Change in coreboot[4.11_branch]: soc/fsp_broadwell_de: read SPD 3 times and pick the majority element
by David Hendricks (Code Review) 09 Jun '23

09 Jun '23

Hello Andrey Petrov, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/37858 to review the following change. Change subject: soc/fsp_broadwell_de: read SPD 3 times and pick the majority element ...................................................................... soc/fsp_broadwell_de: read SPD 3 times and pick the majority element On the platform we consistently observe errneous reads of SPD data over IMC's SMBus. Since DDR4 SPD does not include CRC checksum for "Manufacturing Information" we can not determine serial/part numbers reliable. The root cause for SMBus errors is unknown. The corruption happens in 1 byte only with 3-4 bits flipped. Interestingly this happens after fixed amount of time, in case of tight-loop reads about every 3 seconds with almost exactly same number of CPU cycles, or multiples of that number. The stop-gap solution is to read data 3 times and pick out the prevalent member TEST=tested on OCP monolake Signed-off-by: Andrey Petrov <anpetrov(a)fb.com> Change-Id: If145cec2766f03412e33c98befb1d98b87306615 --- M src/soc/intel/fsp_broadwell_de/smbus-imc.c 1 file changed, 44 insertions(+), 5 deletions(-) git pull ssh://review.coreboot.org:29418/coreboot refs/changes/58/37858/1 diff --git a/src/soc/intel/fsp_broadwell_de/smbus-imc.c b/src/soc/intel/fsp_broadwell_de/smbus-imc.c index 61dc080..f483aae 100644 --- a/src/soc/intel/fsp_broadwell_de/smbus-imc.c +++ b/src/soc/intel/fsp_broadwell_de/smbus-imc.c @@ -13,6 +13,7 @@ * GNU General Public License for more details. */ +#include <console/console.h> #include <stddef.h> #include <device/pci_def.h> #include <device/early_smbus.h> @@ -20,6 +21,33 @@ #include <soc/pci_devs.h> #include <spd.h> +#define VOTE_ELEMENTS 3 + +static bool vote(uint16_t *arr, uint8_t n, uint8_t *res_idx) +{ + int maxcount = 0; + int index = -1; + + for(int i = 0; i < n; i++) { + int count = 0; + for(int j = 0; j < n; j++) { + if(arr[i] == arr[j]) + count++; + } + if(count > maxcount) { + maxcount = count; + index = i; + } + } + + if (maxcount > n/2) { + *res_idx = index; + return true; + } + + return false; +} + /* read word, return value on success */ uint16_t smbus_read_word(u32 smbus_dev, u8 addr, u8 offset) { @@ -36,13 +64,24 @@ /* read byte, return value on success */ uint8_t smbus_read_byte(u32 smbus_dev, u8 addr, u8 offset) { - uint16_t res = 0; + uint16_t res[VOTE_ELEMENTS] = {0}; + uint8_t idx = 0; - if (imc_smbus_spd_xfer(IMC_DEV, addr, offset, IMC_DEVICE_EEPROM, IMC_DATA_BYTE, - IMC_CONTROLLER_ID0, IMC_READ, &res) - == 0) { - return res; + for (int i = 0; i < ARRAY_SIZE(res); i++) { + if (imc_smbus_spd_xfer(IMC_DEV, + addr, offset, IMC_DEVICE_EEPROM, IMC_DATA_BYTE, + IMC_CONTROLLER_ID0, IMC_READ, &res[i]) != 0) { + return 0; + } } + + /* vote for majority element, pick 1 out of 3 */ + if (vote(res, ARRAY_SIZE(res), &idx)) { + return res[idx]; + } + + printk(BIOS_ALERT, "IMC: read failure, couldn't vote for correct byte\n"); + return 0; } -- To view, visit https://review.coreboot.org/c/coreboot/+/37858 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: coreboot Gerrit-Branch: 4.11_branch Gerrit-Change-Id: If145cec2766f03412e33c98befb1d98b87306615 Gerrit-Change-Number: 37858 Gerrit-PatchSet: 1 Gerrit-Owner: David Hendricks <david.hendricks(a)gmail.com> Gerrit-Reviewer: Andrey Petrov <anpetrov(a)fb.com> Gerrit-MessageType: newchange

Kane Chen has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/37865 ) Change subject: [under test]mb/google/hatch: Program gpio clk power gating settings in SPI0 PS3/PS0 ...................................................................... [under test]mb/google/hatch: Program gpio clk power gating settings in SPI0 PS3/PS0 With PchPmSlpS0Vm075VSupport FSP UPD set, SoC requires gpio clk to be power gated. But when gpio clk is power gated, it requires longer interrupt assertion from device. This commit provides a way to set gpio clk power gating settings in SPIO PS0/PS3 so that cr50 doesn't need longer interrupt assertion and SoC can still enter runtime s0ix with PchPmSlpS0Vm075VSupport set.

Change in coreboot[master]: security: Move TS_{START,END}_TPMINIT out of vboot
