pcjc2ah - see if the register access is too fast for the HW?03:43
pcjc2the other point in the code where the pallette is programmed made the assertion (in comments) that the PLL / clock had to be running03:44
pcjc2I'm presuming this is the case after we're restored the clock register (s) above03:44
brycemm could be03:44
pcjc2although I (vaguely) recall delays being used to wait whilst the PLLs stablise03:44
brycehrm, running this under gdb isn't working very well03:53
brycebbiab (dinner)03:53
pcjc2how comes?03:54
pcjc2not crashing with GDB?03:54
pcjc2or just not easy to trace through03:55
pcjc2It just occured to me.. the set_cursor_colors function sets the palette regs03:58
pcjc2and that is another place I've seen it crash (not that function specifically, but after reloading cursors)... I could never make it do it once I'd added a print statement to see what functions were being called... timing does look like a distinct possibility03:59
brycewhen running under gdb when I switch to tty1 it doesn't switch; the background turns purple though, and the system behaves erratically after that, until reboot04:10
pcjc2gdb presumably affects timing04:10
pcjc2I have absolutely no idea why... but that ramdac thing "seems" to make a difference here04:11
pcjc2when I patched it the other way (forced ramdac to load with SWCursor), it said it was already built in04:11
pcjc2you're supposed to need ramdac to do HW Cursors (and they program the palette)04:11
pcjc2but I don't see the intel driver using it04:12
bryce<bryce> mjg59: adding the usleep() had no effect; still crashed with gray block lockup04:14
bryce<mjg59> bryce: Ok, so probably not a timing issue. If you skip that block entirely, does it work?04:14
pcjc2for whatever reason, I'm not getting the crash05:01
pcjc2but it messes up the video overlay control registers05:01
pcjc2(and presumably has trampled a load of memory / IO somewhere)05:01
pcjc2before bug, I have XV frames flipping between buffers at 0x80004000 and 0x8010400005:02
pcjc2after, I've got 0x80000000 and 0x8010000005:03
pcjc2(sorry, those are the wrong way around)05:03
bryceafter running the -intel with the aforementioned loop blocks removed, I've been unable to reproduce the bug05:04
brycedeb, debdiff, etc. at http://people.ubuntu.com/~bryce/Testing/bug127101/05:04
pcjc2I'll test that here05:14
pcjc2See if I can get past running XV a 2nd time05:14
pcjc2sorry... something is still not right05:29
pcjc2just rebooting to make sure the video hardware is really clean05:29
pcjc2sorry... I've still got a crash here05:33
pcjc2am running compiz05:33
pcjc2(or whatever the fancy accelerated desktop is)05:33
pcjc2mplayer video.ogg05:33
pcjc2close mplayer05:33
brycelike I said on the bug, this fix is not intended to fix the Xv bug05:34
pcjc2switch to VT1 (nocrash with either your patch or my noramdac patch - goodness knows why), switch back05:34
pcjc2ok - is that a different known bug?05:34
brycethey both result in the gray blinking blocks05:35
pcjc2I've probably been seeing a slightly different crash05:35
brycebut one is 127101, the other is 14106305:35
bryceI don't know if yours is 141063, but it's not 12710105:35
pcjc2mine only occasionally resulted in blinking blocks - more usually a pallette corruption, followed by crash05:35
pcjc2did you try the ramdac thing?05:35
bryceit could be you're seeing multiple issues05:35
pcjc2I'm certain it must just be some fluke05:35
bryceno I stopped after my change seemed to resolve it05:36
pcjc2as it seemed to work.. but having chased the code paths which I commented out, shouldn't actually have any effect!05:36
pcjc2We need the Intel docs to resolve this _properly_05:36
bryceplus it's getting late and I'm going to be out the rest of the week at a customer site, so need to do some packing and spend a little time with the gf ;-)05:36
pcjc2Presumably there is a reason to restore the pallette regs05:36
pcjc2That sounds like a good point05:37
pcjc2its 4:37am here05:37
bryceyeah I was up late last night myself on this05:37
bryceyou'll probably have better ideas once you've had time to sleep on it05:37
pcjc2I've caught myself in a nasty insomniac cycle which will give me real problems for tomorrow's 9am lab demonstration!05:37
pcjc2I'll chase the report on the Xv bug, see what I can learn05:38

pcjc2Hi Bryce04:40
bryceheya pcjc204:40
pcjc2am playing with the Xv issue04:41
pcjc2I'm just trying to make sure it forces a reset of the Xv regs / setup after its mode-switched, see if that helps04:41
pcjc2I wonder if the mode-setting is clearing the Xv regs, and as we don't seem to be reprogramming them afterwards - it might be an issue04:42
pcjc2To be honest though, I don't know what bits of the driver Compiz invokes which would make it only appear with compiz04:42
pcjc2fixes the issue for me!04:43
bryceooh, awesome04:43
pcjc2Also, ubuntu patch 01 has a bug 04:43
pcjc2kindof... it introduces an extra condition test checking to see whether to return BadAlloc or not04:44
brycecan you report that to the ubuntu-x@ list?  I'm about to hop on a plane and will be gone the next couple days04:44
pcjc2but doesn't add () around it, the test is like (A && B || C)04:44
pcjc2where it should be (for clarity at least), (A && ( B || C))04:44
pcjc2I will disect to make sure it wasn't just this tiny little change (as well as my "hack" of a  forced reset) which helps04:45
=== bryce nods
pcjc2It shouldn't be the if statement, as if that were to be the problem, it would either return BadAlloc un-necessarily04:45
pcjc2or NOT return BadAlloc when it should.04:46
pcjc2We should probably send the info via Intel at least.. I'm so new to the driver - and they have the docs / knowledge of _how_ it should work04:46
pcjc2Being dumb... where is the ubuntu-x@ list subscription?04:47
pcjc2darn.... still managed hang the GPU mode-switching with Xrandr whilst its playing video04:50

pcjc2ok, can you point me at the upload?07:00

pcjc2I didn't think I had "G33" class hardware!07:04
pcjc2was it the kernel patch which was causing the corruption?07:07
pcjc2because the patch dropped from the xorg driver looks like a NOP on my hardware07:07
