[PATCH] ia64 uncached alloc This patch contains the ia64 uncached page allocator and the generic allocator (genalloc). The uncached allocator was formerly part of the SN2 mspec driver but there are several other users of it so it has been split off from the driver. The generic allocator can be used by device driver to manage special memory etc. The generic allocator is based on the allocator from the sym53c8xx_2 driver. Various users on ia64 needs uncached memory. The SGI SN architecture requires it for inter-partition communication between partitions within a large NUMA cluster. The specific user for this is the XPC code. Another application is large MPI style applications which use it for synchronization, on SN this can be done using special 'fetchop' operations but it also benefits non SN hardware which may use regular uncached memory for this purpose. Performance of doing this through uncached vs cached memory is pretty substantial. This is handled by the mspec driver which I will push out in a seperate patch. Rather than creating a specific allocator for just uncached memory I came up with genalloc which is a generic purpose allocator that can be used by device drivers and other subsystems as they please. For instance to handle onboard device memory. It was derived from the sym53c7xx_2 driver's allocator which is also an example of a potential user (I am refraining from modifying sym2 right now as it seems to have been under fairly heavy development recently). On ia64 memory has various properties within a granule, ie. it isn't safe to access memory as uncached within the same granule as currently has memory accessed in cached mode. The regular system therefore doesn't utilize memory in the lower granules which is mixed in with device PAL code etc. The uncached driver walks the EFI memmap and pulls out the spill uncached pages and sticks them into the uncached pool. Only after these chunks have been utilized, will it start converting regular cached memory into uncached memory. Hence the reason for the EFI related code additions.

[IA64] esi-support Add support for making ESI calls [1]. ESI stands for "Extensible SAL specification" and is basically a way for invoking firmware subroutines which are identified by a GUID. I don't know whether ESI is used by vendors other than HP (if you do, please let me know) but as firmware "backdoors" go, this seems one of the cleaner methods, so it seems reasonable to support it, even though I'm not aware of any publicly documented ESI calls. I'd have liked to make the ESI module completely stand-alone, but unfortunately that is not easily (or not at all) possible because in order to make ESI calls in physical mode, a small stub similar to the EFI stub is needed in the kernel proper. I did try to create a stub that would work in user-level, but it quickly got ugly beyond recognition (e.g., the stub had to make assumptions about how the module-loader generated call-stubs work) and I didn't even get it to work (that's probably fixable, but I didn't bother because I concluded it was too ugly anyhow). While it's not terribly elegant to have kernel code which isn't actively used in the kernel proper, I think it might be worth making an exception here for two reasons: the code is trivially small (all that's really needed is esi_stub.S) and by including it in the normal kernel distro, it might encourage other OEMs to also use ESI, which I think would be far better than each inventing their own firmware "backdoor". The code was originally written by Alex. I just massaged and packaged it a bit (and perhaps messed up some things along the way...). Changes since first version of patch that was posted to mailing list: * Export ia64_esi_call and ia64_esi_call_phys() as GPL symbols. * Disallow building esi.c as a module for now. Building as a module would currently lead to an unresolved reference to "sal_lock" on SMP kernels because that symbol doesn't get exported. * Export esi_call_phys() only if ESI is enabled. * Remove internal stuff from esi.h and add a "proc_type" argument to ia64_esi_call() such that serialization-requirements can be expressed (ESI follows SAL here, where procedure calls may have to be serialized, are MP-safe, or MP-safe andr reentrant).
