2010-04-13vhost: fix features ackDavid L Stevens1-0/+8
vhost driver in qemu didn't ack features, and this happens to work because we don't really require any features. However, it's better not to rely on this.

2010-04-13sh_pci: fix memory and I/O accessAurelien Jarno1-96/+15
Since commit 8da3ff180974732fc4272cb4433fef85c1822961 ("MMIO callback interface changes"), the addresses passed to the I/O functions are an offset to the start of the area. As a consequence, there is no need to correct the address using the value of IOBR. This make possible the use of the default MMIO functions. Moreover the addresses are now remaped when the value if IOBR change. The memory area corresponds to the devices behing the PCI bus, it should not be mapped by the PCI controller. Remove the corresponding code. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-13r2d: always enable IDE and flashAurelien Jarno1-10/+8
IDE and flash are part of the R2D board, and can't be removed. Emulate them even if there is no hard-drive plugged to the IDE or if the flash content is empty.

2010-04-11pci: add API to add capability at a known offsetMichael S. Tsirkin2-4/+15
Unlike virtio, device emulations need to add pci capabilities at known offsets to match real hardware. Make this possible by adding an appropriate API. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2010-04-08smc91c111: mask register offsetLars Munch1-0/+2
this fixes the smc91c111 emulation which has been broken for gumstix and mainstone and maybe others since the "MMIO callback interface changes" 8da3ff180974732fc4272cb4433fef85c1822961 was commited. Signed-off-by: Lars Munch <lars@segv.dk> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

Commit 15e89f5916c9e82347cbd1fd416db3e348bab426 removed this setting, but it is still needed. Without this patch, e100 device drivers using interrupts don't work with qemu. See other nic emulations which also set the PCI interrupt pin. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2010-04-07eepro100: Set power management capability using pci_reserve_capabilityStefan Weil1-21/+18
pci_add_capability automatically updates PCI status and PCI capability pointer, so use it. Use pci_reserve_capability to make the new capability appear at the correct offset. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2010-04-06eepro100: Don't allow writing SCBStatusStefan Weil1-44/+5
SCBStatus is readonly, but most drivers which were derived from the old Linux eepro100.c do a word write to this address when they want to acknowledge interrupts. So we have to mask these writes here. The patch also removes old unused code for status read / write. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S.

Move ARMv7-M PC/SP initialization to the CPU reset routine. Add a board reset routine to call this. Also load values directly from ROM as images have not been copied yet. Avoid clearing the NVIC pointer on cpu reset. Signed-off-by: Paul Brook <paul@codesourcery.com>

This reverts commit f1698408f1dcb7548a21828a0b1e2b530fae3af3. PCI is always little-endian. Having a user-visible "be" property is just plain wrong.

2010-04-01virtio-net: vhost net supportMichael S. Tsirkin1-2/+69

2010-04-01virtio-pci: fill in notifier supportMichael S. Tsirkin1-0/+63
Support host/guest notifiers in virtio-pci. The last one only with kvm, that's okay because vhost relies on kvm anyway. Note on kvm usage: kvm ioeventfd API is implemented on non-kvm systems as well, this is the reason we don't need if (kvm_enabled()) around it. Signed-off-by: Michael S.
