[patch 0/6] x86: x2apic cluster optimizations and apic probe cleanups

[Suresh Siddha]

Ingo, Here is the updated patchset for optimizing IPI's in the
x2apic cluster mode aswell as clean the apic probe code by using
apicdriver section.

Previous version can be found at: https://lkml.org/lkml/2011/5/13/341

thanks,

[patch 1/6] x84_64, apic: use probe routines to simplify apic selection

[Suresh Siddha]

[-- Attachment #1: x64_apic_probe.patch --]
[-- Type: text/plain, Size: 4341 bytes --]

Use the unused probe routine in the apic driver to finalize the apic model
selection. This cleans up the default_setup_apic_routing() and this probe
routine in future can also be used for doing any apic model specific
initialisation.

[patch 3/6] x86, x2apic: track the x2apic cluster sibling map

[Suresh Siddha]

[-- Attachment #1: track_x2apic_cluster_info.patch --]
[-- Type: text/plain, Size: 3337 bytes --]

From: Cyrill Gorcunov <gorcunov@openvz.org>

In the case of x2apic cluster mode, we can group IPI register writes based on
the cluster group instead of individual per-cpu destination messages.

For this purpose, track the cpu's that belong to the same x2apic cluster.

[patch 4/6] x86, x2apic: minimize IPI register writes using cluster groups

[Suresh Siddha]

[-- Attachment #1: minimize_IPI_register_writes_using_cluster_groups.patch --]
[-- Type: text/plain, Size: 4412 bytes --]

From: Cyrill Gorcunov <gorcunov@openvz.org>

In the case of x2apic cluster mode we can group IPI register writes based
on the cluster group instead of individual per-cpu destination messages.

This reduces the apic register writes and reduces the amount of IPI messages
(in the best case we can reduce it by a factor of 16).

With this change, the cost of flush_tlb_others(), with the flush tlb IPI being
sent from a cpu in the socket-1 to all the logical cpus in socket-2 (on a
Westmere-EX system that has 20 logical cpus in a socket) is 3x times better now
(compared to the former 'send one-by-one' algorithm).

[patch 6/6] x86, apic: use .apicdrivers section to find the list of apic drivers

[Suresh Siddha]

[-- Attachment #1: use_apicdrivers_section.patch --]
[-- Type: text/plain, Size: 16742 bytes --]

This will enable each apic driver to be self-contained and eliminate the need
for apic_probe[].

Apic probe will now depend on the order in which apic drivers are listed in
the .apicdrivers section. Ordering of apic driver files in the Makefile
and the macros apic_driver()/apic_drivers() help enforce the desired order.

This patch crashes one of my testboxes (AMD X2 whitebox, config attached). No 
crashlog.

The patch is also clearly too large and should be split up into 4 pieces:

 - there should be a patch adding the whole driver section thing and marking 
   all the existing APIC drivers with it

 - one patch adding the functions doing the new-style probing.

 - one patch flipping over from old-style to new-style probing

 - a final patch removing all the stale functions and marking the APIC driver
   probe functions static.

Thanks,

	Ingo

oops. obviously just testing on small and big servers was not enough :(

flat mode was broken, as it had null probe routine. Old code didn't have
flat mode listed in the apic probe array (as the flat mode was the
default option). Will fix it and split it into multiple patches.

thanks.

can you change to:

+	for (drv = __apicdrivers; drv < __apicdrivers_end; drv++) {
+		if ((*drv)->probe()) {
+			if (apic != *drv) {
+				apic = *drv;				
+				printk(KERN_INFO "Changing APIC routing to %s.\n",
+				       apic->name);
+			}
 			break;
 		}
 	}

Thanks

Seems we miss ALIGN here, no?

	. = ALIGN(8);
