2018-05-04mac_newworld: remove pics IRQ array and wire up macio to OpenPIC directlyMark Cave-Ayland1-0/+9
Introduce constants for the pre-defined New World IRQs to help keep things readable. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

The existing UNINState actually represents the PCI/AGP host bridge stage so rename it accordingly. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2018-04-27uninorth: move PCI host bridge bus initialisation into device realizeMark Cave-Ayland1-4/+2
Since the IO address space is fixed to use the standard system IO address space then we can also use the opportunity to remove the address_space_io parameter from pci_pmac_init() and pci_pmac_u3_init(). Note we also move the default mac99 PCI bus to the end of the initialisation list so that it becomes the default destination for any devices specified via -device without an explicit PCI bus provided.

2018-03-06heathrow: change heathrow_pic_init() to return the heathrow deviceMark Cave-Ayland1-2/+2
This enables the device to be made available during the setup of the Old World machine. In order to pass back the previous set of IRQs we temporarily introduce a new pic_irqs parameter until it can be removed. An additional benefit of this change is that it is also possible to remove the pic_mem pointer used for macio by accessing the memory region via sysbus.

Now that the ESCC device is instantiated directly via qdev, move it to within the macio device and wire up the IRQs and memory regions using the sysbus API. This enables to remove the now-obsolete escc_mem parameter to the macio_init() function.

2017-09-27ppc/ide/macio: Add missing registersBenjamin Herrenschmidt1-1/+5
The timing register exists on all variants of MacIO IDE, we just store and return its value. The interrupts register only exists on KeyLargo but it doesn't hurt to have it. The lack of this register causes MacOS X to hangs under some circumstances. Both are 32-bit only. The HW might support smaller access sizes but no known OS uses them. Because the core IDE subsystem doesn't provide us with a way to query the main (level) interrupt state, nor do we have a way to know that DBDMA issued a (edge) interrupt, we reflect both through a private pair of qirq's in order to maintain the register state.

2016-01-30macio: use the existing IDEDMA aiocb to hold the active DMA aiocbMark Cave-Ayland1-1/+0
Currently the aiocb is held within MACIOIDEState, however the IDE core code assumes that the current actvie DMA aiocb is held in aiocb in a few places, e.g. ide_bus_reset() and ide_reset(). Switch over to using IDEDMA aiocb to store the aiocb for the current active DMA request so that bus resets and restarts are handled correctly. As a consequence we can now use ide_set_inactive() rather than handling its functionality ourselves.

2014-09-08PPC: Cuda: Use cuda timer to expose tbfreq to guestAlexander Graf1-0/+2
Mac OS X calibrates a number of frequencies on bootup based on reading tb values on bootup and comparing them to via cuda timer values. The only variable we can really steer well (thanks to KVM) is the cuda frequency. So let's use that one to fake Mac OS X into believing the bus frequency is tbfreq * 4. That way Mac OS X will automatically calculate the correct timebase frequency. With this patch and the patch set I posted earlier I can successfully run Mac OS X 10.2, 10.3 and 10.4 guests with -M mac99 on TCG and KVM.

We should only start processing DMA requests when we have data to process. Hold off working through the DMA shuffling until the IDE core told us that it's ready. This is required because the guest can program the DMA engine or the IDE transfer first. Both are legal. Signed-off-by: Alexander Graf <agraf@suse.de>
