Description Bob Raitz 2013-12-17 08:28:07 UTC 
Created attachment 118781 [details]
.config of latest 3.12 kernel exhibiting the above-mentioned issue.

I am running Gentoo Linux on an Intel-based laptop. With any 3.12.x kernel installed, the boot process will begin normally, and then, when there would normally be a shift in text size as the intelfb was modeset with, "append="i915.modeset=1" using lilo as a boot loader, all I get is a blank screen. The backlight is lit. If I allow approximately two minutes for the boot cycle to end, then log in, then hit the up arrow to startx, X does start. If I then exit X, then I am returned to a CLI of the size I am used to under normal circumstances.

In all other kernel versions, the intelfb would then start and go to native screen size: (1200x800). I could then either work in CLI from that point, or X.

I have read the document* that is supplied in the kernel. Using nomodeset will allow me to boot to a distorted CLI, and I cannot then start X. 

This is not so much a bug report as it is a way to find out how to get my intelfb to operate as it has operated since KMS became mandatory. If there is something I can add to /etc/lilo.conf that will make it work, I'd really like to know what those magic words are so I can update to the latest kernel sources.

I have tried enabling the vesafb as is suggested, but once modesetting is turned on, the screen does its disappearing act. Once again, if I can log in and start X, things will be back to normal.

*Intel 830M/845G/852GM/855GM/865G/915G/945G Framebuffer driver
================================================================

A. Introduction
	This is a framebuffer driver for various Intel 8xx/9xx compatible
graphics devices.  These would include:

	Intel 830M
	Intel 845G
	Intel 852GM
	Intel 855GM
	Intel 865G
	Intel 915G
	Intel 915GM
	Intel 945G
	Intel 945GM
	Intel 945GME
	Intel 965G
	Intel 965GM

B.  List of available options

   a. "video=intelfb"
	enables the intelfb driver

	Recommendation: required

   b. "mode=<xres>x<yres>[-<bpp>][@<refresh>]"
	select mode

	Recommendation: user preference
	(default = 1024x768-32@70)

   c. "vram=<value>"
	select amount of system RAM in MB to allocate for the video memory
	if not enough RAM was already allocated by the BIOS.

	Recommendation: 1 - 4 MB.
	(default = 4 MB)

   d. "voffset=<value>"
        select at what offset in MB of the logical memory to allocate the
	framebuffer memory.  The intent is to avoid the memory blocks
	used by standard graphics applications (XFree86). Depending on your
        usage, adjust the value up or down, (0 for maximum usage, 63/127 MB
        for the least amount).  Note, an arbitrary setting may conflict
        with XFree86.

	Recommendation: do not set
	(default = 48 MB)

   e. "accel"
	enable text acceleration.  This can be enabled/reenabled anytime
	by using 'fbset -accel true/false'.

	Recommendation: enable
	(default = set)

   f. "hwcursor"
	enable cursor acceleration.

	Recommendation: enable
	(default = set)

   g. "mtrr"
	enable MTRR.  This allows data transfers to the framebuffer memory
	to occur in bursts which can significantly increase performance.
	Not very helpful with the intel chips because of 'shared memory'.

	Recommendation: set
	(default = set)

   h. "fixed"
	disable mode switching.

	Recommendation: do not set
	(default = not set)

   The binary parameters can be unset with a "no" prefix, example "noaccel".
   The default parameter (not named) is the mode.

C. Kernel booting

Separate each option/option-pair by commas (,) and the option from its value
with an equals sign (=) as in the following:

video=intelfb:option1,option2=value2

Sample Usage
------------

In /etc/lilo.conf, add the line:

append="video=intelfb:mode=800x600-32@75,accel,hwcursor,vram=8"

This will initialize the framebuffer to 800x600 at 32bpp and 75Hz. The
framebuffer will use 8 MB of System RAM. hw acceleration of text and cursor
will be enabled.

Remarks
-------

If setting this parameter doesn't work (you stay in a 80x25 text-mode),
you might need to set the "vga=<mode>" parameter too - see vesafb.txt
in this directory.


D.  Module options

	The module parameters are essentially similar to the kernel
parameters. The main difference is that you need to include a Boolean value
(1 for TRUE, and 0 for FALSE) for those options which don't need a value.

Example, to enable MTRR, include "mtrr=1".

Sample Usage
------------

Using the same setup as described above, load the module like this:

	modprobe intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1

Or just add the following to a configuration file in /etc/modprobe.d/

	options intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1

and just do a

	modprobe intelfb

There is a forum thread on this as well in the Gentoo forums. Another has claimed this issue remains with the 3.12.5 kernel. I haven't compiled that version yet myself, but I don't think the results will be radically different. I suppose I could just for giggles. Anyway, here's the Gentoo forum thread:

IIUC you had this working in 3.11 - care to bisect where this was broken?
Comment 4 Bob Raitz 2013-12-19 07:32:26 UTC 
IIUC?

> intelfb is basically historic only

I'm not really sure what that has to do with my issue. All I want to know is how to update to the latest "stable" kernel sources, and be able to use my computer like I do with 3.11.10, or any of the other kernel versions that have worked properly up to this point in time.
Comment 6 Daniel Vetter 2013-12-19 08:16:40 UTC 
The intelfb driver is abandonware. If you do the bisect we might be able to fix something (since we can put blame on whomever broke it) otherwise there's not much really that will happen.
Comment 7 Alan 2013-12-19 08:20:30 UTC 
Most likely the simplefb bug in which case it ought to start working again once those fixes are in.

Really though I would switch to the i915 driver

Comment 9 David Herrmann 2013-12-19 10:40:16 UTC 
The config has X86_SYSFB not set, so this is unlikely to be related to the simplefb/sysfb stuff.

TBH, I also don't understand the bug exactly. A kernel-log would help narrowing it down.

Hm, but looking at the gentoo-bugreport you have X86_SYSFB enabled. So can you either try applying this patch:
  http://thread.gmane.org/gmane.linux.kernel/1616367/focus=1616583
..or disable CONFIG_X86_SYSFB.
Comment 10 Bob Raitz 2013-12-19 22:44:11 UTC 
I detect that I might not have been clear. Let me re-iterate:

1. This machine boots to a CLI. It does not boot directly to X.

2. What is or isn't abandonware is immaterial as far as I can tell. I am using the latest X video drivers available for intel. All I care about is that I can see my boot process, then be able to log in, then be able to start X, like I have been able to do from the time that KMS became mandatory; like I am able to boot with every kernel version up to 3.11.10.

3. X starts and runs normally if I wait for the boot process to finish, log in, then hit the up arrow key to bring up startx (blindly). At that point X starts and runs normally. Upon exiting X, the CLI, which did NOT exist before starting X suddenly exists upon exit from X.

4. The .config file that I sent was originally from a 3.11.0 .config that worked properly. Any deviation from that .config would be due to make oldconfig asking for certain things to be updated.

I will try the patch, but I am a bit gobsmacked that something of this nature would be allowed to be called stable, when it has yet to be functional, much less stable, on my machine and others, and we're already at 3.12.5. I don't expect perfection. I do expect minimal operation.
Comment 11 Bob Raitz 2013-12-19 23:53:40 UTC 
Patch was worthless. 

In order to clear up any remaining misunderstandings, as to what is or isn't abandonware, I offer my /etc/lilo.conf file so that you might see that I have tried more than one thing to get this kernel to run the framebuffer. All attempts have been fruitless.

Comment 12 Jani Nikula 2013-12-20 12:02:18 UTC 
This isn't even about intelfb as far as I can tell. You don't have it enabled in your config, and instead you have the i915 enabled. Which is good.

Please provide the dmesg from early boot to the problem, with drm.debug=0xe module parameter set.

If you want to speed up the process, please git bisect from 3.11 to 3.12 to find out what broke your setup.
Comment 13 Bob Raitz 2013-12-21 11:36:19 UTC 
Okay. This first dmesg is from 3.11.10. I'll reboot, and then send the 3.12.2 dmesg.

Firstly, this appears to only be an issue with x86. I have an amd64 with an intel chipset that works fine with that version.

Please attach the dmesg with drm.debug=0xe. It will dig up more info.
Comment 20 Bob Raitz 2014-01-11 09:40:18 UTC 
Explain how to do it, and I will.

> Explain how to do it, and I will.

Probably the easiest and least intrusive would be to add 'drm.debug=0xe' to your kernel command line when booting. If you're using grub, you can hit 'e' to edit the commands before actually booting the kernel. Find the linux boot line, add that parameter, without the single quotes, to the end. This way, the setting won't be persistent; if you need it again, you have to repeat this at each boot.

Once booted, run dmesg and make sure the line with "Kernel command line" includes the parameter, and attach the output. Thanks.

dmesg using drm.debug=0xe with warm reboot.

As an added bit of information, I did a warm reboot (three-finger salute), I noted that the frame buffer didn't reinitialize. Doing a full reboot will allow the frame buffer to work properly. Doing a diff on the results is interesting.
Comment 24 Bob Raitz 2014-01-28 10:41:18 UTC 
So, has any of this been helpful to any degree? I'm just wondering.
Comment 25 Bob Raitz 2014-03-17 17:02:27 UTC 
As an FYI, another user in a Gentoo thread devoted to this issue came up with the most likely culprit: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a09e9a7a4b907f2dfa9bdb2b98a1828ab4b340b2

Considering the amount of changes in that code, and the fact that the issues I and others are having are directly related to this, I find it silly that I would have to bisect the code when this glaring batch of mess is clearly a good source of where the issues lie.

Now, the question is, are you going to fix it now that there is a commit on which to hang all the numerous issues with i915? I sure hope so, as the death of XP will render this machine completely obsolete if you can't fix this glaring issue.

Yes, the drm merge for 3.12, i.e. everything that changed in gpu/drm land for 3.12 is there. Hardly something you could pinpoint as a culprit.

Please try v3.14-rc7 or drm-intel-nightly branch from [1].

Comment 27 Bob Raitz 2014-03-17 23:20:34 UTC 
On a scale from 0 to 1, 3.14-rc7 was a solid 0, exhibiting all of the things I stated originally in the bug. Do you have a lilo incantation that will make that work properly? If so, please tell me.

append="i915.modeset=1" does not work. Is there one that does?

ff11: my dmesg using drm debug workaround VGA

This is my dmesg using drm.debug=0xe with one workaround for this bug: plugin some monitor on VGA input
Comment 31 ff11 2014-03-18 02:18:19 UTC 
Because plugin some monitor on VGA input workaround this bug for me, I'm using the kernel parameter "video=VGA-1:e".

* This bug happen to me since the 3.12 to 3.13.6 for what I have tested.

* When I boot without VGA input or force VGA enable, it's just some black screen. But is not the brightness, I have used setpci direct on the hardware for set it to max on boot script, and the result is just high brightness black screen.

* When I boot with VGA input or force VGA enable (kernel parameter "video=VGA-1:e") the LVDS work again (not black screen anymore).

* When I boot without VGA input or force VGA enable, it's just some black screen. But if I plugin some VGA monitor, the screen go back to the normal at this moment (not need to reboot)

I posted some logs. The discussion on gentoo forum is in:
https://forums.gentoo.org/viewtopic-t-977360.html

If you need more information, just ask.

Ok! But I will need of time to do it. And I don't have at the moment (I came with the workaround because this). If someone else on gentoo forum, want to do it, then I will report back the result.

Probably 1 month or 2 (maybe 3), if nobody speed it up.

For me, this bug came from attend a new demand hardware, without much preoccupation or test with the old ones. At least for me, it's all around this:

Bob, helping out with the bisect will move this forward. Google will point you at some good howtos (kernel bisect + your distro's name is a good start). Ranting and staying put on an old version won't do anything at all.

I tested the patch (on 3.14.0) and work very well! 7 reboot times without force VGA and no blank screen. Thanks

Strange. What's your kernel config? CC Rafael.

You guys just don't solve the bug at that time.

Just to let you know: Version 3.14.1 doesn't work. Version 3.15-rc2 does.

For me it's all workaround, all over the place. This bug sometimes is hide for some code, and sometimes it's show up with some like the "cpuidle: Make it clear that governors cannot be modules". I don't think it's over, until someone figure out what the real cause of this bug. Or it will came back on the future, to haunt us again.
Comment 51 Bob Raitz 2014-04-24 06:54:19 UTC 
Since I've already got three instances of red, I'll just say that as long as the 3.15 stays unmolested in the video driver/drm/whatever_makes_it_work section, and I can move on kernel wise, and not have to deal with this again until I buy myself that new machine I want, then I don't much care if it was done with bubble gum and bailing wire. If things stay good in the 3.15, then the bug is fixed as far as I am concerned. I'll leave it up to the devs to do the required "i" dotting and "t" crossing.

Thanks for the refresh and pointers. I seem to have received 43k and sent 1k emails since then, I can't quite remember them all.

Reassing to Rafael, do you have any idea why

    cpuidle: Make it clear that governors cannot be modules

regresses?
Comment 54 Bob Raitz 2014-04-29 07:14:25 UTC 
Update: Version 3.14.2 doesn't work. Version 3.15-rc3 does.
Comment 55 Rafael J. Wysocki 2014-04-30 21:21:03 UTC 
OK, so it looks like we have a fix in 3.15-rc3, right?
Comment 56 Bob Raitz 2014-04-30 23:34:36 UTC 
More like the fix came along at 3.15-rc2. I have not checked whether 3.15-rc1 works, but it would be easy to find out.
Comment 57 Bob Raitz 2014-04-30 23:56:38 UTC 
That rather quick reboot into a working CLI tells me that the problem appears fixed with 3.15-rc1. I hope it will stay that way.
Comment 58 Bob Raitz 2014-05-07 08:10:36 UTC 
3.15-rc4=good. 3.14.3=bad.
Comment 59 Rafael J. Wysocki 2014-05-07 18:14:36 UTC 
OK, finger crossed.

I would like to know which commit fixed it, but marking as resolved.
Comment 60 Bob Raitz 2014-05-07 19:02:43 UTC 
I have no clue. Just don't undo what y'all did, and perhaps this machine might have a bit more life in it, noisy fan notwithstanding.
