2012-01-07sm501: Fix size of color_regStefan Weil
color_reg is expected to hold 32 bit values, so it was too small. This bug was reported by coverity: hw/sm501.c:624: result_independent_of_operands: color_reg >> 16 is 0 regardless of the values of its operands. This occurs as the bitwise first operand of '&'.

2012-01-04vmstate, memory: decouple vmstate from memory APIAvi Kivity
Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: Avi Kivity <avi@redhat.com>

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.

These will be used to generate unique id strings for ramblocks. The name field is required, the device pointer is optional as most callers don't have a device.

2010-05-15sh: sm501: add 2D engine supportShin-ichiro KAWASAKI
In linux kernel v2.6.33, sm501 frame buffer driver modified to support 2D graphics engine on sm501 chip. One example is "fill rectangle" operation. But current qemu's sm501 emulation doesn't support it. This results in graphics console disturbance. This patch introduces sm501 2D graphics engine emulation and solve this problem. Add SM501 2D hardware engine support. - Add 2D engine register set read/write handlers. - Support 'fill rectangle'. Other operations are left for future work. - Update SM501 support status comment.

2009-04-19Adds SM501 usb host emulation feature.aurel32
It makes usb keyboard available for sh4/r2d system emulation. The changes for "hw/usb-ohci.c" are as follows. - 'localmem_base' is introduced as OHCIState struct member. SM501 has a local memory, and it is used to pass and receive data with OHCI driver. OHCI driver accesses it with SH4 physical memory address, and SM501 accesses it with SM501 local address. 'localmem_base' holds where the SM501 local memory is mapped into SH4 physical address space. - Memory access functions modified to adjust address with 'localmem_base'. The functions are, ohci_read_*(), ohci_put_*(), and ohci_copy_*(). - ohci_read_hcca() and ohci_put_hcca() are introduced for more consistent implementation. For other source files, it does, - introduces usb_ohci_init_sm501(). - adds irq argument for SM501 initialization, to emulate USB interrupts.

2009-03-13DisplayAllocator interface (Stefano Stabellini)aliguori
Hi all, this patch adds a DisplayAllocator interface that allows display frontends (sdl in particular) to provide a preallocated display buffer for the graphical backend to use. Whenever a graphical backend cannot use qemu_create_displaysurface_from because its own internal pixel format cannot be exported directly (text mode or graphical mode with color depth 8 or 24), it creates another display buffer in memory using qemu_create_displaysurface and does the conversion. This new buffer needs to be blitted into the sdl surface buffer every time we need to update portions of the screen. We can avoid this using the DisplayAllocator interace: sdl provides its own implementation of qemu_create_displaysurface, giving back the sdl surface buffer directly (as we used to do before the DisplayState changes). Since the buffer returned by sdl could be in bgr format we need to put back in the handlers of that case. This approach is good if the two following conditions are true: 1) the sdl surface is a software surface that resides in main memory; 2) the host display color depth is either 16 or 32 bpp. If first condition is false we can have bad performances using sdl and vnc together. If the second condition is false performances are certainly not going to improve but they shouldn't get worse either. The first condition is always true, at least on linux/X11 systems; but I believe is true also on other platforms. The second condition is true in the vast majority of the cases. This patch should also have the good side effect of solving the sdl 2D slowness malc was reporting on MacOS, because SDL_BlitSurface is not going to be called anymore when the guest is in text mode or 24bpp. However the root problem is still present so I suspect we may still see some slowness on MacOS when the guest is in 32 or 16 bpp. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6839 c046a42c-6fe2-441c-8c8c-71466251a162
2009-01-16graphical_console_init change (Stefano Stabellini)aliguori
Patch 5/7 This patch changes the graphical_console_init function to return an allocated DisplayState instead of a QEMUConsole. This patch contains just the graphical_console_init change and few other modifications mainly in console.c and vl.c. It was necessary to move the display frontends (e.g. sdl and vnc) initialization after machine->init in vl.c. This patch does *not* include any required changes to any device, these changes come with the following patches. Patch 6/7 This patch changes the QEMUMachine init functions not to take a DisplayState as an argument because is not needed any more; In few places the graphic hardware initialization function was called only if DisplayState was not NULL, now they are always called. Apart from these cases, the rest are all mechanical substitutions. Patch 7/7 This patch updates the graphic device code to use the new graphical_console_init function. As for the previous patch, in few places graphical_console_init was called only if DisplayState was not NULL, now it is always called. Apart from these cases, the rest are all mechanical substitutions.

2009-01-15remove bgr (Stefano Stabellini)aliguori
Do not handle bgr host displays in the backends. Right now a bgr flag exists so that sdl can set it, if the SDL_Surface is bgr. Afterwards the graphic device (e.g. vga.c) does the needed conversion. With this patch series is sdl that is responsible for rendering the format provided by the graphic device that must provide a DisplaySurface (ds->surface) in 16 or 32 bpp, rgb. Afterwards sdl creates a SDL_Surface from the given DisplaySurface and blits it into the main SDL_Surface using SDL_BlitSurface. Everything is handled by sdl transparently, because SDL_BlitSurface is perfectly capable of handling bgr displays by itself.
