2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

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.

Default CPU_ADDR_BITS is 36. For Atom (model_106cx) use 32. This model is known to fail execution-in-place (XIP) with the default 36. Pentium M should use 32, but doesn't even with this patch. Some Xeon and CORE(2) models should use 38 or 40.

2012-07-02remove CONFIG_SERIAL_CPU_INITSven Schnelle
The new broadcast code doesn't support serial init - if a CPU needs serial init, this should be handled in the model specific CPU init code.

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.

It's only used in the ACPI generator for Sandybridge/Ivybridge CPUs and the code can easily be changed to not rely on any Kconfig magic.

2012-04-26Revamp Intel microcode update codeStefan Reinauer
- add GPLv2 + copyright header after talking to Ron - "bits" in struct microcode served no real purpose but getting its address taken. Hence drop it - use asm volatile instead of __asm__ volatile - drop superfluous wrmsr (that seems to be harmless but is still wrong) in read_microcode_rev - use u32 instead of unsigned int where appropriate - make code usable both in bootblock and in ramstage - drop ROMCC style print_debug statements - drop microcode update copy in Sandybridge bootblock Change-Id: Iec4d5c7bfac210194caf577e8d72446e6dfb4b86 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/928 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
