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.

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. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1691991 Title: Xorg Segmentation fault on Hisilicon D05 board (arm64) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1691991/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

hi Daniel, Thank you very much for you mail and I am very glad you are debugging this reported bug. Can you please provide me a bit more guide or guide link which I can apply this patch and compile out the newly testing Xorg? Sorry I am not so familiar with our building/compile tools. thanks, Mao On Wed, May 31, 2017 at 3:07 PM, Daniel Axtens wrote: > Hi, > > This is what I have figured out so far. > > For some reason the initial probing done by the modesetting driver > fails.

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 On Thu, Jun 1, 2017 at 7:56 PM, Daniel Axtens wrote: > 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.

hi Daniel, 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 and understand questions or our requests. I will push them again. thanks, Mao On Thu, Jun 8, 2017 at 8:41 AM, Daniel Axtens wrote: > 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.

[Ubuntu-x-swat] [Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)
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 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1691991 Title: Xorg Segmentation fault on Hisilicon D05 board (arm64) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1691991/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

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 On Fri, Jun 16, 2017 at 11:46 AM, Daniel Axtens wrote: > Hi Mao, > > I have done more work on the HiSilicon board.

[Ubuntu-x-swat] [Bug 2024520] [NEW] Moorethread GPU driver support on Xorg
Public bug reported: During our test for moorethreads GPU on Ubuntu 20.04 with lightdm+gnome+xorg desktop environment, we found that it can load DDX with mtgpu.drv.so, but during screen locking, the lightdm will start a new Xorg to display a greeter, this new Xorg would match a driver of modesettings_drv.sio instead of a correctly one mtgpu_drv.so. After debuging, we found the root cause is that xf86VideoPtrToDriverList function of Xorg is absent support for moorethreads GPU, there is a patch to fix this and hope it can be merged to Ubuntu release (20.04 LTS and following). ** Affects: xorg (Ubuntu) Importance: Undecided Status: New ** Attachment added: "mt_pci_vendor.patch" https://bugs.launchpad.net/bugs/2024520/+attachment/5681079/+files/mt_pci_vendor.patch -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2024520 Title: Moorethread GPU driver support on Xorg To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/2024520/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
