1) fix enable of power aware interrupt routing 2) set BIOS_RESET_CPL to 3 instead of 1 3) mirror PKG power limit values from MSR to MMIO on all SKUs 4) mirror DDR power limit values from MMIO to MSR 5) remove DMI settings that were from snb/ivb as they do not apply to haswell 1) verify power aware interrupt routing is working by looking in /proc/interrupts to see interrupts routed to both cores instead of always to core0 BEFORE: 58: 4943 0 PCI-MSI-edge ahci AFTER: 58: 4766 334 PCI-MSI-edge ahci 2) read back BIOS_RESET_CPL to verify it is == 3 localhost ~ # iotools mmio_read32 0xfed15da8 0x00000003 3) read PKG power limit from MMIO and verify it is the same as the MSR value localhost ~ # rdmsr 0 0x610 0x0000809600dc8078 localhost ~ # iotools mmio_read32 0xfed159a0 0x00dc8078 localhost ~ # iotools mmio_read32 0xfed159a4 0x00008096 4) read DDR power limit from MSR and verify it is the same as the MMIO value (note this is zero based on current MRC input) localhost ~ # rdmsr 0 0x618 0x0000000000000000 localhost ~ # iotools mmio_read32 0xfed158e0 0x00000000 localhost ~ # iotools mmio_read32 0xfed158e4 0x00000000 Change-Id: I6cc4c5b2a81304e9deaad8cffcaf604ebad60b29 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/60544 Reviewed-on: http://review.coreboot.org/4333 Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com> Tested-by: build bot (Jenkins) |

------------------------------------------------------------------------------- coreboot README ------------------------------------------------------------------------------- coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload. With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required. coreboot was formerly known as LinuxBIOS. Payloads -------- After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot. See http://www.coreboot.org/Payloads for a list of supported payloads. Supported Hardware ------------------ coreboot supports a wide range of chipsets, devices, and mainboards. For details please consult: * http://www.coreboot.org/Supported_Motherboards * http://www.coreboot.org/Supported_Chipsets_and_Devices Build Requirements ------------------ * gcc / g++ * make Optional: * doxygen (for generating/viewing documentation) * iasl (for targets with ACPI support) * gdb (for better debugging facilities on some targets) * ncurses (for 'make menuconfig') * flex and bison (for regenerating parsers) Building coreboot ----------------- Please consult http://www.coreboot.org/Build_HOWTO for details. Testing coreboot Without Modifying Your Hardware ------------------------------------------------ If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU. Please see http://www.coreboot.org/QEMU for details. Website and Mailing List ------------------------ Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website: http://www.coreboot.org You can contact us directly on the coreboot mailing list: http://www.coreboot.org/Mailinglist Copyright and License --------------------- The copyright on coreboot is owned by quite a large number of individual developers and companies.
