Remove CONFIG_FSYS option (it's the default now). Consolidate the various instruction patching routines into a single file (patch.c).

This avoids polluting ia64 code with definitions that are correct for ia32 only (for example, the ELF-related definitions would otherwise collide with ia64 ELF definitions).

This patch fixes some NULL pointer problems in perfmon. - fixes NULL pointer derefence in perfmon_mckinley.h when context is not loaded - fixes typo in pfm_write_pmcs()

Define ia64_max_iommu_merge_mask even without CONFIG_PCI, so that the simulator can link.

I found the attached patch necessary to allow compressed file systems to be used under the simulator. lib/Kconfig is needed to configure in the zlib routines.

Here is a patch to the ia64 Kconfig file that disables the EARLY_PRINTK menu option if a GENERIC kernel is selected. As we discussed last week, EARLY_PRINTK doesn't work for GENERIC kernels because readb/readl are machvecs.

ia64: NR_CPUS and number of CPUs While building a kernel for our 4-way Lion box, I made the mistake of setting NR_CPUS to 4. Little did I know that the Lion ACPI tables always list 8 CPUs (with only the first N enabled), and so the resulting kernel overflowed the smp_boot_data.cpu_phys_id array, crashed and burned.

fp assist. The problem lies with concurrent, potentially frequent updates of fpu_swa_count, which serves as the throttle for doing the printk(). A frenzy of concurrent updates will produce a frenzy of cacheline ping-ponging. The fix is simple: Only increment fpu_swa_count when the printk() is about to happen, which limits the increment to no more than four times every five seconds.

This patch contains a major rewrite of the perfmon subsystem to bring it to version 2.0. This version is NOT compatible with the existing perfmon-1.x version which was in 2.5 and still is in 2.4 kernels. This new codebase brings a lot of new features including the ability to attach to already running tasks, the ability the follow clone2, the ability to write your own sampling buffer format via kernel modules. It is also much more robust than its 1.x counter-part. This version supports the Itanium, McKinley and Madison PMUs. This is beta quality code and extensions to the interface are planned.

Make the size of the user stack based on the stack rlimit. The stack hard stack size now defaults to 2GB, but can be increased with ulimit up to 1/2 of the max mappable space in a region. For 16k pages, this makes the max stack size 8TB.

I was getting annoyed at having to mess around with the HP Simulator stuff when trying to compile generic kernels. Here's the fix that I came up with. It basically makes the HP Sim console another config option that depends on the HP sim serial code. It also sticks a couple of run-time checks in the init functions to only setup and run the code on hpsim machines.

This is a 2.5 version of the patch that I juggled around a couple of weeks ago. It's just a simple macro that allows one to check if the kernel is running on a specific ia64 platform.

The syscall optimization patches broke the OS INIT handler because SAVE_RESET was addressing relative to r12, which contains the virtual address of the stack pointer. Fixed by addressing relative to r2/r3 instead.

Please find the attached patch that: 1. Moves user stack flag memory access before srlz.i; 2. Moves mov b6=r22 as late as possible. 3. Changes (pSys) to (pLvSys) in skip_rbs_switch: section. IA32 syscall set pSys=1 but pLvSys=0. It's not necessary to clear bank1 r16-r19 registers for IA32 syscall. The number for leave_syscall is 268 cycles with this patch. The number is 295 cycles w/o this patch. It was 245 cycles with the original kee patched kernel. The 23 cycles come from restoring b6 operation which didn't exist in the orignal kee patch.

Only call get_scratch_regs() when pt is really needed. The extraneous calls to get_scratch_regs() can otherwise pick up the wrong address for pt. For example, calling unw_access_ar(&info, UNW_AR_BSPSTORE,...) before pt_regs had been reached could trigger this bug.

A bug-fix in IA-32 emulation ptrace code. The bug originally got introduced with the addition of FPXREGS support in ptrace. The bug is in ptrace get/set FPREGS routine. gdb by default will not use FPREGS routines when FPXREGS routines are supported. So we may not see this bug during normal gdb operations. But, if gdb (or any other app) directly tries to get/set FPREGS (probably an old version of gdb), it will end with an segmentation fault due to this bug. Attached patch fixes the issue. The patch is taken against 2.5.69. But it applies to 2.4 tree as well.

the first patch moves some definitions out of perfmon.c to perfmon.h (similar to what is in 2.4). The second patch contains a fix for the generic built. I did it that way to avoid other problems such as SIMSCSI depends on SCSI. so simply hardcoding this in the MAkefile could cause other problems. Anyway, SIMSCI is not defaulting to y when HP_SIM is defined so it is not so different.

I was building 2.5 and noticed that if you have raid5 configured as a module, then the arch/ia64/lib/xor.S would not get built (gets a make error since c file not there). Attached patch fixes that so xor.S gets built if raid5 is built-in or a module.

We need sometimes to load the physical address of a kernel object. Often we can convert the virtual address to physical at execution time, but sometimes (either for performance reasons or during error recovery) we cannot to this. Patch the marked bundles to load the physical address.

kernel patch. This patch makes it work again. The MCA path is similarly broken. Patch will follow later.
