2022-07-18hw/adc: Make adci[*] R/W in NPCM7XX ADCHao Wu1-1/+1
Our sensor test requires both reading and writing from a sensor's QOM property. So we need to make the input of ADC module R/W instead of write only for that to work.

2022-07-18hw/adc: Fix CONV bit in NPCM7XX ADC CON registerHao Wu1-1/+1
The correct bit for the CONV bit in NPCM7XX ADC is bit 13. This patch fixes that in the module, and also lower the IRQ when the guest is done handling an interrupt event from the ADC module.

2021-03-08clock: Add ClockEvent parameter to callbacksPeter Maydell1-1/+1
The Clock framework allows users to specify a callback which is called after the clock's period has been updated. Some users need to also have a callback which is called before the clock period is updated. As the first step in adding support for notifying Clock users on pre-update events, add an argument to the ClockCallback to specify what event is being notified, and add an argument to the various functions for registering a callback to specify which events are of interest to that callback. Note that the documentation update renders correct the previously incorrect claim in 'Adding a new clock' that callbacks "will be explained in a following section".

The ADC is part of NPCM7XX Module. Its behavior is controled by the ADC_CON register. It converts one of the eight analog inputs into a digital input and stores it in the ADC_DATA register when enabled. Users can alter input value by using qom-set QMP command.

2020-02-04hw/*/Makefile.objs: Move many .o files to common-objsThomas Huth1-1/+1
We have many files that apparently do not depend on the target CPU configuration, i.e. which can be put into common-obj-y instead of obj-y. This way, the code can be shared for example between qemu-system-arm and qemu-system-aarch64, or the various big and little endian variants like qemu-system-sh4 and qemu-system-sh4eb, so that we do not have to compile the code multiple times anymore.

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.

These symbols have to be added manually to the Kconfig files. Kconfig.host and hw/Kconfig were created manually.

2018-01-16maint: Fix macros with broken 'do/while(0); ' usageEric Blake1-1/+1
The point of writing a macro embedded in a 'do { ... } while (0)' loop (particularly if the macro has multiple statements or would otherwise end with an 'if' statement) is so that the macro can be used as a drop-in statement with the caller supplying the trailing ';'. Although our coding style frowns on brace-less 'if': if (cond) statement; else something else; that is the classic case where failure to use do/while(0) wrapping would cause the 'else' to pair with any embedded 'if' in the macro rather than the intended outer 'if'. But conversely, if the macro includes an embedded ';', then the same brace-less coding style would now have two statements, making the 'else' a syntax error rather than pairing with the outer 'if'. Thus, even though our coding style with required braces is not impacted, ending a macro with ';' makes our code harder to port to projects that use brace-less styles. The change should have no semantic impact. I was not able to fully compile-test all of the changes (as some of them are examples of the ugly bit-rotting debug print statements that are completely elided by default, and I didn't want to recompile with the necessary -D witnesses - cleaning those up is left as a bite-sized task for another day); I did, however, audit that for all files touched, all callers of the changed macros DID supply a trailing ';' at the callsite, and did not appear to be used as part of a brace-less conditional. Found mechanically via: $ git grep -B1 'while (0);' | grep -A1 \\\\ Signed-off-by: Eric Blake <eblake@redhat.com> Acked-by: Cornelia Huck <cohuck@redhat.com> Reviewed-by: Michael S.
