2012-10-30cirrus_vga: allow configurable vram sizeMarcelo Tosatti
Allow RAM size to be configurable for cirrus, to allow migration compatibility from qemu-kvm. Acked-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-08-15Add one new file vga-pci.h and cleanup on all platformszhlcindy@gmail.com
Functions pci_vga_init() and pci_cirrus_vga_init() are declared in pc.h. That prevents other platforms (e.g. sPAPR) to use them. This patch is to create one new file vga-pci.h and move the declarations to vga-pci.h, so that they can be shared by all platforms. This patch also cleans up on all platforms.

2012-06-22vga: make vram size configurableGerd Hoffmann
Zap the global VGA_RAM_SIZE #define, make the vga ram size configurable for standard vga and vmware vga. cirrus and qxl are left with a fixed size (and private VGA_RAM_SIZE #define) for now. qxl needs some non-trivial adjustments in the mode list handling deal with a runtime-configurable size, which calls for a separate qxl patch. cirrus emulates cards which have 2 MB (isa) and 4 MB (pci), so I guess it would make sense to use these sizes. That change would break migration though, so I left it fixed at 8 MB size. Making it configurabls is pretty pointless for cirrus as we have to match real hardware.

2012-02-15qom: Unify type registrationAndreas Färber
Replace device_init() with generalized type_init(). While at it, unify naming convention: type_init([$prefix_]register_types) Also, type_init() is a function, so add preceding blank line where necessary and don't put a semicolon after the closing brace.

2012-02-04vga: move Cirrus VGA template to its own fileBlue Swirl

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-01-27qdev: move qdev->info to classAnthony Liguori

2011-01-04cirrus_vga: fix division by 0 for color expansion ropAurelien Jarno
Commit d85d0d3883f5a567fa2969a0396e42e0a662b3fa introduces a regression with Windows ME that leads to a division by 0 and a crash. It uses the color expansion rop with the source pitch set to 0. This is something allowed, as the manual explicitely says "When the source of color-expand data is display memory, the source pitch is ignored.". This patch fixes this regression by computing sx, sy and others variables only if they are going to be used later, that is for a plain copy ROP. It basically consists in moving code.

2010-12-11Add endianness as io mem parameterAlexander Graf
As stated before, devices can be little, big or native endian. The target endianness is not of their concern, so we need to push things down a level. This patch adds a parameter to cpu_register_io_memory that allows a device to choose its endianness. For now, all devices simply choose native endian, because that's the same behavior as before.
