Routing information required to to reach the RIO device: destid - device destination ID (real for for endpoint, route for switch) hopcount - hopcount for maintenance requests (switches only) 2. device linking information: lprev - name of device that precedes the given device in the enumeration or discovery order (displayed along with of the port to which it is attached). lnext - names of devices (with corresponding port numbers) that are attached to the given device as next in the enumeration or discovery order (switches only) Signed-off-by: Alexandre Bounine <alexandre.bounine@xxxxxxx> Cc: Kumar Gala <galak@xxxxxxxxxxxxxxxxxxx> Cc: Matt Porter <mporter@xxxxxxxxxxxxxxxxxxx> Cc: Li Yang <leoli@xxxxxxxxxxxxx> Cc: Thomas Moll <thomas.moll@xxxxxxxxx> Cc: Micha Nelissen <micha@xxxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/rapidio/rio-sysfs.c | 39 +++++++++++++++++++++++++++++++++- 1 file changed, 38 insertions(+), 1 deletion(-) diff -puN drivers/rapidio/rio-sysfs.c~rapidio-add-new-sysfs-attributes drivers/rapidio/rio-sysfs.c --- a/drivers/rapidio/rio-sysfs.c~rapidio-add-new-sysfs-attributes +++ a/drivers/rapidio/rio-sysfs.c @@ -33,6 +33,8 @@ rio_config_attr(device_rev, "0x%08x\n"); rio_config_attr(asm_did, "0x%04x\n"); rio_config_attr(asm_vid, "0x%04x\n"); rio_config_attr(asm_rev, "0x%04x\n"); +rio_config_attr(destid, "0x%04x\n"); +rio_config_attr(hopcount, "0x%02x\n"); static ssize_t routes_show(struct device *dev, struct device_attribute *attr, char *buf) { @@ -52,6 +54,33 @@ static ssize_t routes_show(struct device return (str - buf); } +static ssize_t lprev_show(struct device *dev, + struct device_attribute *attr, char *buf) +{ + struct rio_dev *rdev = to_rio_dev(dev); + + return sprintf(buf, "%02d %s\n", RIO_GET_PORT_NUM(rdev->swpinfo), + (rdev->prev) ? rio_name(rdev->prev) : "host"); +} + +static ssize_t lnext_show(struct device *dev, + struct device_attribute *attr, char *buf) +{ + struct rio_dev *rdev = to_rio_dev(dev); + char *str = buf; + int i; + + if (rdev->pef & RIO_PEF_SWITCH) { + for (i = 0; i < RIO_GET_TOTAL_PORTS(rdev->swpinfo); i++) { + if (rdev->rswitch->nextdev[i]) + str += sprintf(str, "%02d %s\n", i, + rio_name(rdev->rswitch->nextdev[i])); + } + } + + return str - buf; +} + struct device_attribute rio_dev_attrs[] = { __ATTR_RO(did), __ATTR_RO(vid), @@ -59,10 +88,14 @@ struct device_attribute rio_dev_attrs[] __ATTR_RO(asm_did), __ATTR_RO(asm_vid), __ATTR_RO(asm_rev), + __ATTR_RO(lprev), + __ATTR_RO(destid), __ATTR_NULL, }; static DEVICE_ATTR(routes, S_IRUGO, routes_show, NULL); +static DEVICE_ATTR(lnext, S_IRUGO, lnext_show, NULL); +static DEVICE_ATTR(hopcount, S_IRUGO, hopcount_show, NULL); static ssize_t rio_read_config(struct file *filp, struct kobject *kobj, @@ -218,7 +251,9 @@ int rio_create_sysfs_dev_files(struct ri err = device_create_bin_file(&rdev->dev, &rio_config_attr); if (!err && (rdev->pef & RIO_PEF_SWITCH)) { - err = device_create_file(&rdev->dev, &dev_attr_routes); + err |= device_create_file(&rdev->dev, &dev_attr_routes); + err |= device_create_file(&rdev->dev, &dev_attr_lnext); + err |= device_create_file(&rdev->dev, &dev_attr_hopcount); if (!err && rdev->rswitch->sw_sysfs) err = rdev->rswitch->sw_sysfs(rdev, RIO_SW_SYSFS_CREATE); } @@ -241,6 +276,8 @@ void rio_remove_sysfs_dev_files(struct r device_remove_bin_file(&rdev->dev, &rio_config_attr); if (rdev->pef & RIO_PEF_SWITCH) { device_remove_file(&rdev->dev, &dev_attr_routes); + device_remove_file(&rdev->dev, &dev_attr_lnext); + device_remove_file(&rdev->dev, &dev_attr_hopcount); if (rdev->rswitch->sw_sysfs) rdev->rswitch->sw_sysfs(rdev, RIO_SW_SYSFS_REMOVE); } _ Patches currently in -mm which might be from alexandre.bounine@xxxxxxx are rapidio-use-common-destid-storage-for-endpoints-and-switches.patch rapidio-integrate-rio_switch-into-rio_dev.patch rapidio-add-definitions-of-component-tag-fields.patch rapidio-add-device-object-linking-into-discovery.patch rapidio-use-component-tag-for-unified-switch-identification.patch rapidio-add-new-sysfs-attributes.patch rapidio-add-new-idt-srio-switches.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
