+ Linux kernel release 2.3.xx for the IA-64 Platform
+ These are the release notes for Linux version 2.3 for IA-64
+ platform. This document provides information specific to IA-64
+ ONLY, to get additional information about the Linux kernel also
+ read the original Linux README provided with the kernel.
+INSTALLING the kernel:
+ - IA-64 kernel installation is the same as the other platforms, see
+ original README for details.
+ Compiling and running this kernel requires an IA-64 compliant GCC
+ compiler. And various software packages also compiled with an
+ IA-64 compliant GCC compiler.
+CONFIGURING the kernel:
+ Configuration is the same, see original README for details.
+COMPILING the kernel:
+ - Compiling this kernel doesn't differ from other platform so read
+ the original README for details BUT make sure you have an IA-64
+ compliant GCC compiler.
+ - Security related issues:
+ o mmap needs to check whether mapping would overlap with the
+ address-space hole in a region or whether the mapping would be
+ across regions. In both cases, mmap should fail.
+ o ptrace is a huge security hole right now as it does not reject
+ writing to security sensitive bits (such as the PSR!).
+ - General issues:
+ o Kernel modules aren't supported yet.
+ o For non-RT signals, siginfo isn't passed through from the kernel
+ to the point where the signal is actually delivered. Also, we
+ should make sure the siginfo data is compliant with the UNIX
+ o Hardly any performance tuning has been done. Obvious targets
+ include the library routines (memcpy, IP checksum, etc.). Less
+ obvious targets include making sure we don't flush the TLB
+ needlessly, etc. Also, the TLB handlers should probably try to
+ do a speculative load from the virtually mapped linear page
+ table and only if that fails fall back on walking the page table
+ o Discontigous large memory support; memory above 4GB will be
+ discontigous since the 4GB-64MB is reserved for firmware and I/O
+ o Correct mapping for PAL runtime code; PAL code needs to be
+ mapped by a TR.
+ o Make current IRQ/IOSAPIC handling closer to IA32 such as,
+ disable/enable interrupts, use of INPROGRESS flag etc.
+ o clone system call implementation; needs to setup proper backing
+ o SMP locks cleanup/optimization
+ o IA32 support. Currently experimental. It mostly works but
+ there are problems with some dynamically loaded programs.
