2020-09-09Move QOM typedefs and add missing includesEduardo Habkost1-2/+4
Some typedefs and macros are defined after the type check macros. This makes it difficult to automatically replace their definitions with OBJECT_DECLARE_TYPE. Patch generated using: $ ./scripts/codeconverter/converter.py -i \ --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]') which will split "typdef struct { ... } TypedefName" declarations. Followed by: $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \ $(git grep -l '' -- '*.[ch]') which will: - move the typedefs and #defines above the type check macros - add missing #include "qom/object.h" lines if necessary Reviewed-by: Daniel P.

2019-08-16Include migration/vmstate.h lessMarkus Armbruster1-0/+1
In my "build everything" tree, changing migration/vmstate.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). hw/hw.h supposedly includes it for convenience. Several other headers include it just to get VMStateDescription. The previous commit made that unnecessary. Include migration/vmstate.h only where it's still needed. Touching it now recompiles only some 1600 objects.

2016-02-26ARM: PL061: Checking register r/w accesses to reserved areaWei Huang1-8/+22
pl061.c emulates two GPIO devices, ARM PL061 and TI Stellaris, which share the same read/write functions (pl061_read and pl061_write). However PL061 and Stellaris have different GPIO register definitions and pl061_read()/pl061_write() doesn't check it. This patch enforces checking on offset, preventing R/W into the reserved memory area.

This patch removes the float_high field of PL061State, which doesn't seem to be used anywhere. Because this changes the device state, the version ID is also bumped up for the reason of compatiblity.

2016-02-18ARM: PL061: Clear PL061 device state after resetWei Huang1-4/+27
Current QEMU doesn't clear PL061 state after reset. This causes a weird issue with guest reboot via GPIO. Here is the device state with two reboot requests: (PL061State fields) data old_in_data istate VM boot 0 0 0 After 1st ACPI reboot request 8 8 8 After VM PL061 driver ACK 8 8 0 After VM reboot 8 8 0 ------------------------------------------------------------ 2nd ACPI reboot request 8 In the second reboot request above, because the old_in_data field is 8, QEMU decides that there is a pending edge IRQ already (see pl061_update()) in input; so it doesn't raise up IRQ again. As a result the second reboot request is lost. The correct way is to clear PL061 device state after reset. The default reset state is found from the documents listed below. Per Peter's suggestion that QEMU automatically calls reset function after device initialization, this patch removes calling pl061_reset() from pl061_initfn().

2014-09-12pl061: implement input interrupt logicColin Leitner1-14/+45
This patch adds the missing input interrupt logic to the pl061 GPIO device. To keep the floating output pins to stay high, the old state variable had to be split into two separate ones for input and output - which brings the vmstate version to 3. Edge level interrupts and I/O were tested under Linux 3.14. Level interrupt handling hasn't been tested.
