2012-07-24SMM: Add heap region and move C handler higher in regionDuncan Laurie
In order to support SPI and ELOG drivers the SMM region needs to be able to be larger than the previous allocation below 0x7400. Now that we have support for 4M TSEG we do not need to live in this region. This change adds a 16KB heap region abofe the save state area at TSEG+64KB and moves the C handler above this. The heap region is then available for malloc and the C handler can grow to support flash and event log features. While updating the memory map comment in assembly stub I also added a pause instruction to the cpu spin lock as this was added to the C code in latest upstream rebase. Dump sympbols from smm.elf binary to see the new regions: 00010000 B _heap 00014000 B _eheap 00014000 T _smm_c_handler_start 0001b240 T _smm_c_handler_end Change-Id: I45f0ab4df1fdef3b626f877094a58587476ac634 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1308 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-07-24CPU: Add basic support for Nominal Configurable TDPDuncan Laurie
Ivybridge B0+ CPUs are capable of supporting multiple TDP levels. This complicates the default case because now the registers that were reporting max non-turbo ratio are reporting that value for the highest possible TDP level. For now this change just forces everything to use the Nominal TDP values instead of the higher (or lower) levels. - When building P-state tables, determine the P[1] (max non turbo) ratio based on the Nominal ratio if available. - Set the turbo activation ratio to the Nominal max ratio. - Mirror the power level settings in new MCHBAR register after they are written, which happens after BIOS_RESET_CPL is set. - Set the current ratio to Nominal ratio at boot. 1) Verify that P-state table is generated properly with P[0]=1801MHz (ratio 0x1C) and P[1]=1800MHz (ratio 0x12) PSS: 1801MHz power 17000 control 0x1c00 status 0x1c00 PSS: 1800MHz power 17000 control 0x1200 status 0x1200 2) Verify power limits in MCHBAR match PKG_POWER_LIMIT: > rdmsr 0 0x610 0x800080aa00dc8088 > mmio_read32 0xfed159a4 0x000080aa > mmio_read32 0xfed159a0 0x00dc8088 3) Verify turbo activation ratio is set to nominal ratio: > rdmsr 0 0x64c 0x0000000000000012 4) Check that proper ratio was set at boot on one core only: > grep 'frequency set to' /sys/firmware/log model_x06ax: frequency set to 1800 model_x06ax: frequency set to 1800 model_x06ax: frequency set to 1800 model_x06ax: frequency set to 1800 Change-Id: I592e60a7740f31b140986a8269dca91b4adbb270 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1304 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.

2012-07-24Remove code that enables/disables VMX in coreboot on chromebooks.Ronald G. Minnich
There are several reasons for this: 1. It's a core setting, not a platform setting, which is bizarre. But, we disable vmx via an SMI, and that only happens on core 0. Hence, the code did not correctly make the same settings on all cores- one had them disabled, the others were in an unknown state. When (e.g.) kvm started on a vmx-enabled core, then moved to a vmx-disabled core, the processor would reset *very* quickly. Changing this would be messy. 2. On the CPU on link, there is something about trying to set the lock bit that is getting a GPF. 3. It's the wrong place and time to set it. Once controlled, they can't be changed in the kernel. The kernel is what should control this feature, not the BIOS, as we have learned time and time again. If somebody is in as root and can start a VM, you have a lot more to worry about than someone starting a guest virtual machine.

This check got in the code when some Linux distros shipped broken linkers around 1999. Since then, the code around that check was changed, and it does not make sense anymore to have this check.

2012-07-24Make memalign print useful messages on failureRonald G. Minnich
Brevity is the soul of wit, except for error messages; then it's a sign of witlessness. I can say this because this error message may be my fault, although it is lost in the 20th century code base so who knows. Anyway, when memalign dies, it's not a bad idea to have a lot of information about what went wrong. So instead of the terse single bit of "something failed" this patch changes things to be a bit more useful. Change-Id: I8851502297e0ae9773912839ebfdf4f9574c8087 Signed-off-by: Ronald G.

2012-07-24Fixes to enable RC6 on IvyBridgeDuncan Laurie
- The unneeded poll on non-MT force-wake bit was timing out and causing the gma_pm_init_pre_vbios() function to exit early so it was not preparing PM registers properly. I changed the gtt_poll() calls to not return on timeout unless it can't proceed so we don't see half-initialized registers. - RC6+ (Deep Render Standby) is not working reliably so we can just enable RC6 in the BIOS and let the kernel decide if it wants to enable RC6+ later. This Kernel message is new in kernel 3.4: [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off Change-Id: I69d005ba56be8c7684a4ea1133a1d761f7c07acc Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1268 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
