【记录】Ubuntu下用arm-xscale-linux-gnueabi交叉编译linux内核linux-2.6.19.1
期间，已经载入了默认的pxa的配置了。
现在去用make menuconfig确认一下，学习一下其已有配置。
【折腾过程】
1.make menuconfig后，主界面的配置：
文字版：

2.再继续看看子菜单Code maturity level options：
文字：

3.General setup：
文字：

│ │ |

4.Loadable module support
配置：
┌───────────────────────────────── Loadable module support
│ │ [*] Enable loadable module support │ │
│ │ [ ] Module unloading │ │
│ │ [ ] Module versioning support │ │
│ │ [ ] Source checksum for all modules │ │
│ │ [ ] Automatic kernel module loading |
截图：
5.Block layer
配置：
───────────────────────────────────────────────────────────────────────────────────────────────
┌─────────────────────────────────────── Block layer
│ │ — Enable the block layer │ │
│ │ [ ] Support for tracing block io actions │ │
│ │ IO Schedulers —> │ │
│ │ │ │
│ │ |
截图：
6.System Type
配置：
┌─────────────────────────────────────── System Type
│ │ ARM system type (PXA2xx-based) —> │ │
│ │ Intel PXA2xx Implementations —> │ │
│ │ — Processor Type │ │
│ │ — Processor Features │ │
│ │ [ ] Support Thumb user binaries │ │
│ │ [ ] Disable D-Cache (C-bit) |
截图：
其下的：
Intel PXA2xx Implementations
去看了看其子菜单：
┌────────────────────────────── Intel PXA2xx Implementations
│ │ Select target board (LogicPD PXA270 Card Engine Development Platform) —> |
配置：
┌────────────────────────────── Intel PXA2xx Implementations
│ │ Select target board (LogicPD PXA270 Card Engine Development Platform) —>│ │ |
而对于：
LogicPD PXA270 Card Engine Development Platform
去查了查，发现：
的确是有对应的板子的：
PXA270 Card Engine
其常见配置为：
PXA270, 520 MHz, 64 MB SDRAM, 32 MB NOR flash, Ethernet, audio, touch |
然后也找到了对应的内核中的相关配置：
if ARCH_PXA
的：
config MACH_LOGICPD_PXA270
bool "LogicPD PXA270 Card Engine Development Platform"
select PXA27x
select HAVE_PWM
select PXA_HAVE_BOARD_IRQS
7.Bus support
配置：
────────────────────────────────────────────────────────────────────────────────────────────────
┌─────────────────────────────────────── Bus support
│ │ PCCARD (PCMCIA/CardBus) support —> |
截图：
8.Kernel Features
截图：
配置：
┌───────────────────────────────────── Kernel Features
│ │ [*] Preemptible Kernel (EXPERIMENTAL) │ │
│ │ [ ] Dynamic tick timer │ │
│ │ [ ] Use the ARM EABI to compile the kernel │ │
│ │ Memory model (Flat Memory) —> │ │
│ │ [ ] 64 bit Memory and IO resources (EXPERIMENTAL) |
注意：
此处默认是没有选中EABI的：
“Use the ARM EABI to compile the kernel”
对应的解释是：
┌───────────────────────── Use the ARM EABI to compile the kernel CONFIG_AEABI:
This option allows for the kernel to be compiled using the latest ARM ABI (aka EABI). This is only useful if you are using a user space environment that is also compiled with EABI.
Since there are major incompatibilities between the legacy ABI and
EABI, especially with regard to structure member alignment, this option also changes the kernel syscall calling convention to
disambiguate both ABIs and allow for backward compatibility support (selected with CONFIG_OABI_COMPAT).
To use this you need GCC version 4.0.0 or later.
Symbol: AEABI [=n]
Prompt: Use the ARM EABI to compile the kernel Defined at arch/arm/Kconfig:530
Location: -> Kernel Features |
而我此处的交叉编译器是eabi的，不知道后期编译会不会出错。。

【总结】
就是全部的配置了。
暂时，先不去修改配置。包括那个EABI。等真的出问题了。再去修改。
