- save and restore the PCI configuration registers
#include <sys/ddi.h> #include <sys/sunddi.h> int pci_save_config_regs(dev_info_t *dip);
int pci_restore_config_regs(dev_info_t *dip);
Solaris DDI-specific (Solaris DDI).
Pointer to the device's dev_info structure.
pci_save_config_regs() saves the current configuration registers on persistent system memory. pci_restore_config_regs() restores configuration registers previously saved by pci_save_config_regs().
pci_save_config_regs() should be called by the driver's power() entry point before powering a device off (to PCI state D3). Likewise, pci_restore_config_regs() should be called after powering a device on (from PCI state D3), but before accessing the device. See power(9E).
pci_save_config_regs() and pci_restore_config_regs() return:
Operation completed successfully.
Operation failed to complete successfully.
Both these functions can be called from user or kernel context.
Example 1 Invoking the save and restore functions
static int xx_power(dev_info_t *dip, int component, int level) { struct xx *xx; int rval = DDI_SUCCESS; xx = ddi_get_soft_state(xx_softstate, ddi_get_instance(dip)); if (xx == NULL) { return (DDI_FAILURE); } mutex_enter(&xx->x_mutex); switch (level) { case PM_LEVEL_D0: XX_POWER_ON(xx); if (pci_restore_config_regs(dip) == DDI_FAILURE) { /* * appropriate error path handling here */ ... rval = DDI_FAILURE; } break; case PM_LEVEL_D3: if (pci_save_config_regs(dip) == DDI_FAILURE) { /* * appropriate error path handling here */ ... rval = DDI_FAILURE; } else { XX_POWER_OFF(xx); } break; default: rval = DDI_FAILURE; break; } mutex_exit(&xx->x_mutex); return (rval); }
