* i8257: Make device "i8257" unavailable with -deviceMarkus Armbruster2016-09-131-0/+2
| | | | | | | | | The ISA DMA controller needs to be wired up to the ISA bus by isa_bus_dma() to actually work. Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <1472660151-19517-1-git-send-email-armbru@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* portio: keep references on portioMarc-André Lureau2016-09-081-2/+4
| | | | | | | | | | | The isa_register_portio_list() function allocates ioports data/state. Let's keep the reference to this data on some owner. This isn't enough to fix leaks, but at least, ASAN stops complaining of direct leaks. Further cleanup would require calling portio_list_del/destroy().

* isa: Move DMA_transfer_handler from qemu-common.h to hw/isa/isa.hMarkus Armbruster2016-03-221-1/+1
| | | | | | | | | DMA_transfer_handler is actually an ISA thing, and as such has no business in qemu-common.h. Move it to hw/isa/isa.h, and rename it to IsaDmaTransferHandler. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* i8257: fix Terminal Count statusHervé Poussineau2016-03-071-0/+4
| | | | | | | | | | | | | | When a DMA transfer is done (ie all bytes have been transfered), the corresponding Terminal Count bit must be set in the status register. This bit is already cleared in i8257_read_cont and i8257_write_cont when required. This fixes (at least) floppy transfer in IBM 40p firmware, which checks in DMA controller if everything went fine.

* i8257: remove cpu_request_exit irqPaolo Bonzini2015-09-091-9/+4Star
| | | | | | | | | This is unused. cpu_exit now is almost exclusively an internal function to the CPU execution loop. In a few patches, we'll change the remaining occurrences to qemu_cpu_kick, making it truly internal.

* i8257: rewrite DMA_schedule to avoid hooking into the CPU loopPaolo Bonzini2015-09-091-6/+12
| | | | | | | | | | | | | | | | | The i8257 DMA controller uses an idle bottom half, which by default does not cause the main loop to exit. Therefore, the DMA_schedule function is there to ensure that the CPU relinquishes the iothread mutex to the iothread. However, this is not enough since the iothread will call aio_compute_timeout() and go to sleep again. In the iothread world, forcing execution of the idle bottom half is much simpler, and only requires a call to qemu_notify_event(). Do it, removing the need for the "cpu_request_exit" pseudo-irq. The next patch will remove it. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

| | | | | | | | | | | | | | | | | | | | | After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.
