2014-04-16cpu/amd/agesa/family15tn: Add udelay implementation for SMMAlexandru Gagniuc
This is a small implementation which uses only MSRs and rdtsc, without relying on northbridge or other system hardware. It's SMM safe in that it only reads registers, and doesn't modify the state of the hardware.

2014-04-16cpu/amd/agesa/family15tn: Add initial support for SMM modeAlexandru Gagniuc
This is the minimal setup needed to be able to execute SMI handlers. Only support for ASEG handlers is added, which should be sufficient for Trinity (up to 4 cores). There are a few hacks which need to be introduced in generic code in order to make this work properly, but these hacks are self-contained. They are a not a result of any special needs of this CPU, but rather from a poorly designed infrastructure. Comments are added to explain how such code could be refactored in the future.

2014-04-15vendorcode/amd/agesa/fam15tn: Build as a static libraryAlexandru Gagniuc
Up until now, we were building AGESA by specifying each AGESA source file and adding it to the list of romstage and ramstage source files. As a result, we were compiling each AGESA source twice, despite the fact that it does not depend on the stage we're in. Since AGESA is stage-independent, we can build it just once, and use the resulting static library in both rom and ram stages. We still keep the practice of specifying every single AGESA directory as an include dir and adding the AGESA CFLAGS to our global CFLAGS; this is needed due to the way AGESA builds.

Split the Parmer, Family 15tn, and Hudson DSDT into groups. This splits the DSDT table into includable ASL files which carry details specific to the Family 15tn APU, the Parmer platform, and the Hudson FCH. The dsdt.asl file in the mainboard directory contains only #include references to the appropriate files. Initially, this split was done by moving each piece of functionality into its own file (e.g. IRQ routing and mapping, processor tree, sleep states and sleep methods, etc.) and those pieces were #included in dsdt.asl to ensure an exact match (via acpidump/acpixtract/iasl -d) with the extant version of the table. Once the new tables were found to exactly match the existing tables, the pieces were rearranged into reasonable groups (e.g. fch.asl, northbridge.asl, pci_int.asl, etc.). Some include files have no content but are left as a template for other platforms and as placeholders for completing the ACPI implementation for Parmer (e.g. thermal.asl, superio.asl, ide.asl, sata.asl, etc.).

2013-04-11Persimmon/Fam14/SB800 DSDT: Split into common areasMike Loptien
Split the Persimmon DSDT into common code areas. For example, split the Southbridge specific code into the Southbridge directory and CPU specific code into the CPU directory. Also adding the superio.asl file to the Persimmon DSDT tree. This file is empty for the moment but will be necessary in the future. I have also emptied the thermal.asl file in the mainboard directory because it does not seem to perform as intended (fan control does not change when it is brought back into the code base) and it has been inside a '#if 0' statement for a long time. Removing it until it is decided that it is actually necessary. This change was verified in three different ways: 1. Visual comparison of the compiled DSDT pulled from the Persimmon after booting into Linux using the ACPI tools acpidump, acpixtract, and iasl. The comparison was done between the DSDT before and after doing the split work. This test is somewhat difficult considering the expanse of the changes. Blocks of code have been moved, and others changed. 2. Linux logs were dumped before and after the DSDT split. Logs dumped and compared include dmesg and lspci -tv. Neither log changed significantly between the two compare points. 3. The test suite FWTS was run on the Coreboot build both before and after doing the DSDT split with the command 'sudo fwts -b -P -u'. The flag -b specifies all batch jobs, -P specifies all power tests, and -u specifies utilities. Interactive jobs were not run as most of them consist of laptop checks. Again, there were no significant changes between the two endpoints. These tests lead me to believe that there was no change in the functionality of the ACPI tables apart from what is known and expected. This patch is the first of a series of patches to split the DSDT. The ASRock patch was merged before this one and breaks the ASROCK E350M1 build (patch 8d80a3fb: http://review.coreboot.org/#/c/3050/). Please be aware of this dependency when pulling these patches. Other patches that depend on this patch are 'AMD Fam14: Split out the AMD Fam14 DSDT' (http://review.coreboot.org/#/c/3051/) and 'Fam14 DSDT: Also return for unrecognized UUID in _OSC' (http://review.coreboot.org/#/c/3052/) Change-Id: I53ff59909cceb30a08e8eab3d59b30b97c802726 Signed-off-by: Mike Loptien <mike.loptien@se-eng.com> Reviewed-on: http://review.coreboot.org/3048 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martin.roth@se-eng.com>

2013-03-22x86: unify amd and non-amd MTRR routinesAaron Durbin
The amd_mtrr.c file contains a copy of the fixed MTRR algorithm. However, the AMD code needs to handle the RdMem and WrMem attribute bits in the fixed MTRR MSRs. Instead of duplicating the code with the one slight change introduce a Kconfig option, X86_AMD_FIXED_MTRRS, which indicates that the RdMem and WrMem fields need to be handled for writeback fixed MTRR ranges. The order of how the AMD MTRR setup routine is maintained by providing a x86_setup_fixed_mtrrs_no_enable() function which does not enable the fixed MTRRs after setting them up. All Kconfig files which had a Makefile that included amd/mtrr in the subdirs-y now have a default X86_AMD_FIXED_MTRRS selection. There may be some overlap with the agesa and socket code, but I didn't know the best way to tease out the interdependency.

2012-12-12Claim the SPI bus before writes if the IMC ROM is presentMartin Roth
The SB800 and Hudson now support adding the IMC ROM which runs from the same chip as coreboot. When the IMC is running, write or erase commands sent to the spi bus will fail, and the IMC will die. To fix this, we send a request to the IMC to stop fetching from the SPI rom while we write to it. This process (in one form or another) is required for writes to the SPI bus while the IMC is running. Because the IMC can take up to 500ms to respond every time we claim the bus, this patch tries to keep the number of times we need to do that to a minimum. We only need to claim the bus on writes, and using a counter for the semaphore allows us to call in once to claim the bus at the beginning of a number of transactions and it will stay claimed until we release it at the end of the transactions. Claim() - takes up to 500ms hit claim() - no delay erase() release() claim() - no delay write() release() Release() Change-Id: I4e003c5122a2ed47abce57ab8b92dee6aa4713ed Signed-off-by: Martin Roth <martin@se-eng.com> Reviewed-on: http://review.coreboot.org/1976 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de>

As we move to supporting other systems we need to get rid of assembly where we can. The log2 function in src/lib is identical to the assembly one (tested for all 32-bit signed integers :-) and takes about 10 ns to run as opposed to 5ns for the non-portable assembly version. While speed is good, I think we can spare the 15 ns or so we add to boot time by using the C version only. Change-Id: Icafa565eae282c85fa5fc01b3bd1f110cd9aaa91 Signed-off-by: Ronald G.

2012-11-28amdk8/amdfam10: Use CAR_GLOBAL for sysinfoPatrick Georgi
This gets rid of the somewhat unstructured placement of AMD's sysinfo structure in CAR. We used to carve out some CAR space using a Kconfig variable, and then put sysinfo there manually (by "virtue" of pointer magic). Now it's a variable with the CAR_GLOBAL qualifier, and build system magic. For this, the following steps were done (but must happen together since the intermediates won't build): - Add new CAR_GLOBAL sysinfo_car - point all sysinfo pointers to sysinfo_car instead of GLOBAL_VAR - remove DCACHE_RAM_GLOBAL_VAR_SIZE - from CAR setup (no need to reserve the space) - commented out code (that was commented out for years) - only copy sizeof(sysinfo) into RAM after ram init, where before it copied the whole GLOBAL_VAR area. - from Kconfig Change-Id: I3cbcccd883ca6751326c8e32afde2eb0c91229ed Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/1887 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Reviewed-by: Marc Jones <marcj303@gmail.com>

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.

2012-07-16AMD: Fix GFXUMA with 4GB or more RAMKyösti Mälkki
Northbridge code incorrectly adjusted the last cacheable memory resource to accomodate room for UMA framebuffer. If system had 4GB or more memory that last resource is not below 4GB and not the one where UMA is located. There are three consequences: The last entry in coreboot memory table is reduced by uma_memory_size. Due the incorrect code in northbridge code state.tomk, end of last resource below 4GB, had not been adjusted. Incrementing that by uma_memory_size diverts a region possibly claimed for MMIO to RAM, as TOP_MEM is written. Since the UMA framebuffer did not have IORESOURCE_CACHEABLE, it was ignored from the MTRR setup and not set uncacheable. The setting of TOP_MEM and TOP_MEM2, as well as all the MTRRs, should be copied from BSP to all APs instead of deriving the data separately for each Logical CPU.
