From f04e68e9e2a651b5db4d769d20d78d807426f109 Mon Sep 17 00:00:00 2001 From: Steven Sherk Date: Wed, 30 Jan 2013 16:02:14 -0700 Subject: Add MMCONF resource to AMD fam15 PCI_DOMAIN This is a port of the following: commit d5c998be99709c92f200b3b08aed2ca3fee2d519 The coreboot resource allocator doesn't respect resources claimed in the APIC_CLUSTER. Move the MMCONF resource to the PCI_DOMAIN to prevent overlap with PCI devices. original-Change-Id: I8541795f69bbdd9041b390103fb901d37e07eeb9 Signed-off-by: Marc Jones URL - http://review.coreboot.org/#/c/2167/ Change-Id: I6e585d5cf0d46bd58337a6801fb0690ab2dd000c Signed-off-by: Steven Sherk Reviewed-on: http://review.coreboot.org/2248 Tested-by: build bot (Jenkins) Reviewed-by: Marc Jones --- src/northbridge/amd/agesa/family15/northbridge.c | 32 +++++++++++++++--------- 1 file changed, 20 insertions(+), 12 deletions(-) (limited to 'src/northbridge') diff --git a/src/northbridge/amd/agesa/family15/northbridge.c b/src/northbridge/amd/agesa/family15/northbridge.c index 1adf714d19..1ac7e616f6 100644 --- a/src/northbridge/amd/agesa/family15/northbridge.c +++ b/src/northbridge/amd/agesa/family15/northbridge.c @@ -341,6 +341,20 @@ static void nb_read_resources(device_t dev) amdfam15_link_read_bases(dev, nodeid, link->link_num); } } + + /* + * This MMCONF resource must be reserved in the PCI_DOMAIN. + * It is not honored by the coreboot resource allocator if it is in + * the APIC_CLUSTER. + */ +#if CONFIG_MMCONF_SUPPORT + struct resource *resource = new_resource(dev, 0xc0010058); + resource->base = CONFIG_MMCONF_BASE_ADDRESS; + resource->size = CONFIG_MMCONF_BUS_NUMBER * 4096 * 256; + resource->flags = IORESOURCE_MEM | IORESOURCE_RESERVE | + IORESOURCE_FIXED | IORESOURCE_STORED | IORESOURCE_ASSIGNED; +#endif + } @@ -448,6 +462,12 @@ static void nb_set_resources(device_t dev) assign_resources(bus); } } + + /* Print the MMCONF region if it has been reserved. */ + res = find_resource(dev, 0xc0010058); + if (res) { + report_resource_stored(dev, res, " "); + } } static void northbridge_init(struct device *dev) @@ -1095,22 +1115,10 @@ static void cpu_bus_noop(device_t dev) static void cpu_bus_read_resources(device_t dev) { -#if CONFIG_MMCONF_SUPPORT - struct resource *resource = new_resource(dev, 0xc0010058); - resource->base = CONFIG_MMCONF_BASE_ADDRESS; - resource->size = CONFIG_MMCONF_BUS_NUMBER * 4096*256; - resource->flags = IORESOURCE_MEM | IORESOURCE_RESERVE | - IORESOURCE_FIXED | IORESOURCE_STORED | IORESOURCE_ASSIGNED; -#endif } static void cpu_bus_set_resources(device_t dev) { - struct resource *resource = find_resource(dev, 0xc0010058); - if (resource) { - report_resource_stored(dev, resource, " "); - } - pci_dev_set_resources(dev); } static struct device_operations cpu_bus_ops = { -- cgit v1.2.3
