Page fault in `linux_queue_work` when loading `i915kms`

Running c132a99 + recent -CURRENT, I get a page fault every time I kldload i915kms. I've created a gist of my core.txt file and am rebuilding vanilla c132a99 to ensure that the merge wasn't somehow to blame. Please let me know if there's any other information that would be helpful...

memory overwrites on Arrandale (AGP)

All the frame buffer attributes are the same in both 3.8 and 4.6 which is why it's very odd that bzero'ing it after mapping appears to overwrite many thread stacks causing the system to fail rather spectacularly.

Panic on i915kms load with AGP cards

(Opening this issue to track AGP support, which has not been upgraded yet. Reference: freebsd-X11 mailing list.)

There is a regression in AGP with the DRM 4.6 kernel. kldoad i915kms crashes the system with at least two Intel GMA processors:

G41 Express (desktop, EagleLake).
GM45 (mobile, Cantiga).

Those chips work very well with the 3.9 version of DRM.

FreeRDP panic

Hi!

I'm getting a repeatable panic when using FreeRDP to connect to a Windows guest after one or two minutes of what seems to be a stable connection:

I've tested with two quite different chips, an old G41 Express and a more recent i3-4030U Haswell.

Normal video operation is stable besides this issue.

Best regards,
Juan

P.S.: Updated kernel (05b8680) and packages from Matthew repository.

"MESA-LOADER: could not get PCI ID"

The hw.dri sysctl tree is missing -

The following need to be (re-)included:
https://github.com/freebsd/freebsd/blob/master/sys/dev/drm2/drm_sysctl.c
https://github.com/freebsd/freebsd/blob/master/sys/dev/drm2/drm_os_freebsd.c#L250-L251

drm46 needs to support debugfs

Periodically a ring will hang and i915_capture_error_state will report the following:

        DRM_INFO("GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.\n");
        DRM_INFO("Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel\n");
        DRM_INFO("drm/i915 developers can then reassign to the right component if it's not a kernel issue.\n");
        DRM_INFO("The gpu crash dump is required to analyze gpu hangs, so please always attach it.\n");
        DRM_INFO("GPU crash dump saved to /sys/class/drm/card%d/error\n", dev->primary->index);

Currently there is no way to retrieve that error information. This is a placeholder for tracking the addition of drm_debugfs and driver debugfs support.

QT5 redraw problems

When a qt5 window is partially covered it doesn't get redrawn when revealed.

I'm able to reliably trigger this by going to 'about:support' in Firefox 46.0 with SNA. Switching back to UXA and I can get there.

Very Slow Keyboard Input On Haswell

$ sysctl hw.model
hw.model: Intel(R) Core(TM) i7-4600U CPU @ 2.10GHz
$ uname -a
FreeBSD pier 11.0-ALPHA5 FreeBSD 11.0-ALPHA5 #6 a76e358(drm-next-4.6)-dirty: Fri Jul 1 20:09:29 PDT 2016 root@srd0009:/usr/obj/usr/home/pwright/git/freebsd-base-graphics/sys/GENERIC amd64

When I load the i915kms module on this platform I get very slow keyboard input. The system is usable, but it takes several seconds for keyboard touches to update on the console. When I startx (doing "Xorg -configure") and then exit X keyboard inputs update as expected.

External display issues (Skylake)

I just tried plugging my Skylake laptop into an external display with 71faa5b. The xrandr support now seems to work well: I can change the display geometries and work off of the two displays. Two issues:

the driver does not detect when I unplug from the external display (I need to manually deactivate it) and
there are two horizontal lines of artifacts on my internal display after I disconnect from the external display.

Other than that, it's a definite improvement!

linuxulator core dumps useless - need support for linux format cores

FreeBSD dumps FreeBSD style cores for Linux applications - making them unusable by a debugger on linux or FreeBSD.

Do load time updating of intrinsics

On Linux a call to the clflushopt instruction will be replaced at boot / load time by the older clflush. There's no reason that linuxkpi consumers can't enjoy the same benefit.

linux_recvfrom doesn't support ipv6

google chromium causes kernel panic on Haswell

Start X with SNA enabled using cwm as my window manager. i then start xterm and from there launch google chromium. This results in a kernel panic with the following backtrace. Looks like I need to rebuild my kernel with optimization flags disabled but hopefully this is helpful.

System lock under MacBookPro 2015

FreeBSD mbp.gddsn.org.cn 11.0-ALPHA1 FreeBSD 11.0-ALPHA1 #12 fc26d6b(drm-next-4.6)-dirty: Thu Jun 16 06:17:18 CST 2016 [email protected]:/usr/obj/home/hwh/git/freebsd-base-graphics/sys/MACBOOK amd64

Sometime system lock:

No page flip (vsync) callback

User program hangs at select() on /dev/dri/card0.
Could possible be solved by adding current task to the queue in poll.h

static inline void
poll_wait(struct linux_file *filp, wait_queue_head_t *wait_address, poll_table *p)
{    
    selrecord(curthread, &filp->f_selinfo); 
}

I tried adding

    DECLARE_WAITQUEUE(entry, current);
    add_wait_queue(wait_address, &entry);
    schedule();
    remove_wait_queue(wait_address, &entry);

but all I get is a hung program that can not be killed... Need someone with more knowledge about this...

ValleyView: screen corruption after starting "chrome"

Xorg and KDE4 run well; but after running "chrome" screen corruption occurs. Afterwards, text of the KDE menus seems to be okay.

Here's my "/var/log/messages":

valleyview.drm.log.txt

Tried using "xf86-intel-video" in versions 2.21.15_9 and the manually built 2.99.917. No difference. AccelMethod "SNA" is unusable in 2.99.917

Switching between Xorg and console works well - even after corruption has started. My laptop: "Lenovo G50-30" with
vgapci0@pci0:0:2:0: class=0x030000 card=0x381817aa chip=0x0f318086 rev=0x0e hdr=0x00 vendor = 'Intel Corporation' device = 'Atom Processor Z36xxx/Z37xxx Series Graphics & Display' class = display subclass = VGA
and
vgapci1@pci0:1:0:0: class=0x030200 card=0x381817aa chip=0x114010de rev=0xa1 hdr=0x00 vendor = 'NVIDIA Corporation' device = 'GF117M [GeForce 610M/710M/810M/820M / GT 620M/625M/630M/720M]' class = display subclass = 3D
(Optimus system)

HDMI hotplug doesn't work correctly

adding an HDMI connection at runtime is recognized but if done after driver load will not result in the display being correctly plumbed in for X or the console.

[drm:intel_hpd_irq_storm_detect] Received HPD interrupt on PIN 5 - cnt: 0

Problem on mode switch (Skylake)

After leaving my screen closed for awhile, X often fails to resume with an error such as this:

display goes grey/black on starting X using 2016060520 img

reproduce

gears strange behavior with MacBookPro 2015

While running gears, move mouse, gears look fast:
217 frames in 5.003 seconds = 43.374 FPS
311 frames in 5.016 seconds = 62.002 FPS
311 frames in 5.020 seconds = 61.952 FPS
255 frames in 5.212 seconds = 48.926 FPS

If stop moving mouse, gears look very slow:
29 frames in 5.053 seconds = 5.739 FPS
23 frames in 5.530 seconds = 4.159 FPS
19 frames in 5.004 seconds = 3.797 FPS
26 frames in 5.006 seconds = 5.194 FPS

Artifact when starting X on Intel® HD Graphics 4400

hw.model: Intel(R) Core(TM) i7-4600U CPU @ 2.10GHz

After loading the drm2 and i915kms kernel modules I generate an xorg.conf using "X --configure". This config allows me to start xfce4 but there are artifacts once xfce loads. Specifically there is no text in the login dialog. Once I click on the dialog the system kernel panics at:

dev/drm2/drm_modeset_lock.c:336

I will post a backtrace and the Xorg once I have the system back online.

Xorg Unable To Find fbdev

CPU/GPU: Intel® HD Graphics 4400

I am able to boot via the May-24 CFT disk image. Primary laptop display is unreadable. But I am able to log in as root, kldload drm2 and once i load the i915kms module the display resets and I am able to see text with out issue.

I then attempt to start X which fails with the following error:
619.959 LoadModule: "fbdev"
619.960 Warning, couldn't open module fbdev
619.960 UnloadModule: "fbdev"
619.960 Unloading fbdev
619.960 Failed to load module "fbdev" (module does not exist, 0)

I've attached the full output of Xorg.0.log from this system for further analysis. I have also attached the full /var/log/messages file which contains some debug output from drivers loading etc.

Xorg.0.log.txt
messages.txt

I also was able to generate a kernel panic on this configuration but it looks unusable, so that may be an unrelated bug.

PC-BSD 11.0-CURRENTJUNE2016 works when limited to VESA but seems to panic with any attempt to use i915.

(I can not get a core dump, but I do have photographs showing i915_driver_load… in each backtrace. If/when I get the photographs off my phone, I'll add them to this issue.)

Panic in i915kms on power mode change (HD 4400)

With a Haswell (HD 4400) GPU laptop, changing the power mode (plugging or unplugging the power cord) leads to instant panic, while with the drm-next-3.9 branch, switching AC/battery modifies backlight value up and down without issues.

To reproduce:

# kldload drm2 
# sysctl dev.drm.skip_ddb=1 
# kldload i915kms

[plug / unplug the power cord (the result is exactly the same)]

panic: IMPLEMENT ME
…then the backtrace (picture).
