2012-11-08spi: fix erase in SMM while SPIBAR is lockedDuncan Laurie
The handling of write enable was not entirely correct, the opcode needs to be skipped when the controller is locked down. Addresses were not getting set properly for erase commands which seemed to mostly work when the previous command had set an address. Tested by adding events to the event log at runtime on a freslhy flashed device (with locked down SPI controller) until the log log shrink happens to ensure it does not hang: hexdump -C elog.event.kernel_clean 00000000 01 00 00 00 ad de 00 00 00 00 for x in $(seq 1 232); do cat elog.event.kernel_clean > /sys/firmware/gsmi/append_to_eventlog done mosys eventlog list | tail -6 154 | 2012-09-01 13:54:43 | Kernel Event | Clean Shutdown 155 | 2012-09-01 13:54:43 | Kernel Event | Clean Shutdown 156 | 2012-09-01 13:54:43 | Kernel Event | Clean Shutdown 157 | 2012-09-01 13:54:43 | Kernel Event | Clean Shutdown 158 | 2012-09-01 13:54:43 | Log area cleared | 1030 159 | 2012-09-01 13:54:43 | Kernel Event | Clean Shutdown Change-Id: I3a50dae54422a9ff37daefce3632f8bcbe4eb89f Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1717 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

Generate ACPI sleep state events and power button events and verify they show up in the log: 153 | 2012-06-23 17:12:59 | ACPI Enter | S5 184 | 2012-06-23 17:15:50 | ACPI Enter | S3 216 | 2012-06-23 17:28:58 | Power Button Change-Id: Iba134d619780e459bce189d36d57844997ffb009 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1320 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-07-26ELOG: Support GSMI in CPT/PPT southbridge SMI handlerDuncan Laurie
In order to support the GSMI interface the SMI handler needs to find and use the state save area from the same CPU that initiated the SMI. In this case it is a synchronous SMI resulting form an IO write to port 0xB2. To find the right CPU state save area iterate over the region until the "IO Misc Info" field reports the expected value and then proceed to use that state save area. This is needed because the coreboot SMI handler only executes on one core, and that core is non-deterministic. It is likely that the core executing the C SMM handler is not the same one that actually did the IO write to 0xB2 and generated the SMI. The GSMI parameter buffer is passed as a pointer to EBX in the tate save area, and the GSMI command is extracted from EAX before it is used as the return value. This interface is tested by enabling CONFIG_GOOGLE_GSMI in the kernel and generating events and verifying that they end up in the event log. 159 | 2012-06-23 16:22:45 | Kernl Event | Clean Shutdown 184 | 2012-06-23 17:14:05 | Kernl Event | Oops 185 | 2012-06-23 17:14:05 | Kernl Event | Panic Change-Id: Ic121ea69e9f50c88467c435e095c3e3629989806 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1317 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

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.

2012-07-24SMM: Fix state save map for sandybridge and TSEGDuncan Laurie
There are enough differences that it is worth defining the proper map for the sandybridge/ivybridge CPUs. The state save map was not being addressed properly for TSEG and needs to use the right offset instead of pointing in ASEG. To do this properly add a required southbridge export to return the TSEG base and use that where appropriate.
