2013-12-12HDA: Enable Mini-HDA and fix up PCH-HDA initDuncan Laurie
The SystemAgent contains a mini-hd audio controller at PCI 0:3.0 which uses the same verb table init sequence as the southbridge. In order to avoid two copies of the verb table loading code I separated out the HDA verb table functions into a file that can be re-used and then added a minihd driver to the haswell northbridge. The minihd verb table is the same across devices so it can live within the minihd driver rather than needing to be specified in each separate mainboard. I also fixed up the driver for lynxpoint HDA by following the reference code. Without HDMI cable plugged in driver does not find any codec, and it does not seem to re-probe when HDMI is connected. We may be missing kernel patches for this. hda-intel 0000:00:03.0: no codecs found! With a basic kernel patch to add 0x0a0c device ID to HDA driver and with HDMI cable connected it is much happier: snd_hda_intel 0000:00:03.0: irq 60 for MSI/MSI-X input: HDA Intel MID HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:03.0/sound/card0/input9 snd_hda_intel 0000:00:1b.0: irq 61 for MSI/MSI-X input: HDA Intel PCH Mic as /devices/pci0000:00/0000:00:1b.0/sound/card1/input10 input: HDA Intel PCH Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card1/input11 Change-Id: Ifa587984be4fc2801704a0368b9cdf8379c2450e Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/59336 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/4318 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

Some new fields were added to the edid data structure, and the edid code was changed to put estimated values into those fields which were ultimately passed into depthcharge or other payloads. On snow we do things different and just declare an edid structure statically which didn't have those members. The rows and columns of the graphics console were 0, and that confused the framebuffer driver and made it loop forever.

2013-12-07peppy: Enable power limiting for thermal controlDuncan Laurie
Limit power to 12W at 73C and remove limit at 68C. To have the CPU consume maximum power it is necessary to stress both the CPU and the GPU. Bastion (chrome.supergiantgames.com) and/or webglsamples.googlecode.com can be useful for this. Testing this properly requires a script to report the running average power readings. The watch_power.sh script is attached to this issue in the partner tracker. 1) Run watch_power.sh continuously: localhost ~ # watch -n 0 bash -e /tmp/watch_power.sh 2) Start Bastion (or other stress apps). The power draw should be close to 15W if under enough load. 3) Watch until temperature climbs above 73C and is caught by the thermal zone 10 second poll, this can be sped up by blocking or removing the fan. 4) The ACPI thermal zone states should change to reflect that active[2] is now enabled and power consumption should drop to 12W. 5) Stop the stress apps and wait until the CPU cools off again, enable the fan again if it was removed. 6) The ACPI thermal zone state should switch back to active[3].

On some systems there may be 2GB SKU that is the same as the 4GB SKU but just one channel of memory. In that case we need to ensure that both copies of the same SPD source end up populated by ensuring that repeated entries are included by using $+ instead of $^. Alternatively we could do the check inside romstage, but it is already set to behave this way if the SPD gets populated correctly. I changed spd_index to 3 in falco romstage to force it to pretend it was a 2GB config of the same memory, then booted to ensure it was indeed limited to 2GB. memcfg channel[0] config (00780008): ECC inactive enhanced interleave mode on rank interleave on DIMMA 2048 MB width x16 single rank, selected DIMMB 0 MB width x16 single rank memcfg channel[1] config (00600000): ECC inactive enhanced interleave mode on rank interleave on DIMMA 0 MB width x8 single rank, selected DIMMB 0 MB width x8 single rank Change-Id: Ibfe5051ccda2fe69e8caff3f3c264116e3411c65 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/59483 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Tested-by: Jay Kim <yongjaek@chromium.org> Reviewed-on: http://review.coreboot.org/4319 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2013-11-25lynxpoint: Change SerialIO device enable reporting to ACPIDuncan Laurie
In order to report whether coreboot enabled a SerialIO device in ACPI mode we had been relying on reading NVS in the _STA method for the SerialIO device. The ACPI _STA method has restrictions on what it can access and is unable to access OperationRegions outside its scope which means it should not be trying to read NVS. This change adds a new SSDT to the ACPI tables and fills it with constants that indicate whether or not a device is enabled in ACPI mode. The ACPI code is changed to read these variables from the SSDT and use that instead of trying to query a variable in NVS. Attempt to use lpt-clk driver to probe the device clocks for SerialIO devices and see that the kernel does not complain about accessing the GNVS region.

Now that that capability has been added, we can rewrite the small portion of the the tps65090 we actually used but using the EC passthrough commands. Also, we should not be configuring the hardware display port hotplug detect line since we're using it as a GPIO for other purposes. The GPIO we're using instead defaults to being an input, but to be safe we should probably explicitly configure it as one anyway.

2013-07-10exynos5250: De-switch-ify the pinmux configuration code.Gabe Black
The pinmux code for the exynos5250 was all bundled into a single, large function which contained a switch statement that would set up the pins for different peripherals within the SOC. There was also a "flags" parameter, the meaning of which, if any, depended on which peripheral was being set up. There are several problems with that approach. First, the code is inefficient in both time and space. The caller knows which peripheral it wants to set up, but that information is encoded in a constant which has to be unpacked within the function before any action can be taken. If there were a function per peripheral, that information would be implicit. Also, the compiler and linker are forced to include the entire function with all its cases even if most of them are never called. If each peripheral was a function, the unused ones could be garbage collected. Second, it would be possible to try to set up a peripheral which that function doesn't know about, so there has to be additional error checking/handling. If each peripheral had a function, the fact that there was a function to call at all would imply that the call would be understood. Third, the flags parameter is fairly opaque, usually doesn't do anything, and sometimes has to have multiple values embedded in it. By having separate functions, you can have only the parameters you actually want, give them names that make sense, and pass in values directly. Fourth, having one giant function pretends to be a generic, portable API, but in reality, the only way it's useful is to call it with constants which are specific to a particular implementation of that API. It's highly unlikely that a bit of code will need to set up a peripheral but have no idea what that peripheral actually is. Call sights for the prior pinmux API have been updated. Also, pinmux initialization within the i2c driver was moved to be in the board setup code where it really probably belongs. The function block that implements the I2C controller may be shared between multiple SOCs (and in fact is), and those SOCs may have different pinmuxes (which they do). Other places this same sort of change can be made are the pinmux code for the 5420, and the clock configuration code for both the 5250 and the 5420.
