- bool "386"
- ---help---
- This is the processor type of your CPU. This information is used for
- optimizing purposes. In order to compile a kernel that can run on
- all x86 CPU types (albeit not optimally fast), you can specify
- "386" here.
-
- The kernel will not necessarily run on earlier architectures than
- the one you have chosen, e.g. a Pentium optimized kernel will run on
- a PPro, but not necessarily on a i486.
-
- Here are the settings recommended for greatest speed:
- - "386" for the AMD/Cyrix/Intel 386DX/DXL/SL/SLC/SX, Cyrix/TI
- 486DLC/DLC2, UMC 486SX-S and NexGen Nx586. Only "386" kernels
- will run on a 386 class machine.
- - "486" for the AMD/Cyrix/IBM/Intel 486DX/DX2/DX4 or
- SL/SLC/SLC2/SLC3/SX/SX2 and UMC U5D or U5S.
- - "586" for generic Pentium CPUs lacking the TSC
- (time stamp counter) register.
- - "Pentium-Classic" for the Intel Pentium.
- - "Pentium-MMX" for the Intel Pentium MMX.
- - "Pentium-Pro" for the Intel Pentium Pro.
- - "Pentium-II" for the Intel Pentium II or pre-Coppermine Celeron.
- - "Pentium-III" for the Intel Pentium III or Coppermine Celeron.
- - "Pentium-4" for the Intel Pentium 4 or P4-based Celeron.
- - "K6" for the AMD K6, K6-II and K6-III (aka K6-3D).
- - "Athlon" for the AMD K7 family (Athlon/Duron/Thunderbird).
- - "Crusoe" for the Transmeta Crusoe series.
- - "Efficeon" for the Transmeta Efficeon series.
- - "Winchip-C6" for original IDT Winchip.
- - "Winchip-2" for IDT Winchip 2.
- - "Winchip-2A" for IDT Winchips with 3dNow! capabilities.
- - "GeodeGX1" for Geode GX1 (Cyrix MediaGX).
- - "CyrixIII/VIA C3" for VIA Cyrix III or VIA C3.
- - "VIA C3-2 for VIA C3-2 "Nehemiah" (model 9 and above).
-
- If you don't know what to do, choose "386".

-
-config MPENTIUMII
- bool "Pentium-II/Celeron(pre-Coppermine)"
- help
- Select this for Intel chips based on the Pentium-II and

- copy optimization, compiles the kernel with optimization flags
- tailored for the chip, and applies any applicable Pentium Pro
- optimizations.
-
-config MPENTIUMIII
- bool "Pentium-III/Celeron(Coppermine)/Pentium-III Xeon"

- Celeron-Coppermine core. This option enables use of some

- extensions.

- (not Pentium M) chips. This option enables compile flags
- optimized for the chip, uses the correct cache shift, and
- applies any applicable Pentium III optimizations.

- help
- Select this for an IDT Winchip-2A or 3. Linux and GCC

- and alignment reqirements. Also enable out of order memory
- stores for this CPU, which can increase performance of some
- operations.

-
-config MCYRIXIII
- bool "CyrixIII/VIA-C3"
- help
- Select this for a Cyrix III or C3 chip. Presently Linux and GCC
- treat this chip as a generic 586. Whilst the CPU is 686 class,
- it lacks the cmov extension which gcc assumes is present when
- generating 686 code.
- Note that Nehemiah (Model 9) and above will not boot with this
- kernel due to them lacking the 3DNow! instructions used in earlier
- incarnations of the CPU.
-
-config MVIAC3_2
- bool "VIA C3-2 (Nehemiah)"
- help
- Select this for a VIA C3 "Nehemiah". Selecting this enables usage
- of SSE and tells gcc to treat the CPU as a 686.
- Note, this kernel will not boot on older (pre model 9) C3s.

-config X86_GENERIC
- bool "Generic x86 support"
- help
- Instead of just including optimizations for the selected
- x86 variant (e.g. PII, Crusoe or Athlon), include some more
- generic optimizations as well. This will make the kernel
- perform better on x86 CPUs other than that selected.
-
- This is really intended for distributors who need more
- generic optimizations.
