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, ES7000: consolidate the APIC codeIngo Molnar
Consolidate all the ES7000 APIC code into arch/x86/mach-generic/es7000.c. With this ES7000 ceases to rely on any subarchitecture include files. 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: remove ->restore_NMI_vector()Ingo Molnar
Nothing actually restores the NMI vector - so remove this logic altogether. 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, mpparse: call the generic quirk handlers earlyIngo Molnar
Call all the registered MPS quirk handlers early. These methods scan low RAM typically for specific signatures so are safe to be called early. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, smp: clean up mps_oem_check()Ingo Molnar
Impact: cleanup - allow NULL ->mps_oem_check() entries - clean up the code flow 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, es7000: clean up es7000_enable_apic_mode()Ingo Molnar
- eliminate the needless es7000_enable_apic_mode() complication which was not apparent prior the namespace cleanups - clean up the control flow in es7000_enable_apic_mode() - other cleanups 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, apic: rename genapic::apic_destination_logical to genapic::dest_logicalIngo Molnar
This field name was unreasonably long - shorten it. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: clean up the APIC_DEST_LOGICAL logicIngo Molnar
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>
2009-01-28x86: rename ->ESR_DISABLE to ->disable_esrIngo Molnar
the ->ESR_DISABLE shouting variant was used to enable the esr_disable macro wrappers. Those ugly macros are removed now so we can rename ->ESR_DISABLE to ->disable_esr 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 ES7000_IRQ_DELIVERY_MODE and ES7000_IRQ_DEST_MODEIngo Molnar
Impact: cleanup They were only used in a single place and obscured the apic_es7000 driver template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove BIGSMP_IRQ_DELIVERY_MODE and BIGSMP_IRQ_DEST_MODEIngo Molnar
Impact: cleanup They were only used in a single place and obscured the apic_bigsmp driver template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove NUMAQ_IRQ_DELIVERY_MODE and NUMAQ_IRQ_DEST_MODEIngo Molnar
Impact: cleanup They were only used in a single place and obscured the apic_numaq template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove SUMMIT_IRQ_DELIVERY_MODE and SUMMIT_IRQ_DEST_MODEIngo Molnar
Impact: cleanup They were only used in a single place and obscured the apic_summit template. 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>
