sdi_mca_conf(D3sdi)

sdi_mca_conf -- interpret MCA HBA driver information and store in resource manager database

Synopsis

   #include <sys/sdi.h>

   void sdi_mca_conf(HBA_IDATA_STRUCT *idata, int cntls,
   	int (*drv_mca_conf)());

Description

sdi_mca_conf is used by MCA HBA drivers to derive and store device parameters into the resource manager database. sdi_mca_conf calls the function drv_mca_conf to obtain the device parameters (typically drv_mca_conf derives the parameters by interpreting MCA POS registers which it accesses using cm_read_devconfig(D3) and cm_write_devconfig(D3)). sdi_mca_conf should be called by all autoconfig capable MCA HBA drivers during initialization or loading.

Arguments

idata: Pointer to array of idata structures (one for each controller controlled by the calling MCA HBA driver).
cntls: Number of controllers. This should represent the size of the idata structure array.
drv_mca_conf: Function called to interpret MCA POS registers. It should take three arguments: an HBA_IDATA_STRUCT for a particular controller, an integer pointer to store the I/O address range length, and an integer pointer to store the memory address range length. It should populate the HBA_IDATA_STRUCT appropriately and appropriately store the I/O and memory lengths.

Return values

None

Usage

Context and synchronization

Blockable context.

Driver-defined basic locks, read/write locks, and sleep locks can be held across calls to this function.

Applicable hardware

x86/Pentium compatible architectures

Version applicability

sdi: 2, 3, 4 HBA drivers.
