2009-01-29x86: move mach-default/*.h files to asm/Ingo Molnar
We are getting rid of subarchitecture support - move the hook files to asm/. (These are now stale and should be replaced with more explicit runtime mechanisms - but the transition is simpler this way.) Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86, smp: remove mach_ipi.hIngo Molnar
Move mach_ipi.h definitions into genapic.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86: remove mach_apic.hIngo Molnar
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>
2009-01-28x86, smp: refactor ->wake_cpuIngo Molnar
- remove macro wrappers Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-01-28x86, smp: eliminate asm/mach-default/mach_wakecpu.hIngo Molnar
Spread mach_wakecpu.h's definitions into apic.h and genapic.h and remove mach_wakecpu.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, smp: refactor ->inquire_remote_apic() methodsIngo Molnar
Nothing exciting - a few subarches dont want APIC remote reads to be performed - the others are content with the default method. - extend the generic code to handle NULL methods - clear out dummy methods and replace them with NULL - clean up: remove wrapper macros, etc. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, smp: refactor ->store/restore_NMI_vector() methodsIngo Molnar
Only NUMAQ does something substantial here, because it initializes via NMIs (not via INIT as standard SMP startup) - so it needs to store and restore the NMI vector. - extend the generic code to handle NULL methods - clear out dummy methods and replace them with NULL - clean up: remove wrapper macros, etc. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, smp: refactor ->smp_callin_clear_local_apic() methodsIngo Molnar
Only NUMAQ does something substantial here, because it initializes via NMIs (not via INIT as standard SMP startup) - so it needs to reset the APIC. - extend the generic code to handle NULL methods - clear out dummy methods and replace them with NULL - clean up: remove wrapper macros, etc. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, smp: refactor ->wait_for_init_deassert()Ingo Molnar
- spread out the namespace on a per APIC driver basis - handle a NULL ->wait_for_init_deassert() as a 'dont wait' default method - remove NUMAQ and Summit handlers Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: set ->trampoline_phys_low/high on 64-bit tooIngo Molnar
64-bit x86 has zero for ->trampoline_phys_low/high, but the smpboot code can use these values - so it's better to set them up to their correct values. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, smp: clean up ->trampoline_phys_low/high handlingIngo Molnar
- spread out the namespace on a per apic driver basis - remove wrapper macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: untangle the send_IPI_*() jungleIngo Molnar
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>
2009-01-28x86, apic: refactor ->cpu_mask_to_apicid*()Ingo Molnar
- spread out the namespace on a per driver basis - clean up the functions - get rid of macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: get rid of *_APIC_ID_MASK definitionsIngo Molnar
Impact: cleanup Remove the *_APIC_ID_MASK subarch definitions and move them straight to the genapic driver initialization code. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: refactor ->apic_id_mask & APIC_ID_MASKIngo Molnar
- spread out the namespace on a per driver basis - get rid of wrapper macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: refactor ->get_apic_id() & GET_APIC_ID()Ingo Molnar
- spread out the namespace on a per driver basis - get rid of macro wrappers - small cleanups Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: consolidate the ->mps_oem_check() codeIngo Molnar
- spread out the mps_oem_check() namespace on a per APIC driver basis Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: refactor ->phys_pkg_id()Ingo Molnar
Refactor the ->phys_pkg_id() methods: - namespace separation - macro wrapper removal - open-coded calls to the methods in the generic code Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: unify phys_pkg_id()Ingo Molnar
- unify the call signature of 64-bit to that of 32-bit - clean up the types all around - clean up namespace contamination Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: refactor ->enable_apic_mode() subarch methodsIngo Molnar
Only ES7000 has a real ->enable_apic_mode() method, the other subarchitectures define it but keep it empty. So mark the vector as NULL, extend the generic code to handle NULL -setup_portio_remap() entries and remove all the empty handlers. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: refactor ->check_phys_apicid_present() subarch methodsIngo Molnar
- spread out the namespace to per driver methods - extend it to 64-bit as well so that we can use apic->check_phys_apicid_present() unconditionally Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: refactor ->setup_portio_remap() subarch methodsIngo Molnar
Only NUMAQ has a real ->setup_portio_remap() method, the other subarchitectures define it but keep it empty. So mark the vector as NULL, extend the generic code to handle NULL -setup_portio_remap() entries and remove all the empty handlers. Also move the NUMAQ method from the header file into the apic driver .c file. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up ->apicid_to_cpu_present()Ingo Molnar
- separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up ->cpu_present_to_apicid()Ingo Molnar
- separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up ->cpu_to_logical_apicid()Ingo Molnar
- separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up ->apicid_to_node()Ingo Molnar
- separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: streamline the ->multi_timer_check() quirkIngo Molnar
only NUMAQ uses this quirk: to prevent the timer IRQ from being added on secondary nodes. All other genapic templates can have a NULL ->multi_timer_check() callback. Also, extend the generic code to treat a NULL pointer accordingly. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up ->setup_apic_routing()Ingo Molnar
- separate the namespace - remove macros - remove namespace clash on 64-bit Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up ->ioapic_phys_id_map()Ingo Molnar
- separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up ->init_apic_ldr()Ingo Molnar
- separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up ->vector_allocation_domain()Ingo Molnar
- separate the namespace - remove macros - move the default vector-allocation-domain to mach-generic - fix whitespace damage Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove no_balance_irq and no_ioapic_check flagsIngo Molnar
These flags are completely unused. (the in-kernel IRQ balancer has been removed from the upstream kernel.) Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up check_apicid*() callbacksIngo Molnar
Clean up these methods - to make it clearer which function is used in which case. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: clean up esr_disable() methodsIngo Molnar
Impact: cleanup Most subarchitectures want to disable the APIC ESR (Error Status Register), because they generally have hardware hacks that wrap standard CPUs into a bigger system and hence the APIC bus is quite non-standard and weirdnesses (lockups) have been seen with ESR reporting. Remove the esr_disable macros and put the desired flag into each subarchitecture's genapic template directly. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up / remove TARGET_CPUSIngo Molnar
Impact: cleanup use apic->target_cpus() directly instead of the TARGET_CPUS wrapper. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up target_cpus methodsIngo Molnar
Impact: cleanup Clean up all the target_cpus() namespace overlap that exists between bigsmp, es7000, mach-default, numaq and summit - by separating the different functions into different names. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove IRQ_DEST_MODEIngo Molnar
Remove leftover definition. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove DEFAULT_IRQ_DELIVERY_MODE and DEFAULT_IRQ_DEST_MODEIngo Molnar
Impact: cleanup They were only used in a single place and obscured the apic_default template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove IRQ_DEST_MODE / IRQ_DELIVERY_MODEIngo Molnar
Remove the wrapper macros IRQ_DEST_MODE and IRQ_DELIVERY_MODE. The typical 32-bit and the 64-bit build all dereference via the genapic, so it's pointless to hide that indirection via these ugly macros. Furthermore, it also obscures subarchitecture details. So replace it with apic->irq_dest_mode / etc. accesses. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, genapic: rename int_delivery_mode, et. al.Ingo Molnar
int_delivery_mode is supposed to mean 'interrupt delivery mode', but it's quite a misnomer as 'int' we usually think of as an integer type ... The standard naming for such attributes is 'irq' - so rename the following fields and macros: int_delivery_mode => irq_delivery_mode INT_DELIVERY_MODE => IRQ_DELIVERY_MODE int_dest_mode => irq_dest_mode INT_DEST_MODE => IRQ_DEST_MODE Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: clean up apic->apic_id_registered() methodsIngo Molnar
Impact: cleanup x86 subarchitectures each defined a "apic_id_registered()" method, which could be an inline function depending on which subarch we build for, and which was also the name of a genapic field. Untangle this namespace spaghetti by giving each of the instances a separate name. Also remove wrapper macro obfuscation. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: clean up apic->acpi_madt_oem_check methodsIngo Molnar
Impact: refactor code x86 subarchitectures each defined a "acpi_madt_oem_check()" method, which could be an inline function, or an extern, or a static function, and which was also the name of a genapic field. Untangle this namespace spaghetti by setting ->acpi_madt_oem_check() to NULL on those subarchitectures that have no detection quirks, and rename the other ones (summit, es7000) that do. Also change default_acpi_madt_oem_check() to handle NULL entries, and clean its control flow up as well. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: rename 'genapic' to 'apic'Ingo Molnar
Rename genapic-> to apic-> references because in a future chagne we'll open-code all the indirect calls (instead of obscuring them via macros), so we want this reference to be as short as possible. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-21x86: make x86_32 use tlb_64.cTejun Heo
Impact: less contention when issuing invalidate IPI, cleanup Make x86_32 use the same tlb code as 64bit. The 64bit code uses multiple IPI vectors for tlb shootdown to reduce contention. This patch makes x86_32 allocate the same 8 IPIs as x86_64 and share the code paths. Note that the usage of asmlinkage is inconsistent for x86_32 and 64 and calls for further cleanup. This has been noted with a FIXME comment in tlb_64.c. Signed-off-by: Tejun Heo <tj@kernel.org>
2009-01-12x86: fix apic.c build error on latest gitJaswinder Singh Rajput
Fix this by reintroducing asm/smp.h include in apic.c - later on I will fix this by removing non-smp data from smp.h Also fix the __inquire_remote_apic() prototype/inline. Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-04x86: rename mp_config_table to mpc_tableJaswinder Singh Rajput
Impact: cleanup, solve 80 columns wrap problems mp_config_table should be renamed to mpc_table. The reason: the 'c' in MPC already means 'config' - no need to repeat that in the type name. Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-12-18x86: fix cpu_mask_to_apicid_and to include cpu_online_maskMike Travis
Impact: fix potential APIC crash In determining the destination apicid, there are usually three cpumasks that are considered: the incoming cpumask arg, cfg->domain and the cpu_online_mask. Since we are just introducing the cpu_mask_to_apicid_and function, make sure it includes the cpu_online_mask in it's evaluation. [Added with this patch.] There are two io_apic.c functions that did not previously use the cpu_online_mask: setup_IO_APIC_irq and msi_compose_msg. Both of these simply used cpu_mask_to_apicid(cfg->domain & TARGET_CPUS), and all but one arch (NUMAQ[*]) returns only online cpus in the TARGET_CPUS mask, so the behavior is identical for all cases. [*: NUMAQ bug?] Note that alloc_cpumask_var is only used for the 32-bit cases where it's highly likely that the cpumask set size will be small and therefore CPUMASK_OFFSTACK=n. But if that's not the case, failing the allocate will cause the same return value as the default. Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
