2018-09-27display/stdvga: add edid support.Gerd Hoffmann
This patch adds edid support to the qemu stdvga. It is turned off by default and can be enabled with the new edid property. The patch also adds xres and yres properties to specify the video mode you want the guest use. Works only with edid enabled and updated guest driver. The mmio bar of the stdvga has some unused address space at the start. It was reserved just in case it'll be needed for virtio, but it turned out to not be needed for that. So let's use that region to place the EDID data block there. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20180925075646.25114-6-kraxel@redhat.com

2018-09-27display/edid: add edid generator to qemu.Gerd Hoffmann
EDID is a metadata format to describe monitors. On physical hardware the monitor has an eeprom with that data block which can be read over i2c bus. On a linux system you can usually find the EDID data block in /sys/class/drm/$card/$connector/edid. xorg ships a edid-decode utility which you can use to turn the blob into readable form. I think it would be a good idea to use EDID for virtual displays too. Needs changes in both qemu and guest kms drivers. This patch is the first step, it adds an generator for EDID blobs to qemu. Comes with a qemu-edid test tool included. With EDID we can pass more information to the guest. Names and serial numbers, so the guests display configuration has no boring "Unknown Monitor". List of video modes. Display resolution, pretty important in case we want add HiDPI support some day.

2018-08-24hw/display/bcm2835_fb: Validate config settingsPeter Maydell
Validate the config settings that the guest tries to set. The wiki page documentation is not really accurate here: generally rather than failing requests to set bad parameters, the hardware will just clip them to something sensible. Validate the most important parameters: sizes and the viewport offsets. This prevents the framebuffer code from trying to read out-of-range memory. In the property handling code, we validate the new parameters every time we encounter a tag that sets them. This means we validate the config multiple times if the request includes multiple config-setting tags, but the code would require significant restructuring to do a validation only once but still return the clipped settings for get-parameter tags and the buffer allocation tag. Validation of settings made via the older bcm2835_fb_mbox_push() function will be done in the next commit.

2018-08-24hw/display/bcm2835_fb: Fix handling of virtual framebufferPeter Maydell
The raspi framebuffir in bcm2835_fb supports the definition of a virtual "viewport", which is smaller than the full physical framebuffer size and at an adjustable offset within it. Only the viewport area is sent to the screen. This allows the guest to do things like double buffering, or scrolling by adjusting the viewport origin. Currently QEMU doesn't implement this at all. Add support for this feature: * the property mailbox code needs to distinguish the virtual width/height from the physical width/height * the framebuffer code needs to do something with the virtual width/height/origin information Note that the wiki documentation on the semantics of the virtual and physical height and width has it the wrong way around -- the virtual size is the size of the allocated buffer, and the physical size is the size of the display, so the virtual size is always the same as or larger than the physical. If the viewport size is set smaller than the physical screen size, we ignore the viewport settings completely and just display the physical screen area.

2018-08-24hw/misc/bcm2835_fb: Move config fields to their own structPeter Maydell
The handling of framebuffer properties in the bcm2835_property code is a bit clumsy, because for each of the many fb related properties we try to track the value we're about to set and whether we're going to be setting a value, and then we hand all the new values off to the framebuffer via a function which takes them all as separate arguments. It would be simpler if the property code could easily copy all the framebuffer's current settings, update them with the new specified values and then ask the framebuffer to switch to the new set. As the first part of this refactoring, pull all the fb config settings fields in BCM2835FBState out into their own struct.

2018-07-17hw/display/xlnx_dp: Move problematic code from instance_init to realizePaolo Bonzini
aux_create_slave() calls qdev_init_nofail() which in turn "realizes" the corresponding object. This is unlike qdev_create(), and it is wrong because qdev_init_nofail() must not be called from an instance_init function. Move qdev_init_nofail() and the subsequent aux_map_slave into the caller's realize function. There are two more bugs that needs to be fixed here, too, where the objects are created but not added as children. Therefore when you call object_unparent on them, nothing happens. In particular dpcd and edid give you an infinite loop in bus_unparent, because device_unparent is not called and does not remove them from the list of devices on the bus.

2018-06-27compiler: add a sizeof_field() macroStefan Hajnoczi
Determining the size of a field is useful when you don't have a struct variable handy. Open-coding this is ugly. This patch adds the sizeof_field() macro, which is similar to typeof_field(). Existing instances are updated to use the macro.

2018-06-26ramfb: fix overflowGerd Hoffmann
> CID 1393621: (OVERFLOW_BEFORE_WIDEN) > Potentially overflowing expression "stride * s->height" with type "unsigned > int" (32 bits, unsigned) is evaluated using +32-bit arithmetic, and then used > in a context that expects an expression of type "hwaddr" (64 bits, unsigned). Fix by changing stride from uint32_t to hwaddr. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20180626083120.19515-1-kraxel@redhat.com

2018-06-21sm501: Fix hardware cursor color conversionSebastian Bauer
According to the sm501 specs the hardware cursor colors are to be given in the rgb565 format, but the code currently interprets them as bgr565. Therefore, the colors of the hardware cursors are wrong in the QEMU display, e.g., the standard mouse pointer of AmigaOS appears blue instead of red. This change fixes this issue by replacing the existing naive bgr565 => rgb888 conversion with a standard rgb565 => rgb888 one that also scales the color component values properly.
