2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

Some not so obvious bits, slirp and Xen were left alone for the time being. Signed-off-by: malc <av1474@comtv.ru>
2009-09-10qdev: add isa_create() functionGerd Hoffmann
Like isa_create_simple, but doesn't call qdev_init, so one can set properties after creating and before initializing the device. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-09-10qdev: simplify isa irq assignmentsGerd Hoffmann
isa-bus owns the isa irqs now, so it can hand them out directly. There is no need for the separate isa_connect_irqs step, drop it. Also hard-code isa interrupts which can't be configured anyway. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-09-10qdev: drop iobase properties from isa busGerd Hoffmann
Lot of ISA devices work at fixed addresses, so having iobase as bus property doesn't make much sense. Devices which can have different iobases will get a device property. Also simply hard-code stuff which can't be configured anyway. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-08-27qdev: add return value to init() callbacks.Gerd Hoffmann
Sorry folks, but it has to be. One more of these invasive qdev patches. We have a serious design bug in the qdev interface: device init callbacks can't signal failure because the init() callback has no return value. This patch fixes it. We have already one case in-tree where this is needed: Try -device virtio-blk-pci (without drive= specified) and watch qemu segfault. This patch fixes it. With usb+scsi being converted to qdev we'll get more devices where the init callback can fail for various reasons.

2009-08-27Move isa_connect_irq calls into isa_create_simpleGerd Hoffmann
Now with isa-bus maintaining the isa irqs we can move the isa_connect_irq() calls into isa_create_simple(). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-08-27Add isa_reserve_irq().Jes Sorensen
Introduce isa_reserve_irq() which marks an irq reserved and returns the appropriate qemu_irq entry from the i8259 table. isa_reserve_irq() is a temporary interface to be used to allocate ISA IRQs for devices which have not yet been converted to qdev, and for special cases which are not suited for qdev conversions, such as the 'ferr'. This patch goes on top of Gerd Hoffmann's which makes isa-bus.c own the ISA irq table.

2009-08-27isa bus irq changes and fixes.Gerd Hoffmann
Changes: (1) make isa-bus maintain isa irqs, complain when allocating already taken irqs. (2) note that (1) works only for isa devices converted to qdev already (floppy and ps2/kbd/mouse right now), so more work is needed to make this really useful. (3) split floppy init into isa and sysbus versions. (4) add sysbus->isa bridge & fix -M isapc breakage.

2008-10-31Make DMA bottom-half driven (v2)aliguori
The current DMA routines are driven by a call in main_loop_wait() after every select. This patch converts the DMA code to be driven by a constantly rescheduled bottom half. The advantage of using a scheduled bottom half is that we can stop scheduling the bottom half when there no DMA channels are runnable. This means we can potentially detect this case and sleep longer in the main loop. The only two architectures implementing DMA_run() are cris and i386. For cris, I converted it to a simple repeating bottom half. I've only compile tested this as cris does not seem to work on a 64-bit host. It should be functionally identical to the previous implementation so I expect it to work. For x86, I've made sure to only fire the DMA bottom half if there is a DMA channel that is runnable. The effect of this is that unless you're using sb16 or a floppy disk, the DMA bottom half never fires. You probably should test this malc. My own benchmarks actually show slight improvement by it's possible the change in timing could affect your demos. Since v1, I've changed the code to use a BH instead of a timer. cris at least seems to depend on faster than 10ms polling.
