From 76d08bb3f09054edc45326ce5c698a3f6c45f5d0 Mon Sep 17 00:00:00 2001 From: Tony Luck Date: Mon, 5 Jun 2006 13:54:14 -0700 Subject: [IA64] Add "model name" to /proc/cpuinfo Linux ia64 port tried to decode the processor family number to something human-readable, but Intel brandnames don't change synchronously with updates to the family number. Adopt a more i386-like approach and just print the family number in decimal. Add a new field "model name" that uses PAL_BRAND_INFO to find the official name for the cpu, or on older systems, falls back to using the well-known codenames (Merced, McKinley, Madison).

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).

I added a new struct, ieee80211softmac_bss_info, which is used for BSS-dependent variables like these. A new hook has been added (bssinfo_change), which allows the drivers to be notified when anything in bssinfo changes. I modified the txrates_change API to match the bssinfo_change API. The existing one is a little messy and the usefulness of providing the old rates is questionable (and can be implemented at driver level if really necessary). No drivers are using this API (yet), so this should be safe. Signed-off-by: Daniel Drake Acked-by: Johannes Berg Signed-off-by: John W.
