* x86, apic: move APIC drivers to arch/x86/kernel/apic/*Ingo Molnar2009-02-171-164/+0
| | | | | | | | | | | | | arch/x86/kernel/ is getting a bit crowded, and the APIC drivers are scattered into various different files. Move them to arch/x86/kernel/apic/*, and also remove the 'gen' prefix from those which had it. Also move APIC related functionality: the IO-APIC driver, the NMI and the IPI code.

* x86, apic: remove genapic.hIngo Molnar2009-02-171-1/+1
| | | | | | | | Impact: cleanup Remove genapic.h and remove all references to it. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: fold apic_ops into genapicYinghai Lu2009-02-171-1/+1
| | | | | | | | | | | | Impact: cleanup make it simpler, don't need have one extra struct. v2: fix the sgi_uv build Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: move default_ipi_xx back to ipi.cYinghai Lu2009-02-051-0/+108
| | | | | | | | | | | | | | | Impact: cleanup only leave _default_ipi_xx etc in .h Beyond the cleanup factor, this saves a bit of code size as well: text data bss dec hex filename 7281931 1630144 1463304 10375379 9e50d3 vmlinux.before 7281753 1630144 1463304 10375201 9e5021 vmlinux.after Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: seperate default_send_IPI_mask_sequence/allbutself from logicalYinghai Lu2009-01-301-137/+2
| | | | | | | | | | | | | | | Impact: 32-bit should use logical version there are two version: for default_send_IPI_mask_sequence/allbutself one in ipi.h and one in ipi.c for 32bit it seems .h version overwrote ipi.c for a while. restore it so 32 bit could use its old logical version. also remove dupicated functions in .c Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, smp: remove mach_ipi.hIngo Molnar2009-01-291-1/+0
| | | | | | Move mach_ipi.h definitions into genapic.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: remove mach_apic.hIngo Molnar2009-01-291-1/+1
| | | | | | | Spread mach_apic.h definitions into genapic.h. (with some knock-on effects on smp.h and apic.h.) Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: untangle the send_IPI_*() jungleIngo Molnar2009-01-281-13/+15
| | | | | | | | | | | | | | | | Our send_IPI_*() methods and definitions are a twisted mess: the same symbol is defined to different things depending on .config details, in a non-transparent way. - spread out the quirks into separately named per apic driver methods - prefix the standard PC methods with default_ - get rid of wrapper macro obfuscation - clean up various details Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up ->cpu_to_logical_apicid()Ingo Molnar2009-01-281-2/+2
| | | | | | | | - separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: rename genapic::apic_destination_logical to genapic::dest_logicalIngo Molnar2009-01-281-1/+1
| | | | | | This field name was unreasonably long - shorten it. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: clean up the APIC_DEST_LOGICAL logicIngo Molnar2009-01-281-1/+1
| | | | | | | | | | | | | | | Impact: cleanup The bigsmp and es7000 subarchitectures un-defined APIC_DEST_LOGICAL in a rather nasty way by re-defining it to zero. That is infinitely fragile and makes it very hard to see what to code really does in a given context. The very same constant has different meanings and values - depending on which subarch is enabled. Untangle this mess by never undefining the constant, but instead propagating the right values into the genapic driver templates. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: cosmetic changes apic-related files.Mike Travis2008-12-161-7/+7
| | | | | | | | This patch simply changes cpumask_t to struct cpumask and similar trivial modernizations. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>
* x86 smp: modify send_IPI_mask interface to accept cpumask_t pointersMike Travis2008-12-161-7/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup, change parameter passing * Change genapic interfaces to accept cpumask_t pointers where possible. * Modify external callers to use cpumask_t pointers in function calls. * Create new send_IPI_mask_allbutself which is the same as the send_IPI_mask functions but removes smp_processor_id() from list. This removes another common need for a temporary cpumask_t variable. * Functions that used a temp cpumask_t variable for: cpumask_t allbutme = cpu_online_map; cpu_clear(smp_processor_id(), allbutme); if (!cpus_empty(allbutme)) ... become: if (!cpus_equal(cpu_online_map, cpumask_of_cpu(cpu))) ... * Other minor code optimizations (like using cpus_clear instead of CPU_MASK_NONE, etc.) Applies to linux-2.6.tip/master.

* X86_SMP: ipi.c declare functions before they get usedJaswinder Singh2008-07-251-1/+2

* x86: APIC: remove apic_write_around(); use alternativesMaciej W. Rozycki2008-07-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use alternatives to select the workaround for the 11AP Pentium erratum for the affected steppings on the fly rather than build time. Remove the X86_GOOD_APIC configuration option and replace all the calls to apic_write_around() with plain apic_write(), protecting accesses to the ESR as appropriate due to the 3AP Pentium erratum. Remove apic_read_around() and all its invocations altogether as not needed. Remove apic_write_atomic() and all its implementing backends. The use of ASM_OUTPUT2() is not strictly needed for input constraints, but I have used it for readability's sake. I had the feeling no one else was brave enough to do it, so I went ahead and here it is. Verified by checking the generated assembly and tested with both a 32-bit and a 64-bit configuration, also with the 11AP "feature" forced on and verified with gdb on /proc/kcore to work as expected (as an 11AP machines are quite hard to get hands on these days). Some script complained about the use of "volatile", but apic_write() needs it for the same reason and is effectively a replacement for writel(), so I have disregarded it. I am not sure what the policy wrt defconfig files is, they are generated and there is risk of a conflict resulting from an unrelated change, so I have left changes to them out. The option will get removed from them at the next run. Some testing with machines other than mine will be needed to avoid some stupid mistake, but despite its volume, the change is not really that intrusive, so I am fairly confident that because it works for me, it will everywhere.
