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>
2009-01-28x86: remove APIC_INIT / APICFUNC / IPIFUNCIngo Molnar
The APIC_INIT() / APICFUNC / IPIFUNC macros were ugly and obfuscated the true identity of various APIC driver methods. Now that they are not used anymore, remove them. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, genapic: cleanup 32-bit apic_summit templateIngo Molnar
Clean up the APIC driver template: - order fields properly - use the macro names explicitly (so that they can be renamed later) - fill in NULL entries as well Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-01-28x86: clean up apic_x2apic_clusterIngo Molnar
- reorder fields so that they appear in struct genapic field ordering - add zero-initialized fields too so that it's apparent which functionality is default / missing. Signed-off-by: Ingo Molnar <mingo@elte.hu>

- reorder fields so that they appear in struct genapic field ordering - add zero-initialized fields too so that it's apparent which functionality is default / missing. 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>
2009-01-28x86, genapic: provide IPI callbacks unconditionallyIngo Molnar
64-bit x86 uses the IPI callbacks even on UP - so provide them generally. Signed-off-by: Ingo Molnar <mingo@elte.hu>
