2012-12-06Unify assembler function handlingStefan Reinauer
Instead of adding regparm(0) to each assembler function called by coreboot, add an asmlinkage macro (like the Linux kernel does) that can be different per architecture (and that is empty on ARM right now) Change-Id: I7ad10c463f6c552f1201f77ae24ed354ac48e2d9 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/1973 Reviewed-by: David Hendricks <dhendrix@chromium.org> Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-11-13Pass the CPU index as a parameter to startup.Ronald G. Minnich
This addition is in support of future multicore support in coreboot. It also will allow us to remove some asssembly code. The CPU "index" -- i.e., its order in the sequence in which cores are brought up, NOT its APIC id -- is passed into the secondary start. We modify the function to specify regparm(0). We also take this opportunity to do some cleanup: indexes become unsigned ints, not unsigned longs, for example. Build and boot on a multicore system, with pcserial enabled. Capture the output. Observe that the messages Initializing CPU #0 Initializing CPU #1 Initializing CPU #2 Initializing CPU #3 appear exactly as they do prior to this change.

2012-11-12Fix gcc-4.7 building problem.Han Shen
Applied function attribute to function definition to avoid 'conflicting type' warning. Function declaration is in src/include/cpu.h void secondary_cpu_init(unsigned int cpu_index)__attribute__((regparm(0))); But function definition in lapic_cpu_init.c is missing the "__attribute__" part.

2012-07-31Revert "Use broadcast SIPI to startup siblings"Sven Schnelle
This reverts commit 042c1461fb777e583e5de48edf9326e47ee5595f. It turned out that sending IPIs via broadcast doesn't work on Sandybridge. We tried to come up with a solution, but didn't found any so far. So revert the code for now until we have a working solution.

2012-07-02Use broadcast SIPI to startup siblingsSven Schnelle
The current code for initializing AP cpus has several shortcomings: - it assumes APIC IDs are sequential - it uses only the BSP for determining the AP count, which is bad if there's more than one physical CPU, and CPUs are of different type Note that the new code call cpu->ops->init() in parallel, and therefore some CPU code needs to be changed to address that. One example are old Intel HT enabled CPUs which can't do microcode update in parallel.

2012-04-27cpu/cpu.h: add ROMCC guardsStefan Reinauer
In order to use the generic microcode update code in the bootblock, cpu/cpu.h needs ROMCC guards. Also, delete the unused struct device declaration and move the struct bus declaration to where it's used.
