2015-04-14arm: Fix checkstack() to use correct stack sizeJulius Werner
checkstack() runs at the end of ramstage to warn about stack overflows, and it assumes that CONFIG_STACK_SIZE is always the size of the stack to check. This is only true for systems that bring up multiprocessing in ramstage and assign a separate stack for each core, like x86 and ARM64. Other architectures like ARM and MIPS (for now) don't touch secondary CPUs at all and currently don't look like they'll ever need to, so they generally stay on the same (SRAM-based) stack they have been on since their bootblock. This patch tries to model that difference by making these architectures explicitly set CONFIG_STACK_SIZE to zero, and using that as a cue to assume the whole (_estack - _stack) area in checkstack() instead. Also adds a BUG() to the stack overflow check, since that is currently just as non-fatal as the BIOS_ERR message (despite the incorrect "SYSTEM HALTED" output) but a little more easy to spot. Such a serious failure should not drown out in all the normal random pieces of lower case boot spam (also, I was intending to eventually have a look at assert() and BUG() to hopefully make them a little more useful/noticeable if I ever find the time for it). BRANCH=None BUG=None TEST=Booted Pinky, noticed it no longer complains about stack overflows. Built Falco, Ryu and Urara.

2012-11-13Clean up stack checking codeStefan Reinauer
Several small improvements of the stack checking code: - move the CPU0 stack check right before jumping to the payload and out of hardwaremain (that file is too crowded anyways) - fix prototype in lib.h - print size of used stack - use checkstack function both on CPU0 and CPU1-x - print amount of stack used per core Signed-off-by: Stefan Reinauer <reinauer@google.com> Test: Boot coreboot on Link, see the following output: ...

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.
