* hw/m68k: add Nubus macfb video cardLaurent Vivier2019-10-281-0/+64
| | | | | | | | | | | | | | This patch adds support for a graphic framebuffer device. This device can be added as a sysbus device or as a NuBus device. It is accessed as a framebuffer but the color palette can be set.

* Include hw/qdev-properties.h lessMarkus Armbruster2019-08-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

* include: Make headers more self-containedMarkus Armbruster2019-08-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in 2016, we discussed[1] rules for headers, and these were generally liked: 1. Have a carefully curated header that's included everywhere first. We got that already thanks to Peter: osdep.h. 2. Headers should normally include everything they need beyond osdep.h. If exceptions are needed for some reason, they must be documented in the header. If all that's needed from a header is typedefs, put those into qemu/typedefs.h instead of including the header. 3. Cyclic inclusion is forbidden. This patch gets include/ closer to obeying 2. It's actually extracted from my "[RFC] Baby steps towards saner headers" series[2], which demonstrates a possible path towards checking 2 automatically. It passes the RFC test there.

* display/edid: add edid generator to qemu.Gerd Hoffmann2018-09-271-0/+18
| | | | | | | | | | | | | | | | | | | | | | | 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.

* hw/display/bcm2835_fb: Validate config settingsPeter Maydell2018-08-241-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* hw/display/bcm2835_fb: Fix handling of virtual framebufferPeter Maydell2018-08-241-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | 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.

* hw/display: add ramfb, a simple boot framebuffer living in guest ramGerd Hoffmann2018-06-181-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | The boot framebuffer is expected to be configured by the firmware, so it uses fw_cfg as interface. Initialization goes as follows: (1) Check whenever etc/ramfb is present. (2) Allocate framebuffer from RAM. (3) Fill struct RAMFBCfg, write it to etc/ramfb. Done. You can write stuff to the framebuffer now, and it should appear automagically on the screen. Note that this isn't very efficient because it does a full display update on each refresh. No dirty tracking. Dirty tracking would have to be active for the whole ram slot, so that wouldn't be very efficient either. For a boot display which is active for a short time only this isn't a big deal. As permanent guest display something better should be used (if possible). This is the ramfb core code. Some windup is needed for display devices which want have a ramfb boot display.
