Hi all. I was able to set up an IBM Ultrium LTO 4 tape drive to use iSCSI (using open-iscsi drivers) to communicate with Red Hat, but it's going really slow, maxing out in tar and dd tests at like 16 MB/s (using a block size of 128k). The thing is rated for 30MB/s. I feel like even though I have... (1 Reply)

acpi_toshiba
ACPI_TOSHIBA(4) BSD/i386 Kernel Interfaces Manual ACPI_TOSHIBA(4)
NAME
acpi_toshiba -- Toshiba HCI interface
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device acpi_toshiba
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
acpi_toshiba_load="YES"
DESCRIPTION
HCI is Toshiba's Hardware Control Interface which is somewhat uniform across their models. The acpi_toshiba driver allows the user to manip-
ulate HCI-controlled hardware using a number of sysctl(8) variables.
SYSCTL VARIABLES
The following sysctls are currently implemented:
hw.acpi.toshiba.force_fan
Causes active cooling to be forcibly enabled ('1') or disabled ('0') regardless of the current temperature.
hw.acpi.toshiba.video_output
Sets the active display to use according to a bitwise OR of the following:
0 No display
1 LCD
2 CRT
4 TV-Out
Only some systems (i.e., the Libretto L5) support video switching via this hardware-specific driver. Use the acpi_video(4) driver
for generic video output support.
hw.acpi.toshiba.lcd_brightness
Makes the LCD backlight brighter or dimmer (higher values are brighter).
hw.acpi.toshiba.lcd_backlight
Turns the LCD backlight on and off.
hw.acpi.toshiba.cpu_speed
Sets the CPU speed to the specified speed. This provides functionality similar to the hw.acpi.cpu.throttle_state variable. Higher
sysctl values mean lower CPU speeds.
Defaults for these variables can be set in sysctl.conf(5), which is parsed at boot-time.
LOADER TUNABLES
The hw.acpi.toshiba.enable_fn_keys tunable enables or disables the function keys on the keyboard. Function keys are enabled by default.
This behaviour can be changed at the loader(8) prompt or in loader.conf(5).

HISTORY
The acpi_toshiba driver first appeared in FreeBSD 5.1.

The acpi_toshiba driver was written by Hiroyuki Aizu <aizu@navi.org>. This manual page was written by Philip Paeps <philip@FreeBSD.org>.
