|---|---|---|
| bryce | heya | 01:41 |
| pcjc2 | I've got a confirmed hit on the 855 crash | 01:41 |
| bryce | excellent | 01:41 |
| pcjc2 | it crashes writing the PIPEACONF register in the restore path | 01:42 |
| pcjc2 | (At least that's where it crashed for Claudio Ritzert, who I tested the .deb I made with lots of debug output) | 01:43 |
| pcjc2 | I guess we might be seeing more of the same type of bug.. I'll see If I can put together an alternative restore sequence which avoids the crash, and hopefully get input from Intel as to the "rules" for this operation | 01:44 |
| === bryce nods | ||
| pcjc2 | The trick to get a decent log was to add sync(); after every log | 01:45 |
| bryce | is this the 133118 bug? | 01:45 |
| pcjc2 | and get the reproduction done with write-caching on teh HDD disabled | 01:45 |
| bryce | ahh that's a good note | 01:45 |
| pcjc2 | I was thinking of the clingers on to 127101 who claim its not fixed for them yet | 01:46 |
| bryce | ah gotcha | 01:46 |
| pcjc2 | its probably 108056 | 01:46 |
| pcjc2 | can't hurt to get the people seeing 133188 to test once we can fix the crash... it doesn't seem to make it crash every time, but might have other side-effects they are seeing | 01:48 |
| === bryce nods | ||
| pcjc2 | I expect the sooner this is fixed the better... there has to be a lot of Intel hardware out there which will make a Gutsy upgrade a bad experience | 01:49 |
| bryce | yup | 01:49 |
| bryce | I gather from 133188 that 855 is pretty widely used on server boards, so it sounds like a potential inhibitor for gutsy on servers | 01:50 |
| pcjc2 | I'm guessing its a similar pipe not enabled issue | 01:55 |
| pcjc2 | all other points where PIPEACONF is programmed, the DPLL is on | 01:55 |
| pcjc2 | we just restored the DPLL (possibly to an off state) | 01:55 |
| pcjc2 | Unfortunately, the routines which can turn the PLL on appropriately are liable to touch many other registers, so not great for the restore path | 01:56 |
| pcjc2 | heh.. comment in the code | 02:01 |
| pcjc2 | i830_display.c, line 965 | 02:01 |
| pcjc2 | "On 855, it can lock up the chip (and the entire machine)" (relates to them touching 3 registers, including PIPEACONF) | 02:02 |
| === bryce smells gun smoke | ||
| pcjc2 | Am now trying to read the code and find what conditions it _is_ programmed in. Might be a little detective / guess work. | 02:05 |

| pcjc2 | http://www2.eng.cam.ac.uk/~pcjc2/ubuntu/debug/xserver-xorg-video-intel_2.1.1-0ubuntu9~pcjc2.tst2_i386.deb | 04:34 |
| pcjc2 | Sources etc.. in the dir | 04:35 |
| pcjc2 | Its still got lots of sync() 'd debug output, but I've asked Claudio to see if it resolves the problem. | 04:35 |
| pcjc2 | I copped out in the end trying to fire up the DPLL to restore this register.. and took a similar route as the Palette. Don't restore it if the DPLL for that PIPE is off | 04:36 |
| pcjc2 | (For the palette we test the PIPEACONF register for being enabled, but its that register we're having trouble writing here.. its probably locking the HW state machine on write with no clock to synchronise to). | 04:36 |
| pcjc2 | We might even have got away with writing the palettes with just the DPLL enabled, but I guess we fixed that one already ;) | 04:37 |
