litmus-rt.git/drivers/char/agp/Kconfig, branch 2011.1 The LITMUS^RT kernel. x86, k8 nb: Fix boot crash: enable k8_northbridges unconditionally on AMD systems 2010-03-13T07:36:16+00:00 Borislav Petkov bp@amd64.org 2010-03-12T14:43:03+00:00 0e152cd7c16832bd5cadee0c2e41d9959bc9b6f9 de957628ce7c84764ff41331111036b3ae5bad0f changed setting of the x86_init.iommu.iommu_init function ptr only when GART IOMMU is found. One side effect of it is that num_k8_northbridges is not initialized anymore if not explicitly called. This resulted in uninitialized pointers in <arch/x86/kernel/cpu/intel_cacheinfo.c:amd_calc_l3_indices()>, for example, which uses the num_k8_northbridges thing through node_to_k8_nb_misc(). Fix that through an initcall that runs right after the PCI subsystem and does all the scanning. Then, remove initialization in gart_iommu_init() which is a rootfs_initcall and we're running before that. What is more, since num_k8_northbridges is being used in other places beside GART IOMMU, include it whenever we add AMD CPU support. The previous dependency chain in kconfig contained K8_NB depends on AGP_AMD64|GART_IOMMU which was clearly incorrect. The more natural way in terms of hardware dependency should be AGP_AMD64|GART_IOMMU depends on K8_NB depends on CPU_SUP_AMD && PCI. Make it so Number One!

x86_init.iommu.iommu_init function ptr only when GART IOMMU is
found.

One side effect of it is that num_k8_northbridges
is not initialized anymore if not explicitly
called. This resulted in uninitialized pointers in
<arch/x86/kernel/cpu/intel_cacheinfo.c:amd_calc_l3_indices()>,
for example, which uses the num_k8_northbridges thing through

Fix that through an initcall that runs right after the PCI
subsystem and does all the scanning. Then, remove initialization
in gart_iommu_init() which is a rootfs_initcall and we're
running before that.

What is more, since num_k8_northbridges is being used in other
places beside GART IOMMU, include it whenever we add AMD CPU
support. The previous dependency chain in kconfig contained

K8_NB depends on AGP_AMD64|GART_IOMMU

which was clearly incorrect. The more natural way in terms of
hardware dependency should be

AGP_AMD64|GART_IOMMU depends on K8_NB depends on CPU_SUP_AMD &&
PCI. Make it so Number One!

There's no point in troubling the Alpha, IA-64, PowerPC and PARISC
people with SiS and VIA options.  Andrew thinks it helps find bugs,
but there's no evidence of that.
