[IA64] Move include/asm-ia64 to arch/ia64/include/asm

2008-08-01T17:21:21+00:00

After moving the the include files there were a few clean-ups: 1) Some files used #include , changed to 2) Some comments alerted maintainers to look at various header files to make matching updates if certain code were to be changed. Updated these comments to use the new include paths. 3) Some header files mentioned their own names in initial comments. Just deleted these self references. Signed-off-by: Tony Luck

[IA64] Kernel parameter for max number of concurrent global TLB purges

2008-04-04T18:06:38+00:00

The patch defines kernel parameter "nptcg=". The parameter overrides max number of concurrent global TLB purges which is reported from either PAL_VM_SUMMARY or SAL PALO. Signed-off-by: Fenghua Yu Signed-off-by: Tony Luck

[IA64] Multiple outstanding ptc.g instruction support

2008-04-04T18:05:59+00:00

According to SDM2.2, Itanium supports multiple outstanding ptc.g instructions. But current kernel function ia64_global_tlb_purge() uses a spinlock to serialize ptc.g instructions issued by multiple processors. This serialization might have scalability issue on a big SMP machine where many processors could purge TLB in parallel. The patch fixes this problem by issuing multiple ptc.g instructions in ia64_global_tlb_purge(). It also adds support for the "PALO" table to get a platform view of the max number of outstanding ptc.g instructions (which may be different from the processor view found from PAL_VM_SUMMARY). PALO specification can be found at: http://www.dig64.org/home/DIG64_PALO_R1_0.pdf spinaphore implementation by Matthew Wilcox. Signed-off-by: Fenghua Yu Signed-off-by: Tony Luck

[IA64] workaround tiger ia64_sal_get_physical_id_info hang

2008-03-04T22:26:50+00:00

This fixes regression introduced in 113134fcbca83619be4c68d0ca66db6093777b5d Intel Tiger platforms hang when calling SAL_GET_PHYSICAL_ID_INFO instead of properly returning -1 for unimplemented, so add a version check. SGI Altix platforms have an incorrect SAL version hard-coded into their prom -- they encode 2.9, but actually implement 3.2 -- so fix it up and allow ia64_sal_get_physical_id_info to keep working.

[IA64] Export three symbols for module use

2008-02-04T23:46:23+00:00

Since kvm/module needs to use some unexported functions in kernel, so export them with this patch. Signed-off-by: Zhang Xiantao Signed-off-by: Tony Luck

[IA64] abstract SAL_CALL wrapper to allow other firmware entry points

2007-10-12T22:11:22+00:00

SAL_CALL() always calls through the ia64_sal function pointer. I am adding new functionality that needs the same conventions as SAL_CALL (FP regs saved/restored, sal_lock acquired, etc), but doesn't use the ia64_sal function pointer. This patch pulls the body of SAL_CALL out into a new "IA64_FW_CALL" that takes care of these calling conventions, but allows the caller to specify either ia64_sal or some other firmware entry point.

[IA64] move SAL_CACHE_FLUSH check later in boot

2006-10-31T22:32:10+00:00

The check to see if the firmware drops interrupts during a SAL_CACHE_FLUSH is done to early in the boot. SAL_CACHE_FLUSH expects to be able to make PAL calls in virtual mode, on some cell based machines a fault occurs causing a MCA. This patch moves the check after mmu_context_init so the TLB and VHPT are properly setup. Signed-off-by Troy Heber Signed-off-by: Tony Luck

[IA64] avoid broken SAL_CACHE_FLUSH implementations

2006-02-02T21:25:54+00:00

If SAL_CACHE_FLUSH drops interrupts, complain about it and fall back to using PAL_CACHE_FLUSH instead. This is to work around a defect in HP rx5670 firmware: when an interrupt occurs during SAL_CACHE_FLUSH, SAL drops the interrupt but leaves it marked "in-service", which leaves the interrupt (and others of equal or lower priority) masked.

[IA64] Split 16-bit severity field in sal_log_record_header

2005-12-13T18:41:49+00:00

ERR_SEVERITY item is defined as a 8 bits item in SAL documentation ($B.2.1 rev december 2003), but as an u16 in sal.h. This has the side effect that current code in mca.c may not call ia64_sal_clear_state_info() upon receiving corrected platform errors if there are bits set in the validation byte.
