2023-10-16mb/google/rex/var/rex: Configure cpu power limits by battery statusJamie Ryu
When battery level is below critical level or battery is not present, cpus need to run with a power optimized configuration to avoid platform instabilities. This will check the current battery status and configure cpu power limits properly. BUG=b:296952944 TEST=Build rex0 and check cpu power limits are configured with a performance efficient configuration and the platform boots to OS if battery level is above the critical level. And check cpu power limits are configured with a power optimized configuration and boots to OS without an issue if battery is not present or battery level is at or below critical level.

2023-10-10mb/google/dedede: Wait for HPD on dibbi variantsReka Norman
Some Type-C monitors do not immediately assert HPD. If we enter FSP-S before HDP is asserted, display initialisation may fail. So wait for HPD. This is similar to commit b40c6009141e ("mainboard/hatch: Fix puff DP output on cold boots") on puff, except we don't use google_chromeec_wait_for_displayport() since that EC command was removed for TCPMv2 (https://crrev.com/c/4221975). Instead we use the HPD signals only. By waiting for any HPD signal (Type-C or HDMI), we skip waiting if HDMI is connected, which is the same behaviour as puff and fizz. TEST=On dibbi, connect a display via a Type-C to HDMI dongle and check the dev and recovery screens are now displayed correctly. Also check the logs in the following cases: Cold reboot in dev mode, Type-C to HDMI dongle: HPD ready after 800 ms Warm reboot in dev mode, Type-C to HDMI dongle: HPD ready after 0 ms Cold/warm reboot in dev mode, direct Type-C: HPD ready after 0 ms Cold/warm reboot in dev mode, direct HDMI: HPD ready after 0 ms Cold/warm reboot in dev mode, no display: HPD not ready after 3000 ms.

This is because of existing temperature thresholds of TSR0 and TSR1 sensors are set at 45C to start fan.

2023-10-04soc/amd: rework SPL file override and SPL fusing handlingFelix Held
The SPL_TABLE_FILE and SPL_RW_AB_TABLE_FILE Kconfig options provide a way to override the default SPL file configured in the SoC's fw.cfg file by passing the '--spl-table' parameter to amdfwtool which will then use the override instead of the SPL file from the fw.cfg file. When SPL*_TABLE_FILE is an empty string, the corresponding add_opt_prefix call in the makefile will result in no '--spl-table' parameter being passed to amdfwtool, so it'll use the default SPL file from fw.cfg. In order to not pass an SPL override by default, remove the default from the SPL_TABLE_FILE in the SoC's Kconfig. The SoC default pointed to the same SPL file as in fw.cfg file anyway. Now only when a mainboard sets this option to point to a file, that file will be used as an override. This override is used to include a special SPL file needed for the verstage on PSP case on the Chromebooks. Since SPL_TABLE_FILE is an empty string by default, neither the SPL_TABLE_FILE Kconfig option nor it being evaluated in the Makefile need to be guarded by HAVE_SPL_FILE, so remove the dependency in the Kconfig and the ifeq in the Makefile. Before this patch, the HAVE_SPL_FILE option controlled two things that shouldn't be controlled by the same Kconfig option: Only when HAVE_SPL_FILE was set to y, the SPL_TABLE_FILE override was taken into account, and it also controls if spl_fuse.c got added to the build which when added will send the SPL fusing command to the PSP. So the case of needing an SPL file override, but not updating the SPL fuses wasn't supported before. The SPL file in the amdfw part will be used by the PSP bootloader for the anti-rollback feature which makes sure that the SPL file version isn't lower than what is in the SPL fuses. For this the SPL file needs to be present in the PSP directory table. The SPL version check happens way before we're running code on the x86 cores. The SPL fusing PSP command that can be sent by coreboot will tell the PSP to update the SPL fuses so that the fused minimal SPL version will be updated to the current SPL version. Since the former HAVE_SPL_FILE option now only controls if the SPL fusing command will be sent to the PSP mailbox, rename it to PERFORM_SPL_FUSING to clarify what this will do and update the help text correctly describe what this does. TEST=With INCLUDE_CONFIG_FILE set to n, timeless builds for both Birman with Phoenix APU and Skyrim result in identical binaries.

ASPM on the WLAN PCIe bus introduces large latency spikes, which can be measured with cyclictest: $ cyclictest --policy=rr --priority=12 --interval=10000 --threads=1 --loops=6000 Disabling ASPM for WLAN reduces the latency spikes from 2,500-3,000 usec down to 35-65 usec. These latency spikes can impact the user when real-time processes like Audio (cras) are starved of CPU time, leading to buffer underruns resulting in crackling/distorted audio.

The following features have been tested on PureOS: - USB: front USB3, rear USB3, USB2 header on board - SATA: 8x SATA ports, one M.2 M-key shared with SATA0 - PCIe: two PEG slots, one PCIe slot from PCH, and one M.2 M-key - Network: 2x GbE - Video: BMC VGA and IPMI - Serial: Physical serial port, provided by BMC SuperIO - Hardware monitor - POST code display - TPM2 These binaries are extracted from the original BIOS: - Intel Management Engine - Intel Firmware Descriptor This was developed and tested on a Librem L1UM v2 using a Core i7-9700 CPU. Native graphics init works for the Aspeed AST2500 BMC. For development, the serial port console works from bootblock. Early init waits for the BMC to finish booting since this is required for serial port output.

If the TPM (and underlying I2C controller) hasn't already been setup in verstage, it will fail to do so in ramstage since the I2C controller has not yet been initialized.
