2016-03-08cpu/x86/mtrr: add helper function to detect variable MTRRsAaron Durbin
The current MTRR API doesn't allow one to detect variable MTRRs along with handling fixed MTRRs in one function call. Therefore, add x86_setup_mtrrs_with_detect() to perform the same actions as x86_setup_mtrrs() but always do the dynamic detection.

The previous usage of the intel microcode support supported using the library under ROMCC and ramstage. Allow for microcode support to be used in normal C-based romstage as well by: 1. Only using walkcbfs when ROMCC is defined. 2. Only using spinlocks if !__PRE_RAM__ The header file now unconditionally exposes the declarations of the supporting functions.

This patch adds CC6 power save support to the AMD Family 15h support code. As CC6 is a complex power saving state that relies heavily on CPU, northbridge, and southbridge cooperation, this patch alters significant amounts of code throughout the tree simultaneously. Allowing the CPU to enter CC6 allows the second level of turbo boost to be reached, and also provides significant power savings when the system is idle due to the complete core shutdown.

Add the timestamp tick frequency within the timestamp table so the cbmem utility doesn't try to figure it out on its own. Those paths still exist for x86 systems which don't provide tsc_freq_mhz(). All other non-x86 systems use the monotonic timer which has a 1us granularity or 1MHz. One of the main reasons is that Linux is reporting /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq as the true turbo frequency on turbo enables machines. This change also fixes the p-state values honored in cpufreq for turbo machines in that turbo p-pstates were reported as 100MHz greater than nominal.

2015-06-09cbmem: Unify CBMEM init tasks with CBMEM_INIT_HOOK() APIKyösti Mälkki
Squashed and adjusted two changes from chromium.git. Covers CBMEM init for ROMTAGE and RAMSTAGE. cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API There are several use cases for performing a certain task when CBMEM is first set up (usually to migrate some data into it that was previously kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them differently: timestamp migration is called explicitly from cbmem_initialize(), certain x86-chipset-specific tasks use the CAR_MIGRATION() macro to register a hook, and the CBMEM console is migrated through a direct call from romstage (on non-x86 and SandyBridge boards). This patch decouples the CAR_MIGRATION() hook mechanism from cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer description of what it really does. All of the above use cases are ported to this new, consistent model, allowing us to have one less line of boilerplate in non-CAR romstages. BRANCH=None BUG=None TEST=Built and booted on Nyan_Blaze and Falco with and without CONFIG_CBMEM_CONSOLE. Confirmed that 'cbmem -c' shows the full log after boot (and the resume log after S3 resume on Falco). Compiled for Parrot, Stout and Lumpy.

Oops. This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism to the cbmem_initialize() call in ramstage. The macro is split into explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as possible and prevent surprises (although just using a single macro and relying on the Makefiles to link an object into all appropriate stages would also work). This allows us to get rid of the explicit cbmemc_reinit() in ramstage (which I somehow accounted for in the last patch without realizing that timestamps work exactly the same way...), and replace the older and less flexible cbmem_arch_init() mechanism. Also added a size assertion for the pre-RAM CBMEM console to memlayout that could prevent a very unlikely buffer overflow I just noticed. BRANCH=None BUG=None TEST=Booted on Pinky and Falco, confirmed that ramstage timestamps once again show up. Compile-tested for Rambi and Samus.

2014-11-20AMD: Isolate AGESA and PI build environmentsKyösti Mälkki
To backport features introduced with recent Chromebooks and/or Intel boards in general, heavy work on the AMD AGESA platform infrastructure is required. With the AGESA PI available in binary form only, community members have little means to verify, debug and develop for the said platforms. Thus it makes sense to fork the existing agesawrapper interfaces, to give AMD PI platforms a clean and independent sandbox. New directory layout reflects the separation already taken place under 3rdparty/ and vendorcode/.

2014-11-14AMD (K8/fam10): Rewrite CAR migration in post_cache_as_ramKyösti Mälkki
Old routine copied all of CAR region as-is right below CONFIG_RAMTOP. Most of this region was reserved to interleave AP CPU address spaces and unused on BSP CPU. The only part of CAR region requiring a copy in RAM is the sysinfo structure. Improved routine changes this as follows: A region of size 'backup_size' below CONFIG_RAMTOP is cleared. In case of S3 resume, OS context from this region is first copied to high memory (CBMEM_ID_RESUME). At stack switch, CAR stack is discarded. Top of the stack for BSP is located at 'CONFIG_RAMTOP - car_size' for the remaining part of the romstage. This region is part of 'backup_size' and was zeroed before the switch took place. Before CAR is torn down the region of CAR_GLOBALS (and CAR_CBMEM), including the relevant sysinfo data for AP nodes memory training, is copied at 'CONFIG_RAMTOP - car_size'. NOTE: While CAR_GLOBAL variables are recovered, there are currently no means to calculate their offsets in RAM. NOTE: Boards with multiple CPU packages are likely already broken since bbc880ee amdk8/amdfam10: Use CAR_GLOBAL for sysinfo This moved the copy of sysinfo in RAM from above the stack to below the stack, but code for AP CPU's was not adjusted accordingly.

2014-08-14Intel: Add common header file for CAR setupEdward O'Callaghan
When passing '-ffreestanding' the 'main' romstage.c may no longer necessarily be considered the entry point. From the C specification in 5.1.2.1 Freestanding environment; "In a freestanding environment (in which C program execution may take place without any benefit of an operating system), the name and type of the function called at program startup are implementation-defined." Clang complains about these being missing as Clang is somewhat more strict about the spec than GNU/GCC is. An advantage here is that a different entry-point type-signature shall now be warned about at compile time.

This is the minimal setup needed to be able to execute SMI handlers. Only support for ASEG handlers is added, which should be sufficient for Trinity (up to 4 cores). There are a few hacks which need to be introduced in generic code in order to make this work properly, but these hacks are self-contained. They are a not a result of any special needs of this CPU, but rather from a poorly designed infrastructure. Comments are added to explain how such code could be refactored in the future.

2014-03-20rmodules: use rmodtool to create rmodulesAaron Durbin
Start using the rmodtool for generating rmodules. rmodule_link() has been changed to create 2 rules: one for the passed in <name>, the other for creating <name>.rmod which is an ELF file in the format of an rmodule. Since the header is not compiled and linked together with an rmodule there needs to be a way of marking which symbol is the entry point. __rmodule_entry is the symbol used for knowing the entry point. There was a little churn in SMM modules to ensure an rmodule entry point symbol takes a single argument.
