There are two errors in the code. The first one is a missing $ sign in mov _stack, %esp. Thanks to Ronald G Minnich for catching that bug. The second bug is the 'incl %eax', which shouldn't be there, as there's no secondary CPU with index 0. CPU0 uses always the stack below _estack.

Traditionally coreboot's SMM handler runs in ASEG (0xa0000), "behind" the graphics memory. This approach has two issues: - It limits the possible size of the SMM handler (and the number of CPUs supported in a system) - It's not considered a supported path anymore in newer CPUs.

From wikipedia: Intel Turbo Boost is a technology implemented by Intel in certain versions of their Nehalem- and Sandy Bridge-based CPUs, including Core i5 and Core i7 that enables the processor to run above its base operating frequency via dynamic control of the CPU's "clock rate". It is activated when the operating system requests the highest performance state of the processor.

The socket mPGA604 is for P4 Xeon which to my knowledge is always HT-enabled. I assume the existing usage of car/cache_as_ram.inc on socket_mPGA604, namely the Tyan S2735, as broken. Existing car/cache_as_ram.inc has invalid SIPI vector and it does not initialise AP CPU's to activate L2 cache. Other mPGA604 boards are not affected, as they have not been converted to CAR.

2012-03-31Add support for RAM-less multi-processor initKyösti Mälkki
For a hyper-threading processor, enabling cache requires that both the BSP and AP CPU clear CR0.CD (Cache Disable) bit. For a Cache-As-Ram implementation, partial multi-processor initialisation precedes raminit and AP CPUs' 16bit entry must be run from ROM. The AP CPU can only start execute real-mode code at a 4kB aligned address below 1MB. The protected mode entry code for AP is identical with the BSP code, which is already located at the top of bootblock. This patch takes the simplest approach and aligns the bootblock 16 bit entry at highest possible 4kB boundary below 1MB. The symbol ap_sipi_vector is tested to match CONFIG_AP_SIPI_VECTOR used by the CAR code in romstage. Adress is not expected to ever change, but if it does, link will fail.

2012-03-30MTRR: add alternate allocation method for odd memory mapsDuncan Laurie
With >= 4GB memory installed we get a memory map split in the middle due to remap that has boundaries that are inconveniently aligned for MTRRs due to the various UMA regions. 0000MB-2780MB 2780MB RAM (writeback) 2780MB-2782MB 2MB TSEG (uncached/SMRR) 2782MB-2784MB 2MB GFX GTT (uncached) 2784MB-2816MB 32MB GFX UMA (uncached) 2816MB-4096MB 1280MB EMPTY (N/A) 4096MB-5368MB 1272MB RAM (writeback) 5368MB-5376MB 8MB ME UMA (uncached) The default MTRR allocation method of trying to cover everything with one MTRR and then carve out a single uncached region does not work for the GPU aperture which needs write-combining type, and it also has issues trying to cover the uneven boundaries in the avaiable variable MTRRs. My goal was to make a minimal set of changes and avoid modifying behavior on existing systems with an algorithm that is not always optimal for a typical memory layout. So the flag 'above4gb=2' will change these allocation behaviors: 1) Detect the number of available variable MTRRs rather than limiting to hardcoded value. We need every last MTRR. 2) Don't try to cover all RAM with one MTRR, instead let each RAM region get covered independently. 3) Don't assume uma_memory_base is part of the last region and increase the size of that region. In this case the UMA region is carved out from the lower memory region and it is already declared as part of the ram region. 4) If a memory region can't be covered with MTRRs >= 16MB then instead make a larger region and trim it with uncached MTRRs.

This isn't always the right value: I.e. on model_6[ef]x Core (2) Duo CPUs physical address size is 36, while Xeons from the same family have 38 bits, which results in invalid MTRR setup. Fix this by getting the right number from CPUID.

2011-12-05Bootblock does not need a unique boot_cpu()Kyösti Mälkki
Detection of a CPU being a BSP CPU is not dependent of the existence of northbridge and/or southbridge init code in the bootblock. Even if CONFIG_LOGICAL_CPUS==0, boot_cpu() can get executed on an AP CPU of a hyper-threading CPU and needs to return actual BSP bit from MSR.

It is meant to be a address and not a dereference. Otherwise MTRR is filled with code and not with the address. This is what I hate at most on the AT&T syntax. Instead of taking the address, it was a dereference. Not greatly visible, except I wondered why opcode is not 0xb4 but 0xa1 and it took another half an our to see it.

2011-10-17Fixes several issues with amd k8 SSDT P-state generationOskar Enoksson
First issue fixed: For multi-socket CPU the current implementation emitted Processor objects for cores in the first CPU only. This commit fixes the bug by really emitting one Processor object for each core. However, the unlikely case of mixed CPU models is still not handled correctly. Second issue fixed: One loop was wrong in case a processor in the table declares no P-states at all. The rewritten loop is safe. Some possibly dangerous array lengths were also fixed. Third issue: on MP-boards the recommended ramp-voltage (RVO) is 0mV according to the BKDG. The current implementation always set it to 25mV. This commit selects 0 or 25mV depending on CONFIG_MAX_PHYSICAL_CPUS. Fourth issue: If a processor without PowerNow! support was inserted in a system with coreboot configured with SET_FIDVID then the boot process hanged mysteriously and very early. Apparently because init_fidvid_ap tampers with non-existing registers. This commit fixes the bug by bailing out from init_fidvid_ap if PowerNow! capability is missing.
