2011-08-22440fx: fix PAM, PCI holesAvi Kivity
The current implementation of PAM and the PCI holes is broken in several ways: - PCI BARs are not restricted to the PCI hole (a BAR may hide memory) - PCI devices do not respect PAM (if a PCI device maps a region while PAM maps the region to RAM, the request will be honored) This patch fixes things by introducing a pci address space, and using memory region aliases to represent PAM regions, SMRAM, and PCI holes. The memory hierarchy looks something like system_memory | +--- low memory alias (0-0xe0000000) | | | +-- ram@0 | +--- high memory alias (0x100000000-EOM) | | | +-- ram@0xe0000000 | +--- pci hole alias (end of low memory-0x100000000) | | | +-- pci@end-of-low-memory | | +--- pam[n] (0xc0000-0xc3fff etc) (when set to pci, priority 1) | | | +-- pci@0xc4000 etc | +--- smram (0xa0000-0xbffff) (when set to pci/vga, priority 1) | +-- pci@0xa0000 etc ram (simple ram region) pci | +--- BARn | +--- VGA 0xa0000-0xbffff | +--- ROMs Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-08-12pc: make vgabios exit port more usefulAnthony Liguori
We've always listened on port 501 for vgabios panic messages. In the entire time I've worked on QEMU, I've never actually seen a vgabios panic message :-) If we change the semantics of this port a little bit, it makes it possible to use it for more interesting use-cases. I chose this approach instead of adding a new I/O port because it avoids having a guest visible change. This change allows single-byte access to port 501 and also uses the value written to construct an exit code. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

This patch moves above_4g_mem_size and below_4g_mem_size calculation in the caller of pc_memory_init (pc_init1).

2011-03-12pc: fix wrong CMOS values for floppy drivesBlue Swirl
Before commit 63ffb564dca94f8bda01ed6d209784104630a4d2, states for floppy drives were calculated in fdc.c:fd_revalidate(). There it is also considered whether a disk is inserted or not. The commit didn't copy the logic completely to pc.c, which caused a regression. Fix by adding the same check also to pc.c.

2010-12-09spice: add qxl deviceGerd Hoffmann
qxl is a paravirtual graphics card. The qxl device is the bridge between the guest and the spice server (aka libspice-server). The spice server will send the rendering commands to the spice client, which will actually render them. The spice server is also able to render locally, which is done in case the guest wants read something from video memory. Local rendering is also used to support display over vnc and sdl. qxl is activated using "-vga qxl". qxl supports multihead, additional cards can be added via '-device qxl".

2010-07-02pc: Fix CMOS info for drives defined with -deviceMarkus Armbruster
Drives defined with -drive if=ide get get created along with the IDE controller, inside machine->init(). That's before cmos_init(). Drives defined with -device get created during generic device init. That's after cmos_init(). Because of that, CMOS has no information on them (type, geometry, translation). Older versions of Windows such as XP reportedly choke on that. Split off the part of CMOS initialization that needs to know about -device devices, and turn it into a reset handler, so it runs after device creation.

2010-06-14pass info about hpets to seabios.]Gleb Natapov
Currently HPET ACPI table is created regardless of whether qemu actually created hpet device. This may confuse some guests that don't check that hpet is functional before using it. Solve this by passing info about hpets in qemu to seabios via fw config interface. Additional benefit is that seabios no longer uses hard coded hpet configuration. Proposed interface supports up to 8 hpets. This is the number defined by hpet spec. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-06-13hpet/rtc: Rework RTC IRQ replacement by HPETJan Kiszka
Allow the intercept the RTC IRQ for the HPET legacy mode. Then push routing to IRQ8 completely into the HPET. This allows to turn hpet_in_legacy_mode() into a private function. Furthermore, this stops the RTC from clearing IRQ8 even if the HPET is in control. This patch comes with a side effect: The RTC timers will no longer be stoppend when there is no IRQ consumer, possibly causing a minor performance degration. But as the guest may want to redirect the RTC to the SCI in that mode, it should normally disable unused IRQ source anyway.
