2012-07-26ELOG: Add support for SMM and kernel GSMI driverDuncan Laurie
The linux kernel contains an SMI driver that was written by me (Duncan) and upstreamed a couple years ago called GSMI. This driver will format a parameter buffer and pass pointers to this parameter buffer to the SMI handler. It uses this to generate events for kernel shutdown reasons: Clean, Panic, Oops, etc. This function expects to be passed pointers into the SMM state save area that correspond to the prameter buffer and the return code, which are typically EAX and EBX. The format of the parameter buffer is defined in the kernel driver so we implement the same interface here in order to be compatible. GSMI_CMD_HANDSHAKE: this is an early call that it does to try and detect what kind of BIOS is running. GSMI_CMD_SET_EVENT_LOG: this contains a parameter buffer that has event type and data. The kernel-specific events are translated here and raw events are passed through as well which allows any run-time event to be added for testing. GSMI_CMD_CLEAR_EVENT_LOG: this command clears the event log. First the gsmi driver must be enabled in the kernel with CONFIG_GOOGLE_GSMI and then events can be added via sysfs and events are automatically generated for various kernel shutdown reasons. These can be seen in the event log as the 'Kernel Event' type: 169 | 2012-06-23 15:03:04 | Kernl Event | Clean Shutdown 181 | 2012-06-23 16:26:32 | Kernl Event | Oops 181 | 2012-06-23 16:26:32 | Kernl Event | Panic Change-Id: Ic0a3916401f0d9811e4aa8b2c560657dccc920c1 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1316 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-07-25chromeos: Pass pointer to ChromeOS ACPI structure instead of VB Shared DataStefan Reinauer
coreboot used to pass some information to u-boot in the coreboot table and other information in a modified flat device tree. Since the FDT code was never upstreamed and removed from our tree, u-boot was changed to get the information it needs from the coreboot table alone. However, in the process of this change only the vboot shared data structure was passed on by coreboot, so when u-boot tried to update the ChromeOS specific ACPI entries, it would accidently overwrite the vboot data. This patch passes on the ChromeOS specific ACPI data structure instead of the vboot shared data. Another change to u-boot will teach it how to get to the vboot shared data from there.

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.

2012-07-24ELOG: Add support for flash based event logDuncan Laurie
This is based around the SMBIOS event log specification but expanded with OEM event types to support more specific and relevant system events. It requires flash storage and a minimum 4K block (or flash block size) that should be allocated in the FMAP. A copy of the event log is maintained in memory for convenience and speed and the in-memory copy is written to flash at specific points. The log is automatically shunk when it reaches a configurable full threshold in order to not get stuck with a full log that needs OS help to clear. ELOG implements the specification published here: http://code.google.com/p/firmware-event-log/wiki/FirmwareEventLogDesign And is similar to what we use in other firmware at Google. This implementation does not support double-buffered flash regions. This is done because speed is valued over the log reliability and it keeps the code simpler for the first version. This is a large commit and by itself it just provides a new driver that is made available to coreboot. Without additional patches it is not very useful, but the end result is an event log that will contain entries like this: 171 | 2012-06-23 16:02:55 | System boot | 285 172 | 2012-06-23 16:02:55 | EC Event | Power Button 173 | 2012-06-23 16:02:55 | SUS Power Fail 174 | 2012-06-23 16:02:55 | System Reset 175 | 2012-06-23 16:02:55 | ACPI Wake | S5 Change-Id: I985524c67f525c8a268eccbd856c1a4c2a426889 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1311 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

Ivybridge B0+ CPUs are capable of supporting multiple TDP levels. This complicates the default case because now the registers that were reporting max non-turbo ratio are reporting that value for the highest possible TDP level. For now this change just forces everything to use the Nominal TDP values instead of the higher (or lower) levels. - When building P-state tables, determine the P[1] (max non turbo) ratio based on the Nominal ratio if available. - Set the turbo activation ratio to the Nominal max ratio. - Mirror the power level settings in new MCHBAR register after they are written, which happens after BIOS_RESET_CPL is set. - Set the current ratio to Nominal ratio at boot. 1) Verify that P-state table is generated properly with P[0]=1801MHz (ratio 0x1C) and P[1]=1800MHz (ratio 0x12) PSS: 1801MHz power 17000 control 0x1c00 status 0x1c00 PSS: 1800MHz power 17000 control 0x1200 status 0x1200 2) Verify power limits in MCHBAR match PKG_POWER_LIMIT: > rdmsr 0 0x610 0x800080aa00dc8088 > mmio_read32 0xfed159a4 0x000080aa > mmio_read32 0xfed159a0 0x00dc8088 3) Verify turbo activation ratio is set to nominal ratio: > rdmsr 0 0x64c 0x0000000000000012 4) Check that proper ratio was set at boot on one core only: > grep 'frequency set to' /sys/firmware/log model_x06ax: frequency set to 1800 model_x06ax: frequency set to 1800 model_x06ax: frequency set to 1800 model_x06ax: frequency set to 1800 Change-Id: I592e60a7740f31b140986a8269dca91b4adbb270 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1304 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-07-24Implement stack overflow checking for the BSPRonald G. Minnich
Previous patches implemented stack overflow checking for the APs. This patch builds on the BSP stack poisoning patch to implement stack overflow checking for the BSP, and also prints out maximum stack usage. It reveals that our 32K stack is ridiculously oversized, especially now that the lzma decoder doesn't use a giant 16K on-stack array. Break the stack checking out into a separate function, which we will later use for the APs. CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8 To test failure, change the DEADBEEF stack poison value in c_start.S to something else. Then we should get an error like this: Stack overrun on BSP.Increase stack from current 32768 bytes CPU0: stack from 00180000 to 00188000:Lowest stack address 00180000 Separate the act of loading from the act of starting the payload. This allows us better error management and reporting of stack use. Now we see: CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8 Tested for both success and failure on Link. At the same time, feel free to carefully check my manipulation of _estack. Change-Id: Ibb09738b15ec6a5510ac81e45dd82756bfa5aac2 Signed-off-by: Ronald G.

In the short term there might be devices with Sandy Bridge CPUs on mainboards with Panther Point PCHes. While this configuration option is perfectly valid, coreboot currently ties Sandy Bridge to Cougar Point and Ivy Bridge to Panther Point. One occurence is in the ME handling code. To make coreboot most flexible, compile both ME handlers into coreboot and decide at runtime which one to use.

2012-07-24Add microcode blob processingVadim Bendebury
When microcode storage in CBFS is enabled, the make system is supposed to generate the microcode blob and place it into the generated ROM image as a CBFS component. The microcode source representation does not change: it is still an array of 32 bit constants. This new addition compiles the array into a separate object file and then strips all sections but data. The raw data section is then included into CBFS as a file named 'microcode_blob.bin' of type 0x53, which is assigned to microcode storage.
