Factor CPU allocation out of AMD northbridge codes. As CPU topology information is required for generation of certain ACPI tables, make this code globally available. For AMDK8 and AMDFAM10 northbridge, there is a possible case of BSP CPU with lapicid!=0. We do not want to leave the lapic 0 from devicetree unused, so always use that node for BSP CPU.

Keep the behaviour that way, mmio_resource() has a prerequisuite that the new region does not overlap with any cacheable ram_resource(). The result is not optimal setup in the number of used MTRRs, but continue with this approach until MTRR algorithm is improved.

2012-07-27Intel and GFXUMA: fix MTRR and use uma_resource()Kyösti Mälkki
Commit 2d42b340034ff005693482ef9ca34ce3e0f08371 changed the variable MTRR setup and removed compensation of uma_memory_size in the cacheable memory resources. Since the cacheable region size was no longer divisible by a large power of 2, like 256 MB, this caused excessive use of MTRRs. As first symptoms, slow boot with grub and poor user response. As a solution, register the actual top of low ram with ram_resource(), and do not subtract the UMA/TSEG regions from it. TSEG may require further work as the original did not appear exactly right to begin with. To have UMA as un-cacheable, use uma_resource().

This will set the CPU back to nominal configuration by sequencing the required changes in the correct (reverse) order. This does not introduce any functional changes and must be paired with additional changes to be useful.

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.

2012-07-24Make ACPI code detect Sandy/Ivy Bridge dynamicallyStefan Reinauer
On systems with socketed CPUs we want to be able to drop in a Sandy Bridge or Ivy Bridge CPU without recompiling the firmware. Hence, detect the north bridge dynamically. In order for this to work, we need Ivy Bridge MRC and coreboot configured for Ivy Bridge.

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.
