| H A D | iicbus.h | diff 181304 Mon Aug 04 19:16:00 MDT 2008 jhb Add locking to the core iicbus(4) drivers: - Add an sx lock to the iic(4) driver to serialize open(), close(), read(), and write and to protect sc_addr and sc_count in the softc. - Use cdev->si_drv1 instead of using the minor number of the cdev to lookup the softc via newbus in iic(4). - Store the device_t in the softc to avoid a similar detour via minor numbers in iic(4). - Only add at most one instance of iic(4) and iicsmb(4) to each iicbus(4) instance, and do it in the child driver. - Add a mutex to the iicbus(4) softc to synchronize the request/release bus stuff. - Use __BUS_ACCESSOR() for IICBUS_ACCESSOR() instead of rolling our own. - Add a mutex to the iicsmb(4) softc to protect softc state updated in the interrupt handler. - Remove Giant from all the smbus methods in iicsmb(4) now that all the iicbus(4) backend is locked. |
