AMD: Reduce stack size from 64 KB to the default of 4 KB
Apply the following commit to all AMD boards.
commit 935850e08293cec1cb27d12358b27285e780566a Author: Stefan Reinauer reinauer@chromium.org Date: Mon May 6 16:16:03 2013 -0700
asrock/e350m1: reduce default stack size
The stack used on the ASRock E350M1 is significantly less than what we currently set (64k per core). In fact, we use about half of the default stack size (4k) on core 0 and even less on non BSP cores [1]:
$ grep stack coreboot_without_patch_but_monotonic_timer.log CPU1: stack_base 002a0000, stack_end 002afff8 CPU1: stack: 002a0000 - 002b0000, lowest used address 002afda8, stack used: 600 bytes CPU0: stack: 002b0000 - 002c0000, lowest used address 002bf75c, stack used: 2212 bytes
[…]
Reviewed-on: http://review.coreboot.org/3209
Please note that AGESA seems to define bigger stack sizes. But these seem to be too much too.
$ git grep STACK_SIZE src/vendorcode/amd […] src/vendorcode/amd/agesa/f14/Proc/CPU/Family/0x14/cpuF14CacheDefaults.c:#define BSP_STACK_SIZE 16384 src/vendorcode/amd/agesa/f14/Proc/CPU/Family/0x14/cpuF14CacheDefaults.c:#define CORE0_STACK_SIZE 16384 src/vendorcode/amd/agesa/f14/Proc/CPU/Family/0x14/cpuF14CacheDefaults.c:#define CORE1_STACK_SIZE 4096 src/vendorcode/amd/agesa/f14/Proc/CPU/Family/0x14/cpuF14CacheDefaults.c: BSP_STACK_SIZE, src/vendorcode/amd/agesa/f14/Proc/CPU/Family/0x14/cpuF14CacheDefaults.c: CORE0_STACK_SIZE, src/vendorcode/amd/agesa/f14/Proc/CPU/Family/0x14/cpuF14CacheDefaults.c: CORE1_STACK_SIZE, […]
The following command was used to create the patch.
$ git grep -l STACK_SIZE src/mainboard/ | xargs sed -i '/STACK_SIZE/,+3d'
