The other + * fields are set up by XPC. (xpc_rsvd_page points to the local + * partition's reserved page.) + * + * part_nasids mask + * mach_nasids mask + * + * SAL also sets up two bitmaps (or masks), one that reflects the actual + * nasids in this partition (part_nasids), and the other that reflects + * the actual nasids in the entire machine (mach_nasids). We're only + * interested in the even numbered nasids (which contain the processors + * and/or memory), so we only need half as many bits to represent the + * nasids. The part_nasids mask is located starting at the first cacheline + * following the reserved page header. The mach_nasids mask follows right + * after the part_nasids mask.

This module is made up of two parts: + * + * partition This part detects the presence/absence of other + * partitions. It provides a heartbeat and monitors + * the heartbeats of other partitions. + * + * channel This part manages the channels and sends/receives + * messages across them to/from other partitions. + * + * There are a couple of additional functions residing in XP, which + * provide an interface to XPC for its users. + * + * + * Caveats: + * + * . We currently have no way to determine which nasid an IPI came + * from. Thus, xpc_IPI_send() does a remote AMO write followed by + * an IPI. The AMO indicates where data is to be pulled from, so + * after the IPI arrives, the remote partition checks the AMO word. + * The IPI can actually arrive before the AMO however, so other code + * must periodically check for this case. Also, remote AMO operations + * do not reliably time out. Thus we do a remote PIO read solely to + * know whether the remote partition is down and whether we should + * stop sending IPIs to it. This remote PIO read operation is set up + * in a special nofault region so SAL knows to ignore (and cleanup) + * any errors due to the remote AMO write, PIO read, and/or PIO + * write operations. + * + * If/when new hardware solves this IPI problem, we should abandon + * the current approach. + * + */ + +#include <linux/kernel.h> +#include <linux/module.h> +#include <linux/init.h> +#include <linux/cache.h> +#include <linux/interrupt.h> +#include <linux/delay.h> +#include <linux/reboot.h> +#include <linux/completion.h> +#include <linux/kdebug.h> +#include <linux/kthread.h> +#include <linux/uaccess.h> +#include <asm/sn/intr.h> +#include <asm/sn/sn_sal.h> +#include "xpc.h" + +/* define two XPC debug device structures to be used with dev_dbg() et al */ + +struct device_driver xpc_dbg_name = { + .name = "xpc" +}; + +struct device xpc_part_dbg_subname = { + .bus_id = {0}, /* set to "part" at xpc_init() time */ + .driver = &xpc_dbg_name +}; + +struct device xpc_chan_dbg_subname = { + .bus_id = {0}, /* set to "chan" at xpc_init() time */ + .driver = &xpc_dbg_name +}; + +struct device *xpc_part = &xpc_part_dbg_subname; +struct device *xpc_chan = &xpc_chan_dbg_subname; + +static int xpc_kdebug_ignore; + +/* systune related variables for /proc/sys directories */ + +static int xpc_hb_interval = XPC_HB_DEFAULT_INTERVAL; +static int xpc_hb_min_interval = 1; +static int xpc_hb_max_interval = 10; + +static int xpc_hb_check_interval = XPC_HB_CHECK_DEFAULT_INTERVAL; +static int xpc_hb_check_min_interval = 10; +static int xpc_hb_check_max_interval = 120; + +int xpc_disengage_request_timelimit = XPC_DISENGAGE_REQUEST_DEFAULT_TIMELIMIT; +static int xpc_disengage_request_min_timelimit; /* = 0 */ +static int xpc_disengage_request_max_timelimit = 120; + +static ctl_table xpc_sys_xpc_hb_dir[] = { + { + .ctl_name = CTL_UNNUMBERED, + .procname = "hb_interval", + .data = &xpc_hb_interval, + .maxlen = sizeof(int), + .mode = 0644, + .proc_handler = &proc_dointvec_minmax, + .strategy = &sysctl_intvec, + .extra1 = &xpc_hb_min_interval, + .extra2 = &xpc_hb_max_interval}, + { + .ctl_name = CTL_UNNUMBERED, + .procname = "hb_check_interval", + .data = &xpc_hb_check_interval, + .maxlen = sizeof(int), + .mode = 0644, + .proc_handler = &proc_dointvec_minmax, + .strategy = &sysctl_intvec, + .extra1 = &xpc_hb_check_min_interval, + .extra2 = &xpc_hb_check_max_interval}, + {} +}; +static ctl_table xpc_sys_xpc_dir[] = { + { + .ctl_name = CTL_UNNUMBERED, + .procname = "hb", + .mode = 0555, + .child = xpc_sys_xpc_hb_dir}, + { + .ctl_name = CTL_UNNUMBERED, + .procname = "disengage_request_timelimit", + .data = &xpc_disengage_request_timelimit, + .maxlen = sizeof(int), + .mode = 0644, + .proc_handler = &proc_dointvec_minmax, + .strategy = &sysctl_intvec, + .extra1 = &xpc_disengage_request_min_timelimit, + .extra2 = &xpc_disengage_request_max_timelimit}, + {} +}; +static ctl_table xpc_sys_dir[] = { + { + .ctl_name = CTL_UNNUMBERED, + .procname = "xpc", + .mode = 0555, + .child = xpc_sys_xpc_dir}, + {} +}; +static struct ctl_table_header *xpc_sysctl; + +/* non-zero if any remote partition disengage request was timed out */ +int xpc_disengage_request_timedout; + +/* #of IRQs received */ +static atomic_t xpc_act_IRQ_rcvd; + +/* IRQ handler notifies this wait queue on receipt of an IRQ */ +static DECLARE_WAIT_QUEUE_HEAD(xpc_act_IRQ_wq); + +static unsigned long xpc_hb_check_timeout; + +/* notification that the xpc_hb_checker thread has exited */ +static DECLARE_COMPLETION(xpc_hb_checker_exited); + +/* notification that the xpc_discovery thread has exited */ +static DECLARE_COMPLETION(xpc_discovery_exited); + +static struct timer_list xpc_hb_timer; + +static void xpc_kthread_waitmsgs(struct xpc_partition *, struct xpc_channel *); + +static int xpc_system_reboot(struct notifier_block *, unsigned long, void *); +static struct notifier_block xpc_reboot_notifier = { + .notifier_call = xpc_system_reboot, +}; + +static int xpc_system_die(struct notifier_block *, unsigned long, void *); +static struct notifier_block xpc_die_notifier = { + .notifier_call = xpc_system_die, +}; + +/* + * Timer function to enforce the timelimit on the partition disengage request. + */ +static void +xpc_timeout_partition_disengage_request(unsigned long data) +{ + struct xpc_partition *part = (struct xpc_partition *)data; + + DBUG_ON(time_before(jiffies, part->disengage_request_timeout)); + + (void)xpc_partition_disengaged(part); + + DBUG_ON(part->disengage_request_timeout != 0); + DBUG_ON(xpc_partition_engaged(1UL << XPC_PARTID(part)) != 0); +} + +/* + * Notify the heartbeat check thread that an IRQ has been received. + */ +static irqreturn_t +xpc_act_IRQ_handler(int irq, void *dev_id) +{ + atomic_inc(&xpc_act_IRQ_rcvd); + wake_up_interruptible(&xpc_act_IRQ_wq); + return IRQ_HANDLED; +} + +/* + * Timer to produce the heartbeat.
