◆ MAX_BOOT_TIME_PTP270PEX

#define MAX_BOOT_TIME_PTP270PEX 27

Max. time required for PTP270PEX v1 card to be ready after power-up.

The PTP270PEX cards have an on-board Linux system which must have finished booting before the card can be accessed via the PCI bus. If the card is accessed earlier then the PCI bus and thus the computer may hang.

There are 2 different hardware versions of the PTP270PEX card. PTP270PEX v2 hardware and firmware can flag via a bit in the PCI configuration space when the card is ready, so the driver can just wait until the card has flagged that it's ready.

However, the PTP270PEX v1 hardware doesn't support this, so the driver checks the system uptime and waits until it is greater or equal the maximum time required for a PTP270PEX v1 card to finish booting.

The nominal time is 27 s, but if a firmware update has been submitted then the update is applied first, which takes another few seconds.

◆ ptp270pex_can_flag_ready()

static bool ptp270pex_can_flag_ready ( const PCPS_DDEV * pddev )

static

Check if a PTP270PEX card can indicate when it's ready.

A PTP270PEX card must be accessed by the driver only after it has finished booting. Otherwise the host system may be locked up.

On HW v2 cards the firmware can indicate when the card is ready to be accessed, so this can be checked by the driver. On these cards the on-board GPIO3 pin is hardwired to 0 to indicate this is supported, whereas on older v1 cards the GPIO3 pin is pulled up to 1.

Parameters

[in] pddev Pointer to the device structure

Returns: true if the card can flag "ready"

◆ ptp270pex_has_flagged_ready()

static bool ptp270pex_has_flagged_ready ( const PCPS_DDEV * pddev )

static

Check if a PTP270PEX card indicates it is ready.

A PTP270PEX card must be accessed by the driver only after it has finished booting. Otherwise the host system may be locked up.

On HW v2 cards the firmware can indicate when the card is ready to be accessed, so the driver can call this function to check this.

Note: The function ptp270pex_can_flag_ready should have been called before to check if the card actually supports this.

Parameters

[in] pddev Pointer to the device structure

Returns: true if the card has flagged "ready"

◆ pc_cycles_frequency

MBG_PC_CYCLES_FREQUENCY pc_cycles_frequency

static

Clock frequency of the PC's cycles counter, in [Hz].

An attempt to determine this value is made at the beginning of the pcps_probe_device routine. If the cycles frequency value is 0 then the target system doesn't supported this, or the value couldn't be determined. In this case it's not possible to convert a number of cycles to an associatred time interval.

◆ ri_feat_tbl

uint32_t ri_feat_tbl[N_GPS_FEATURE]

static

A table used to map RECEIVER_INFO::features to PCPS_DEV_CFG::features.

The enumerated GPS_FEATURE_BITS can be used as index to this table, and the table entry contains a combination of associated PCPS_FEATURE_MASKS, if there are any.

Note: Devices which support a configurable time scale do also support reading/writing the GPS UTC parameters via the PC bus. This is not explicitly coded in the RECEIVER_INFO::features since the the RECEIVER_INFO structure can also be read via the serial port, and reading/writing the GPS UTC parameters via the serial port is supported by all GPS devices anyway.; Devices which support reading MBG_RAW_IRIG_DATA via the PC bus interface also support reading PCPS_IRIG_TIME. However, there is no associated flag in RECEIVER_INFO::features since this call is not supported via the serial interface. Thus we use the GPS_HAS_RAW_IRIG_DATA flag to check both features.
