Refactor server-side __glXImageSize / __glXImage3DSize
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
I'm trying to get the patches attached to bug #2996 update. As part of
that, I'm generating some smaller, more trivial patchs to commit to the
tree /before/ RC1. I committed one really trivial one last night (the
EvalComputeK stuff). This one is a little bit bigger, so I'd appreciate
some review before I commit it.
Basically, this refactors __glXImageSize and __glXImage3DSize into a
single function. It replaces all calls to the old functions with calls
to __glXImageSize with the new parameter list.
I have also added 'target' as a parameter. This is a stepping stone to
the code in patch #2410. Basically, if the texture target is one of
GL_PROXY_*, the image size is always zero. This gathers all the checks
for that into a single place. I have *not* modified the existing
callers to take this into account. They still do their own checks for
GL_PROXY_*. However, when the generated versions of those functions are
added to the tree, they *will* rely on that.
The code growth is mainly due to the new 40 line comment before
__glXImageSize.
I have tested this with a few of the texture using demos and tests from
Mesa, including tunnel and texdown.

Please do not reply to this email: if you want to comment on the bug, go to the URL shown below and enter yourcomments there. https://bugs.freedesktop.org/show_bug.cgi?id=2766 --- Additional Comments From [EMAIL PROTECTED] 2005-09-28 15:54 --- (In reply to comment #1) I've turned the fallback off, since it seems GL_SPHERE_MAP should work, and apparently works in some cases. I've confirmed that R200_LOCAL_VIEWER did fix texcyl (just drop it into the TCL_LIGHT_MODEL_CTL_0 of r200_state_init.c to see), though reading gl specs and ati specs, I can't come up with a reason why. I think this is a common hardware limitation, Direct3d has a caps bit for exactly that (D3DVTXPCAPS_NO_TEXGEN_NONLOCALVIEWER, though it needs to be said the radeons do not set it). I believe the reason is that some calculations related to eye-coordinate transforms are shared between lighting and texgen. However, I'm wondering is it possible (and if not, what sort of lights will break?) to always set R200_LOCAL_VIEWER if texgen is enabled? It seems it's necessary to set _mesa_allow_light_in_model to 0 (same as fog already does) in that case, with that set lighting still seems to be correct if R200_LOCAL_VIEWER is always enabled, but the math behind it escapes me a bit. I think it would be needed for all texgen modes, not just GL_SPHERE_MAP, with probably the exception of the GL_OBJECT_LINEAR mode, on both r100 and r200. I'll code that up if someone else thinks this might be the correct thing to do :-). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. --- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl -- ___ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel

the code in patch #2410. Basically, if the texture target is one of
GL_PROXY_*, the image size is always zero. This gathers all the checks
for that into a single place. I have *not* modified the existing
callers to take this into account. They still do their own checks for
GL_PROXY_*. However, when the generated versions of those functions are
added to the tree, they *will* rely on that.
The code growth is mainly due to the new 40 line comment before
__glXImageSize.
I have tested this with a few of the texture using demos and tests from
Mesa, including tunnel and texdown.
It's been a long time since I've looked at this stuff, but I'm not
sure that __glXImageSize() is correct. Specifically, the last part of
the function:
[...]
if (imageHeight 0) {
imageSize = (imageHeight + skipRows) * rowSize;
} else {
imageSize = (h + skipRows) * rowSize;
}
return ((d + skipImages) * imageSize);
}
}
Why do skipRows and skipImages factor into the image size? I believe
the dimensions of the image going over the wire is W * H * D. The
skipRows and skipImages (and skipPixels) values just describe where to
find the W*H*D image inside of a larger image.
See figure 3.8 on page 131 of the OpenGL 2.0 specification for a diagram.
Consider a scenario in which you're replacing a single texel in a 3D
texture map. You've got a W*H*D 3D texture that in malloc'd memory
which you previously uploaded with glTexImage3D. To upload a single
changed texel in that volume at (x,y,z) you'd set
GL_UNPACK_SKIP_PIXELS=x, GL_UNPACK_SKIP_ROWS=y, and
GL_UNPACK_SKIP_IMAGES=z then call glTexSubImage3D(target, level, x, y,
z, 1, 1, 1, type, volume).
Over the wire, we should send a single texel so the result of
__glXImageSize should be pretty small. The __glFillImage() command on
the client side doesn't seem to use SKIP_ROWS or SKIP_IMAGES in the
way that __glXImageSize does.
Ian, you should test this with the drawpix demo: decrease the image
height to about half by pressing 'h'. Then increase the skipRows
value by pressing 'R'. Things should blow up on the server side if
the __glXImageSize computation is wrong.

xscreensaver freezes, reboot required
I do appologize if I'm cross posting here. I'm not sure which forum would be best to address this. I have a encountered an error when running xscreensaver-demo as a normal user. In Slackware 10.2 the daemon is not running by default and there is a popup window that promts to turn it on. If I click 'okay' then the screen freezes and I must reboot. I can't SysRq and I don't have another box to try logging into it and shutting it down. If I select 'cancel' then and then start the daemon from the menu everthing seems to work fine. No lockups. I encounter a similar issue with a dialog box in the game S.C.O.U.R.G.E: Heroes of a lesser renoun. Upon starting the actual game (once characters are created) I am presented with dialog box. The game runs behind this box and I can move the box around the screen, but as soon as I close this box then the game continues running for maybe 1-2 seconds before the system locks up again. Time to reboot. I've tried to debug the game with gdb but I get no output before the screen freezes. I've tried running different versions of the game both compilied by me and binary packages. I get the same results on Fedora Core 3 with kernel 2.6.9 as I do with Slackware 10.2 with kernel 2.4.31. I've tried xorg 6.8.1 and 6.8.2 and get the same results. The game does NOT crash with indirect rendering. It's unplayably slow but it can exit gracefully. A few bit that might help: r200 with TCL (it crashes even when I disable it) Radeon 9200 128M AGP I'll send my log if you need it, but other apps don't seem to suffer from this same issue when dri is enabled. P.S. By the way is it normal to see visual corruption in glxgears when page flipping is turned on? Again I'll post some screenshots if it will help. -Jason --- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl -- ___ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
