From 67e74f6190eec7624ab3dba53fa81ffdc961029a Mon Sep 17 00:00:00 2001 From: Eric Chen Date: Wed, 30 Aug 2023 17:51:22 +0800 Subject: [PATCH] fby4: sd: Support PLDM host power control Summary: Description Implement pldm host power control handler Motivation In Yosemite4, BMC will communicate with BIC by PLDM command. This change PLDM Support host power control by setting cpld through i2c Test Plan: - host power on: pass - host power off: pass - host power cycle: pass - host power reset: pass - host graceful shutdown: pass Test Log: - host power on pldmtool raw -d 0x80 0x02 0x39 0x0 0x0 0x1 0x0 0x1 pldmtool: Tx: 81 02 39 00 00 01 00 01 pldmtool: Rx: 01 02 39 00 - host power off pldmtool raw -d 0x80 0x02 0x39 0x0 0x0 0x1 0x0 0x2 pldmtool: Tx: 81 02 39 00 00 01 00 02 pldmtool: Rx: 01 02 39 00 - host power cycle pldmtool raw -d 0x80 0x02 0x39 0x0 0x0 0x1 0x0 0x3 pldmtool: Tx: 81 02 39 00 00 01 00 03 pldmtool: Rx: 01 02 39 00 - host power reset pldmtool raw -d 0x80 0x02 0x39 0x0 0x0 0x1 0x0 0x4 pldmtool: Tx: 81 02 39 00 00 01 00 04 pldmtool: Rx: 01 02 39 00 - host power reset pldmtool raw -d 0x80 0x02 0x39 0x0 0x0 0x1 0x0 0x4 pldmtool: Tx: 81 02 39 00 00 01 00 04 pldmtool: Rx: 01 02 39 00 - host graceful shutdown pldmtool raw -d 0x80 0x02 0x39 0x0 0x0 0x1 0x0 0x5 pldmtool: Tx: 81 02 39 00 00 01 00 05 pldmtool: Rx: 01 02 39 00 --- meta-facebook/yv4-sd/src/platform/plat_init.c | 2 +- .../yv4-sd/src/platform/plat_pldm_monitor.c | 110 ++++++++++++++++++ .../yv4-sd/src/platform/plat_pldm_monitor.h | 6 +- 3 files changed, 116 insertions(+), 2 deletions(-) diff --git a/meta-facebook/yv4-sd/src/platform/plat_init.c b/meta-facebook/yv4-sd/src/platform/plat_init.c index 5ecea8af0f..d8da852ca3 100644 --- a/meta-facebook/yv4-sd/src/platform/plat_init.c +++ b/meta-facebook/yv4-sd/src/platform/plat_init.c @@ -44,7 +44,7 @@ void pal_pre_init() void pal_post_init() { plat_mctp_init(); - pldm_load_state_effecter_table(MAX_STATE_EFFECTER_IDX); + pldm_load_state_effecter_table(PLAT_PLDM_MAX_STATE_EFFECTER_IDX); pldm_assign_gpio_effecter_id(PLAT_EFFECTER_ID_GPIO_HIGH_BYTE); } diff --git a/meta-facebook/yv4-sd/src/platform/plat_pldm_monitor.c b/meta-facebook/yv4-sd/src/platform/plat_pldm_monitor.c index 0abaab8b2e..d89662a175 100644 --- a/meta-facebook/yv4-sd/src/platform/plat_pldm_monitor.c +++ b/meta-facebook/yv4-sd/src/platform/plat_pldm_monitor.c @@ -22,15 +22,33 @@ #include "pldm.h" #include "plat_gpio.h" +#include "plat_i2c.h" #include "plat_sensor_table.h" #include "plat_pldm_monitor.h" LOG_MODULE_REGISTER(plat_pldm_monitor); +#define PLAT_PLDM_POWER_ON_BUTTON_MSEC 1000 +#define PLAT_PLDM_RESET_BUTTON_MSEC 1000 +#define PLAT_PLDM_GRACEFUL_SHUTDOWN_BUTTON_MSEC 1000 +#define PLAT_PLDM_POWER_OFF_BUTTON_MSEC 6000 +#define PLAT_PLDM_POWER_CYCLE_INTERVAL_MSEC 5000 + +#define PLAT_PLDM_SEQUENCE_CNT 3 + +static uint8_t power_sequence[PLAT_PLDM_SEQUENCE_CNT] = {PLAT_PLDM_HOST_PWR_CTRL_DEFAULT, PLAT_PLDM_HOST_PWR_BTN_LOW, + PLAT_PLDM_HOST_PWR_CTRL_DEFAULT}; +static uint8_t reset_sequence[PLAT_PLDM_SEQUENCE_CNT] = {PLAT_PLDM_HOST_PWR_CTRL_DEFAULT, PLAT_PLDM_HOST_RST_BTN_LOW, + PLAT_PLDM_HOST_PWR_CTRL_DEFAULT}; + struct pldm_state_effecter_info plat_state_effecter_table[] = { [0 ...
