2018-04-26arch/x86: print cr2 value on every exceptionAaron Durbin
Even though most x86 systems don't run with paging on, it's helpful to always print it out for the ones that do without making a more complicated handler. New dump will look like the following: Unexpected Exception: 6 @ 10:7ab84be2 - Halting Code: 0 eflags: 00010006 cr2: 00000000 eax: 7abb80ec ebx: deadbeef ecx: 00000000 edx: 00000002 edi: 7abb3000 esi: 00000004 ebp: 7abb2fd8 esp: 7abb2fb0 7ab84ba0: 00 01 00 83 ec 0c 6a 39 7ab84ba8: e8 8a 02 01 00 e8 e1 08 7ab84bb0: 00 00 e8 4e 3d 00 00 59 7ab84bb8: 5b 52 50 e8 f5 3c 00 00 7ab84bc0: c7 04 24 0a 00 00 00 e8 7ab84bc8: 3c 3d 00 00 c7 04 24 80 7ab84bd0: 00 00 00 e8 5f 02 01 00 7ab84bd8: e8 1e 38 01 00 e8 7e 50 7ab84be0: 01 00 0f 0b bb 98 ec ba 7ab84be8: 7a 83 c4 10 8b 03 85 c0 7ab84bf0: 0f 84 be 00 00 00 83 78 7ab84bf8: 04 00 8d 50 08 75 0c 56 7ab84c00: 56 ff 30 52 e8 f8 fe ff 7ab84c08: ff eb 0a 51 51 ff 30 52 7ab84c10: e8 2e ff ff ff 83 c4 10 7ab84c18: 83 c3 04 eb cf 89 d8 e8 BUG=b:72728953 Change-Id: I0e87bbe776f77623ad8297f5d80167998daec6ed Signed-off-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: https://review.coreboot.org/25762 Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2018-04-26cpu/x86: add limited runtime identity page mappingAaron Durbin
When employing PAGING_IN_CACHE_AS_RAM more areas need to be mapped in at runtime. Therefore, paging_identity_map_addr() is added to support adding identity mappings. Because there are a fixed amount of pages in cache-as-ram paging only the existing paging structures can be used. As such that's a limitation on what regions and length one can map. Using util/x86/x86_page_tables.go to generate page tables will always populate all the page directory pages. Therefore, 2MiB mappings are easy to map in.

2018-04-25arch/x86: add support for cache-as-ram pagingAaron Durbin
Processors, such as glk, need to have paging enabled while in cache-as-ram mode because the front end is agressive about fetching lines into the L1I cache. If the line is dirty and in the L1D then it writes it back to "memory". However, in this case there is no backing store so the cache-as-ram data that was written back transforms to all 0xff's when read back in causing corruption. In order to mitigate the failure add x86 architecture support for enabling paging while in cache-as-ram mode. A Kconfig variable, NUM_CAR_PAGE_TABLE_PAGES, determines the number of pages to carve out for page tables within the cache-as-ram region. Additionally, the page directory pointer table is also carved out of cache-as-ram. Both areas are allocated from the persist-across-stages region of cache-as-ram so all stages utilizing cache-as-ram don't corrupt the page tables. The two paging-related areas are loaded by calling paging_enable_for_car() with the names of cbfs files to load the initial paging structures from.

2018-02-16x86/mtrr: Enable Rd/WrDram mod in AMD fixed MTRRsMarshall Dawson
AMD's fixed MTRRs have RdDram and WrDram bits that route memory accesses to DRAM vs. MMIO. These are typically hidden for normal operation by clearing SYS_CFG[19] (MtrrFixDramModEn). According to BKDGs and AMD64 Programmer's Manual vol 2, this bit is clear at reset, should be set for configuration during POST, then cleared for normal operation. Attempting to modify the RdDram and WrDram settings without unhiding them causes a General Protection Fault. Add functions to enable and disable MtrrFixDramModEn. Unhide/hide as necessary when copying or writing the fixed MTRRs. Finally, modify sipi_vector.S to enable the bits prior to writing the fixed MTRRs and disable when complete. This functionality is compiled out on non-AMD platforms.

The original purpose of adjust_cpu_apic_entry() was to set up an APIC map. That map was effectively only used for mapping *default* APIC id to CPU number in the SMM handler. The normal AP startup path didn't need this mapping because it was whoever won the race got the next cpu number. Instead of statically calculating (and wrong) just initialize the default APIC id map when the APs come online. Once the APs are online the SMM handler is loaded and the mapping is utilized.

This patch adds the common acpi code.ACPI code is very similar accross different intel chipsets.This patch is an effort to move those code in common place so that it can be shared accross different intel platforms instead of duplicating for each platform. We are removing the common acpi files in src/soc/intel/common. This removes the acpi.c file which was previously in src/soc/common/acpi. The config for common acpi is SOC_INTEL_COMMON_BLOCK_ACPI which can be defined in SOC's Kconfig file in order to use the common ACPI code. This patch also includes the changes in APL platform to use the common ACPI block. TEST= Tested the patch as below: 1.Builds and system boots up with the patch. 2.Check all the ACPI tables are present in /sys/firmware/acpi/tables 3.Check SCI's are properly working as we are modifying the function to override madt. 4.Extract acpi tables like DSDT,APIC, FACP, FACS and decompile the by iasl and compare with good known tables. 5.Execute the extracted tables in aciexec to check acpi methods are working properly.

2016-11-12cpu/x86/mtrr: allow temporary MTRR range during corebootAaron Durbin
Certain platforms have a poorly performing SPI prefetcher so even if accessing MMIO BIOS once the fetch time can be impacted. Payload loading is one example where it can be impacted. Therefore, add the ability for a platform to reconfigure the currently running CPU's variable MTRR settings for the duration of coreboot's execution. The function mtrr_use_temp_range() is added which uses the previous MTRR solution as a basis along with a new range and type to use. A new solution is calculated with the updated settings and the original solution is put back prior to exiting coreboot into the OS or payload. Using this patch on apollolake reduced depthcharge payload loading by 75 ms.

2016-07-27cpu/x86: Support CPUs without rdmsr/wrmsr instructionsLee Leahy
Quark does not support the rdmsr and wrmsr instructions. In this case use a SOC specific routine to support the setting of the MTRRs. Migrate the code from FSP 1.1 to be x86 CPU common. Since all rdmsr/wrmsr accesses are being converted, fix the build failure for quark in lib/reg_script.c. Move the soc_msr_x routines and their depencies from romstage/mtrr.c to reg_access.c.

2016-06-22Ignore RAMTOP for MTRRsKyösti Mälkki
Without RELOCATABLE_RAMSTAGE have WB cache large enough to cover the greatest ramstage needs, as there is no benefit of trying to accurately match the actual need. Choose this to be bottom 16MiB. With RELOCATABLE_RAMSTAGE write-back cache of low ram is only useful for bottom 1MiB of RAM as a small part of this gets used during SMP initialisation before proper MTRR setup.

2016-05-04cpu/x86: combine multiprocessor and SMM initializationAaron Durbin
In order to reduce code duplication provide a common flow through callback functions that performs the multiprocessor and optionally SMM initialization. The existing MP flight records are utilized but a common flow is provided such that the chipset/cpu only needs to provide a mp_ops structure which has callbacks to gather info and provide hooks at certain points in the sequence. All current users of the MP code can be switched over to this flow since there haven't been any flight records that are overly complicated and long. After the conversion has taken place most of the surface area of the MP API can be hidden away within the compilation unit proper.

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.
