hppa: Artist graphics driver fixes for HP-UX and keyboard fix in firmware boot console
This series updates the SeaBIOS-hppa firmware to version 5, in which additional HP fonts were added to the firmware and the firmware boot console was fixed to accept input from the emulated PS/2 keyboard when running in graphical mode (serial console was working before already). To test use the "-boot menu=on" qemu option. The artist graphics card driver got various fixes when running the X11-Windows on HP-UX: - fixes the horizontal and vertical postioning of the X11 cursor with HP-UX - allows X11 to blank the screen (e.g. screensaver) - allows the X11 driver to turn the X11 cursor on/off Signed-off-by: Helge Deller <deller@gmx.de> -- Changes compared to version 2 of this series: - Fixed style issues in the X-cursor positioning patch (noticed by Mark Cave-Ayland) Changes compared to version 1 of this series: - Added some Acked-by's from Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> - SeaBIOS-hppa v5 instead of v4 (PS/2 keyboard now works in boot console) - integrated artist X11 X-cusor positioning fix (which was sent serperately before) -- This series should apply cleanly on git head and can be pulled for testing from: https://github.com/hdeller/qemu-hppa.git artist-cursor-fix-final -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQS86RI+GtKfB8BJu973ErUQojoPXwUCYoUcLwAKCRD3ErUQojoP X/joAQCmuV5MD+BTWf91fRTfzXSfOYSp1XahTaItUldKG2ZBWQD+Lflhsoyg4xLd 2daeDRN1tH2HWldjnCPyMyZ5Ag97PwY= =ZrTm -----END PGP SIGNATURE----- Merge tag 'artist-cursor-fix-final-pull-request' of https://github.com/hdeller/qemu-hppa into staging hppa: Artist graphics driver fixes for HP-UX and keyboard fix in firmware boot console This series updates the SeaBIOS-hppa firmware to version 5, in which additional HP fonts were added to the firmware and the firmware boot console was fixed to accept input from the emulated PS/2 keyboard when running in graphical mode (serial console was working before already).
