2012-07-30USBDEBUG: retry harder for slow devicesSven Schnelle
Some usb debug devices don't respond fast enough. The linux kernel (which uses almost the same usbdebug code) added a bit more retry code, so let's copy that. Even if it might look stupid, i pass the DBG_LOOPS argument through all functions to keep the code at least a bit in sync with the linux kernel code.

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.

Brevity is the soul of wit, except for error messages; then it's a sign of witlessness.

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.

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.

Add _PTS/_WAK methods to turn off/on the CPU/case fans and blink the power LED while sleeping. acpi_get_sleep_type() is in a seperate file i82371eb_wakeup.c because it is used in both romstage and ramstage after patch 3/3, whereas i82371eb_early_pm.c is used only in romstage. I used the name acpi_get_sleep_type instead of acpi_is_wakeup_early because I think acpi_is_wakeup_early is a bit misleading as a name since it doesn't return a boolean value. Other chipsets so far only ever set acpi_slp_type to 0 and 3, so the added check for acpi_slp_type == 2 (resume from S2) should not change behaviour of other boards: northbridge/intel/i945/northbridge.c:256:extern u8 acpi_slp_type; northbridge/intel/i945/northbridge.c:263: acpi_slp_type=0; northbridge/intel/i945/northbridge.c:267: acpi_slp_type=3; northbridge/intel/i945/northbridge.c:271: acpi_slp_type=0; southbridge/intel/i82801gx/i82801gx_lpc.c:171:extern u8 acpi_slp_type; southbridge/via/vt8237r/vt8237r_lpc.c:149:extern u8 acpi_slp_type; southbridge/via/vt8237r/vt8237r_lpc.c:238: acpi_slp_type = ((tmp & (7 << 10)) >> 10) == 1 ? 3 : 0 ; southbridge/via/vt8237r/vt8237r_lpc.c:239: printk(BIOS_DEBUG, "SLP_TYP type was %x %x\n", tmp, acpi_slp_type); Change-Id: I13feff0b8f49aa988e5467cdbef02981f0a6be8a Signed-off-by: Tobias Diedrich <ranma+coreboot@tdiedrich.de> Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/188 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
2011-09-07Add support for the tracing infastructure in coreboot.Rudolf Marek
The compiler is forced to emmit special functions on every entry/exit of the function. Add a compile time option to support it. Function entries will be printed in the console. The CONFIG_TRACE has more documentation. Patch for userspace tools will follow.

2011-08-04split CBFS support into shared core and extended functionsPatrick Georgi
The core is data structures and basic file finding capabilities, while option ROM handling, and loading stages and payloads is "extended". The core is rewritten to be BSD-l (its header already was), so can be copied to libpayload verbatim. It's also more robust in finding files in corrupted images, eg. after partial erase or update.

2011-07-12Do full flush on uart8250 only at end of printk.Kevin O'Connor
The previous code does a full flush of the uart after every character. Unfortunately, this can cause transmission delays on some serial ports. This patch changes the code so that it does a flush at the end of every printk instead of at the end of every character. This reduces the time it takes to transmit serial messages (up to 9% on my Asrock e350m1 board). It also makes the transmission time more consistent which is important when performing timing tests via serial transmissions.
