2011-10-10isa: Tidy support code for isabus_get_fw_dev_pathRichard Henderson
The only user of ISADevice.ioports is isabus_get_fw_dev_path, and it only looks at the first entry of the array. Which suggests that this entire array+sort operation can be replaced by a simple minimum. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25isa: add isa_register_ioport()Richard Henderson
To replace isa_init_ioport and isa_init_ioport_range as the ISA devices are converted to the memory api. [avi: use memory_region_size()] Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25isa: Pass i/o address space to isa_bus_newRichard Henderson
Not used yet, but at least we're provided with the correct region. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-08-22isa: add isa_address_space()Avi Kivity
A helper that returns the address space used by ISA devices. Useful for getting rid of isa_mem_base, multiple ISA buses, or ISA buses behind bridges. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-02-21isa-bus: Remove bogus IRQ sharing checkJan Kiszka
Nothing prevented IRQ sharing on the ISA bus in principle. Not all boards supported this, neither each and every card nor driver and OS. Still, there existed valid IRQ sharing scenarios, (at least) two of them can also be found in QEMU: >2 PC UARTs and the PREP IDE buses. So remove this artificial restriction from our ISA model.

2010-12-11Introduce fw_name field to DeviceInfo structure.Gleb Natapov
Add "fw_name" to DeviceInfo to use in device path building. In contrast to "name" "fw_name" should refer to functionality device provides instead of particular device model like "name" does. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-12-11isa-bus.c: use hw_error instead of fprintfTristan Gingold
Minor clean-up in isa-bus.c. Using hw_error is more consistent. There is a difference however: hw_error dumps the cpu state. Signed-off-by: Tristan Gingold <gingold@adacore.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-10-07Make isa_create() terminate program on failureMarkus Armbruster
Callers don't check the return value anyway. Patchworks-ID: 35172 Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-07New qdev_init_nofail()Markus Armbruster
Like qdev_init(), but terminate program via hw_error() instead of returning an error value. Use it instead of qdev_init() where terminating the program on failure is okay, either because it's during machine construction, or because we know that failure can't happen. Because relying in the latter is somewhat unclean, and the former is not always obvious, it would be nice to go back to qdev_init() in the not-so-obvious cases, only with proper error handling. I'm leaving that for another day, because it involves making sure that error values are properly checked by all callers.

2009-10-07Make qdev_init() destroy the device on failureMarkus Armbruster
Before, every caller had to do this. Only two actually did. Patchworks-ID: 35170 Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
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: tag isabus-bridge as no-userGerd Hoffmann
isabus-bridge isn't supposed to be added via -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.
