  • Page 33: Chapter 7 - Bsp Specific Features

    7.1.1 Sensors Overview The BSP contains an RPM named sensors_addons that configures the standard lm_sensor software for the Ki7 boards. To display sensors information: [root@ki7]# sensors Example on VX304x [root@ki7]# sensors acpitz-virtual-0 Adapter: Virtual device temp1: +37.0°C (crit = +106.0°C) temp2: +36.0°C (crit = +106.0°C)

  • Page 34: Sensors Values Limitations

    The Kontron BIOS, to inform the user that the temperature probe validity is not correct, return the value -56°C. So if a probe of these sensors value returns -56°C, it does not mean that the board is currently running at -56°C, but it only means that the probe value can not be reliable.

    * Kontron board cpld_wdt watchdog driver DESCRIPTION This man page describes how to use the watchdog implemented by the cpld on various Kontron boards including the VX304x, VX3035 and VM605x families. The principle of a watchdog is to automatically provoke some action after a given time passes without the watchdog being prodded by some process.

    - Kontron board gpio-cpld driver gpios DESCRIPTION This man page describes how to use the gpios implemented by the cpld on various Kontron boards including the VX304x, VX3035 and VM605x families. The cpld gpio driver provides an API using files in the /sys filesystem. Reads and writes to the files are directly handled by the driver, provoking reads and writes of hardware registers.

  • Page 55: 7.12 Vme

    This describes the kernel service calls available for VME device drivers or application development on Kontron platforms using the almavme driver for all boards equipped with Alma2e and Alma2f. Alma2f provides a highly integrated single chip solution to interface a VME64 bus with 2eSST protocol (two-edge Source-Synchroneous Transfer) and a 32-bit 66 MHz PCI Bus.
  • Page 56 BSP Specific Features Fedora 16 Release Notes In the following, functions are described from the kernel point of view, and examples show how to call them from a user application. User Space Ioctls All ioctls take a command argument, and an appropriate struct as third argument. As alma_ioctl_arg_t is a union of most of the possible struct types, it can be used as a suitable third argument for most of the ioctls.
  • Page 57 A24 SUPER USER MBLT are identify as AM that present some transfer error. For these cases please contact the Kontron support. This routine returns an identifier from 0 to 15 on success and -1 on failure. It can be called from user space with the ioctl() VMEIOCTL_PCI_CHAN_ALLOC.
  • Page 58 BSP Specific Features Fedora 16 Release Notes VMEFG_READAHEAD access is read ahead (default NO). It must be used with a BLT or MBLT channel. VMEFG_LEBE_xx defines the little/big endian conversion mode (default address coherency). VMEFG_PCIIO access is from PCI-IO to VME (default is access from PCI-MEM to VME). There is no difference between PCI-MEM and PCI-IO.

This feature is not available on Alma2f. For example: dma_arg.vmeaddr = strtoul(argv[1], NULL, 0); // VME address size = strtoul(argv[2], NULL, 0); dma_arg.dmaaddr = malloc(size);...
  • Page 61 Fedora 16 Release Notes BSP Specific Features ioctl(fd, VMEIOCTL_PHYSICAL_MEM_FREE , struct alma_phys_mem_object *phys_mem) calls alma_phys_mem_free(phys_mem). For example (taken from the almavmechan tool): mem_obj.size = ...; rc = ioctl(fd,VMEIOCTL_PHYSICAL_MEM_ALLOC,&mem_obj); printf(”0x%x\n”,mem_obj.cpu_phys_addr); mem_obj.cpu_phys_addr = ...; rc = ioctl(fd,VMEIOCTL_PHYSICAL_MEM_FREE,&mem_obj); Locking The VME bus can be explicitly locked before one or more accesses are done. It must always be paired with a free.

If active, the VME/PCI bridge does not request the VME if another VME device requests it on the same level. bus release mode is coded in bits 4..6 (ALMACFG_BUSREL_MSK). Four modes are supported: ALMACFG_BUSREL_ROR (release on request), ALMACFG_BUSREL_RWD (release when done), ALMACFG_BUSREL_ROC (release on clear) and ALMACFG_BUSREL_RNE (release never).

It is 7 structures of type struct vmepci_window.

Addresses for 2ESST dma must be aligned on 16 bytes. The 2ESST protocol also provides for a broadcast transfer, where one board can do a single write that is received simultaneously by several boards.

    This man page describes some of the facilities made available by the cPLD (complex programmable logic device) on several Kontron boards. Not all boards provide all the facilities. The cPLD is a small device that controls some low*level aspects of the board, including power up sequencing, reset, gpios, i2c buses including one for communication to the backplane, timer, watchdog, leds, and many configuration and control features.

    Power Management Fedora 16 Release Notes Chapter 9 - Power Management Introduction At the core of power management is an understanding of how to effectively optimize energy consumption of each system component. By studying the different tasks that your system performs, and configuring each component to ensure that its performance is just sufficient for the job, you can save energy, generate less heat.
