nvidiafb: allow ignoring EDID info

From: Giuseppe Bilotta <[email protected]>

Some nVidia video cards have broken EDID information. Using nvidiafb with CONFIG_FB_NVIDIA_I2C enabled on these systems causes the console framebuffer to use wrong timing information, causing the display to be extremely 'snowy'. Since most distribution kernels are compiled with CONFIG_FB_NVIDIA_I2C enabled, this prevents usage of the nvidia framebuffer on said broken system without recompiling the kernel (or at least the nvidiafb module).

Solve the issue by introducing a new boolean module parameter (useedid) which can be set to 0 to prevent the driver from using the EDID information.

---

If this patch is accepted, we can probably get rid of CONFIG_FB_NVIDIA_I2C altogether.

I don't know whether this is possible, but wouldn't be a cleaner approach be to put this parameter to something fb specific and not nvidia specific? As Nvidia fb proabably isn't the only one using edid and so it wouldn't be necessary to introduce such a parameter for every fb driver...

That's a pretty sad solution. Is it possible to detect these bad cards at runtime via ther behaviour? If not, can we generate a blacklist for the known-bad cards based on PCI IDs or something?

Because most users won't even be aware of the module option: they'll just know that their card doesn't work right.

This isn't a card problem this is a monitor problem, the card just passes through the edid data from the monitor... or else the programming of the card registers from edid is wrong..

In which case the same problem would occur with different video cards, so this patch should be some generic thing, available to all drivers, no?

It should be in the fb layer not card specific.. as it may happen on any card...

Dave.

Although solving the problem at the fb layer level is probably the correct/best way to do it, I am not aware of people having problems with broken EDIDs and non-nVidia cards. By contrast, workarounds for nVidia and broken EDIDs is a very common thing to do even on Windows. Both the Windows and the Linux proprietary drivers need SoftEDID specifications to work around these problems. I don't know if this is just because of the way the driver are written, though, or if nVidia cards are particularly unable to handle monitors with broken EDIDs.

Plus, providing an fb-layer-level solution is way beyond my kernel programming experience :)

Not all drivers have support for reading EDID information, so in many cases it just "works". My old monitor had garbage in the EDID eeprom and I had to pass "ignore_edid" to radeonfb (before I reprogrammed the eeprom that is :P).

I'll try to code something in the weekend.

Do, or do not. There is no try.

I'm somewhat stuck. fbmon has the library functions to parse and optionally fix EDID block, but it lacks the knowledge of the source of the data; IOW it's not possible to ignore the EDID coming from a certain head, the flag would be global (which may be less that optimal with multi-head setups).
So instead of adding an option I'd use the existing broken EDID db, adding another state (say 'unfixable') which causes the data to be discarded. Comments?

Giuseppe, can you send me the EDID block of your monitor?

Luca

Sbagliare ? umano, ma per incasinare davvero le cose serve un computer.

I'd gladly do it, if I knew how to retrieve it ... because apparently, get-edid doesn't work, even though both the nv driver for X and nvidiafb manage to retrieve it.

This is the output from get-edid

get-edid uses the BIOS, while the other two talk directly over the I2C bus.

Try loading i2c-dev (I2C_CHARDEV); With i2cdump[1] you can read the EDID block, which resides at address 0x50:

i2cdump N 0x50 (where N is the bus number)

If you are unshure about bus number try with all the available /dev/i2c-* devices (you may want to unload HW monitor drivers first, so you don't poke at random stuff).

There is no such thing as /dev/i2c* UNLESS I load nvidiafb. When I load that, I get three busses (i2c-0, -1, and -2), but i2cdump N 0x50 gives me a nice tableau of X's all around, for all values of N. This is using kernel 2.6.18-3 stock Debian kernel. I'll keep trying with some variations, to see if I can get more sensible information.

Giuseppe "Oblomov" Bilotta

There is no stand alone nvidia card i2c driver. Its the issue of sharing device interfaces with the same hardware problem again!!! There is a patch for DRI and fbdev but it really looks like we need a generic solution.

Nah, nvidiafb registers the I2C busses, you can drive them with whatever you want through the devices exported by I2C core.
The fact the none of them work makes me think that the EDID is coming from the BIOS, we do VBE calls in real mode during early kernel setup.

Ditto!

It also seemed that my kernel compiling sk1llz had gone AWL, I couldn't get the newly compiled kernel to run, until I realized the initrd.img was mislinked. Anyway.

Your patch has an immediately visible effect of reducing snow: it seems that now that you fixed the access bug the EDID is properly /not/ used. dmesg | grep nvidiafb now claims the following:

"""

nvidiafb: Device ID: 10de0112
nvidiafb 0000:01:00.0: Unable to read EDID block.
nvidiafb 0000:01:00.0: Unable to read EDID block.
nvidiafb 0000:01:00.0: Unable to read EDID block.

(it actually gave the "I2C probe failed ..." message on console, but it's not appearing in the dmesg, obviously, since it's a simple printk)

nvidiafb 0000:01:00.0: Unable to read EDID block. nvidiafb 0000:01:00.0: Unable to read EDID block. nvidiafb 0000:01:00.0: Unable to read EDID block.

nvidiafb: Panel is TMDS
nvidiafb: MTRR set to ON
nvidiafb: Flat panel dithering disabled
nvidiafb: PCI nVidia NV11 framebuffer (32MB @ 0xE0000000)

"""

So the EDID still seems to be totally inaccessible (which means I can't really tell why/when/where it's b0rked).

Finally, as I mentioned, console still has a little snow. It's barely perceptible in common console usage because the monitor is mostly black, but can get annoying with fullscreen apps à la mc.

This extra snow *might* be the effect of bandwidth limits Antonino Daplas was referring to in this lkml message:
http://lkml.org/lkml/2005/10/1/7 but I'll have to enquire on this further.

The patch should be correct, but I fail to see how EDID reading succeded before.

Maybe the snow was caused by the driver hammering the I2C bus. Just guessing...

It it was so, it wouldn't appear when I disabled EDID parsing because it wouldn't touch the I2C bus at all. But it appears just the same.

What I meant is we can't load the i2c code seperate from the fbdev driver.

Of course :)

There may be a bug in the serial clock line control, at least the code looks strange. I'll check and come back with a patch ASAP.

If you can find post the manufacturer and model number we can place it on the backlist in fbmon. Also we should figure out what is wrong and fix it.

It's the UltraSharp UXGA display that used to come with Dell Inspiron 8200, 15" with a resolution of 1600x1200. I've been looking all around for more info on it, but the only things I could find were posts that remarked the problems Windows nVidia drivers have with some of these (no image when running at 1600x1200), and other posts about banded gradients with Windows drivers on Radeon video cards (but I get banded gradients also win my nVidia card, on Linux, regardless of which driver I use, binary, nv or nouveau).

As mentioned in another post in this thread, I can't get any info out of the i2c busses, because even when I have them available (i.e. after loading nvidiafb) I get XXXX all around (on all three of them). Suggestions on how to get the information welcome.

Giuseppe "Oblomov" Bilotta

Is this the same monitor you posted here?

http://marc.theaimsgroup.com/?l=linux-kernel&m=112807065616218&w=2

If yes, we already have the manufacturer and model code. The main problem is that the EDID of this display has no sync range (H: 75-75kHz and V: 60-60Hz). Extending Hsync from 30-75kHz as a fix to the EDID block shouldn't be too hard.

I already have a patch for this which I forgot to send to you before :-). If you can confirm that this is still the same hardware, I'll send you a test patch

Tony

Yes, that's it! Jeepers, I can't believe that even re-reading the past LKML posts (even those!) I couldn't find the EDID info and how we had gotten them. I guess I need stronger glasses.

Wonder why Luca's proposed patch makes the EDID undetectable, now, and why can't it be retrieved at a later time via i2c. Timeouts too small?

Yes, it's the same hardware. I can try the patch, with or without Luca's.

Giuseppe "Oblomov" Bilotta

Okay. Patch attached. You may want to #define DEBUG in drivers/video/fbmon.c so we can appreciate what happens. Load nvidiafb with DEBUG defined before and after applying the patch, then send your 'dmesg'.

Tony

fbdev: Add Ultrasharp UXGA to broken monitor database

From: <>

This particular monitor does not have a limits block and has only one set of monitor timings. Fix by adding a limits block to the EDID and extend the horizontal sync frequency range to 30 kHz and 75 Khz.

We're getting closer! The patch now works, and the dmesg has the following info:

However, I'm still getting the same snowy effects, which doesn't come as a surprise since the actual mode timings used are just the same ...

Giuseppe "Oblomov" Bilotta

Okay.

Yes, because the EDID has only 1 mode entry. But now you can use 'fbset 1024x768-60' (or any mode smaller than 1600x1200-60) for example and it should work. You might want to change vfmin and vfmax to 59 and 61 respectively just to get leeway for mode calculation errors. This is in drivers/video/fbmon.c, particularly b[5] and b[6] in this code:

	case FBMON_FIX_TIMINGS:
		printk("fbmon: trying to fix monitor timings\n");
		b = edid + DETAILED_TIMING_DESCRIPTIONS_START;
		for (i = 0; i < 4; i++) {
			if (!(edid_is_serial_block(b) ||
			      edid_is_ascii_block(b) ||
			      edid_is_monitor_block(b) ||
			      edid_is_timing_block(b))) {
				b[0] = 0x00; 
				b[1] = 0x00;  
				b[2] = 0x00;
				b[3] = 0xfd;   
				b[4] = 0x00;
				b[5] = 60;   /* vfmin */
				b[6] = 60;   /* vfmax */
				b[7] = 30;   /* hfmin */
				b[8] = 75;   /* hfmax */
				b[9] = 17;   /* pixclock - 170 MHz*/
				b[10] = 0;   /* GTF */
				break;
			}

			b += DETAILED_TIMING_DESCRIPTION_SIZE; 
		}

Also try doing fbset 640x480-60, 800x600-60, 1024x768-60 and 1280x1024-60, and if they displayed correctly, we can add these modes to your EDID block.

No, it doesn't. I've tried all the methods from 640x480 to 1600x1200, and they /all/ come up snowy. This is starting to look queerer and queerer. I've also tried changing vf min and max as you suggested:

and even the M and MR methods which you suggested in the other email. Since nvidiafb is being loaded from the command line because it's a blacklisted module otherwise, I've been using the mode_option option. However, neither the mode_option nor fbset seem to give me anything not snowy.

Damn.

Giuseppe "Oblomov" Bilotta

Before we proceed, do you agree that the patch will allow you to change video modes without disabling DDC support? So this is still a valid fix?

When does your display become snowy? Is the snow constant or does it only snow when doing heavy text operations, such as scrolling?

I presume that X's nv driver or vesafb does not exhibit this problem?

Tony

You're right, I hadn't realized that. I can now access all the sizes from 640 to 1600, so I would say the fix is valid.

The snowy is constant and abundant, and it seems to be independent of video size (640 through 1600) and screen occupation (single prompt line to fullscreen mc session) and usage.

X's nv gives a very clean display, /unless/ I load nvidiafb before: if I modprobe nvidiafb (it's a module, and it's blacklisted precisely for this reason), then the screen is very snowy with X's nv too.

Okay, thanks.

Hmm..., I really don't know how to fix this except to look at Xorg's code and look for a difference.

Tony

Keep in mind that setting nvidiafb to totally ignore the EDID (either by not compiling in EDID support or by using e.g. the ignoreedid patch I had proposed) the snow effect is extremely reduced, to the point of being barely perceptible during normal usage (not as clean as X, but still very good).

Also, I'm wondering if it might be worth looking at the progress done in nouveau, and the drm stuff they've implemented (or at least the new memory management and maybe some of the 2D stuff).

Giuseppe "Oblomov" Bilotta

I did not know that, just scanned the entire thread. Try this patch, it makes use of fb_ddc_read*() which I believe has extra steps to prevent display corruption. It also incorporates Luca's i2c fix.

Tony

nvidiafb: Bring back generic ddc reading

Make nvidiafb use fb_ddc_read(). This patch was submitted before but was reverted due to problems in a non-x86 platform. This includes a fix for that where ddc reading is bypassed if there is no DDC bus (duh).

Applied. No noticeable difference, in the sense that the EDID debug output is still the same and so is the snow effect.

Here's a temporary workaround:

In drivers/video/nvidia/nv_i2c.c:nvidia_probe_i2c_connector(),comment this out:

	if (par->chan[conn - 1].par)
		edid = fb_ddc_read(&par->chan[conn - 1].adapter);

and make sure CONFIG_FIRMWARE_EDID=y.

With this patch, I don't get any dmesg info about my monitor EDID, but I still get the snow. Could it be that there's something else on my system which is setting the video to some absurd timings when I switchg on the framebuffer console? I'm running an up-to-date debian unstable.

At this point, I don't know. You're the first person to report this kind of problem. I'm still studying the nvidiafb and Xorg source code.

Tony

BTW, you can also use CVT modes for nvidiafb, even if the mode in question is not present in the EDID block. For example:

video=nvidiafb:1024x768M@60 or 1600x1200M@60

(The 'M' tells fb_find_mode to do a CVT calculation instead).

If you use a reduced-blanking CVT mode, it might even reduce the snow of your DVI even at the highest resolution. So:

video=nvidiafb:1600x1200MR@60

(The additional 'R' will do reduced-blanking CVT calculation)

Yes, the patch does look correct. I also don't understand why Giuseppe's hardware failed to do i2c with this...
