2012-08-09Synchronize rdtsc instructionsStefan Reinauer
The CPU can arbitrarily reorder calls to rdtsc, significantly reducing the precision of timing using the CPUs time stamp counter. Unfortunately the method of synchronizing rdtsc is different on AMD and Intel CPUs. There is a generic method, using the cpuid instruction, but that uses up a lot of registers, and is very slow. Hence, use the correct lfence/mfence instructions (for CPUs that we know support it) Change-Id: I17ecb48d283f38f23148c13159aceda704c64ea5 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/1422 Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com> Tested-by: build bot (Jenkins)

2012-08-04Make the device tree available in the rom stageStefan Reinauer
We thought about two ways to do this change. The way we decided to try was to 1. drop all ops from devices in romstage 2. constify all devices in romstage (make them read-only) so we can compile static.c into romstage 3. the device tree "devices" can be used to read configuration from the device tree (and nothing else, really) 4. the device tree devices are accessed through struct device * in romstage only. device_t stays the typedef to int in romstage 5. Use the same static.c file in ramstage and romstage We declare structs as follows: ROMSTAGE_CONST struct bus dev_root_links[]; ROMSTAGE_CONST is const in romstage and empty in ramstage; This forces all of the device tree into the text area. So a struct looks like this: static ROMSTAGE_CONST struct device _dev21 = { #ifndef __PRE_RAM__ .ops = 0, #endif .bus = &_dev7_links[0], .path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}}, .enabled = 0, .on_mainboard = 1, .subsystem_vendor = 0x1ae0, .subsystem_device = 0xc000, .link_list = NULL, .sibling = &_dev22, #ifndef __PRE_RAM__ .chip_ops = &southbridge_intel_bd82x6x_ops, #endif .chip_info = &southbridge_intel_bd82x6x_info_10, .next=&_dev22 }; Change-Id: I722454d8d3c40baf7df989f5a6891f6ba7db5727 Signed-off-by: Ronald G.
