45890f6d - ARC: mm: HIGHMEM: kmap API implementation

Mon, 09 Mar 2015 13:23:49 +0000

ARC: mm: HIGHMEM: kmap API implementationImplement kmap* API for ARC.This enables - permanent kernel maps (pkmaps): :kmap() API - fixmap : kmap_atomic()We use a very simple/uniform approach for both (unlike some of the otherarches). So fixmap doesn't use the customary compile time address stuff.The important semantic is sleep'ability (pkmap) vs. not (fixmap) whichthe API guarantees.Note that this patch only enables highmem for subsequent PAE40 supportas there is no real highmem for ARC in pure 32-bit paradigm as explainedbelow.ARC has 2:2 address split of the 32-bit address space with lower halfbeing translated (virtual) while upper half unstranslated(0x8000_0000 to 0xFFFF_FFFF). kernel itself is linked at base ofunstranslated space (i.e. 0x8000_0000 onwards), which is mapped to sayDDR 0x0 by external Bus Glue logic (outside the core). So kernel canpotentially access 1.75G worth of memory directly w/o need for highmem.(the top 256M is taken by uncached peripheral space from 0xF000_0000 to0xFFFF_FFFF)In PAE40, hardware can address memory beyond 4G (0x1_0000_0000) whilethe logical/virtual addresses remain 32-bits. Thus highmem is requiredfor kernel proper to be able to access these pages for it's own purposes(user space is agnostic to this anyways).Signed-off-by: Alexey Brodkin Signed-off-by: Vineet Gupta List of files: /linux-6.15/arch/arc/mm/Makefile

cfdbc2e1 - ARC: Build system: Makefiles, Kconfig, Linker script

Fri, 18 Jan 2013 09:42:20 +0000

ARC: Build system: Makefiles, Kconfig, Linker scriptArnd in his review pointed out that arch Kconfig organisation has severaldeficiencies:* Build time entries for things which can be runtime extracted from DT (e.g. SDRAM size, core clk frequency..)* Not multi-platform-image-build friendly (choice .. endchoice constructs)* cpu variants support (750/770) is exclusive.The first 2 have been fixed in subsequent patches.Due to the nature of the 750 and 770, it is not possible to build forboth together, w/o special runtime glue code which would hurtperformance.Signed-off-by: Vineet Gupta Cc: Arnd Bergmann Cc: Sam Ravnborg Acked-by: Sam Ravnborg List of files: /linux-6.15/arch/arc/mm/Makefile
