Radeon Resuming from S3: Try 2

Radeon Resuming from S3: Try 2

[Andrew Barr]

Given the recent positive developments and success stories concerning resuming 
ATI hardware from S3 suspend, I thought I'd give suspending my desktop PC to 
S3. Briefly, relevant parts of my hardware:

- ATI Radeon 7000
- Intel AGP chipset
- Linux kernel 2.6.9, ACPI 20041105

I want to be able to use framebuffer (vesafb, for bootsplash). DRI is 
certainly not required. It appears I have two options: the s3_late_bios patch 
or dummydriver/resume-finish-split. What do I need to do to try each one? For 
example, I know I need to pass acpi_sleep=s3_late_bios to my kernel to use 
that patch. It's unclear to me what I need to do with the dummydriver or 
resume-finish-split patches. Can someone tell me what I need to do? I don't 
really need step-by-step instructions, just need to know what to do.

correct

Nothing. They don't need any kernel options to work. The dummydriver
only works
for two specific devices identified by their PCI-ID (or whatever you
call that).
It will *not* work for other devices.

You'll have better luck using resume-finish-split as I didn't see
anything device specific in there (well, I didn't look very long heh).

These two patches don't help resuming your Radeon, they just prevent a
freeze during resume caused by *other* devices.

My machine does freeze after resuming from S3. Is this caused by other devices 
(like the sound card, uses ALSA driver snd-cmipci)? If I _just_ have the 
Radeon problem, the machine should work fine except for the monitor being 
dead, right? In other words, I should be able to SSH in (which I can't)? I 
was under the impression that both the video not coming back and the freeze 
were caused by the Radeon, because before I bought the Radeon I was using the 
on-board graphics controller (Intel 82865G) and there were no problems.
