ia64: remove now unused machvec indirections

2019-08-16T18:33:57Z

With the SGI SN2 machvec removal most of the indirections are unused now, so remove them. This includes the entire removal of the mmio read*/write* macros as the generic ones are identical to the asm-generic/io.h version.

ia64: remove support for the SGI SN2 platform

2019-08-16T18:33:57Z

The SGI SN2 (early Altix) is a very non-standard IA64 platform that was at the very high end of even IA64 hardware, and has been discontinued a long time ago. Remove it because there no upstream users left, and it has magic hooks all over the kernel.

[IA64] Update check_sal_cache_flush to use platform_send_ipi()

2008-06-11T23:40:33Z

check_sal_cache_flush is used to detect broken firmware that drops pending interrupts. The old implementation schedules a timer interrupt for itself in the future by getting the current value of the Interval Timer Counter + 1000 cycles, waits for the interrupt to be pended, calls SAL_CACHE_FLUSH, and finally checks to see if the interrupt is still pending. This implementation can cause problems for virtual machine code if the process of scheduling the timer interrupt takes more than 1000 cycles; the virtual machine can end up sleeping for several hundred years while waiting for the ITC to wrap around. The fix is to use platform_send_ipi. The processor will still send an interrupt to itself, using the IA64_IPI_DM_INT delivery mode, which causes the IPI to look like an external interrupt. The rest of the SAL_CACHE_FLUSH + checking to see if the interrupt is still pending remains unchanged. This fix has been boot tested successfully on: - intel tiger2 - hp rx6600 - hp rx5670 The rx5670 has known buggy firmware, where SAL_CACHE_FLUSH drops pending interrupts. A boot test on this machine showed this message on the console: SAL: SAL_CACHE_FLUSH drops interrupts; PAL_CACHE_FLUSH will be used instead Which proves that the self-inflicted IPI approach is viable. And as expected, the other tested platforms correctly did not display the warning. Signed-off-by: Alex Chiang Signed-off-by: Tony Luck

[IA64] allow user to force_pal_cache_flush

2008-05-14T22:42:07Z

The sequence executed in check_sal_cache_flush: - pend a timer interrupt - call SAL_CACHE_FLUSH - see if interrupt is still pending can hang HP machines with buggy SAL_CACHE_FLUSH implementations. Provide a kernel command-line argument to allow users skip this check if desired. Using this parameter will force ia64_sal_cache_flush to call ia64_pal_cache_flush() instead of SAL_CACHE_FLUSH.

[IA64] workaround tiger ia64_sal_get_physical_id_info hang

2008-03-04T22:26:50Z

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.
