[RFC] Intel OpRegion support for Intel post-965 graphics chips
ACPI OpRegion support for Intel Integrated Graphics is meant to improve
the communication mechanisms between graphcis driver and system/video BIOS.
The Intel graphics driver stack is composed of several different modules:
kernel drivers, user level drivers, the video BIOS, system BIOS,
and pre-programmed firmware tables. Communication between these various
components is complex and highly platform dependent in the past.
ACPI IGD OpRegion interface is intended to replace the various
inter-module communication schemes described above, particularly the
INT 10h and SMI mechanisms. With the new OpRegion interface,
system/video BIOS will send requests to kernel graphic driver for
configuring graphic hardware. With the graphic driver being the only
place to configure graphic hardware, many stability issues we encounter
in the current Linux graphics will be eliminated.
The patch is very simple now, we only enable the driver ready field in
the OpRegion memory. But it is needed by new platforms shipped with
intel-opregion-ready vbios. Otherwise hotkey may not work on these
platforms, since vbios will not do anything when driver is not ready.
ACPI video driver will not receive any VGA notifications from vbios.
We can do more things when the kernel modesetting branch is ready.
Thanks,
Hong

RE: DRI2 direct rendering
Kristian H?gsberg wrote on Tuesday, April 01, 2008 5:35 AM: Hi, I just committed the last big chunk of DRI2 work, the direct rendering support. With this, we can now do direct rendering to redirected windows and GLX_EXT_texture_from_pixmap even works, so compiz (and other Open GL compositing managers) can run in direct rendering mode too. I ended up rolling a couple of changes into the direct rendering work and the commits in mesa and xserver grew much bigger than what I would have liked. Short story is that the DRI2 interface and the legacy interface diverged and I had to break the DRI interface again. So I decided to make a couple of changes I'd been considering, most noticably, the GLX specifc, open coded __GLcontextModes struct is no longer part of the DRI driver interface, and with it glcore.h is also gone. This change is the cause of most of the code churn. I could have tried to split the commits up in a couple of independent commits, but it would be a lot of work and I figured it'd be nice to only have one commit that breaks the interface. The upshot is that git xserver AIGLX needs git mesa DRI driver and for DRI2, get the latest version of the xf86-video-intel intel-batchbuffer branch too. Is there an option to disable DRI2 (or say, switch to legacy DRI) for those who would stick to xf86-video-intel master branch (or 2.3) at this point?

[Bug 15203] r300 lockup
http://bugs.freedesktop.org/show_bug.cgi?id=15203 --- Comment #25 from Markus Amsler [EMAIL PROTECTED] 2008-04-01 12:27:49 PST --- I know now whats happening. If the ring buffer gets low on space radeon_wait_ring is called. If writeback is enabled radeon_wait_ring can run into the -EBUSY timeout, because it's possible that during the timeout the CP won't update the ring pointer (few slow gpu commands in the ring buffer). Now the -EBUSY timeout isn't handled at all, so the ring buffer gets overwritten, with undefined result. I'm still thinking of a clever way to fix this. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. - Check out the new SourceForge.net Marketplace.

http://bugs.freedesktop.org/show_bug.cgi?id=15203 --- Comment #26 from Roland Scheidegger [EMAIL PROTECTED] 2008-04-01 13:08:32 PST --- (In reply to comment #25) I know now whats happening. If the ring buffer gets low on space radeon_wait_ring is called. If writeback is enabled radeon_wait_ring can run into the -EBUSY timeout, because it's possible that during the timeout the CP won't update the ring pointer (few slow gpu commands in the ring buffer). Now the -EBUSY timeout isn't handled at all, so the ring buffer gets overwritten, with undefined result. I'm still thinking of a clever way to fix this. Ahhh timeouts... This is actually tricky. Now, just ignoring the error and overwriting the ring clearly is a no-no, maybe should just repeat until there's no error (of course, not quite indefinitely as the chip may have locked up). Or could just increase the timeout but that's ugly too. Note that you could get the same error case even if you update the ring ptr for every quadword read, since a single command can run for a very, very long time (certainly with indirect buffers). Or if you'd want to submit a large chunk at once and the ring ptr simply didn't advance enough until it hits the timeout. (That's about what I had in mind when I mentioned it might just hide a real bug...) -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. - Check out the new SourceForge.net Marketplace.

[Bug 15269] R200 crashes in glXMakeCurrent if GL_FRAGMENT_SHADER_ATI is enabled
http://bugs.freedesktop.org/show_bug.cgi?id=15269 --- Comment #1 from Roland Scheidegger [EMAIL PROTECTED] 2008-04-01 13:47:07 PST --- Hmm the driver can't handle an undefined shader, and we do state validation (why?) when a context is made current. Though I guess the same bug would happen if you'd just enable ATI_fragment_shader then try to render something without having the shader defined... -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. - Check out the new SourceForge.net Marketplace.
