Dmesg before hot-plugging external monitor.

Netconsole output generated when the external monitor is hot-plugged.
I wonder if the patch from #28739 helps at all? It may be we're running into a DP programming conflict with the panel locking out any changes... Yes, this patch: make sure panel power is enabled on eDP (1.17 KB, patch) 2010-07-14 12:21 PDT, Jesse Barnes from #28739 helps quite a bit, but not entirely. Now with exactly the same set-up as before, but with the above patch applied, I see the following behavior: 1. I boot in runlevel 3, no X, with drm.debug=0xff 2. Captured the register dump (labeled regdump.nox.1) 3. I hotplug a VGA monitor, both the DP and VGA monitor show the same image. 4. Captured the register dump (labeled regdump.nox.2) 5. I unplug the VGA monitor, seems fine 6. The register dump at this point does not differ from regdump.nox.2 7. I captured the dmesg in dmesg.nox. 8. Laptop seems to be fine. However starting X will crash the computer. Second scenario (with X): 1. I boot in runlevel 5, with X, with drm.debug=0x06 (0xff will be too much data) 2. Captured the register dump (labeled regump.withx.1), and dmesg (dmesg.withx.1) 3. I hotplug a VGA monitor, the desktop extends to encompass both screens 4. Captured the register dump (labeled regdump.withx.2) and dmesg (dmesg.withx.2) 5. I unplug the VGA monitor. 6. The X screen goes black on the laptop. The mouse is still moving around, but some artifacts are shown) 7. I login via the network, captured a register dump (regdump.withx.3) and dmesg (dmesg.withx.3) 8. Laptop is wedged. Stopping X hangs it. Thanks again for your quick response! Phil. Created attachment 37088 [details]

Sounds potentially related to https://patchwork.kernel.org/patch/112571/ have you tried that patch? (In reply to comment #15) > Sounds potentially related to https://patchwork.kernel.org/patch/112571/ have > you tried that patch? Well, if it's not in 2.6.35-rc5, I haven't tried it yet. And patchwork.k.o seems to be down at the moment. Do you have an alternate location for the patch?

(In reply to comment #18) > Have you had a chance to try that patch yet? I just found the time. I have tried vanilla 2.6.35rc6 with the two following patches: make sure panel power is enabled on eDP (1.17 KB, patch) 2010-07-14 12:21 PDT, Jesse Barnes (same as before) and this new patch: Bug 28811 - [page-flipping] GPU hang when modeset after unplugging another monitor (under compiz) https://bugs.freedesktop.org/show_bug.cgi?id=28811 I still see the same behavior. One new thing to report: the bad behavior only happens when plugging then unplugging a VGA monitor. I have managed to get a DP to DVI cable, and with that one, when when using the DP connector, the hot-plug and hot-unplug work fine. Phil.

I have tested with same set-up as before plus the new patch from Dave (disable DAC on Ironlake also when doing CRT load detection), and it does not make any difference (still display corruption and crash upon hot unplugging the VGA connector).

All of Jesse's eDP fixes are available in git://git.kernel.org/pub/scm/linux/kernel/git/ickle/drm-intel.git drm-intel-next whereas this patch is available on the testing branch: drm-intel-staging.

Does this patch fix the > issue for you? It works for me... Yes! Finally! This patch fixes all the remaining hotplug / unplug issues for me. Plugging in a VGA cable works, unplugging it works, same for a DP cable. Thanks! Excellent, patch is on its way to Linus now. |
