hw/display : Add device DM163

2024-04-30T15:02:43Z

This device implements the IM120417002 colors shield v1.1 for Arduino (which relies on the DM163 8x3-channel led driving logic) and features a simple display of an 8x8 RGB matrix. The columns of the matrix are driven by the DM163 and the rows are driven externally.

ramfb: add migration support

2023-10-18T08:10:49Z

Implementing RAMFB migration is quite straightforward. One caveat is to treat the whole RAMFBCfg as a blob, since that's what is exposed to the guest directly. This avoid having to fiddle with endianness issues if we were to migrate fields individually as integers. The devices using RAMFB will have to include ramfb_vmstate in their migration description.

include: Include headers where needed

2023-01-08T06:54:22Z

A number of headers neglect to include everything they need. They compile only if the headers they need are already included from elsewhere. Fix that.

xlnx_dp: Introduce a vblank signal

2022-06-08T18:38:47Z

Add a periodic timer which raises vblank at a frequency of 30Hz. Note that this is a migration compatibility break for the xlnx-zcu102 board type.

xlnx_dp: fix the wrong register size

2022-06-08T18:38:47Z

The core and the vblend registers size are wrong, they should respectively be 0x3B0 and 0x1E0 according to: https://www.xilinx.com/htmldocs/registers/ug1087/ug1087-zynq-ultrascale-registers.html. Let's fix that and use macros when creating the mmio region. Fixes: 58ac482a66d ("introduce xlnx-dp") Signed-off-by: Frederic Konrad Reviewed-by: Edgar E.

macfb: increase number of registers saved in MacfbState

2022-03-09T09:29:10Z

The MacOS toolbox ROM accesses a number of addresses between 0x0 and 0x200 during initialisation and resolution changes. Whilst the function of many of these registers is unknown, it is worth the minimal cost of saving these extra values as part of migration to help future-proof the migration stream for the q800 machine as it starts to stabilise. Note this is a migration break, but since there are upcoming incompatible changes for the q800 machine (and migration does not even succeed without these patches) then this is not an issue.

macfb: don't use special irq_state and irq_mask variables in MacfbState

2022-03-09T09:29:10Z

The current IRQ state and IRQ mask are handled exactly the same as standard register accesses, so store these values directly in the regs array rather than having separate variables for them.
