4.19 kernel 64 bit support - please report issues here

[sakaki]

With the latest kernel (4.19.23-v8-5eeff139ea91-bis+) fkms seems a lot better, coming up without crashing now.

(non-f) kms working fine on Gentoo Xfce4, except when compositing is on, then, the system seems to 'stutter' every 15 seconds or so, for around a second each time. Moving a window around on the desktop in a circular pattern is sufficient to cause this. With compositing off there is no issue (even with full-frame video). No issue either way under 4.14.y. Running mesa-19.0.0_rc4, 64-bit userland.

[sakaki]

Apologies, slightly OT, but I was looking at building an updated version of raspberrypi/userland for the Gentoo image yesterday, and a number of the components (MMAL) etc are still masked out (by an ARM64 define). I tried compiling them anyway, since now using a 4.19.y kernel, and got a number of errors, but most seemed like they could be worked through easily enough (ints becoming longer when compiled under aarch64, then getting passed into printf with the wrong qualifier, etc.) plus a few others that probably would require a little more thought.

So my question is: is it worth me wading through these to fix them for aarch64 (given that the kernel now seems to play nicely with most MMAL stuff from a 32-bit userland perspective), or is this something that is a near-term plan at RPF anyway? Reason being, is I'd like to release a gentoo-on-rpi3-64bit image supporting MMAL etc.

Or perhaps there are other things that still need sorting at a deeper level (zero-copy was I think mentioned at one point?) so I should hold off for now?

Thanks,

sakaki

There is no 64bit userspace MMAL support.
I've added v4l2 drivers that can make use of MMAL for video codes and resize, and then the v4l2 app can be either 32 or 64 bit.

It may be possible to make MMAL userspace work in a 64bit environment, but that hasn't been done yet. There are pointers within the structures that mean we have an issue should a 32bit application be run with a 64bit MMAL core, and there's no easy way to deal with it.
64bit apps to a 64bit MMAL core should be possible to work, but needs some tweaks in the core.

Hi 6by9,

appreciate the V4L2 stuff, which I think will work well incidentally, but when you say:

There are pointers within the structures that mean we have an issue should a 32bit application be run with a 64bit MMAL core, and there's no easy way to deal with it.

I'm not sure I understand: you earlier said:

64 bit kernel under a 32 bit raspbian is working fine for me, and I'm in the process of fixing up the bits of the kernel that don't work.

All the Mmal and IL apps I've tried still work with that, as the buffers passed from the 32bit app still map correctly onto the Gpu versions of those structures. The 32 bit mmal/IL framework stuff in userspace make the correct mappings for transferring data. (The one bit that really doesn't work at the moment is mmal zero copy as the vcsm driver doesn't work on aarch64). Build a 64 bit userspace version of those framework libraries and I'd expect it to fail.

Or am I getting my nomenclature wires crossed here? By "64bit MMAL core" in your first post, are you referring to the userspace MMAL libraries being 64-bit, rather than any kernel support they may rely on? Or to put another way, under 4.19.y is it the case currently that:

• 32-bit kernel, 32-bit MMAL userspace library: works (stock system)
• 64-bit kernel, 32-bit MMAL userspace library: works (per your second post, above)
• 64-bit kernel, 64-bit MMAL userspace library: doesn't work, due to pointer issues?

Best, sakaki

• 32-bit kernel, 32-bit MMAL userspace library: works (stock system)

• 64-bit kernel, 64-bit MMAL userspace library: doesn't work, due to pointer issues?

Exactly that.
libmmal_vc_client is the problem, and partly with the defined RPC messages.

An application will pass in a MMAL_BUFFER_HEADER_T *. If you have a 64bit libmmal_vc_client, then it will be casting the structure with 64 bit pointers.
I'm not clear on how that is going to work should you be running a 32bit application on your otherwise 64bit system. Can we have both 32 and 64bit versions of libmmal_vc_client present on the same system so that they'll both work correctly on parameter sizings? Is selection of which one to use automagical, or something else required. I'm looking for the equivalent of all the compat ioctls in the kernel.

The RPC issue is places like https://github.com/raspberrypi/userland ... sgs.h#L155 where a client handle is passed to VideoCore and subsequently returned on event or buffer callbacks.
Currently a 32bit pointer to the component is stored in that field, and that won't work for a 64bit pointer. This can be solved fairly easily with a lookup table within the framework, and that is exactly what the V4L2 drivers are doing with an IDR within the vchiq-mmal framework.

What issues are you seeing with fkms? I thought I'd got to the bottom of the issue on fkms and it is working fine for me.
Buster appears to have a broken Mesa at the moment though, so x is giving me issues. Just another thing to investigate.

Hoping Buster will be updated to Mesa 18.3.4. I saw a couple VC4 issues fixed in x.x.3 & x.x.4 which might help.

yep, had 18.3.2 issue and update to 18.3.3 solved.

I just saw that buster got bumped to 18.3.4 which should help even more.

[6by9]

I just saw that buster got bumped to 18.3.4 which should help even more.

Tried it on Friday, and yes x is working again with buster and 18.3.4. Onwards and upwards.

And if they manage to squeeze 1.20.4 in under the wire, we'll be better off as well I would surmise.

Sounds great, thank you to all! – Any workaround for the dreaded lack of libcurl3 in Buster which is a hard dependency for Mathematica's Wolfram-Engine?

Until wolfram is updated for Buster, you'll either have to remove it or deal with held back packages.

Here are the steps I did to compile the 4.19.y kernel (natively on a 64-bit little-endian pi):

• make bcmrpi3_defconfig
• make nconfig
  
  in "Kernel Features" I clicked on

  Code: Select all

              [*] Build big-endian kernel
  

• make -j4 Image V=1
• make -j4 modules V=1
• make -j4 dtbs V=1
• make modules_install
• make dtbs_install

All the above steps completed without problems.

As next I copied arch/arm64/boot/Image and the bcm2710-rpi-3-b.dtb files to the usual place into /boot/.

Then powering on the pi resulted in nothing (blank screen), i.e. the green LED blinked the pattern

___|_|_|_|____|_|_|_|___ ...

which I interpreted as the standard bootloader not understanding what to do with "kernel8.img".

To continue I renamed kernel8.img into kernel8_be.img, bcm2710-rpi-3-b.dtb into bcm2710-rpi-3-b_be.dtb, copied u-boot.img into kernel8.img and powered the pi on again, booted the big-endian kernel manually and then the logs above appeared onto remote kermit-connected UART console.

As a note, to verify raspberry-pi's big-endian support I updated few bzt's bare-metal tutorial examples into big-endian and they all work fine, so the kernel panic above at first sight seems to be only due to some firmware blob or whatever which either cannot be found or is not compatible. Unfortunately if I disable firmware support in 'make nconfig', then the kernel doesn't even get that far, the above log file doesn't show anything after "Starting kernel ...".

It is true that arm big-endian support in linux kernel and gcc is quite solid, and even on raspberry pi we get all the cores up and running, but it looks like there are few minor issues which are hardly raspberry or broadcom closed-source-related:

• The standard bootloader refuses to load kernel8.img if it appears to be big-endian linux kernel (its apparently no problem to load a big-endian bare-metal binary). According to "linux/Documentation/arm64/booting.txt" the big-endian kernel image I tried has this header:

      res5  = 0x00000000
  

  Is this correct?
• The firmware dependencies: how to get rid of them? For the curious it is enough to run linux in a minimalistic mode, only supporting hardware having open-sourced drivers (mmc, ethernet, etc. etc.). Its no problem not to have proprietary hardware accelerated OpenGL or H264 codec or whatever support. Even without a framebuffer (i.e. working over ethernet or UART-connected console) the pi is a great platform.

Is there any obvious method to complete the boot above?

Here are the steps I did to compile the 4.19.y kernel (natively on a 64-bit little-endian pi):

• make bcmrpi3_defconfig
• make nconfig
  
  in "Kernel Features" I clicked on

  Code: Select all

              [*] Build big-endian kernel
  

Sorry, big-endian support is not something I'm going to invest time in, and I doubt it has ever worked on any Pi kernel, whether 32 or 64bit.

The GPU is little-endian, and the mailbox service is not set up for mixed endian-ness. That explains the errors such as

Code: Select all

[    0.303956] raspberrypi-firmware soc:firmware: Request 0x00048020 returned status 0x01000080
[    0.304022] brcmvirt-gpio soc:virtgpio: Failed to set gpiovirtbuf, trying to get err:ffffffea
[    0.304160] raspberrypi-firmware soc:firmware: Request 0x00040010 returned status 0x01000080
[    0.304207] brcmvirt-gpio soc:virtgpio: Failed to get gpiovirtbuf

Fix up the raspberrypi-firmware driver to do all the necessary endian conversions and you may have a hope, but as it is you have no frame buffer, nor much power management.
I suspect that the MMC driver is then also not doing correct endian conversions, so whilst the bootloader can load kernel8.img for you, the kernel will then fail when it tries to load modules or configuration. That would then explain the kernel being unable to mount the root file system (the cause of the kernel panic).

What is your real-life use case for switching to big-endian? It seems like setting options for the sake of setting options.

Hi all,

I have updated linux kernel via rpi-update and installed gstreamer 1.14.4. Now get-inspect-1.0 sees v4l2h264enc as available plugin. Is it enough to use zero-copy video encoding using v4l2 interface or I should compile kernel with some specific flags/configs?

You've posted on a thread for 64-bit 4.19 kernel support, but have used rpi-update which will get a 32-bit kernel. Please try to keep topics separate. In this case the comments apply equally to both.

No kernel changes required if running 4.19.
Zero copy exactly where? The V4L2 components support dmabufs, but whatever it links to needs to support them too in order for GStreamer not to have to copy the data around.
GStreamer may automatically select dma-bufs if the components support it, but there are manual controls with output-io-mode and capture-io-mode. The terminology sucks here, but comes from the V4L2 level. output-io-mode controls the input to the codec, and capture-io-mode controls the output. 4 is dmabuf export, 5 is dmabuf import.

Dear all,

I would like to kindly ask you for a help.
I tried to take advantage of hardware acceleration exposed via v4l2 present in kernel 4.19 via Gstreamer according to web page:
https://github.com/sakaki-/gentoo-on-rp ... era-Module

I ran this command:
gst-launch-1.0 -e -vvv filesrc location=test.mkv ! matroskademux ! \
queue ! h264parse ! v4l2h264dec capture-io-mode=4 ! \
glimagesink

But Gstreamer consumes 95% of CPU usage.

The same with:
ffplay -vcodec h264_v4l2m2m -i test.mkv

Could anyone explain me this issue? Is it really hardware accelerated? That all is running on top of X11 with latest Sakaki Gentoo image.

Moreover, according to Sakaki, the OpenGL acceleration is able tto run at this speed mentioned on his webpage:
"On my RPi3 at least, a glxgears score of ~1000fps can be obtained on an unloaded system (~400fps on a loaded desktop) - in the same ballbark as the non-free Raspbian driver. "

Could anyone please give me a hint how to achieve this?

Thank you
Best regards,
Ivo

On Raspbian with Gstreamer 1.14.4 or 1.16 compiled. Using v4l2h264dec does not work at all.
Replacing v4l2h264dec with omxh264dec works file.

Raspbian does not use a 64 bit kernel, therefore this thread is totally the wrong place to be reporting any issues.
You also haven't provided the GStreamer pipe that you are trying to use there, and I'm not going to try guessing, nor making a rash assumption that it is the same as your previous post related to Gentoo.

glimagesink support relies significantly on which graphics option you are using, so is it legacy, Fake KMS, or Full KMS?

ffmpeg/ffplay does not work directly as it does some daft things over V4L2 selections. IIRC sakaki added my hacked patches for ffmpeg to Gentoo, but I doubt they are in Raspbian.

[horai]

Ok, do you recommend to start a new thread?

Anyway, I mentioned the pipeline before, so once more:
gst-launch-1.0 -e -vvv filesrc location=test.mkv ! matroskademux ! \
queue ! h264parse ! v4l2h264dec capture-io-mode=4 ! \
glimagesink

I used Raspbian 32 bit version with kernel obtained from rpi-update, compiled my own Gstreamer 1.14.4 as well as 1.16. I guess that one is 32 bit.
It seems to show some kind sign of v4l2 codecs in /dev/video10 /dev/video11 /dev/video12, but Gstreamer reports v4l2h264dec only and I assumed it should be among element list as something like v4l2video10dec.

[horai]

In Raspbian I am using KMS, I just triend Gentoo (it uses FKMS) because in Raspbian, I was not able to run the pipeline with v4l2h264dec capture-io-mode=4, only capture-io-mode=2 was possible to run and that is not dmabuf. OMX works fine

[horai]

Dear sir,

what do you mean by rash assumption? You mean trying to run something that is clearly written that is working in Gentoo?
64 bit?
This is a Sakaki statement:
"Leveraging recently improved 64-bit support in the official Raspberry Pi kernel tree, the image supports"

Please start a new thread. I suspect your use of glimagesink is the issue. If using any flavour of KMS then please try only booting to the console and using kmssink instead. GL is almost always a huge overhead.

/dev/video10 is video decode and should support H264, MPEG4, H263, MJPEG, by default, and MPEG2 and VC1 if you've bought the licence.
/dev/video11 is video encode and should support H264 and MJPEG.
/dev/video12 is image conversion (it wraps the ISP component), and supports a large number of input and output formats. GStreamer wraps it to v4l2transform (IIRC)

the first instance of any codec will omit the video node number, so you should get v4l2convert, v4l2h264dec, and v4l2h264enc, etc, unless there are multiple V4L2 M2M devices that can decode that format.

[horai]

Just to make it clear, I want to run v4l2h264dec with dmabuf=4 on Raspbian, that means 32 bit system. Since I did not find much information about using v4l2h264dec on Raspbian, I triend Gentoo (64bit) because on Raspberry Gentoo image documentation, it is written that it can run v4l2 codecs with taking advantage of VC4 h264 GPU acceleration using Gstreamer, but I was not successfull

This is my last response to this thread as it is not related specifically to 64 bit kernel support.

It would have been a rash assumption that you are using the same GStreamer command line on Raspbian as you did on Gentoo. I can only work with the information given.
Nothing to do with Sakaki's statement.

Has anyone managed to build and boot a 64-bit kernel for the Pi4 yet? I currently build my own 64-bit kernel from the raspberrypi/linux github repo, to use with 64-bit arch Linux arm userland on a 3B+. I’m hoping to migrate that system over to the Pi4 when my order eventually arrives, but I’ve seen on the github issues page that there have been a few boot issues with the 64-bit kernel and the pi folks are saying the pi 4 is not 64-bit ready.

@Sakaki Do you plan on getting hold of a Pi 4 and making an autobuild project based on the bcm2711_defconfig ? I always find your project so useful on arch when I’m not building the kernel myself

Hi jimbojones,

yes, I have a couple of Pi4s now, and have also cross-compiled the current 4.19.y bcm2711_defconfig kernel successfully. It's not really ready for prime time yet (as you note), but once these glitches are ironed out upstream then yes, I do intend to provide a public autobuild for this.

Best, sakaki
