2012-10-12hw/ds1338: Implement state save/restorePeter Maydell1-5/+22
Implement state save/restore for the DS1338. This requires the usual minor adjustment of types in the state struct to get fixed-width ones with vmstate macros. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-12hw/ds1338: Remove 'now' field from state structPeter Maydell1-20/+21
The 'struct tm now' field in the state structure is in fact only ever used as a temporary (the actual RTC state is held in 'offset'). Remove it from the state structure in favour of using local variables to avoid confusion about whether it needs to be saved on migration. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-12hw/ds1338: Recapture current time when register pointer wraps aroundPeter Maydell1-17/+42
The DS1338 datasheet documents that the current time is captured into the secondary registers when the register pointer wraps round to zero as well as at a START condition. Implement this. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-12hw/ds1338: Fix mishandling of register pointerPeter Maydell1-7/+13
Correct several deficiencies in the handling of the register pointer: * it should wrap around after 0x3f, not 0xff * guard against the caller handing us an out of range pointer (on h/w this can never happen, because only a 7 bit value is transferred over the I2C bus) * there was confusion over whether nvram[] holds only the 56 bytes of guest-accessible NVRAM, or also the secondary registers which hold the value of the clock captured at the start of a multibyte read. Correct to consistently be the latter, by fixing the array size and the offset used for NVRAM writes. * ds1338_send was attempting to use 'data' as both the data and the register offset simultaneously, which meant that writes to any register were broken; fix to use the register pointer.

2012-03-19ds1338: Add missing break statementStefan Weil1-0/+1
Without the break statement, case 5 sets month and year from the same data. This does not look correct. The missing break was reported by splint.

2012-02-15qom: Unify type registrationAndreas Färber1-2/+2
Replace device_init() with generalized type_init(). While at it, unify naming convention: type_init([$prefix_]register_types) Also, type_init() is a function, so add preceding blank line where necessary and don't put a semicolon after the closing brace.

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori1-5/+6
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-27i2c: smbus: convert to QEMU Object ModelAnthony Liguori1-7/+14
This converts two types because smbus is implemented as a subclass of i2c. It's extremely difficult to convert these two independently. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
