Patch Name: PHSS_11405 Patch Description: s700 10.20 OpenGL 1.1 Revision 1.01 Runtime patch Creation Date: 97/06/24 Post Date: 97/07/30 Hardware Platforms - OS Releases: s700: 10.20 Products: OpenGLRunTime B.10.20 OpenGL 1.0 Runtime Environment Filesets: OpenGLRunTime.OPENGL-RUN OpenGLRunTime.OPENGL-SHLIBS Automatic Reboot?: Yes Status: General Superseded Critical: No Path Name: /hp-ux_patches/s700/10.X/PHSS_11405 Symptoms: PHSS_11405: - See defect description. Defect Description: PHSS_11405: - Fragments that lose the alpha test were nonetheless updating the depth and stencil buffers when using VMD/VGL or when texture mapping without TM hardware. - Fixes problem with lines of width < 0.5 not being rendered when using VMD/VGL or texture mapping with no TM hardware. - Fixes problems with writing stencil values in VMD/VGL or when texture mapping with no TM hardware. - Fixes glCopyPixels from incorrectly performing a copy when copying from one color buffer to the other. - Under some corner case timing situations when using indirect contexts with HP OpenGL Release 1.0, incorrect X or GLX error messages can be reported from the X Server. - If a memory allocation error occurs while processing glXUseXFont(), the PixelStore attribute values are not restored as they should be. - VMD/VGL and texture mapping w/o hw texture support could incorrectly clip filled primitives if glViewport mapped NDC to an area larger than the window size. This was causing incorrect rendering and core dumps. - For Release 1.0 of OpenGL, if an X Server is run in multi-screen mode with an HP_VISUALIZE_?X screen and a non HP_VISUALIZE_?X screen, the non HP_VISUALIZE-?X screen will not operate with HP OpenGL unless the HPOGL_FORCE_VGL environment is set in the client environment. - When using occlusion culling the test may indicate that the object was completely occluded when it actually wasn't. This is because we didn't wait for all the pixels to get written before looking at the HW status. - When running in indirect (protocol) mode, large OpenGL replies such as glReadPixels() may fail and generate improper Xlib errors. - Texture coordinates are not getting correctly reset to the default values of 0,0,0,1. - Autogen mipmap memory corruption fix. - If a customer closes one X Display connection that has been used for OpenGL, and then immediately opens and attempts to use another for OpenGL, their application may abort because an attempt is made to access global last context and drawable information that was freed during the close display operation and may have been re-used. - This will fix a small offset that when mipmap selection for filters NEAREST_MIPMAP_NEAREST and LINEAR_MIPMAP_NEAREST. - This will fix mipmap calculation coming very near horizontal or vertical lines. - This will fix texture mapping running over the edge when linear interpolated and using clamp to edge.

Back up your system before installing a patch. 2. Login as root. 3. Copy the patch to the /tmp directory. 4. Move to the /tmp directory and unshar the patch: cd /tmp sh PHSS_11405 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHSS_11405.depot 5b. For a homogeneous NFS Diskless cluster run swcluster on the server to install the patch on the server and the clients: swcluster -i -b This will invoke swcluster in the interactive mode and force all clients to be shut down. WARNING: All cluster clients must be shut down prior to the patch installation. Installing the patch while the clients are booted is unsupported and can lead to serious problems. The swcluster command will invoke an swinstall session in which you must specify: alternate root path - default is /export/shared_root/OS_700 source depot path - /tmp/PHSS_11405.depot To complete the installation, select the patch by choosing "Actions -> Match What Target Has" and then "Actions -> Install" from the Menubar. 5c. For a heterogeneous NFS Diskless cluster: - run swinstall on the server as in step 5a to install the patch on the cluster server. - run swcluster on the server as in step 5b to install the patch on the cluster clients. By default swinstall will archive the original software in /var/adm/sw/patch/PHSS_11405. If you do not wish to retain a copy of the original software, you can create an empty file named /var/adm/sw/patch/PATCH_NOSAVE. Warning: If this file exists when a patch is installed, the patch cannot be deinstalled. Please be careful when using this feature. It is recommended that you move the PHSS_11405.text file to /var/adm/sw/patch for future reference. To put this patch on a magnetic tape and install from the tape drive, use the command: dd if=/tmp/PHSS_11405.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: None
