- s-Par Proc Entries
-This document describes the proc entries created by the Unisys s-Par modules.
-
-Support Module Entries
-These entries are provided primarily for debugging.
-
-/proc/uislib/info: This entry contains debugging information for the
-uislib module, including bus information and memory usage.
-
-/proc/visorchipset/controlvm: This directory contains debugging
-entries for the controlvm channel used by visorchipset.
-
-/proc/uislib/platform: This entry is used to display the platform
-number this node is in the system. For some guests, this may be
-invalid.
-
-/proc/visorchipset/chipsetready: This entry is written to by scripts
-to signify that any user level activity has been completed before the
-guest can be considered running and is shown as running in the s-Par
-UI.
-
-Device Entries
-These entries provide status of the devices shared by a service partition.
-
-/proc/uislib/vbus: this is a directory containing entries for each
-virtual bus. Each numbered sub-directory contains an info entry, which
-describes the devices that appear on that bus.
-
-/proc/uislib/cycles_before_wait: This entry is used to tune
-performance, by setting the number of cycles we wait before going idle
-when in polling mode. A longer time will reduce message latency but
-spend more processing time polling.
-
-/proc/uislib/smart_wakeup: This entry is used to tune performance, by
-enabling or disabling smart wakeup.
-
-/proc/virthba/info: This entry contains debugging information for the
-virthba module, including interrupt information and memory usage.
-
-/proc/virthba/enable_ints: This entry controls interrupt use by the
-virthba module. Writing a 0 to this entry will disable interrupts.
-
-/proc/virtnic/info: This entry contains debugging information for the
-virtnic module, including interrupt information, send and receive
-counts, and other device information.
-
-/proc/virtnic/ethX: This is a directory containing entries for each
-virtual NIC. Each named subdirectory contains two entries,
-clientstring and zone.
-
-/proc/virtpci/info: This entry contains debugging information for the
-virtpci module, including virtual PCI bus information and device
-locations.
-
-/proc/virtnic/enable_ints: This entry controls interrupt use by the
-virtnic module. Writing a 0 to this entry will disable interrupts.
-
-Visorconinclient, visordiag, visornoop, visorserialclient, and
-visorvideoclient Entries
-
-The entries in proc for these modules all follow the same
-pattern. Each module has its own proc directory with the same name,
-e.g. visordiag presents a /proc/visordiag directory. Inside of the
-module's directory are a device directory, which contains one numbered
-directory for each device provided by that module. Each device has a
-diag entry that presents the device number and visorbus name for that
-device. The module directory also has a driver/diag entry, which
-reports the corresponding s-Par version number of the driver.
-
-Automated Installation Entries
-
-These entries are used to pass information between the s-Par platform
-and the Linux-based installation and recovery tool. These values are
-read/write, however, the guest can only reset them to 0, or report an
-error status through the installer entry. The values are only set via
-s-Par's firmware interface, to help prevent accidentally booting into
-the tool.
-
-/proc/visorchipset/boottotool: This entry instructs s-Par that the
-next reboot will launch the installation and recovery tool. If set to
-0, the next boot will happen according to the UEFI boot manager
-settings.
-
-/proc/visorchipset/toolaction: This entry indicates the installation
-and recovery tool mode requested for the next boot.
-
-/proc/visorchipset/installer: this entry is used by the installation
-and recovery tool to pass status and result information back to the
-s-Par firmware.
-
-/proc/visorchipset/partition: This directory contains the guest
-partition configuration data for each virtual bus, for use during
-installation and at runtime for s-Par service partitions.
