Interface Level

Solaris DDI Specific (Solaris DDI)

Parameters

handle

The access handle returned from csx_RequestIO(9F), csx_RequestWindow(9F), or csx_DupHandle(9F).

hostaddr

Source host address.

offset

The offset in bytes from the base of the mapped resource.

repcount

Number of data accesses to perform.

flags

Device address flags.

Description

These functions generate multiple writes of various sizes to the mapped memory or device register.

The csx_RepPut8(), csx_RepPut16(), csx_RepPut32(), and csx_RepPut64() functions generate repcount writes of 8 bits, 16 bits, 32 bits, and 64 bits of data, respectively, to the device address represented by the handle, handle, at an offset in bytes represented by the offset, offset. The data written is read consecutively from the buffer pointed to by the host address pointer, hostaddr.

Data that consists of more than one byte will automatically be translated to maintain a consistent view between the host and the device based on the encoded information in the data access handle. The translation may involve byte swapping if the host and the device have incompatible endian characteristics.

When the flags argument is set to CS_DEV_AUTOINCR, these functions increment the device offset, offset, after each datum write operation. However, when the flags argument is set to CS_DEV_NO_AUTOINCR, the same device offset will be used for every datum access. For example, this flag may be useful when writing to a data register.

Context

These functions may be called from user, kernel, or interrupt context.
