RELEASE NOTES
1. Patch SG0000951 Release Note
This release note describes patch SG0000951 to IRIX 5.3.
1.1 Supported Hardware Platforms
This patch contains bug fixes for Indy and Indigo2 systems
with XL graphics. The software cannot be installed on other
configurations.
1.2 Supported Software Platforms
This patch contains bug fixes for Irix 5.3 IrisGL for Indy
XL and Indigo2 XL. The software cannot be installed on
other configurations.
1.3 Bugs Fixed by Patch SG0000951
This patch contains fixes for the following bugs in IRIX
5.3. Bug numbers from Silicon Graphics bug tracking system
are included for reference.
o Bug 311102 reports that Indigo2 Systems with XL
graphics and the new PM5 processor module (250Mhz, 2Mb
secondary cache, buffered PIO) were crashing due to a
FIFO error. Patch SG0000951 fixes this problem as well
as including bug fixes previously addressed in patch
SG0000773.
o The IrisGL library had referenced external symbol
"__rld_obj_head", defined in crt1.o, which is normally
linked in. Some programs built with non-standard tools
won't include crt1.o. This fix removes the reference to
the external symbol (Bug #289237)
o The IrisGL line clipping code could produce incorrect
results that can cause a segmentation fault when
accessing the zbuffer. (Bug 298039)
o The IrisGL calls to viewport (and
pushviewport/popviewport) were requiring a call to the
X server to determine window size and origin. This
'round-trip' call to the server was too slow, and a
change in this patch avoids the call altogether. (Bug
#253924)
o A bug in IrisGL acbuf operations could have caused a
kernel panic. (Bug #263250)
o Characters drawn with libfm routines were drawn smaller
on some models of monitors when in 1024x1280 display
mode. This was due to incorrect values returned by
getgdesc(GD_XMMAX) and getgdesc(GD_YMMAX) functions.
(Bug #236448)
o Drawing patterned lines in an ortho2D viewport could
make IrisGL software to go into an infinite loop. (Bug
#270882)
o Characters drawn with fogging enabled may not have
appeared correctly. (Bug #268215)
o Pixels drawn with a rectzoom factor of 2,2 may be drawn
without the leftmost pixels. This was also visible
with imgworks using a 200% magnification. (Bugs
#258686, #271078)
o The acbuf(AC_RETURN) operation would incorrectly blend
the returned data with the color buffer data if certain
blendfunctions were enabled. (Bug #256914)
o A bug with colorindexed shaded triangles and polygons
could yield incorrect color shading, especially with
large primitives. (Bug #272263).
o Current color value may not be restored correctly after
switching drawmodes to or from a 12 bit colorindex
buffers. Also, colorindex rectwrites seem to be
affected after such a drawmode switch, and the colors
may be drawn dithering between the pixel value and the
next higher pixel value. (Bug #268050)
o Errors in some lighting calculations have been fixed.
Incorrect normal transformations may occur with non-
orthonormal modelview matrices. (Bugs #238680,
#238705).
o Textured polygons using polygon patterns or using the
afunction were incorrectly rendered. (Bugs #267317,
#237905).
o When using the displacepolygon feature, polygons could
sometimes be drawn incorrectly. (Bug #270878).
o Certain artifacts could appear as a result of line
clipping when using the v2f call. Also, wide lines,
and circles drawn wide, could also show artifacts when
clipping. (Bug #284115).
1.4 Subsystems Included in Patch SG0000951
This patch release includes these subsystems:
o patchSG0000951.eoe1_sw.unix
o patchSG0000951.eoe1_sw.gfx_lib
1.5 Installation Instructions
Because you want to install only the patches for problems
you have encountered, patch software is not installed by
default. After reading the descriptions of the bugs fixed in
this patch (see Section 1.3), determine the patches that
meet your specific needs.
If, after reading Sections 1.1 and 1.2 of these release
notes, you are unsure whether your hardware and software
meet the requirements for installing a particular patch, run
inst.
Patch software is installed like any other Silicon Graphics
software product. Follow the instructions in your Software
Installation Administrator's Guide to bring up the miniroot
form of the software installation tools.
Follow these steps to select a patch for installation:
1. At the Inst>prompt, type
install patchSGxxxxxxx
where xxxxxxx is the patch number.
2. Select the desired patches for installation.
3. Initiate the installation sequence. Type
Inst> go
4. You may find that two patches have been marked as
incompatible. If this occurs, you must deselect one
of the patches.
Inst> keep patchSGxxxxxxx
where xxxxxxx is the patch number.
5. After completing the installation process, exit the
inst program by typing
Inst> quit
To remove a patch, use the versions remove command as you
would for any other software subsystem. The removal process
reinstates the original version of software unless you have
specifically removed the patch history from your system.
versions remove patchSGxxxxxxx
where xxxxxxx is the patch number.
To keep a patch but increase your disk space, use the
versions removehist command to remove the patch history.
versions removehist patchSGxxxxxxx
where xxxxxxx is the patch number.
INST SUBSYSTEM REQUIREMENTS No Requirements Information Available. INST SUBSYSTEM CHECKSUMS These checksums help to provide a 'signature' for the patch inst image which can be used to authenticate other inst images. You can obtain this kind of output by running sum -r on the image (from the command line): 45617 2 patchSG0000951 43297 3445 patchSG0000951.eoe1_sw 35476 2 patchSG0000951.idb INST SUBSYSTEM FILE LISTINGS The following lists the files which get installed from each subsystem in the patch:
