2010-11-13MTRR related improvements for AMD family 10h and family 0Fh systemsScott Duplichan
-- When building for UMA, reduce the limit for DRAM below 4GB from E0000000 to C0000000. This is needed to accomodate the UMA frame buffer. -- Correct problem where msr C0010010 bits 21 and 22 (MtrrTom2En and Tom2ForceMemTypeWB) are not set consistently across cores. -- Enable TOM2 only if DRAM is present above 4GB. -- Use AMD Tom2ForceMemTypeWB feature to avoid the need for variable MTRR ranges above 4GB. -- Add above4gb flag argument to function x86_setup_var_mtrrs. Clearing this flag causes x86_setup_var_mtrrs() to omit MTRR ranges for DRAM above 4GB. AMD systems use this option to conserve MTRRs. -- Northbridge.c change to deduct UMA memory from DRAM size reported by ram_resource. This corrects a problem where mtrr.c generates an unexpected variable MTRR range. -- Correct problem causing build failure when CONFIG_GFXUMA=1 and CONFIG_VAR_MTRR_HOLE=0. -- Reserve the UMA DRAM range for AMD K8 as is already done for AMD family 10h. Tested with mahogany on ECS A780G-GM with 2GB and 4GB. Tested with mahogany_fam10 on ECS A780G-GM with 2GB and 4GB.

2010-10-01Factor out common CAR asm snippets.Uwe Hermann
This makes the CAR implementations a lot more readable, shorter and easier to follow, and also reduces the amount of uselessly duplicated code. For example there are more than 12 open-coded "enable cache" instances spread all over the place (and 12 "disable cache" ones), multiple "enable mtrr", "save BIST", "restore BIST", etc. etc. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5902 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2010-10-01CAR simplifications, typos, readability improvements (trivial).Uwe Hermann
- Use some more #defines instead of hard-coding values. - Merge multiple movl/orl or movl/andl lines into one where possible. - Add some TODOs in places which seem to have either an incorrect code or incorrect comment. - Fix typos: s/for/from/, s/BSC/BSP/, s/size/carsize/.

2010-09-29Factor out fill_processor_name() and strcpy() functions.Uwe Hermann
The fill_processor_name() function was duplicated in multiple model_*_init.c files, move it into a new src/cpu/x86/name directory. The strcpy() function was also duplicated multiple times, move it to <string.h> where we already have similar functions.

2010-09-17AMD Fam10 code breaks with gcc 4.5.0.Scott Duplichan
Root cause: After function STOP_CAR_AND_CPU disables cache as ram, the cache as ram stack can no longer be used. Called functions must be inlined to avoid stack usage. Also, the compiler must keep local variables register based and not allocated them from the stack. With gcc 4.5.0, some functions declared as inline are not being inlined. This patch forces these functions to always be inlined by adding the qualifier __attribute__((always_inline)) to their declaration.

2010-08-03Drop the USE_PRINTK_IN_CAR option. It's a bogus decision to make for any user /Stefan Reinauer
board porter: printk should always be available in CAR mode. Also drop CONFIG_USE_INIT, it's only been selected on one ASROCK board but it's not been used there. Very odd. There is one usage of CONFIG_USE_INIT which was always off in src/cpu/intel/car/cache_as_ram.inc and we have to figure out what to do with those few lines.

2010-05-16Following patch reworks car_disable into C. Tested, works here. I comparedRudolf Marek
also the GCC generated code and it looks all right. Please test on some multicore CPU. I added the "memory" clobber to read_cr0 / write_cr0 function as it is in Linux Kernel. Seems that if this is missing, GCC is too smart and messes the order of reads/writes to CR0 (not tested if really a problem here, but be safe for future users of this function ;) Signed-off-by: Rudolf Marek <r.marek@assembler.cz> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5562 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

2007-12-19Changed the stop_this_cpu() to just hlt.Marc Jones
Removed local APIC INIT (don't worry the APIC and AP are still initialized). The local APIC INIT seemed to be the incorrect thing to do to stop an AP. The Intel Multiprocessor specification indicated that a vector should be set and a START should happen following an INIT. Then AP will execute the instructions pointed to by the vector. There is no vector or start in stop_this_cpu(). This seems to put the AP in an in-between state. In the case of Barcelona the AP's MSRs and PCI register are not accessible by the hardware debugger. The better solution seems to be to just put the AP in a hlt and allow the AP to go into C1. Then APIC managing software running on the BSP can program the AP as needed.
