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)

2012-08-04Add a capability for mainboard-specific posting.Alexandru Gagniuc
Some mainboards have really nice capabilities for posting, beyond simple POST cards. Further, some can not use a POST card. This change defines a weak symbol (mainboard_post) that can be overridden by a real mainboard_post function. If, for example, you'd like to do something fancy before the payload starts, you can add this to mainboard.c: void mainboard_post(u8 value) { switch(value){ case POST_TIME_TO_PARTY: some_fancy_lights(); break; } } Maybe the post function should be an entry in the device. We're beginning to over-use weak symbols. BUG=None TEST=Build and boot a google chromebook. Observe that it still works. Use it to drive some pretty lights.

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.

Before (data flag ignored -> broken): 66 DATA: e944f1 JMP 1ff6 After (fixed): 66 DATA: e944f1ffff JMP 00001ff8 This subtle difference in the length of decoded instruction meant that the VBE call jumped to the routine setting AX=0x14F (VBE Failed) instead of the routine that set AX=0x4F (VBE success). The ability to run the same code in vm86 significantly aided the debugging of this issue.

2012-08-01AMD F15tn northbridge: Remove the misleading 0x100 from the limitk.zbao
I dont known if missed something, but why an extra 0x100 was added to limit? My board would get the wrong memory table entry 7f000000-7fffffff as RAM, which is higher than TOM. coreboot memory table: 0. 0000000000000000-0000000000000fff: CONFIGURATION TABLES 1. 0000000000001000-000000000009ffff: RAM 2. 00000000000c0000-000000005e13efff: RAM 3. 000000005e13f000-000000005effffff: CONFIGURATION TABLES 4. 000000005f000000-000000007effffff: RESERVED 5. 000000007f000000-000000007fffffff: RAM 6. 00000000a0000000-00000000afffffff: RESERVED Ronald G. Minnich: I think someone who wrote the code was trying to round up the next 0x100 boundary and did it incorrectly. Here is code that would do it correctly: limitk = ((resource_t)((d.mask + 0x00000ff) & 0x1fffff00)) << 9 ; Zheng: Plus 0xFF is correct, but the d.mask take bit 0 as enable it. This bit should be clear when we try to calculate the limitk.

2012-08-01Intel Sandybridge and UMA: use mmio_resource()Kyösti Mälkki
With SandyBridge northbridge code, uma_memory_size was reset to zero before variable MTRRs were set. This means MTRR setup routine did not previously create a un-cacheable hole for uma. 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.

2012-07-30USBDEBUG: retry harder for slow devicesSven Schnelle
Some usb debug devices don't respond fast enough. The linux kernel (which uses almost the same usbdebug code) added a bit more retry code, so let's copy that. Even if it might look stupid, i pass the DBG_LOOPS argument through all functions to keep the code at least a bit in sync with the linux kernel code.

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().
