2019-12-17hw: replace hw/i386/pc.h with a header just for the i8259Paolo Bonzini
Remove the need to include i386/pc.h to get to the i8259 functions. This is enough to remove the inclusion of hw/i386/pc.h from all non-x86 files. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-08-16Include hw/hw.h exactly where neededMarkus Armbruster
In my "build everything" tree, changing hw/hw.h triggers a recompile of some 2600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). The previous commits have left only the declaration of hw_error() in hw/hw.h. This permits dropping most of its inclusions. Touching it now recompiles less than 200 objects.

2019-08-16Include hw/irq.h a lot lessMarkus Armbruster
In my "build everything" tree, changing hw/irq.h triggers a recompile of some 5400 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 qemu_irq and.or qemu_irq_handler. Move the qemu_irq and qemu_irq_handler typedefs from hw/irq.h to qemu/typedefs.h, and then include hw/irq.h only where it's still needed. Touching it now recompiles only some 500 objects.

2017-12-21i8259: use DEBUG_IRQ_COUNT alwaysPeter Xu
It's not really scary to even enable it forever. After all it's i8259, and it's even not the kernel one. Then we can remove quite a few of lines to make it cleaner. And "info irq" will always work for it.

2016-03-22Replaced get_tick_per_sec() by NANOSECONDS_PER_SECONDRutuja Shah
This patch replaces get_ticks_per_sec() calls with the macro NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec() is then removed. This replacement improves the readability and understandability of code. For example, timer_mod(fdctrl->result_timer, qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50)); NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns matches the unit of the expression on the right side of the plus.

2015-02-18hmp: Name HMP info handler functions hmp_info_SUBCOMMAND()Markus Armbruster
Some are called do_info_SUBCOMMAND() (old ones, usually), some hmp_info_SUBCOMMAND(), some SUBCOMMAND_info(), sometimes SUBCOMMAND pointlessly differs in spelling. Normalize to hmp_info_SUBCOMMAND(), where SUBCOMMAND is exactly the subcommand name with '-' replaced by '_'. Exceptions: * sun4m_irq_info(), sun4m_pic_info() renamed to sun4m_hmp_info_irq(), sun4m_hmp_info_pic(). * lm32_irq_info(), lm32_pic_info() renamed to lm32_hmp_info_irq(), lm32_hmp_info_pic().

This is a guest-triggerable error, as seen when using Xenix 2.3.4. Replace hw_error by LOG_UNIMPL, so that guests can continue. With this patch, I can install and use Xenix 2.3.4a without any problem. I can also start installation of Xenix 2.3.4q, but it fails due to not finding an hard disk.
