2012-09-05buildsystem: Make CPU microcode updating more configurableAlexandru Gagniuc
This patch aims to improve the microcode in CBFS handling that was brought by the last patches from Stefan and the Chromium team. Choices in Kconfig - 1) Generate microcode from tree (default) - 2) Include external microcode file - 3) Do not put microcode in CBFS The idea is to give the user full control over including non-free blobs in the final ROM image. MICROCODE_INCLUDE_PATH Kconfig variable is eliminated. Microcode is handled by a special class, cpu_microcode, as such: cpu_microcode-y += microcode_file.c MICROCODE_IN_CBFS should, in the future, be eliminated. Right now it is needed by intel microcode updating. Once all intel cpus are converted to cbfs updating, this variable can go away. These files are then compiled and assembled into a binary CBFS file. The advantage of doing it this way versus the current method is that 1) The rule is CPU-agnostic 2) Gives user more control over if and how to include microcode blobs 3) The rules for building the microcode binary are kept in src/cpu/Makefile.inc, and thus would not clobber the other makefiles, which are already overloaded and very difficult to navigate.

2012-07-24CPU: Set flex ratio to nominal TDP ratio in bootblockDuncan Laurie
CPUs with configurable TDP will run the TSC at the max non-turbo ratio for the maximum TDP value, which can cause issues if another TDP is desired. To deal with this we set the flex ratio to the nominal TDP ratio early in the boot and then configure the Soft Reset Data registers so the PCH can tell the CPU what frequency to run at after a reset. This is done very early in the bootblock because it is necessary to reset the system after setting a flex ratio. The end result is that the TSC will now increment at the max non-turbo frequency for the nominal TDP. On some system with 1.8GHz CPU ensure that the kernel detects the CPU speed as ~1800mhz rather than ~2300mhz: > dmesg | grep "MHz processor" [ 0.004000] Detected 1795.801 MHz processor.

2012-07-24Remove code that enables/disables VMX in coreboot on chromebooks.Ronald G. Minnich
There are several reasons for this: 1. It's a core setting, not a platform setting, which is bizarre. But, we disable vmx via an SMI, and that only happens on core 0. Hence, the code did not correctly make the same settings on all cores- one had them disabled, the others were in an unknown state. When (e.g.) kvm started on a vmx-enabled core, then moved to a vmx-disabled core, the processor would reset *very* quickly. Changing this would be messy. 2. On the CPU on link, there is something about trying to set the lock bit that is getting a GPF. 3. It's the wrong place and time to set it. Once controlled, they can't be changed in the kernel. The kernel is what should control this feature, not the BIOS, as we have learned time and time again. If somebody is in as root and can start a VM, you have a lot more to worry about than someone starting a guest virtual machine.

2012-07-04Intel cpus: Extend cache to cover complete Flash DeviceKyösti Mälkki
CACHE_ROM_SIZE default is ROM_SIZE, the Flash device size set in menuconfig. This fixes a case where 8 MB SPI flash MTRR setup would not cover the bottom 4 MB when ramstage is decompressed. Verify CACHE_ROM_SIZE is power of two. One may set CACHE_ROM_SIZE==0 to disable this cache.

2012-07-04Intel model_106cx: change CAR to model_6exKyösti Mälkki
Diff between model_106cx and model_6ex CAR codes suggests currently used model_106cx CAR is not optimal - destination RAM and source ROM of ramstage copy_and_run are only partly set cacheable. It appears variable MTRR setting for XIP cache is left enabled on model_106cx code, where it should have extended to cover all of Flash.

A diff from model_6fx to model_106cx suggests there is little CORE2 specific code that was once considered useful to have.

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.
