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.

3 (with one of them way too much assembler code). On the way, I had to make some changes to the way the code is built, which is an effort I want to expand over time. Right now, large portions of the in-ROM part of coreboot is compiled as a single file, with lots of .c files including other .c files. That has its justification for pre-raminit code, but it also affects lots of post-raminit code (memcpy doesn't really make sense before raminit, or at least CAR) The coreboot_apc code (AMD boards) gained some .c includes because I don't know that part of the code enough to really rework it and only have limited possibilities to test it. The includes should give an identical situation for this part of the code. This change was posted as set of 6 patches to the list, but they were mostly split for review purposes, hence commit them all at once. They can still be backed up using the patch files, if necessary.

2009-04-25Move decompression further down the code flow, so that - wherePatrick Georgi
possible - code is decompressed directly to the right place (instead of copying around, as before). The downside of this approach is that it's not possible (without API changes to the decompressors) to put partial segments into bounce buffers. So if a segment collides with coreboot _and_ is compressed, it's bounced entirely. But, as this only brings back the copy we already had before, the new worst case is better than the average before. It also fixes handling of compressed segments. Signed-off-by: Patrick Georgi <patrick.georgi@coresystems.de> Acked-by: Ronald G.
