2009-12-03qdev: Use QError for 'device not found' errorLuiz Capitulino1-2/+2
Please, note that we will lose the "Try -device '?' for a list" hint as it's qdev specific. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-02fix I2C slave addressingJuha Riihimäki1-2/+4
With the recent device handling changes the I2C slave addressing code was broken. With current code, if a slave with the correct address is not found on the bus the last scanned slave on the bus will be addressed. This is wrong. Please find attached a patch to fix it.

2009-12-02pci: move apb specific stuff to apb_pci.cMichael S. Tsirkin3-20/+29
pci code had a TODO to move apb specific pci bridge initialization to apb_pci. Implement this and remove the TODO. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-02vga-pci: Fix access to linear framebufferStefan Weil1-0/+6
Anthony Liguori's patch fixes the problems with vga display in graphical mode and SeaBIOS. I only adapted some values for vga-pci. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-01msix: clear pending bit of an unused vectorMichael S. Tsirkin1-10/+17
PCI spec states: if a masked vector has its Pending bit set, and the associated underlying interrupt events are somehow satisfied (usually by software though the exact manner is function-specific), the function must clear the Pending bit, to avoid sending a spurious interrupt message later when software unmasks the vector. In our case this happens if vector becomes unused. Clear pending bit in this case. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2009-12-01msix: fix reset value for enable bitMichael S. Tsirkin1-1/+2
On reset, we currently clear all bits in msix control register *except* enable bit. This is wrong: the spec says we should clear writeable bits: function mask and enable bit. Correct this. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2009-12-01msix: fix mask bit state after resetMichael S. Tsirkin1-0/+11
PCI spec states that mask bit must be 1 after reset. Make it so. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2009-12-01virtio: do not reset msix state on soft resetMichael S. Tsirkin1-4/+8
msix state is managed by OS, not the driver, so it's wrong to touch it on io from driver. Mark all vectors unused instead. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2009-12-01msix: add helper to unuse all msix entriesMichael S. Tsirkin2-0/+8

2009-12-01pci: simplify (pci_/pcie_mmcfg_)data_read()Michael S. Tsirkin2-37/+11

2009-12-01pci: move pci_data_{read, write}() declaration from pci.h to pci_host.hIsaku Yamahata4-2/+5
Now pci host stuff has been moved from pci.[hc] to pci_host.[hc] so the declaration of pci_data_{read, write}() should be in pci_host.h This patch moves them from pci.h to pci_host.h for consistency.

2009-11-27Revert "vga: do not resize the screen on hw_invalidate"Aurelien Jarno2-4/+3
This causes ctrl+alt+u or ctrl+alt+f to not work when windows hasn't been resized first. Other graphic emulators do resize the screen on hw_invalidate. This reverts commit 0bd8246bfec1dfb2eb959f52db535572c0260f4c.

2009-11-17Convert linux bootrom to external rom and fw_cfgAlexander Graf2-103/+31
We already have a working multiboot implementation that uses fw_cfg to get its kernel module etc. data in int19 runtime now. So what's missing is a working linux boot option rom. While at it I figured it would be a good idea to take the opcode generator out of pc.c and instead use a proper option rom, like we do with multiboot. So here it is - an fw_cfg using option rom for -kernel with linux! Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Convert multiboot to fw_cfg backed data storageAlexander Graf2-14/+34
Right now we load the guest kernel to RAM, fire off the BIOS, hope it doesn't clobber memory and run an option rom that jumps into the kernel. That breaks with SeaBIOS, as that clears memory. So let's read all kernel, module etc. data using the fw_cfg interface when in the int19 handler. This patch implements said mechanism for multiboot.

2009-11-17Introduce rom_copyAlexander Graf2-0/+39
We have several rom helpers currently, but none of them can get us code that spans several roms into a pointer. This patch introduces a function that copies over rom contents. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
