2012-03-30Make MTRR min hole alignment 64MBDuncan Laurie
This affects the algorithm when determining when to transform a range into a larger range with a hole. It is needed when for when I switch on an 8MB TSEG and cause the memory maps to go crazy. Also add header defines for the SMRR.

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.

2012-03-25Intel cpus: Fix deadlock on hyper-threading initKyösti Mälkki
Only the BSP CPU was able to start its hyper-threading CPU siblings. When an AP CPU attempts this it calls start_cpu() within start_cpu(), deadlocking the system with start_cpu_lock. At the time intel_sibling_init() is run, the BSP CPU is still walking the cpu_bus linked list in lapic_cpu_init: start_other_cpus(). A sibling CPU appended at the end of this list will get started. Also fail compile with #error if SERIAL_CPU_INIT==0, as microcode updates on hyper-threading sibling CPUs must be serialized. Tested with HT-enabled P4 Xeons on dual-socket604 platform.

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.

2011-10-15SMM: Move wbinvd after pmode jumpStefan Reinauer
According to Rudolf Marek putting a memory instruction between the CR0 write and the jmp in protected mode switching might hang the machine. Move it after the jmp. There might be a better solution for this, such as enabling the cache, as keeping it disabled does not prevent cache poisoning attacks, so there is no real point. However, Intel docs say that SMM code in ASEG is always running uncached, so we might want to consider running SMM out of TSEG instead, as well.

2011-10-11Fixed broken MTRR for >4GB memory on AMD K8 fam 0fh rev <=EOskar Enoksson
AMD K8 rev F and later implements a bit SYSCFG_MSR_TOM2WB to mark dram memory above 4GB as WB. However, AMD K8 rev E and earlier don't implement this bit and therefore need MTRR spanning dram memory above 4GB. The current implementation of amd_setup_mtrrs never generate MTRR above 4GB. This caused memory > 4GB not to be recognized in e.g. Linux on those rev E or older platforms. This commit should fix that bug.
