2012-08-25MPTABLE: check for fixed IRQ entries on all pinsSven Schnelle
Don't derive the IRQ pin from the function number. Especially onboard chipset devices don't follow that rule. Instead check and add all fixed IRQ entries.

2012-07-13MPTAPLE: generate from devicetree.cbSven Schnelle
This patch adds support for autogenerating the MPTABLE from devicetree.cb. This is done by a write_smp_table() declared weak in mpspec.c. If the mainboard doesn't provide it's own function, this generic implementation is called. Syntax in devicetree.cb: ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN> The ioapic_irq directive can be used in pci and pci_domain devices. If there's no directive, the autogen code traverses the tree back to the pci_domain and stops at the first device which such a directive, and use that information to generate the entry according to PCI IRQ routing rules.

Linux 2.6.11 seems to require a certain order in CPUs listed in mptable, so enforce it. This was only done on arima/hdama, but now is generic. Unfortunately this is somewhat slow.

2011-10-13mptable: Refactor lintsrc generationPatrick Georgi
We copied pretty much the same code for generating mptable entries for local interrupts (with some notable exceptions). This change moves these lines into a generic function "mptable_lintsrc" and makes use of it in many places. The remaining uses of smp_write_lintsrc should be reviewed and replaced by mptable_lintsrc calls where possible, and smp_write_lintsrc made static. This patch was generated using Coccinelle: @@ expression mc; expression isa_bus; @@ -smp_write_lintsrc(mc, mp_ExtINT, MP_IRQ_TRIGGER_DEFAULT|MP_IRQ_POLARITY_DEFAULT, isa_bus, 0x0, MP_APIC_ALL, 0x0); -smp_write_lintsrc(mc, mp_NMI, MP_IRQ_TRIGGER_DEFAULT|MP_IRQ_POLARITY_DEFAULT, isa_bus, 0x0, MP_APIC_ALL, 0x1); +mptable_lintsrc(mc, isa_bus); @@ expression mc; expression isa_bus; @@ -smp_write_lintsrc(mc, mp_ExtINT, MP_IRQ_TRIGGER_EDGE|MP_IRQ_POLARITY_HIGH, isa_bus, 0x0, MP_APIC_ALL, 0x0); -smp_write_lintsrc(mc, mp_NMI, MP_IRQ_TRIGGER_EDGE|MP_IRQ_POLARITY_HIGH, isa_bus, 0x0, MP_APIC_ALL, 0x1); +mptable_lintsrc(mc, isa_bus); @m@ identifier mc; expression BUS; @@ -#define IO_LOCAL_INT(type, intr, apicid, pin) smp_write_lintsrc(mc, (type), MP_IRQ_TRIGGER_EDGE | MP_IRQ_POLARITY_HIGH, BUS, (intr), (apicid), (pin)); ... -IO_LOCAL_INT(mp_ExtINT, 0x0, MP_APIC_ALL, 0x0); -IO_LOCAL_INT(mp_NMI, 0x0, MP_APIC_ALL, 0x1); +mptable_lintsrc(mc, BUS); Change-Id: I97421f820cd039f5fd753cb0da5c1cca68819bb4 Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/244 Tested-by: build bot (Jenkins) Reviewed-by: Marc Jones <marcj303@gmail.com>
2010-12-16Get mptable OEM/product ID from kconfig variables.Uwe Hermann
We currently use "COREBOOT" unconditionally as the "OEM ID" in our mptable.c files, and hardcode the mainboard name in mptable.c like this: mptable_init(mc, "DK8-HTX ", LAPIC_ADDR); However, the spec says "OEM ID: A string that identifies the manufacturer of the system hardware." (Table 4-2, page 42) so "COREBOOT" doesn't match the spec, we should use the hardware vendor name. Thus, use CONFIG_MAINBOARD_VENDOR which we have already as the "OEM ID" (truncate/fill it to 8 characters as per spec). Also, use CONFIG_MAINBOARD_PART_NUMBER (the board name) as "product ID", and truncate/fill it to 12 characters as per spec, if needed. Abuild-tested.
