*
* SYSTEM SPECIFICATION FILE
*
*
* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
*
* It is not recommended to edit this file directly but rather
* to deliver configuration fragments into files under /etc/system.d;
* files in /etc/system.d are combined in alphabetical order and read by
* the kernel before this file (/etc/system) is processed.
*
* Refer to the system(4) manual page for more information and
* recommendations on naming fragment files.
*
* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
*
* As SmartOS ships with /etc/ off a ramdisk, we don't support using the
* /etc/system.d mechanism.
*
* moddir:
*
* Set the search path for modules. This has a format similar to the
* csh path variable. If the module isn't found in the first directory
* it tries the second and so on. The default is /kernel /usr/kernel
*
* Example:
* moddir: /kernel /usr/kernel /other/modules
* root device and root filesystem configuration:
*
* The following may be used to override the defaults provided by
* the boot program:
*
* rootfs: Set the filesystem type of the root.
*
* rootdev: Set the root device. This should be a fully
* expanded physical pathname. The default is the
* physical pathname of the device where the boot
* program resides. The physical pathname is
* highly platform and configuration dependent.
*
* Example:
* rootfs:ufs
* rootdev:/sbus@1,f8000000/esp@0,800000/sd@3,0:a
*
* (Swap device configuration should be specified in /etc/vfstab.)
* exclude:
*
* Modules appearing in the moddir path which are NOT to be loaded,
* even if referenced. Note that `exclude' accepts either a module name,
* or a filename which includes the directory.
*
* Examples:
* exclude: win
* exclude: sys/shmsys
* forceload:
*
* Cause these modules to be loaded at boot time, (just before mounting
* the root filesystem) rather than at first reference. Note that
* forceload expects a filename which includes the directory. Also
* note that loading a module does not necessarily imply that it will
* be installed.
*
* Example:
* forceload: drv/foo
* set:
*
* Set an integer variable in the kernel or a module to a new value.
* This facility should be used with caution. See system(4).
*
* Examples:
*
* To set variables in 'unix':
*
* set nautopush=32
* set maxusers=40
*
* To set a variable named 'debug' in the module named 'test_module'
*
* set test_module:debug = 0x13
set ibft_noprobe=1
set noexec_user_stack=1
set noexec_user_stack_log=1
set rlim_fd_cur=65536
* Ensure that c-states are disabled
set idle_cpu_no_deep_c=1
* 10 GbE Tuning
set ip:ip_squeue_fanout=1
*
* Machines should take a crash dump and reboot when receiving an NMI
*
set pcplusmp:apic_panic_on_nmi=1
set apix:apic_panic_on_nmi=1
*
* Don't use multi-threaded fast crash dump or a high compression level
*
set dump_plat_mincpu=0
set dump_bzip2_level=1
*
* Want additional crash dump metrics
*
set dump_metrics_on=1
*
* The traditional (and essentially entirely brain dead) cfgadm(1M)-centric
* model of hotpluggin' appears to be basically unnecessary. This tunable
* enables the system to create device nodes for newly inserted devices
* automatically. See: usr/src/uts/common/io/sata/impl/sata.c:97
*
set sata:sata_auto_online=1
*
* We want to limit the time spent in any one I/O to 10 seconds for targets
* that are not optical. This is still a very long time; our queue depth is
* typically 10 or less, and disks will usually fail a command after 2-3s.
* So we'd have to have multiple reads of bad sectors queued up to have any
* chance of timing out. In practice, timeouts occur because of problems with
* disk controllers or firmware, not media errors, and in those cases it will
* not help at all to wait longer.
*
set sd:sd_io_time=10
* Use hires tick to improve some scheduling latency issues
set hires_tick=1
