Patch_SG0000615_Release_Note This release note describes patchSG0000615 to IRIX 5.3. This patch updates the file /var/arch/libvl/ev1.so. 1.1 Supported_Hardware_Platforms This patch contains Galileo/Indigo2/Indy Video bug fixes for Indigo (Elan, XZ, XZ), Indigo2 (EXtreme, XZ, XL), and Indy (XL). Supported processor types include the R4000, R4400, and the R4600SC. The software cannot be installed on other configurations. 1.2 Supported_Software_Platforms This patch contains bug fixes for IRIX 5.3 for the above hardware platforms. The software cannot be installed on other configurations. You will need to install dmedia_eoe 5.5 as the prerequisite for patchSG0000615. This patch is a superset of the previous 5.3 patchSG0000362. It is not necessary to install patchSG0000362 prior to installing this patch as this patch incorporates all of the fixes provided by patchSG0000362. 1.3 Special_Installation_Considerations Installing this patch updates a DSO used by the video daemon (videod). The inst exit operation will restart videod to force it to use the newly installed DSO. When videod is restarted, all currently running VL applications may terminate once their connection to videod is broken by this procedure. 1.4 Bugs_Fixed_by_Patch_SG0000615 This patch contains fixes for the following bug in IRIX 5.3. Bug numbers from Silicon Graphics bug tracking system are included for reference. o Inperson 2.0 snap video on Galileo doesn't work.(Bug #278648) There seems to be a race condition between InPerson checking for valid frames and the videod's transfer thread starting. Videod may return the BeginTransfer succeeded even before the transfer thread had a chance to run and start the ioctl. Also the Galileo DD layer fails to realize the path by not decrementing the user count when the path goes down to done using. Additionally, the following bugs are carried over from obsoleted Patch SG0000362. - 2 - o IndyVideo vcp won't let you switch inputs among input ports, (Bug #263788). Changing the video input selection is now possible while a video transfer is active. Since this patch now allows one to change the input selection, the users must be aware that changing inputs which result in either video standard or pixel timing change, (i. e. NTSC/PAL and CCIR/Square pixel), can produce/provide video which is not decoded/encoded correctly by Galileo or IndyVideo hardware. Galileo and IndyVideo video will not automatically reconfigure upon pixel timing or video standard change. These configurations must be explicitly set be the user when no video transfers are running. o ErrorF() symbol undefined in ev1.so (Bug 266241). This function was improperly referenced in the libvl portion of ev1.so. This reference has been removed. The error condition that resulted in the problem initially is that ev1.so, on behalf of the VL client, opens /dev/graphics in order to issue ioctls to determine to which head of a multi-head system the video board is attached. If the VL client was using OpenGL, then opening /dev/graphics (IrisGL) resulted in the graphics driver rejecting the second open (see /var/adm/SYSLOG). The current solution is if /dev/graphics (IrisGL) fails to open, then /dev/opengl (OpenGL) is opened. Depending on the mode already established by the VL client program, this may or may not result in a syslog message being written when vlCreatePath() is invoked. This message will be of the form "gfx: attempt to do both IrisGL and OpenGL rendering from the same process denied". For now, just ignore the syslog message. 1.5 Subsystems_Included_in_Patch_SG0000615 This patch release includes these subsystems: o patchSG0000615.galileo_sw.eoe 1.6 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 - 3 - 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 - 4 - where xxxxxxx is the patch number.
