+.TH HSAVMCORE 8 "May 2021" "s390-tools"
+.
+.SH NAME
+hsavmcore - Enable kdump to release the HSA memory early in the dump process
+.
+.SH SYNOPSIS
+.B hsavmcore
+.RI [ OPTIONS ]
+.
+.SH DESCRIPTION
+.B hsavmcore
+is designed to make the dump process with kdump more efficient.
+The HSA memory contains a part of the production kernel's memory.
+Use hsavmcore to cache this information and release HSA memory early in the process.
+.PP
+Depending on the size of the production kernel's memory, writing the dump to persistent
+storage can be time consuming and prevent the HSA memory from being reused by other LPARs.
+.
+The
+.B hsavmcore
+tool performs these steps:
+.IP "  1)"
+Read the size of the HSA memory from
+.B /sys/kernel/debug/zcore/hsa.
+.IP "  2)"
+Cache the HSA memory content contained in
+.B /proc/vmcore
+either in regular memory or within the file system.
+.IP "  3)"
+Releases the HSA memory by writing to
+.B /sys/kernel/debug/zcore/hsa.
+.PP
+At this stage, the HSA memory region is unavailable to
+.B /proc/vmcore
+and cannot be used by kdump.
+.
+The
+.B hsavmcore
+tool now combines the cached HSA memory and the non-HSA memory from the original
+.B /proc/vmcore
+to create a replacement for
+.B /proc/vmcore.
+.
+The replacement
+.B /proc/vmcore
+can be processed as usual.

+.TH HSAVMCORE.CONF 5 "May 2021" "s390-tools"
+.SH NAME
+hsavmcore.conf \- Configuration file for the hsavmcore tool
+.
+.SH DESCRIPTION
+The
+.B hsavmcore.conf
+configuration file contains the configuration information for
+the
+.B hsavmcore
+tool.
+
+All specifications in the configuration file are optional.
+The command defaults apply for omitted parameters.
+.
+.SS "verbose"
+This parameter sets the verbosity level of the output messages.
+The following pre-defined numeric values can be used:
+.
+.RS 2
+.IP "-" 2
+\fB0\fP - show only error messages (default)
+.IP "-" 2
+\fB1\fP - show error and warning messages
+.IP "-" 2
+\fB2\fP - show error, warning and information messages
+.IP "-" 2
+\fB3\fP - show error, warning, information and debug messages
+.IP "-" 2
+\fB4\fP - show error, warning, information, debug and trace messages
+.RE
+.PP
+.
+.SS "mount_debugfs"
+Mount (1) or do not mount (0) debugfs. Use this configuration if the kdump kernel
+does not mount the debugfs during the boot process.
+.
+.SS "workdir"
+Specifies a work directory on the kdump system where the hsavmcore tool can create
+temporary files. This specification is required if
+.B use_hsa_mem
+is set to 0.
+.
+.SS "use_hsa_mem"
+Cache the HSA memory in regular memory (1) or in a file on a file system (0).
+.
+.SS "hsa_size"
+Specify a value, in bytes, for the HSA memory size instead of reading the size
+from
+.B /sys/kernel/debug/zcore/hsa.
+This parameter is intended only to test
+the
+.B hsavmcore
+tool without being in a kdump kernel. Specifying -1 falls back
+to reading the size from
+.B /sys/kernel/debug/zcore/hsa.
+.
+.SS "release_hsa"
+Release (1) or do not release (0) the HSA memory after it is cached by
+the
+.B hsavmcore
+tool.
+.
+.SS "bind_mount_vmcore"
+Replace (1) the original vmcore file with the new file created by the
+.B hsavmcore
+tool or keep the original file (0), which no longer contains the information
+from the HSA memory. Set this parameter to 1 if you intend to use kdump tools to
+create a core dump.
+.
+.SS "swap"
+Specify a swap device or file through its path in a kdump system.
+The specified swap device or file must exist and have the proper swap format.
+You might need a swap device because the amount of memory available in the kdump
+kernel during a stand-alone dump is limited to the size of the HSA memory.
+.
+.SS "fuse_debug"
+Enable (1) or disable (0) fuse debugging.
+.
+.SH EXAMPLES
+A complete configuration file could look like this:
+
