Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

kbuild: change kbuild to not rely on incorrect GNU make behavior The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

[PATCH] m32r: fix kernel entry address of vmlinux This patch fixes the kernel entry point address of vmlinux. The m32r kernel entry address is 0x08002000 (physical). But, so far, the ENTRY point written in vmlinux.lds.S was not point the correct kernel entry address. (before fix) $ objdump -x vmlinux vmlinux: file format elf32-m32r-linux vmlinux architecture: m32r2, flags 0x00000112: EXEC_P, HAS_SYMS, D_PAGED start address 0x88002090 /* NG */ : Sections: Idx Name Size VMA LMA File off Algn 0 .empty_zero_page 00001000 88001000 88001000 00001000 2**12 CONTENTS, ALLOC, LOAD, DATA 1 .boot 0000008c 88002000 88002000 00002000 2**2 CONTENTS, ALLOC, LOAD, READONLY, CODE 2 .text 001ab694 88002090 88002090 00002090 2**4 CONTENTS, ALLOC, LOAD, READONLY, CODE : (after fix) $ objdump -x vmlinux vmlinux: file format elf32-m32r-linux vmlinux architecture: m32r2, flags 0x00000112: EXEC_P, HAS_SYMS, D_PAGED start address 0x08002000 /* OK */ : This fix also remedies the following GDB error message (of gdb-6.4 or after) at the first operation of kernel debugging: "Previous frame identical to this frame (corrupt stack?)".

[PATCH] m32r: enable asm code optimization Add -O2 option to AFLAGS to enable asm code optimization for m32r. On m32r gas, "-m32r2 -O" option enables assembler's parallel code generation optimization for M32R2 ISA as a default. So, "-no-parallel" option is required explicitly for a cpu core with single instuction issuing, for example, VDEC2.
