2012-11-08elog: add extended management engine eventDuncan Laurie
We are seeing ME disabled and ME error events on some devices and this extended info can help with debug. Also fix a potential issue where if the log does manage to get completely full it will never try to shrink it because the only call to shrink the log happens after a successful event write. Add a check at elog init time to shrink the log size.

2012-09-05buildsystem: Make CPU microcode updating more configurableAlexandru Gagniuc
This patch aims to improve the microcode in CBFS handling that was brought by the last patches from Stefan and the Chromium team. Choices in Kconfig - 1) Generate microcode from tree (default) - 2) Include external microcode file - 3) Do not put microcode in CBFS The idea is to give the user full control over including non-free blobs in the final ROM image. MICROCODE_INCLUDE_PATH Kconfig variable is eliminated. Microcode is handled by a special class, cpu_microcode, as such: cpu_microcode-y += microcode_file.c MICROCODE_IN_CBFS should, in the future, be eliminated. Right now it is needed by intel microcode updating. Once all intel cpus are converted to cbfs updating, this variable can go away. These files are then compiled and assembled into a binary CBFS file. The advantage of doing it this way versus the current method is that 1) The rule is CPU-agnostic 2) Gives user more control over if and how to include microcode blobs 3) The rules for building the microcode binary are kept in src/cpu/Makefile.inc, and thus would not clobber the other makefiles, which are already overloaded and very difficult to navigate.

This change defines a weak symbol (mainboard_post) that can be overridden by a real mainboard_post function. If, for example, you'd like to do something fancy before the payload starts, you can add this to mainboard.c: void mainboard_post(u8 value) { switch(value){ case POST_TIME_TO_PARTY: some_fancy_lights(); break; } } Maybe the post function should be an entry in the device.

2012-08-04Make the device tree available in the rom stageStefan Reinauer
We thought about two ways to do this change. The way we decided to try was to 1. drop all ops from devices in romstage 2. constify all devices in romstage (make them read-only) so we can compile static.c into romstage 3. the device tree "devices" can be used to read configuration from the device tree (and nothing else, really) 4. the device tree devices are accessed through struct device * in romstage only. device_t stays the typedef to int in romstage 5. Use the same static.c file in ramstage and romstage We declare structs as follows: ROMSTAGE_CONST struct bus dev_root_links[]; ROMSTAGE_CONST is const in romstage and empty in ramstage; This forces all of the device tree into the text area. So a struct looks like this: static ROMSTAGE_CONST struct device _dev21 = { #ifndef __PRE_RAM__ .ops = 0, #endif .bus = &_dev7_links[0], .path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}}, .enabled = 0, .on_mainboard = 1, .subsystem_vendor = 0x1ae0, .subsystem_device = 0xc000, .link_list = NULL, .sibling = &_dev22, #ifndef __PRE_RAM__ .chip_ops = &southbridge_intel_bd82x6x_ops, #endif .chip_info = &southbridge_intel_bd82x6x_info_10, .next=&_dev22 }; Change-Id: I722454d8d3c40baf7df989f5a6891f6ba7db5727 Signed-off-by: Ronald G.

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.

2012-07-24SMM: 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.

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.

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.

Traditionally coreboot's SMM handler runs in ASEG (0xa0000), "behind" the graphics memory. This approach has two issues: - It limits the possible size of the SMM handler (and the number of CPUs supported in a system) - It's not considered a supported path anymore in newer CPUs.

2012-04-03Add support for Intel Turbo Boost featureStefan Reinauer
From wikipedia: Intel Turbo Boost is a technology implemented by Intel in certain versions of their Nehalem- and Sandy Bridge-based CPUs, including Core i5 and Core i7 that enables the processor to run above its base operating frequency via dynamic control of the CPU's "clock rate". It is activated when the operating system requests the highest performance state of the processor.

2012-03-29Add infrastructure for global data in the CAR phase of bootGabe Black
The cbmem console structure and car global data are put in their own section, with the cbmem console coming after the global data. These areas are linked to be where CAR is available and at the very bottom of the stack. There is one shortcoming of this change: The section created by this change needs to be stripped out by the Makefile since leaving it in confuses cbfstool when it installs the stage in the image. I would like to make the tools link those symbols at the right location but leave allocation of that space out of the ELF.

2012-03-29CBMEM CONSOLE: Add CBMEM console driver implementation.Vadim Bendebury
The CBMEM console driver saves console output in a CBMEM area, which then is made available to Linux applications for perusing. There are some system limitations which need to be worked around to achieve this goal: - some console traffic is generated before DRAM is initialized, leave alone CBMEM initialized. - after the RAM based stage starts, a lot of traffic is generated before CBMEM is initialized. As a result, the console log lives in three different places - the bottom of the cache as RAM space, the CBMEM buffer (where it is expected to be) and a static buffer used early in the RAM stage. When execution starts (in the cache as RAM mode), the console buffer is allocated at the bottom of the cache as RAM memory address range. Once DRAM is initialized, the CBMEM structure is initialized, and then the console buffer contents are copied from the bottom of the cache as RAM space into the CBMEM area right before the cache as RAM mode is disabled. The src/lib/cbmem_console.c:cbmemc_reinit() takes care of the copying. At this point the cache as RAM memory is about to be disabled, but the ROM stage is still going generating console output. To make sure this output is not lost, cbmemc_reinit() saves the new buffer address at a fixed location (0x600 was chosen for this), and the actual "printing" function checks to see if the RAM is already initialized (the stack is in RAM), and if so, gets the console buffer pointer from this location instead of using the cache as RAM address. When the RAM stage starts, a static buffer is used to store the console output, as the CBMEM buffer location is not known. Then, when CBMEM is reinitialized, cbmemc_reinit() again takes care of the copying. In case the allocated buffers are not large enough, the excessive data is dropped, and the copying routine adds some text to the output buffer to indicate that there has been data lost and how many characters were dropped.

This patch adds code to initialize the time stamp collection facility in coreboot. It adds a table in the CBMEM section, which provides the base timer reading value (all other readings are offsets of this one) and an array of timestamp id/timestamp value pairs. Just two values are being added now, this will have to be used more extensively and also integrated into payloads to provide more comprehensive boot process time measurements. Also, since the CBMEM area could already contain a section (from the previous run, before reset), when processing a section addition request we should check if a section already exists and return its address, if so.

2012-03-28Initialize CBMEM early.Vadim Bendebury
We want to be able to share data between different phases of firmware (rom stage/ram stage/payload). Coreboot CBMEM seems an appropriate location for this data, but normally it is not initialized until coreboot reaches the ram stage. This change initializes the CBMEM while still in rom stage in case CONFIG_EARLY_CBMEM_INIT is set. Note that there is a discrepancy in how coreboot determines the size of DRAM at rom and ram stages, get_top_of_ram() is used at rom stage and is not defined for all platforms. Those platforms will have to define this function should they enable the CONFIG_EARLY_CBMEM_INIT flag.
