* [IA64-SGI] fix prom revision checks in SN kernelAaron Young2006-06-282-2/+2
| | | | | | | | | | | The following patch fixes two spots in the SN kernel that check a fixed prom revision number to determine prom feature support. These checks are only valid on shub1 systems. They are invalid on shub2 systems which have a different prom with different revision numbers. Signed-off-by: Aaron Young <ayoung@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| * [PATCH] change gen_pool allocator to not touch managed memoryDean Nelson2006-06-231-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the gen_pool allocator (lib/genalloc.c) to utilize a bitmap scheme instead of the buddy scheme. The purpose of this change is to eliminate the touching of the actual memory being allocated. Since the change modifies the interface, a change to the uncached allocator (arch/ia64/kernel/uncached.c) is also required. Both Andrey Volkov and Jes Sorenson have expressed a desire that the gen_pool allocator not write to the memory being managed.

* [IA64-SGI] - Reduce overhead of reading sn_topologyJack Steiner2006-04-271-2/+2
| | | | | | | | | | | | | | | MPI programs using certain debug options have a long startup time. This was traced to a "vmalloc/vfree" in the code that reads /proc/sgi_sn/sn_topology.

* [PATCH] EFI: keep physical table addresses in efi structureBjorn Helgaas2006-03-261-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Almost all users of the table addresses from the EFI system table want physical addresses. So rather than doing the pa->va->pa conversion, just keep physical addresses in struct efi. This fixes a DMI bug: the efi structure contained the physical SMBIOS address on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap() on a virtual address on ia64. This is essentially the same as an earlier patch by Matt Tolentino: http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2 except that this changes all table addresses, not just ACPI addresses. Matt's original patch was backed out because it caused MCAs on HP sx1000 systems. That problem is resolved by the ioremap() attribute checking added for ia64.

When performing such writes from the kernel this is not a problem, as a kernel thread will not migrate to another CPU during execution, and mmiowb() calls can guarantee write ordering when control of the IO resource is allowed to move between threads. However, when MMIO writes can be performed from user space (e.g. DRM) there are no such guarantees and mechanisms, as the process may context-switch at any time, and may migrate to a different CPU as part of the switch. For such programs/hardware to operate correctly, it is required that the MMIO writes from the old CPU be accepted by the IO hardware before subsequent writes from the new CPU can be issued. The following patch implements this behavior on SN2 by waiting for a Shub register to indicate that these writes have been accepted. This is placed in the context switch-in path, and only performs the wait when the newly scheduled task changes CPUs.

The first fix (now in 2.6.15) broke the delay loop into smaller, non-preemptible chunks, reenabling preemption between the chunks. This fix is flawed in that the total udelay is computed to be the sum of just the non-premptible while-loop pieces, i.e., not counting the time spent in the interim preemptible periods. If an interrupt or a migration occurs during one of these interim periods, then that time is invisible and only serves to lengthen the effective udelay(). This new fix backs out the current flawed fix and returns to a simple udelay(), fully preemptible and interruptible. It implements two simple alternative udelay() routines: one a default generic version that uses ia64_get_itc(), and the other an sn-specific version that uses that platform's RTC.
