa_supplicant and dhclient! :)

    Good stuff. LFS is (one of) my favorite things these days.

    Hey Andrew!

    Someone asked about running Synchronet BBS in a docker container.

    I was thinking more along the line of a standard ansi-type bbs except in my case it would serve up the 'linux' terminal which in my case also happens to have framebuffer graphics available to it. That way it potentially could serve up pdf and the such. I think a stock ttylinux could easily handle something like this although I'd have to work out the graphical output ... also utf-8 will require a bit of jiggery-pokery.

    Life is good,
    Maurice

    Sounds interesting. Last week I started updating ttylinux (https://github.com/andy5995/ttylinux/pull/1/files) but it's doubtful I'll continue with it on my own.

    Hey Andrew!

    continue with it on my own.

    It is far too much of a commitment for this old man. These days I am sticking to playing and helping out where I can. As for lfs, I doubt I could quit at this stage of the game. I got hooked around the same time I first started playing with ttylinux. For me they almost became the same thing.

    Life is good,
