[pardon the trashed message-id and the broken mailer I am using. Soon, I promise,
I will start using a real mail client.]
Yes. Knew that. I was referring to r300.sf.net:
"Current status
* DRM kernel module updated.
* 2d driver updated - CP acceleration appears to work correctly."
I have tried the two patches for linux-2.6.9-rc2 and xorg-x11-6.8.0. A few
notes:
kernel patch:
Added my pci id to drm_pciids.txt, and got:
[drm] Initialized radeon 1.11.0 20020828 on minor 0: ATI Technologies Inc
RV350 AR [Radeon 9600]
Not sure if I should add the secondary pci id. The README doesn't say.
BTW: 2.6.9-rc2 shows a duplicate pci id in drm_pciids.h :
{0x1002, 0x4242, PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0}, \
{0x1002, 0x4242, PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0}, \
# lspci
:01:00.0 VGA compatible controller: ATI Technologies Inc RV350 AR
[Radeon 9600]
:01:00.1 Display controller: ATI Technologies Inc RV350 AR [Radeon 9600]
(Secondary)
# lspci -n
:01:00.0 Class 0300: 1002:4152
:01:00.1 Class 0380: 1002:4172
But my card is an XT (rv360). I bought it as an XT. The print on the chip
says XT. And X agrees.
Xorg patch:
I added the patch on top of gentoo's 6.8.0-rc1. Gentoo do use a few patches
on top of vanilla Xorg...
(II) Primary Device is: PCI 01:00:0
(--) Assigning device section with no busID to primary device
(WW) RADEON: No matching Device section for instance (BusID PCI:1:0:1) found
(--) Chipset ATI Radeon 9600XT AR (AGP) found
If I load "dri" in my xorg.conf, the graphics gets wedged as soon
as I start X. I get more or less garbled stuff from the previous session. I
can move the cursor, but that's it. I can not exit from X with
ctrl-alt-backspace, or shift to the console with ctrl-alt-f1. I also tried
without radeonfb, just in case. I see no evidence of problems in the Xorg
log with dri, which I can review after rebooting via sysrq. Of course, if
the machine panicked, nothing got to the kernel log. And no, my wireless
keyboard does not have keyboard leds..
I am currently without a secondary machine, so i am unable to (try to) log
in via the network to check the kernel log. Will do later this week.
I have attached a diff between Xlog with and without dri, in case it is of
any use to anyone.

If you take something like the voodoo1 which essentially has two fixed modes, or vesafb its obviously a bit different (ditto a lot of embedded devices) You also want one mode embedded in every driver so that if the user space fails, aliens eat your network connection, it panics while mode switch computing or the like you can get a mode to see what went bang. Thats probably "single console 640x480 vga timings" for the general case and also does for boot up until userspace on disk (or initrd) has the video initialized the way the user wants it in the end. We also mooted caching settings when it made sense (eg when the computation is hard and the mmio whacking trivial) to get better mode change performance on vt flip.

Re: Improve state emitting for ipers
Eric Anholt wrote: Yeah, it was clear that we used to emit in whatever order, and that would have been nicer. At this point I'm seeing about 5% CPU time in EmitState for ipers, which seems pretty hefty for such a small bit of code, but I didn't see much obvious for improvement. That's indeed quite a bit. It's not enough though to really be concerned about it at the moment imho. Fixed order (at least within limits) being required certainly makes sense to me. I've found that docs sometimes say things like, "Writes to this register take no effect if bits X of register Y are not set to Z." It may be that those dependencies were just not recorded. It's just suspicious because there seems to be nothing at all about it in the documentation (well don't ask me, I don't have any...). I certainly think it's a good idea. However, I still think it should be possible to lock across multiple buffers, to make it possible to emit larger numbers of vertices at once (for instance for things like glDrawElements), which, as far as I understand, just cannot work if you're restricted to one buffer. Multiples of which buffers are you talking about here? Well, I'm not really sure about it. But it looked to me like there might be problems wrt context switching if your vertex data doesn't fit into one vertex buffer (basically you fill up one buffer, another app another one, and I'm not too sure offsets and such will be correct). Well maybe I'm wrong. Roland --- This SF.Net email is sponsored by: YOU BE THE JUDGE.

I am running viewperf-7.1.1, now.
Have viewperf-8.0.1, too.
Ian can you please check why we get empty/black windows with SMP on viewperf
for some tests (e.g. 'ugs').
You have to compile with '-DMP'.
# Add -DMP to the following line to build a multithreaded viewperf
DEFINES = -DXWINDOWS -DSEARCHPATH -DLINUX -DPNG -DMP
And modified 'EnvLINUX.c' version.
Add this:
/**
*
* GetNumProcessors - return number of processor on system
*
* Description:
* For MP execution, then number of processors is used for identification of
* of the number of graphics threads to exploit.
*
* Returns:

*
* Side Effects:

*
* Errors:
* no errors, if function fails the string 1 is returned
*
* Revision History:
*Initial Release
*
*/
int
GetNumProcessors()
{
return (2);
}

Second,
there is something wrong (maybe together with latest KDE 3.3.0 on my SuSE 9.0)
because in _all_ texture modes there is superimposed 'konsole' output in
every ~/results/*/*.png images.
See attached example (proe02.png).

Hi. I am very happy to see that the more recent Radeons are being looked into. A few questions: 1. Is the rv360 (9600xt) close enough to the developers hardware to a) benefit from the 2d improvements already made w.r.t. CP acceleration b) be of any use for testing purposes If the answer to a) is "don't know" I'll be happy to try. But I'll skip it if somebody says "don't bother". 2. Should I assume that you guys will stick to 6.7.0 until a more uptodate binary driver is available? 3. Anyone tried to patch 6.8.1 with the 2D patch? and finally: 4.

That has always made sense as the effects are often bizarre like probably not being able to use the vnc driver and trident driver together even though they share an author. I don't believe X should change on that issue. The question is one of additional programs that come with X - that is what the Linux DRI kernel module really is. Currently almost everyone in the X world is using some GPL software with their X server, it just happens to be in a different tarball/rpm/dpkg/... > I also expect that as the releases become more modular, this situation > also becomes more modular and less of an issue in any case.

The driver almost always needs to go to user space to get the file of mode line overrides that the user can create. But there is nothing stopping you from building everything in the kernel. I'd just rather not have 100K of resident code waiting around for something that doesn't occur very often. For the radeon sample I'm working on I have moved everything to user space except for a couple of small helper functions that directly play with the registers. Note that all mode setting in X occurs completely in user space so you can't argue that it can't be done. > > How are errors going to be communicated in this scheme?

I don't see why it can't either, besides that we've never formally stated that that's okay. If you're not going to link the GPL-licensed bits with a non-GPL kernel, then having GPL bits in the tree isn't a big deal. My strong preference is to minimize GPL code in the tree, for the usual contamination reasons. But either way, we need a formally stated policy. - ajax pgpVG6CNrXMr1.pgp Description: PGP signature
Re: DRM radeon i2c support and GPL
Alan, Please read, understand and comment on the license policy strawman I posted both to dri-devel and the xorg list. It is a strawman, a first draft, and as I understand my intent, is specifically intended to make it possible to permit such situations. Whether it actually says that clearly, is, of course possibly questionable ;-). Such policy can only be set by the community of course, and that requires discussion. I also expect that as the releases become more modular, this situation also becomes more modular and less of an issue in any case. I personally prefer that kernel stuff be integrated in the kernel, but that is because I always find having more than one version is usually error prone (the same reasons we're trying to get things like freetype, xterm, fontconfig/xft all from upstream modular sources, rather than the current integration of stale bits). - Jim > Subject: Re: DRM radeon i2c support and GPL > From: Alan Cox <[EMAIL PROTECTED]> > To: [EMAIL PROTECTED] > Cc: Jon Smirl <[EMAIL PROTECTED]>, > Discuss issues related to the xorg tree <[EMAIL PROTECTED]>, > DRI Devel <[EMAIL PROTECTED]> > Date: Tue, 21 Sep 2004 10:48:05 +0100 > > On Maw, 2004-09-21 at 08:58, Kean Johnston wrote: > > That's not a statement thats safe to make.

My understanding is that if/when BSDs (and others) implement an I2C system, it'll probably be compatible with the Linux one from the userspace side (i.e. the syscalls will have the same semantics) but certainly not from the kernel side: there's not point for them to be compatible with the Linux architecture as they can't import its drivers. I don't the DRM drivers, but if they use I2C from the kernel side there's not point in licensing that code for multiplatform. Xav --- This SF.Net email is sponsored by: YOU BE THE JUDGE.

Re: DRM radeon i2c support and GPL
I picked a very simple piece of code to start out with as a test case. The I2C code is only a hundred lines and could be rewritten. But what's the point, BSD doesn't have Linux's I2C driver system. This code has no value anywhere but on Linux. That's not a statement thats safe to make. BSD (or any other OS that XOrg supports) may not have Linux's I2C driver system. TODAY. What if, next week, BSD gets such a beast, or HP-UX does, or Solaris or whatever. Maybe now that code that is currently only of value on Linux is of value on a broad range of systems. Now you have the potential for a broad range of non-GPL systems to be dependent on GPL code, which is, after all, the point I think the original strawman paper was addressing. If XOrg is trying to be "license agnostic", it is going to need to stay away from the GPL. The current MIT style license seems to be quite acceptable to GPL-centric projects.
