From 5ac6da669e2476dbdac89b357b05b5a79bc5b657 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Sat, 10 Feb 2007 01:43:14 -0800 Subject: [PATCH] Set CONFIG_ZONE_DMA for arches with GENERIC_ISA_DMA As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA channel management. Other functionality may still expect GFP_DMA to provide memory below 16M. So we need to make sure that CONFIG_ZONE_DMA is set independent of CONFIG_GENERIC_ISA_DMA. Undo the modifications to mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set theses explicitly in each arches Kconfig. Reviews must occur for each arch in order to determine if ZONE_DMA can be switched off. It can only be switched off if we know that all devices supported by a platform are capable of performing DMA transfers to all of memory (Some arches already support this: uml, avr32, sh sh64, parisc and IA64/Altix). In order to switch ZONE_DMA off conditionally, one would have to establish a scheme by which one can assure that no drivers are enabled that are only capable of doing I/O to a part of memory, or one needs to provide an alternate means of performing an allocation from a specific range of memory (like provided by alloc_pages_range()) and insure that all drivers use that call. In that case the arches alloc_dma_coherent() may need to be modified to call alloc_pages_range() instead of relying on GFP_DMA.

This saves another 4 kbytes on most platfoms (some reserve PAGE_SIZE for initramfs).

Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

-- cgit v1.2.3 From ab9367e38fa97c2ed7f72fd5fa29d0d70d58df89 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 12 Feb 2007 11:29:04 +0100 Subject: [POWERPC] ppc: Add support for AMCC Taishan 440GX eval board This patch adds support for the AMCC Taishan PPC440GX evaluation board. This is still an arch/ppc port. I'm aware that the move of 4xx to arch/powerpc is making good progress right now. So this patch is mainly intended to make the Taishan support available for the community right now.
