2014-04-13cimx/sb800 boards: Don't require ide.asl on boards without IDEEdward O'Callaghan
Not all boards which use the AMD cimx/sb800 southbridge have IDE. However, the southbridge's asl included an 'ide.asl' file which had to be present in $(mainboard_dir)/acpi. Address this issue by including ide.asl only in boards which have IDE, and remove it from all other cimx/sb800 boards.

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>
2013-03-15Persimmon DSDT: Remove INI method from AZHD deviceMike Loptien
I am removing the _INI method from the AZHD device because it does not seem to do anything and causes errors in the FWTS[1] (Firmware Test Suite) test 'method'. The INI method performs device specific initialization and is run when OSPM loads a description table. It must only access OperationRegions that have been indicated as available by the _REG (Region) method. We do not have a _REG method and during my testing, I added a REG method but it did not seem to make a difference in the PCI register space. The bit fields defined as NSDI (Disable No Snoop), NSDO (Disable No Snoop Override), and NSEN (Enable No Snoop Request) do not ever get written from their default values. And writing to these bit fields does not seem to be necessary because I did not notice any change in audio functionality. In an effort to clean up as many FWTS errors as possible, I propose removing this method altogether. I have seen no change in operation (audio works with and without this method) and there does not seem to be any change in lspci or dmesg.

2013-03-15Persimmon DSDT: Add OSC methodMike Loptien
The _OSC method is used to tell the OS what capabilities it can take control over from the firmware. This method is described in chapter 6.2.9 of the ACPI spec v3.0. The method takes 4 inputs (UUID, Rev ID, Input Count, and Capabilities Buffer) and returns a Capabilites Buffer the same size as the input Buffer. This Buffer is generally 3 Dwords long consisting of an Errors Dword, a Supported Capabilities Dword, and a Control Dword. The OS will request control of certain capabilities and the firmware must grant or deny control of those features. We do not want to have control over anything so let the OS control as much as it can. The _OSC method is required for PCIe devices and dmesg checks for its existence and issues an error if it is not found.

2013-03-08Persimmon DSDT: Add secondary bus range to PCI0Mike Loptien
Adding the 'WordBusNumber' macro to the PCI0 CRES ResourceTemplate in the Persimmon DSDT. This sets up the bus number for the PCI0 device and the secondary bus number in the CRS method. This change came in response to a 'dmesg' error which states: '[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS' By adding the 'WordBusNumber' macro, ACPI can set up a valid range for the PCIe downstream busses, thereby relieving the Linux kernel from "guessing" the valid range based off _BBN or assuming [0-0xFF]. The Linux kernel code that checks this bus range is in `drivers/acpi/pci_root.c`. PCI busses can have up to 256 secondary busses connected to them via a PCI-PCI bridge. However, these busses do not have to be sequentially numbered, so leaving out a section of the range (eg. allowing [0-0x7F]) will unnecessarily restrict the downstream busses. This change will apply to other AMD mainboards and will be in a different commit.

2013-02-25AMD Fam14 boards: Set P_BLK length to 6 for all processorsPaul Menzel
Currently on for example on AMD Persimmon and ASRock E350M1 Linux complains, that the PBLK length is invalid [1]. ACPI: Invalid PBLK length [0] Consequently, frequency scaling might not work correctly, though for these two boards it seems to work according to PowerTOP. Indeed, according to the ACPI specification [2], setting PBlockLength to 0 is only allowed if there is no PBlockAddress. Otherwise it has to be set to 6. 18.5.93 Processor (Declare Processor) […] PBlockAddress provides the system I/O address for the processors register block. Each processor can supply a different such address. PBlockLength is the length of the processor register block, in bytes and is either 0 (for no P_BLK) or 6. With one exception, all processors are required to have the same PBlockLength. The exception is that the boot processor can have a non-zero PBlockLength when all other processors have a zero PBlockLength. It is valid for every processor to have a PBlockLength of 0. And that is exactly what Linux is checking in `drivers/acpi/processor_driver.c` [3]. static int acpi_processor_get_info(struct acpi_device *device) { […] /* * On some boxes several processors use the same processor bus id. * But they are located in different scope. For example: * \_SB.SCK0.CPU0 * \_SB.SCK1.CPU0 * Rename the processor device bus id. And the new bus id will be * generated as the following format: * CPU+CPU ID. */ sprintf(acpi_device_bid(device), "CPU%X", pr->id); ACPI_DEBUG_PRINT((ACPI_DB_INFO, "Processor [%d:%d]\n", pr->id, pr->acpi_id)); if (!object.processor.pblk_address) ACPI_DEBUG_PRINT((ACPI_DB_INFO, "No PBLK (NULL address)\n")); else if (object.processor.pblk_length != 6) printk(KERN_ERR PREFIX "Invalid PBLK length [%d]\n", object.processor.pblk_length); else { pr->throttling.address = object.processor.pblk_address; pr->throttling.duty_offset = acpi_gbl_FADT.duty_offset; pr->throttling.duty_width = acpi_gbl_FADT.duty_width; pr->pblk = object.processor.pblk_address; /* * We don't care about error returns - we just try to mark * these reserved so that nobody else is confused into thinking * that this region might be unused.. * * (In particular, allocating the IO range for Cardbus) */ request_region(pr->throttling.address, 6, "ACPI CPU throttle"); } […] } This issue has proliferated to all AMD based boards so fix it for all of them by setting P_BLK length to 6. The DSDT of for example AMD Parmer and AMD Thatcher also set it to 6 everywhere so this solution is taken instead of setting the P_BLK system I/O base to 0 for all but the first processor which is how it is done for earlier AMD based boards. As note having to set this manually should not be needed and this should be autogenerated as done for most of the Intel boards and the AMD K8 based boards (`src/cpu/amd/model_fxx/powernow_acpi.c`).

2013-02-25AMD boards: ACPI DSDT: Use COREBOOT for the OEM Table ID fieldPaul Menzel
The DSDT header contains the fields OEMID and OEM Table ID. See for example ACPI specification 4.0a [1] 5.2.11.1 Differentiated System Description Table (DSDT) on page 135. There Table 5-16 contains the descriptions. Field Byte Length Byte Offset Description =================================================== OEMID 6 10 OEM ID OEM Table ID 8 16 The manufacture model ID. Currently in coreboot there is no common method what to put in these fields. Mostly Intel based boards populate it with "CORE " ore "COREv4" and AMD based boards populate it with the board vendor and model number, abbreviated appropriately to fit into these fields. On most boards the proprietary vendor BIOS seems to leave these fields – displayed with `sudo dmidecode` under System Information – blank To Be Filled By O.E.M. and fill out the Base Board Information with the board vendor and model name. In [2] Jens Rottmann argues that the this is really just the table ID used for naming it and that »99% of the DSDT code is not board specific«. Both approaches seem to have their advantages, but using the second one, developers often seem to forget to update them (for example AMD Thather). The current situation is at least not optimal. and therefore at least unify the string in the OEM Table ID. If unifying the OEM ID is also a good idea this should be done too. If later on it should be decided that the board vendor and model should be used again, this should be somehow derived from Kconfig. The following command was used for the change [3]. $ git grep -l '\/\* TABLE ID \*\/' | xargs sed -i '/TABLE ID/s/"\([^"]*\)"/"COREBOOT"/' This patch is split out from [2].
