2023-04-06soc/intel/cmn/cpu: Add function to disable 3-strike CATERRSubrata Banik
In Intel designs, internal processor errors, such as a processor instruction retirement watchdog timeout (also known as a 3-strike timeout) will cause a CATERR assertion and can only be recovered from by a system reset. This patch prevents the Three Strike Counter from incrementing (as per Intel EDS doc: 630094), which would help to disable Machine Check Catastrophic error. It will provide more opportunity to collect more useful CPU traces for debugging. TEST=Able to build and boot google/rex.

2023-04-05soc/intel/common/block/pcie/rtd3: Add root port mutex supportCliff Huang
When 'use_rp_mutex' (default = 0) is set in the device tree, a root port mutex will be added. This mutex is used in _ON and _OFF method, where the GPIO reset and/or enable GPIO value is changed. The companion driver, such as WWAN driver, needs to acquire this root port mutex when accessing the same GPIO pins. Using this common mutex prevents those invoked methods from being called from different thread while one is not completed. An example is that WWAN driver calling _RST method to reset the device and does remove/rescan for the device while the pm runtime work might call RTD3 _OFF. For those root port without additional driver, this mutex is not needed. BRANCH=firmware-brya-14505.B TEST=boot to OS and check the generated SSDT table for the root port. The RPMX mutex should be generated and _ON and _OFF should use this mutex.

2023-03-31soc/intel/cmn/cse: Handle EOP completion asynchronouslyJeremy Compostella
coreboot supports three instances of sending EOP: 1. At CSE `.final' device operation 2. Early as with Alder Lake in chip_operations.init if `SOC_INTEL_CSE_SEND_EOP_EARLY' is selected 3. At BS_PAYLOAD_BOOT as designed for Meteor Lake if `SOC_INTEL_CSE_SEND_EOP_LATE' is selected Currently, Alder Lake uses #3 as it results in better and more stable boot time. However, what would deliver even better result is to not actively wait for CSE completion. This patch introduces a new `SOC_INTEL_CSE_SEND_EOP_ASYNC' Kconfig which split the action of sending EOP request and receiving EOP completion response from the CSE. This patch used in conjunction with #1 can significantly improves the overall boot time on a Raptor Lake design. For example `SOC_INTEL_CSE_SEND_EOP_ASYNC' on a skolas board can deliver up to 36 ms boot time improvement as illustrated below. | # | Late EOP | Async EOP | |----------+----------+-----------| | 1 | 1020.052 | 971.272 | | 2 | 1015.911 | 971.821 | | 3 | 1038.415 | 1021.841 | | 4 | 1020.657 | 993.751 | | 5 | 1065.128 | 1020.951 | | 6 | 1037.859 | 1023.326 | | 7 | 1042.010 | 984.412 | |----------+----------+-----------| | Mean | 1034.29 | 998.20 | | Variance | 4.76 % | 5.21 % | The improvement is not stable but comparing coreboot and FSP performance timestamps demonstrate that the slowness is caused by a lower memory frequency (SaGv point) at early boot which is not an issue addressed by this patch. We also observe some improvement on an Alder Lake design. For example, the same configuration on a kano board can deliver up to 10 ms boot time improvement as illustrated below. | # | Late EOP | Async EOP | |----------+----------+-----------| | 0 | 1067.719 | 1050.106 | | 1 | 1058.263 | 1056.836 | | 2 | 1064.091 | 1056.709 | | 3 | 1068.614 | 1055.042 | | 4 | 1065.749 | 1056.732 | | 5 | 1069.838 | 1057.846 | | 6 | 1066.897 | 1053.548 | | 7 | 1060.850 | 1051.911 | |----------+----------+-----------| | Mean | 1065.25 | 1054.84 | The improvement is more limited on kano because a longer PCIe initialization delays EOP in the Late EOP configuration which make it faster to complete. CSME team confirms that: 1. End-Of-Post is a blocking command in the sense that BIOS is requested to wait for the command completion before loading the OS or second stage bootloader. 2. The BIOS is not required to actively wait for completion of the command and can perform other operations in the meantime as long as they do not involve HECI commands. On Raptor Lake, coreboot does not send any HECI command after End-Of-Post. FSP-s code review did not reveal any HECI command being sent as part of the `AFTER_PCI_ENUM', `READY_TO_BOOT' or `END_OF_FIRMWARE' notifications. If any HECI send and receive command has been sent the extra code added in `cse_receive_eop()' should catch it. According to commit 387ec919d9f7 ("soc/intel/alderlake: Select SOC_INTEL_CSE_SEND_EOP_LATE"), FSP-silicon can sometimes (on the first boot after flashing of a Marasov board for instance) request coreboot to perform a global request out of AFTER_PCI_ENUM notification. Global request relies on a HECI command. Even though, we tested that it does not create any issue, `SOC_INTEL_CSE_SEND_EOP_ASYNC' flag should not be associated to the `SOC_INTEL_CSE_SEND_EOP_EARLY' flag to prevent potential a global reset command to "conflict" with the EOP command. BUG=b:276339544 BRANCH=firmware-brya-14505.B TEST=Tests on brya0 with and `SOC_INTEL_CSE_SEND_EOP_ASYNC' show End-Of-Post sent soon after FSP-s and EOP message receive at `BS_PAYLOAD_BOOT'. Verify robustness by injecting a `GET_BOOT_STATE' HECI command with or without `heci_reset'. The implementation always successfully completed the EOP before moving to the payload. As expected, the boot time benefit of the asynchronous solution was under some injection scenario undermined by this unexpected HECI command.

2023-03-13soc/intel/cmn/tom: Cache TOM region earlySubrata Banik
This patch implements a module that can store the top_of_ram (TOM) address into non-volatile space (CMOS) during the first boot and use it across all consecutive boot. As top_of_ram address is not known until FSP-M has exited, it results into lacking of MTRR programming to cache the 16 MB TOM, hence accessing that range during FSP-M and/or late romstage causing long access times. Purpose of this driver code is to cache the TOM (with a fixed size of 16MB) for all consecutive boots even before calling into the FSP. Otherwise, this range remains un-cached until postcar boot stage updates the MTRR programming. FSP-M and late romstage uses this uncached TOM range for various purposes (like relocating services between SPI mapped cached memory to DRAM based uncache memory) hence having the ability to cache this range beforehand would help to optimize the boot time (more than 50ms as applicable).

2023-02-16soc/intel/common/block/pcie/rtd3: Fix root port _ON logicCliff Huang
_ON() calls _STA() at the beginning. If _STA() indicates the device is ON, it exits immediately. The solution is to move this _STA() check into the ONSK logic. In general cases, ONSK remains '0'. NOTE: RTD3 provides a way to skip _OFF() and _ON() methods following by a device reset such as WWAN device. When such device calls its _RST(), it increments OFSK. When the following _OFF() is called, it was scheduled to skip, it will also increments ONSK. Similarly, when the following _ON() is called, it checks if the previous _OFF was skipped or not. If skipped, it needs to do the same. In normal suspend/resume cases, these two variables remains '0'. No _OFF() and _ON() calls are skipped. entire generated code: Method (_ON, 0, Serialized) // _ON_: Power On { If ((ONSK == Zero)) { Local0 = \_SB.PCI0.RP01.RTD3._STA () If ((Local0 == One)) { Return (One) } Acquire (\_SB.PCI0.R3MX, 0xFFFF) EMPG = Zero Local7 = 0x06 While ((Local7 > Zero)) { If ((AMPG == Zero)) { Break } Sleep (0x10) Local7-- } Release (\_SB.PCI0.R3MX) \_SB.PCI0.PMC.IPCS (0xAC, Zero, 0x10, 0x00000020, 0x00000020, 0x00000020, 0x00000020) \_SB.PCI0.STXS (0x015E) If ((NCB7 == One)) { L23R = One Local7 = 0x14 While ((Local7 > Zero)) { If ((L23R == Zero)) { Break } Sleep (0x10) Local7-- } NCB7 = Zero Local7 = 0x08 While ((Local7 > Zero)) { If ((LASX == One)) { Break } Sleep (0x10) Local7-- } } } Else { ONSK-- } } BUG=b:249931687 BUG=b:241850118 TEST=Use above functions and check the generated SSDT table after OS boot.

Since the `Update_Output' function does not return any value, this patch modifies the `gma_gfxstop' prototype accordingly. This does not have any impact as the return value was not used anyway.

This patch calls into `pmc_clear_pmcon_pwr_failure_sts()` to clear GEN_PMCON_x register status bits after determining the `prev_sleep_state`.

2023-01-09soc/intel/common: Fix cpu index calculationSridhar Siricilla
get_cpu_index() helper function returns cpu's index based on it's APIC id position from the ascending order list of cpus' APIC IDs. In order to calculate the cpu's index, the helper function needs to traverse through each cpu node to find their APIC IDs. So, the function traverse the CPU node list from the cpu whose APIC ID is 0 assuming it is the first cpu node in the list. This logic works fine where BSP's APIC ID is 0. But, starting from MTL, APIC ID for BSP need not be 0 as APIC ID numbering first get assigned for CPU Die Efficient cores, then Performance cores. Please refer section# 6.1 of doc#643504 for more details on APIC IDs. Considering the APIC Id allotment for MTL cores, as existing code traversing begins from the cpu that has APIC Id#0 which may not be the first cpu node in the list so index calculation results in wrong value. The patch addresses above described issue by traversing all the CPU nodes to calculate the cpu index. Also, prevents inconsistent report of /sys/devices/system/cpu/cpu*/cpufreq/* and /sys/devices/system/cpu/cpuXX/acpi_cppc on each reboot. TEST=Verified that the get_cpu_index helper function returns the correct index id for a CPU on Rex.
