[Daniel Axtens]

Hi Mao,

Thanks for that.

You are right, this should be split into two kernel issues.

I have opened:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1698700 - "pci:" prefix in 
bus ID
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1698706 - Quirk for vga 
card and bridge

I have subscribed you to these bugs. They include some updates to the
upstreaming process and I will keep them updated.

If it's alright with you I will close this bug as we've established it's
not a bug in X.

Regards,
Daniel

hi Danneil,

Those are translate from Huawei's reply mail:

The sever board have only this VGA PCI devices:
   19e5 Huawei Technologies Co., Ltd.
   1711 Hi1710 [iBMC Intelligent Management system chip w/VGA support]

Please check if this math to our D05 testing environment.

thanks,

[Zhanglei Mao]

hi Daniel,

It is very nice for your to provide a patch for it. For other PCI IDs, I
will check with Huawei team and back to you at next week.

By the way, what is status of first bug ( The busid reported by libdrm on
the arm64 system is "0007:a1:00.0"), has it been accept by upstram? Do you
have bug id for it? Actually, I think we can take both those 2 bugs back to
Huawei or Pearl team in case it is bugs from Kernel.

thanks,
Mao

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Daniel Axtens]

Hi Mao,

I have done more work on the HiSilicon board. I have talked with the SEG
team and our conclusion is that the hardware is not compliant with the
specification, but that it is appropriate to include a workaround in
software.

I have developed a patch that adds a workaround or 'quirk' to the kernel
specifically for the hisilicon graphics card and the hisilicon PCI
bridge. It tests for the card and the bridge on the development board. I
think it might be acceptable for upstream. With this, X
autoconfiguration works.

Please could you ask the HiSilicon people if there are other boards or
parts with different PCI IDs that should be included in this fixup?

Regards,
Daniel

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Zhanglei Mao]

This is mail thread we haved discussed about ARM to compliance for PCI
standard as other platform for x86, powerpc, ia64 etc. They key point
form Huawei guys are below:

"这部分ARM应该不能遵循，因为VGA
EN开辟的空间是给legacy的系统使用的，1M以下的空间划分是x86向前兼容性的做法，只有在CSM支持传统的系统才还这样做，在新的方案里能不用就不用，开辟IO空间对ARM来说更不合适，因为ARM在定义之初就没有IO这种资源类型。"

Translate: ARM would compliance this part of PCI stand (IO space, memory
address space), because VGA EN reserved spaces for only for legacy
system. The low space for 1M is to compatible X86, it only used from
CSM. In new implement, it need to avoid at best, to use IO space is also
not suitable for ARM because ARM didn't have any IO resource in its'
initial definitions.


thanks,
Mao

hi Danniel,

This forwarded mail are from Huawei guy which to say "PCI_BRIDGE_CTL_VGA"
are only used on X86 but not for AMR64. The English line was my translated

不清楚你们这个问题是基于什么平台提出的。

在ARM里没有用这个PCI_BRIDGE_CTL_VGA。这是x86的架构设计里用来分配IO和memory地址空间的。而ARM世界是没有IO
空间的概念的，至于memory空间，也是x86里为了支持legacy VGA而一直沿用的技术。具体信息可以看以下的内容。


Translating:

I don't know which platform was this request based on.

In the ARM,  PCI_BRIDGE_CTL_VGA was not used. This is a x86 architecture
design using as IO and Memory address space assign or allocation. In the
ARM word, there are no any IO space concepts,  for memory address space, it
was used space technology legacy VGA supports on X86. More details can be
found from below:

Thanks!

Agree with you that is something they need to fix. I have sent mail to
HiSilicon and their VGA card vendors and they replied some for confirming

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Daniel Axtens]

Hi Mao,

I have installed a version of the kernel which ignores the capabilities
of the PCI bridge when determining whether a device can be the boot
device. With this patched kernel, X starts without needing a config
file.

This confirms:
 - that the vga card is not marked as boot device because of the the PCI bridge 
that the VGA card sits behind.
 - not being marked as boot vga is what is causing X not to pick it up the card.

This is a debug patch only, and not a patch we will be able to get
upstream, so I think we will need to discuss with the HiSilicon people
why their hardware is behaving this way.

Regards,
Daniel

hi Daniel,

It is nice. I thought to upstream is the responsibility of HiSilicon/HWE
team. But If you can make it upstream, it will be out of all expecting and
very nice too.

thanks,
Mao

Hi Mao,

I have successfully verified that with the patched kernel and the Xorg
config, X starts fine.

Do you need assistance getting that patch upstream, or is that something
HiSilicon/the HWE team can do?

Daniel

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Daniel Axtens]

Hi Dann,

I have tried to boot the HiSilicon board with a zesty kernel (and with a
patched zesty kernel) and it boots, gets to the following, and then
hangs without displaying a prompt:

[9.900239] async_tx: api initialized (async)
[9.991929] Btrfs loaded, crc32c=crc32c-arm64-hw
[   55.474203] hidraw: raw HID events driver (C) Jiri Kosina
[   55.483000] usbcore: registered new interface driver usbhid
[   55.488571] usbhid: USB HID core driver
[ME] Fault detect start!
[ME] Fault detect start!

Is there anything different between the pearl kernels and the zesty
kernel that would make the prompt show up and/or avoid the hang?

Regards,
Daniel

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Daniel Axtens]

Hi Mao,

I have looked at the PCI setup a bit more closely: the VGA card is
behind a PCI bridge which does not advertise the PCI_BRIDGE_CTL_VGA
capability, so it is not being picked up by the kernel as the
default/boot card.

Is there anything special about the bridge or the hardware in this
regard?

Regards,
Daniel

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Daniel Axtens]

Hi,

I can get xorg working if I do these 2 things:

1) Edit memory with gdb to add "pci:" to bus id. This is what the kernel
patch should do. I will test the patch soon, I am just waiting for the
kernel to build.

2) Install this /etc/X11/xorg.conf:

Section "ServerFlags"
Option "AutoAddGPU" "off"
EndSection

Section "Device"
Identifier "dja"
Driver "modesetting"
BusID "pci:0007:161:0:0"
EndSection


This does 2 things:
 - AutoAddGPU prevents the card from falsely being marked as GPU. I am not yet 
fully sure why that is required.

 - The Device section then specifies the busid and driver specifically.
This forces the driver to be loaded correctly.

This Xorg configuration should not be required in the long term. There
are obviously still some bugs to be fixed. But, I wanted to let you know
that progress was being made and give you good news.

Attached is a screenshot of Xeyes over KVM.

Regards,
Daniel

For new kernel building, please note that is not a our general/stand
zesty, I though Dann use a another kernel source tree or use may patches
specified for D05 board. I am not familiar with it and please contact
with Dann too.

thanks,
Mao

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Daniel Axtens]

Hi,

On further investigation it turns out that one large difference between
my x86 system and the arm64 system is they way the vga arbiter is
operating in the kernel. This means that the vga card isn't labelled as
the "boot vga" card, which affects how it's picked up by X.

On the HiSilicon board, I'm seeing:

[0.815343] pci 0007:a1:00.0: vgaarb: VGA device added: 
decodes=io+mem,owns=none,locks=none
[0.815355] pci 0007:a1:00.0: vgaarb: bridge control possible
[0.815360] vgaarb: loaded

On an x86 vm I'm seeing:

[0.390696] vgaarb: setting as boot device: PCI::00:02.0
[0.391245] vgaarb: device added: 
PCI::00:02.0,decodes=io+mem,owns=io+mem,locks=none
[0.393421] vgaarb: loaded
[0.393811] vgaarb: bridge control possible :00:02.0

(The difference in the format is due to different kernel versions)

Looking at the kernel source, it looks like the owns= section is getting
blanked because of the bridge that the VGA card is sitting behind.

>From drivers/gpu/vga/vgaarb.c:

/* Mark that we "own" resources based on our enables, we will
 * clear that below if the bridge isn't forwarding
 */
pci_read_config_word(pdev, PCI_COMMAND, );
if (cmd & PCI_COMMAND_IO)
vgadev->owns |= VGA_RSRC_LEGACY_IO;
if (cmd & PCI_COMMAND_MEMORY)
vgadev->owns |= VGA_RSRC_LEGACY_MEM;

/* Check if VGA cycles can get down to us */
bus = pdev->bus;
while (bus) {
bridge = bus->self;
if (bridge) {
u16 l;

pci_read_config_word(bridge, PCI_BRIDGE_CONTROL, );
if (!(l & PCI_BRIDGE_CTL_VGA)) {
vgadev->owns = 0;
break;
}
}
bus = bus->parent;
}

/* Deal with VGA default device. Use first enabled one
 * by default if arch doesn't have it's own hook
 */
if (vga_default == NULL &&
((vgadev->owns & VGA_RSRC_LEGACY_MASK) == VGA_RSRC_LEGACY_MASK)) {
vgaarb_info(>dev, "setting as boot VGA device\n");
vga_set_default_device(pdev);

Perhaps X should be be picking up the card through PCI probing on arm64
rather than platform probing which seems to rely a bit on boot VGA
devices. I will check this. But first I just wanted to check the PCI
topology: is the card behind any unusual bridges or switches?

I can write some kernel code next week to find out specifically why this
isn't being picked up, but I thought I'd check for HW quirks first.

The latest zesty kernel works fine on the HiSilicon board, I'd suggest
patching that for your testing.

Daniel,

It is really good. For patch driver and new kernel buiding, I cc Dann on
the mail too, he is our engineer for this enablement project with
Hisilicon. This is pearl kernel was build by him too.

Dann,

Can you patch and build out a new kernel for us or help Daniel to build a
new testing kernel.

For the new kernel install, I should be able to set it up.

thanks,
Mao

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Daniel Axtens]

Ok, so I think part of the problem is that the kernel hibmc driver needs
to use a set_busid function from the drm core. I've simulated this
change in the debugger, and it seems to at least prevent the crash. (It
doesn't seem to be enough for the server to work, still working on
that.)

Here's a patch - we can discuss the best way to build and install it.

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Daniel Axtens]

OK, I have made some progress on this:

The busid reported by libdrm on the arm64 system is "0007:a1:00.0"
The busid reported by libdrm on a amd64 system is "pci::00:02.0"

The "pci:" prefix is missing on arm64. I think this leads to the
segfault on arm64 as X tests for the prefix.

This little C program below extracts the information and demonstrates
the difference.

I will follow up why this is happening.

Regards,
Daniel

#include 
#include 
#include "stdio.h"
#include 
#include 
#include 

int main() {
char *path="/dev/dri/card0";
drmSetVersion sv;
char *buf;
int fd;
int err = 0;

fd = open(path, O_RDWR, O_CLOEXEC);

sv.drm_di_major = 1;
sv.drm_di_minor = 4;
sv.drm_dd_major = -1;   /* Don't care */
sv.drm_dd_minor = -1;   /* Don't care */

err = drmSetInterfaceVersion(fd, );

buf = drmGetBusid(fd);
printf("busid: '%s'\n", buf);
drmFreeBusid(buf);
close(fd);
return (err == 0);
}

Hi Mao,

Yes, remote access would be the fastest way to debug this.

You can contact me by email - daniel.axt...@canonical.com.

hi Daniel,

If tt is more easy and save time for you. I can share my ssh remote access
to you for D05 testing environment, so you can directly patching and
testing over it.

thanks,
Mao

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Daniel Axtens]

Hi,

This is what I have figured out so far.

For some reason the initial probing done by the modesetting driver
fails. This is part of the platform device probing stage. This failure
means the device is not claimed by the modesetting driver as a 'regular'
screen. Instead it is claimed by the fbdev driver. The modesetting
driver then claims the platform device as a 'GPU' device. It shouldn't
do that: the GPU device init is what causes the crash.

What I am still trying to figure out is why the initial probing fails.
This is difficult to figure out from the core dump, so I have attached a
patch for xorg-server that should help. With this patch I should be able
to figure out what part of the probe doesn't go as expected.

Please let me know if you have any trouble applying the patch.

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Zhanglei Mao]

For the mainline kernel (general kernel from Ubuntu 16.04.02 AM64) was
not tested in case we are not supported for Hisilicon D05 board.

We also do some basic fbdev and modesetting testing on this kerenl by
pass Xserver, it seems works well and so we tend to think this is caused
by Xorg or driver of Xorg.

[Touch-packages] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

[Daniel Axtens]

Hi,

What happens if you remove the fb driver - uninstall the xserver-xorg-
video-fbdev package?

Also, I'm not sure what (if any) changes have been made in the kernel
version you're running - the 'pearl' version - but are you able to try
against a mainline kernel?

Regards,
Daniel

This final goal is "Ubuntu 16.04 support x-Window by modesetting 
(modesetting_drv.so) driver" 
 
Notes: From xserver source code，it only use modeset. For the display card 
hardware it is  a display controller without GPU，the call paths is 
xserver->modesetting_drv(userspace)->libdrm(userspace)->drm(kernel).

[Zhanglei Mao]

Pual Liu analyse for this bug, he provide a temporarily fix but it seems not 
works (no output in monitor)
---
Hi all,

I look deep into the problem and I'm not sure if it is the kernel issue or Xorg 
issue.
We might need to spend more time on this issue to tracing into the Xorg code.
The problem happens to the modesetting driver in Xorg. So if you remove 
/usr/lib/xorg/modules/drivers/modesetting_drv.so it will use the fbdev driver 
and the X will start.

When modesetting is there, we got a SIGSEGV. And it happens to a line
that shouldn't have any problem.

void 
RRSetChanged(ScreenPtr pScreen) 
{
   /* set changed bits on the master screen only */ 
   ScreenPtr master; 
   rrScrPriv(pScreen); 
   rrScrPrivPtr mastersp; 

   if (pScreen->isGPU) { 
   master = pScreen->current_master; 
   if (!master) 
   return; 
   mastersp = rrGetScrPriv(master); 
   } 
   else { 
   master = pScreen; 
   mastersp = pScrPriv; 
   } 

   mastersp->changed = TRUE;  // < CRASH here
}

So we need to figure out why mastersp disappeared.
There might be some race conditions here.
