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

2005-12-20T04:39:33Z

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

2005-12-16T22:43:05Z

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

2005-12-12T03:26:39Z

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

2005-12-12T03:16:09Z

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

2005-12-05T03:39:53Z

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

2005-12-01T23:48:56Z

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).

[PATCH] ppc32: Fix incorrect PCI frequency value

2005-12-01T23:48:56Z

The time to wait after deasserting PCI_RST has been counted with incorrect value - this patch fixes the issue. Signed-off-by: Vitaly Bordug Signed-off-by: Kumar Gala Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] ppc: fix floating point register corruption

2005-11-30T03:47:03Z

I recently discovered a bug on PPC which causes the floating point registers to get corrupted when CONFIG_PREEMPT=y. The problem occurred while running a multi threaded Java application that does floating point. The problem could be reproduced in anywhere from 2 to 6 hours. With the patch I have included below it ran for over a week without failure.

[PATCH] ppc: Export symbol needed by MOL

2005-11-29T02:23:28Z

Export symbol needed to allow MOL to run. This was changed to be inline in past and forgot to be change here. Signed-off-by: Paul Mackerras
