Also, like IPMB, the address byte is in its message format, ++it needs it to do checksum. ++ ++For messages are time related, so this backend will flush the oldest message ++to queue the newest one. ++ ++Link ++---- ++`Intelligent Platform Management Bus ++Communications Protocol Specification ++<https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/ipmp-spec-v1.0.pdf>`_ ++ ++`Management Component Transport Protocol (MCTP) ++SMBus/I2C Transport Binding Specification ++<https://www.dmtf.org/sites/default/files/standards/documents/DSP0237_1.1.0.pdf>`_ ++ ++How to use ++---------- ++For example, the I2C5 bus has slave address 0x10, the below command will create ++the related message queue interface: ++ ++ echo slave-mqueue 0x1010 > /sys/bus/i2c/devices/i2c-5/new_device ++ ++Then you can dump the messages like this: ++ ++ hexdump -C /sys/bus/i2c/devices/5-1010/slave-mqueue ++ ++Code Example ++------------ ++*Note: call 'lseek' before 'read', this is a requirement from kernfs' design.* ++ ++:: ++ ++ #include <sys/types.h> ++ #include <sys/stat.h> ++ #include <unistd.h> ++ #include <poll.h> ++ #include <time.h> ++ #include <fcntl.h> ++ #include <stdio.h> ++ ++ int main(int argc, char *argv[]) ++ { ++ int i, r; ++ struct pollfd pfd; ++ struct timespec ts; ++ unsigned char data[256]; ++ ++ pfd.fd = open(argv[1], O_RDONLY | O_NONBLOCK); ++ if (pfd.fd < 0) ++ return -1; ++ ++ pfd.events = POLLPRI; ++ ++ while (1) { ++ r = poll(&pfd, 1, 5000); ++ ++ if (r < 0) ++ break; ++ ++ if (r == 0 || !(pfd.revents & POLLPRI)) ++ continue; ++ ++ lseek(pfd.fd, 0, SEEK_SET); ++ r = read(pfd.fd, data, sizeof(data)); ++ if (r <= 0) ++ continue; ++ ++ clock_gettime(CLOCK_MONOTONIC, &ts); ++ printf("[%ld.%.9ld] :", ts.tv_sec, ts.tv_nsec); ++ for (i = 0; i < r; i++) ++ printf(" %02x", data[i]); ++ printf("\n"); ++ } ++ ++ close(pfd.fd); ++ ++ return 0; ++ } ++ ++Result ++------ ++*./a.out "/sys/bus/i2c/devices/5-1010/slave-mqueue"* ++ ++:: ++ ++ [10183.232500449] : 20 18 c8 2c 78 01 5b ++ [10183.479358348] : 20 18 c8 2c 78 01 5b ++ [10183.726556812] : 20 18 c8 2c 78 01 5b ++ [10183.972605863] : 20 18 c8 2c 78 01 5b ++ [10184.220124772] : 20 18 c8 2c 78 01 5b ++ [10184.467764166] : 20 18 c8 2c 78 01 5b ++ [10193.233421784] : 20 18 c8 2c 7c 01 57 ++ [10193.480273460] : 20 18 c8 2c 7c 01 57 ++ [10193.726788733] : 20 18 c8 2c 7c 01 57 ++ [10193.972781945] : 20 18 c8 2c 7c 01 57 ++ [10194.220487360] : 20 18 c8 2c 7c 01 57 ++ [10194.468089259] : 20 18 c8 2c 7c 01 57 ++ [10203.233433099] : 20 18 c8 2c 80 01 53 ++ [10203.481058715] : 20 18 c8 2c 80 01 53 ++ [10203.727610472] : 20 18 c8 2c 80 01 53 ++ [10203.974044856] : 20 18 c8 2c 80 01 53 ++ [10204.220734634] : 20 18 c8 2c 80 01 53 ++ [10204.468461664] : 20 18 c8 2c 80 01 53 +diff --git a/drivers/i2c/Kconfig b/drivers/i2c/Kconfig +index abedd55a1264..49a2379876c6 100644 +--- a/drivers/i2c/Kconfig ++++ b/drivers/i2c/Kconfig +@@ -119,6 +119,29 @@ if I2C_SLAVE + config I2C_SLAVE_EEPROM + tristate "I2C eeprom slave driver" + ++config I2C_SLAVE_MQUEUE_MESSAGE_SIZE ++ int "The message size of I2C mqueue slave" ++ default 120 ++ ++config I2C_SLAVE_MQUEUE_QUEUE_SIZE ++ int "The queue size of I2C mqueue slave" ++ default 32 ++ help ++ This number MUST be power of 2. ++ ++config I2C_SLAVE_MQUEUE ++ tristate "I2C mqueue (message queue) slave driver" ++ help ++ Some protocols over I2C are designed for bi-directional transferring ++ messages by using I2C Master Write protocol.
