x86, tracing: add notrace to asm-x86/linkage.h · 78a9909a

由 Ingo Molnar 提交于 4月 17, 2008

notrace signals that a function should not be traced. Most of the
time this is used by tracers to annotate code that cannot be
traced - it's in a volatile state (such as in user vdso context
or NMI context) or it's in the tracer internals.

  Date:   Wed Jan 30 13:32:40 2008 +0100

      x86: move X86_FEATURE_CONSTANT_TSC into early cpu feature detection

sets CONSTANT_TSC for intel cpus - but it is already set in init_intel().

don't need to set that two times in early_init_intel() and init_intel().
this patch removes the init_intel() one.

x86: apic_is_clustered_box for vsmp · f8fffa45

由 Yinghai Lu 提交于 2月 24, 2008

quad core 8 socket system will have apic id lifting.the apic id range could
be [4, 0x23]. and apic_is_clustered_box will think that need to three clusters
and that is larger than 2. So it is treated as a clustered_box.

and will get:

   Marking TSC unstable due to TSCs unsynchronized

even if the CPUs have X86_FEATURE_CONSTANT_TSC set.

this quick fix will check if the cpu is from AMD.

but vsmp still needs that checking...

this patch is fix to make sure that vsmp not to be passed.

x86: insert_resorce for lapic addr after e820_reserve_resources · 1e934dda

由 Yinghai Lu 提交于 2月 22, 2008

when comparing the e820 direct from BIOS, and the one by kexec:

 BIOS-provided physical RAM map:
- BIOS-e820: 0000000000000000 - 0000000000097400 (usable)

  BIOS-e820: 0000000100000000 - 0000004020000000 (usable)

found one entry about reserved is missing for the kernel by kexec.

it turns out init_apic_mappings is called before e820_reserve_resources
in setup_arch. but e820_reserve_resources is using request_resource.
it will not handle the conflicts.

there are three ways to fix it:

1. change request_resource in e820_reserve_resources to to insert_resource
2. move init_apic_mappings after e820_reserve_resources
3. use late_initcall to insert lapic resource.

this patch is using method 3, that is less intrusive.

in later version could consider to use method 1.

before patch
fed20000-ffffffff : PCI Bus #00
  fee00000-fee00fff : Local APIC
  fefff000-feffffff : pnp 00:09
  ff700000-ffffffff : reserved

with patch will get map in first kernel

fed20000-ffffffff : PCI Bus #00
  fee00000-fee00fff : Local APIC
    fee00000-fee00fff : reserved
  fefff000-feffffff : pnp 00:09

x86: make amd quad core 8 socket system not be clustered_box, #2 · 322850af

由 Yinghai Lu 提交于 2月 23, 2008

quad core 8 socket system will have apic id lifting.the apic id range could
be [4, 0x23]. and apic_is_clustered_box will think that need to three clusters
and that is large than 2. So it is treated as clustered_box.

and will get
