2012-11-01usb/ehci: Guard definition of EHCI_DEBUGPeter Crosthwaite
Guard against re-definition of EHCI_DEBUG. Allows for turning on of debug info from configure (using --qemu-extra-cflags="-DEHCI_DEBUG=1") rather than source code hacking. Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-11-01usb/ehci: seperate out PCIismsPeter Crosthwaite
Seperate the PCI stuff from the EHCI components. Extracted the PCIDevice out into a new wrapper struct to make EHCIState non-PCI-specific. Seperated tho non PCI init component out into a seperate "common" init function. Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-11-01xhci: s/xhci_update_port/xhci_port_update/Gerd Hoffmann
Rename the function for xhci_port_* naming scheme, also drop the xhci parameter as port carries a pointer to xhci anyway. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-11-01xhci: add {get,set}_field macros & enum for plsGerd Hoffmann
Add {get,set}_field macros (simliar to ehci) to read and update some bits of a word. Put them into use for updating pls (port link state) values. Also add a enum for pls values. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-11-01pixman: add submoduleGerd Hoffmann
Add pixman submodule as fallback for old distros. Picking version 0.18.4. This is shipped by rhel6 and also the minimum version needed by spice so this should serve well as baseline. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-11-01console: remove DisplayAllocatorGerd Hoffmann

Unused code. 'nuff said. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-11-01vga: fix text mode updatingGerd Hoffmann
With both text (curses) and graphics (vnc/sdl/spice/...) display active vga text mode emulation fails to update both correctly. Depending on whenever vga_update_text() or vga_draw_text() happens to be called first only the text display or only the graphics display will see display resolution changes and full redraws. Fix it by calling both text/gfx resize functions in both code paths and keep track of full screen redraws needed in VGACommonState fields. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-11-01console: untangle gfx & txt updatesGerd Hoffmann
Stop abusing displaysurface fields for text mode displays. (bpp = 0, width = cols, height = lines). Add flags to displaystate indicating whenever text mode display (curses) or gfx mode displays (sdl, vnc, ...) are present. Add separate displaychangelistener callbacks for text / gfx mode resize & updates. This allows to enable gfx and txt diplays at the same time and also paves the way for more cleanups in the future.

2012-11-01console: move set_mouse + cursor_define callbacksGerd Hoffmann
When adding DisplayChangeListeners the set_mouse and cursor_define callbacks have been left in DisplayState for some reason. Fix it. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-11-01console: add unregister_displaychangelistenerGerd Hoffmann
Also change the way the gui_timer is initialized: each time a displaychangelistener is registered or unregistered we'll check whether we need a timer (due to dpy_refresh callback being present) and if so setup a timer, otherwise zap it. This way the gui timer works correctly with displaychangelisteners coming and going. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-11-01pseries: Cleanup duplications of ics_valid_irq() codeDavid Gibson
A couple of places in xics.c open-coded the same logic as is already implemented in ics_valid_irq(). This patch fixes the code duplication. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-11-01pseries: Clean up inconsistent variable name in xics.cDavid Gibson
Throughout xics.c 'nr' is used to refer to a global interrupt number, and 'server' is used to refer to an interrupt server number (i.e. CPU number). Except in icp_set_mfrr(), where 'nr' is used as a server number. Fix this confusing inconsistency.

2012-11-01target-ppc: Extend FPU state for newer POWER CPUsDavid Gibson
This patch adds some extra FPU state to CPUPPCState. Specifically, fpscr is extended to a target_ulong bits, since some recent (64 bit) CPUs now have more status bits than fit inside 32 bits. Also, we add the 32 VSR registers present on CPUs with VSX (these extend the standard FP regs, which together with the Altivec/VMX registers form a 64 x 128bit register file for VSX). We don't actually support the instructions using these extra registers in TCG yet, but we still need a place to store the state so we can sync it with KVM and savevm/loadvm it. This patch updates the savevm code to not fail on the extended state, but also does not actually save it - that's a project for another patch.

2012-11-01target-ppc: Rework storage of VPA registration stateDavid Gibson
We change the storage of the VPA information to explicitly use fixed size integer types which will make life easier for syncing this data with KVM, which we will need in future.

2012-11-01Revert "PPC: pseries: Remove hack for PIO window"David Gibson
This reverts commit a178274efabcbbc5d44805b51def874e47051325. Contrary to that commit's message, the users of old_portio are not all gone. In particular VGA still uses it via portio_list_add(). Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-11-01e1000: pre-initialize RAH/RAL registersGabriel L. Somlo
Some guest operating systems' drivers (Mac OS X in particular) fail to properly initialize the Receive Address registers (probably expecting them to be pre-initialized by an earlier component, such as a specific proprietary BIOS). This patch pre-initializes the RA registers, allowing OS X networking to function properly. Other guest operating systems are not affected, and free to (re)initialize these registers during boot. [According to the datasheet the Address Valid bits in the RA registers are cleared on PCI or software reset. This patch adds the NIC's MAC address and sets Address Valid on reset. So we diverge from real hardware behavior here. -- Stefan] Signed-off-by: Gabriel Somlo <somlo@cmu.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2012-11-01net: Reject non-netdevs in qmp_netdev_del()Stefan Hajnoczi
The netdev_del command crashes when given a -net device, because it calls qemu_opts_del(NULL). Check that this is a -netdev before attempting to delete it and the QemuOpts. Note the subtle change from qemu_find_opts_err("netdev", errp) to qemu_find_opts_err("netdev", NULL). Since "netdev" is a built in options group and we don't check for NULL return anyway, there's no use in passing errp here. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2012-11-01net: use "socket" model name for UDP socketsLei Li
Fix the problem that can not delete the udp socket. It's caused by passing "udp" model to net_socket_udp_init, but we do not have "udp" model in our model list.

2012-10-31target-mips: don't flush extra TLB on permissions upgradeAurelien Jarno

2012-10-31target-mips: use deposit instead of hardcoded versionAurelien Jarno
Use the deposit op instead of and hardcoded bit field insertion. It allows the host to emit the corresponding instruction if available. At the same time remove the (lsb > msb) test. The MIPS64R2 instruction set manual says "Because of the instruction format, lsb can never be greater than msb, so there is no UNPREDICATABLE case for this instruction." (Bug reported as LP:1071149.)

2012-10-31target-mips: don't use local temps for store conditionalAurelien Jarno

2012-10-31target-mips: implement unaligned loads using TCGAurelien Jarno
Load/store from helpers should be avoided as they are quite inefficient. Rewrite unaligned loads instructions using TCG and aligned loads. The number of actual loads operations to implement an unaligned load instruction is reduced from up to 8 to 1. Note: As we can't rely on shift by 32 or 64 undefined behaviour, the code loads already shift by one constants.

2012-10-31target-mips: use softfloat constants when possibleAurelien Jarno
softfloat already has a few constants defined, use them instead of redefining them in target-mips. Rename FLOAT_SNAN32 and FLOAT_SNAN64 to FP_TO_INT32_OVERFLOW and FP_TO_INT64_OVERFLOW as even if they have the same value, they are technically different (and defined differently in the MIPS ISA).

2012-10-31target-mips: cleanup float to int conversion helpersAurelien Jarno

For each FPU instruction that can trigger an FPU exception, to call call update_fcr31() after. Remove the manual NaN assignment in case of float to float operation, as softfloat is already taking care of that. However for float to int operation, the value has to be changed to the MIPS one. In the cvtpw_ps case, the two registers have to be handled separately to guarantee a correct final value in both registers.
