feature disables the reserved area of memory that the kernel provides
for applications to place their mmap and shmat mappings. For more
information, see the mmap(2), shmat(2), syssgi(2), and
sgi_use_anyaddr(1) man pages.
• Support for weightless pthreads; they allow you to lower the priority
of a process by using the npri -w command. For more information,
see the npri(1) man page.
• Support for an increased maximum number of logical unit numbers
(LUNs) in the SCSI infrastructure from 64 to 255. This change impacts
only the fcadp and qlfc fibre channel drivers and they will now
enforce this LUN limit. If a LUN is greater than 255, it will be ignored
after issuing a message to this effect. If you use large numbers of
LUNs, you can exhaust the hardware graph. You may need to use the
systune command to increase the hwgraph_num_dev parameter to
let the kernel build larger hardware graphs.
• Support for licensing of partitioned environments. For more
information, see IRIX Admin: Software Installation and Licensing.
• Support for the PCI Hot Plug infrastructure on the SGI 3200, SGI
3400, and SGI 3800 servers.For more information, see the
pciconfig(1) man page for specific administrative options.
• Support for HP LaserJet 4050 and HP LaserJet 8100 printers
