[PATCH] ppc32: Put cache flush routines back into .relocate_code section

2006-03-01T22:36:31+00:00

In 2.6.14, we had the following definition of _GLOBAL() in include/asm-ppc/processor.h: #define _GLOBAL(n)\ .stabs __stringify(n:F-1),N_FUN,0,0,n;\ .globl n;\ n: In 2.6.15, as part of the great powerpc merge, we moved this definition to include/asm-powerpc/ppc_asm.h, where it appears (to 32-bit code) as: #define _GLOBAL(n) \ .text; \ .stabs __stringify(n:F-1),N_FUN,0,0,n;\ .globl n; \ n: Mostly, this is fine. However, we also have the following, in arch/ppc/boot/common/util.S: .section ".relocate_code","xa" [...] _GLOBAL(flush_instruction_cache) [...] _GLOBAL(flush_data_cache) [...] The addition of the .text section definition in the definition of _GLOBAL overrides the .relocate_code section definition. As a result, these two functions don't end up in .relocate_code, so they don't get relocated correctly, and the boot fails. There's another suspicious-looking usage at kernel/swsusp.S:37 that someone should look into. I did not exhaustively search the source tree, though. The following is the minimal patch that fixes the immediate problem. I could easily be convinced that the _GLOBAL definition should be modified to remove the ".text;" line either instead of, or in addition to, this fix.

[PATCH] ppc32: Re-add embed_config.c to ml300/ep405

2006-01-15T06:15:28+00:00

Commit 3e9e7c1d0b7a36fb8affb973a054c5098e27baa8 (ppc32: cleanup AMCC PPC40x eval boards to support U-Boot) broke the kernel for ML300 / EP405. It still compiles as there's a weak definition of the function in misc-embedded.c, but the kernel crashes as the bd_t fixup isn't performed.

[PATCH] powerpc: CPM2 interrupt handler failure after 100,000 interrupts

2005-12-20T04:39:33+00:00

The CPM2 interrupt handler does not return success to the IRQ subsystem, which causes it to kill the IRQ line after 100,000 interrupts. Signed-off-by: Edson Seabra Signed-off-by: Marcelo Tosatti Signed-off-by: Kumar Gala Signed-off-by: Paul Mackerras

[PATCH] ppc: ppc4xx_dma DMA_MODE_{READ,WRITE} fix

2005-12-16T22:43:05+00:00

DMA_MODE_{READ,WRITE} are declared in asm-powerpc/dma.h and their declarations there match the definitions. Old declarations in ppc4xx_dma.h are not right anymore (wrong type, to start with). Killed them, added include of asm/dma.h where needed. Signed-off-by: Al Viro Signed-off-by: Linus Torvalds

[PATCH] ppc32: set smp_tb_synchronized on UP with SMP kernel

2005-12-12T03:26:39+00:00

ppc32 kernel, when built with CONFIG_SMP and booted on a single CPU machine, will not properly set smp_tb_synchronized, thus causing gettimeofday() to not use the HW timebase and to be limited to jiffy resolution. This, among others, causes unacceptable pauses when launching X.org. Signed-Off-By: Johannes Berg Acked-by: Benjamin Herrenschmidt Signed-off-by: Andrew Morton Signed-off-by: Paul Mackerras

[PATCH] powerpc: Fix clock spreading setting on some powermacs

2005-12-12T03:16:09+00:00

The code that sets the clock spreading feature of the Intrepid ASIC must not be run on some machine models or those won't boot. This fixes it. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

ppc: Build in all three of powermac, PREP and CHRP support

2005-12-05T03:39:53+00:00

This reverts commit da0825fd201a03294dbf7f8f030676d608da122c, making it so that if you select CONFIG_PPC_MULTIPLATFORM you get support for PMAC, PREP and CHRP built in. The reason for not allowing PMAC, PREP and CHRP to be selected individually for ARCH=ppc is that there is too much interdependency between them in the platform support code. For example, CHRP uses the PMAC nvram code. Configuring with ARCH=powerpc does allow you to select support for PMAC and CHRP separately. Support for PREP is not there yet but should be there soon.

[PATCH] ppc32: fix treeboot image entrypoint

2005-12-01T23:48:56+00:00

Correctly specify treeboot based image entrypoint. Currently makefile uses $(ENTRYPOINT) which isn't defined anywhere. Each board port sets entrypoint-$(CONFIG_BOARD_NAME) instead. Without this patch I cannot boot Ocotea (PPC440GX eval board) anymore. I was getting random "OS panic" errors from OpenBIOS for a while, but with current kernel I get them all the time (probably because image became bigger).
