The code looks good, and I trust your knowledge of Amiga much more than my own. It would be nice if someone actually has this hardware and can test the patch... Anyone? Anyone? Lars? Beuler? There was a trivial problem applying the patch - one of the whitespace fixes choked, so I took it out of the patch (below). -dte --- Cirrusfb updates: - Cirrusfb depends on Zorro or PCI - Revive Zorro support, using new Zorro driver framework - Merge PCI and Zorro code where possible - Use C99 initializers - Kill superfluous whitespace - #undef I/O ops before redefining them on Amiga From: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: David Eger <eger@havoc.gtf.org> --- linux-2.6.8-rc2/drivers/video/Kconfig 2004-07-15 23:14:59.000000000 +0200 +++ linux-m68k-2.6.8-rc2/drivers/video/Kconfig 2004-07-19 21:06:17.000000000 +0200 @@ -40,7 +40,7 @@ config FB_CIRRUS tristate "Cirrus Logic support" - depends on FB && (AMIGA || PCI) + depends on FB && (ZORRO || PCI) ---help--- This enables support for Cirrus Logic GD542x/543x based boards on Amiga: SD64, Piccolo, Picasso II/II+, Picasso IV, or EGS Spectrum. --- linux-2.6.8-rc2/drivers/video/cirrusfb.c 2004-07-18 15:55:33.000000000 +0200 +++ linux-m68k-2.6.8-rc2/drivers/video/cirrusfb.c 2004-07-19 21:14:50.000000000 +0200 @@ -5,8 +5,8 @@ * * Contributors (thanks, all!) * - * David Eger: - * Overhaul for Linux 2.6 + * David Eger: + * Overhaul for Linux 2.6 * * Jeff Rugen: * Major contributions; Motorola PowerStack (PPC and PCI) support, @@ -145,9 +145,6 @@ * a run-time table? */ static const struct cirrusfb_board_info_rec { - cirrusfb_board_t btype; /* chipset enum, not strictly necessary, as - * cirrusfb_board_info[] is directly indexed - * by this value */ char *name; /* ASCII name of chipset */ long maxclock[5]; /* maximum video clock */ /* for 1/4bpp, 8bpp 15/16bpp, 24bpp, 32bpp - numbers from xorg code */ @@ -164,104 +161,115 @@ unsigned char sr1f; /* SR1F VGA initial register value */ } cirrusfb_board_info[] = { - { BT_NONE, }, /* dummy record */ - { BT_SD64, - "CL SD64", - { 140000, 140000, 140000, 140000, 140000, }, /* guess */ - /* the SD64/P4 have a higher max. videoclock */ - TRUE, - TRUE, - TRUE, - 0xF0, - 0xF0, - 0, /* unused, does not multiplex */ - 0xF1, - 0, /* unused, does not multiplex */ - 0x20 }, - { BT_PICCOLO, - "CL Piccolo", - { 90000, 90000, 90000, 90000, 90000 }, /* guess */ - TRUE, - TRUE, - FALSE, - 0x80, - 0x80, - 0, /* unused, does not multiplex */ - 0x81, - 0, /* unused, does not multiplex */ - 0x22 }, - { BT_PICASSO, - "CL Picasso", - { 90000, 90000, 90000, 90000, 90000, }, /* guess */ - TRUE, - TRUE, - FALSE, - 0x20, - 0x20, - 0, /* unused, does not multiplex */ - 0x21, - 0, /* unused, does not multiplex */ - 0x22 }, - { BT_SPECTRUM, - "CL Spectrum", - { 90000, 90000, 90000, 90000, 90000, }, /* guess */ - TRUE, - TRUE, - FALSE, - 0x80, - 0x80, - 0, /* unused, does not multiplex */ - 0x81, - 0, /* unused, does not multiplex */ - 0x22 }, - { BT_PICASSO4, - "CL Picasso4", - { 135100, 135100, 85500, 85500, 0 }, - TRUE, - FALSE, - TRUE, - 0x20, - 0x20, - 0, /* unused, does not multiplex */ - 0x21, - 0, /* unused, does not multiplex */ - 0 }, - { BT_ALPINE, - "CL Alpine", - { 85500, 85500, 50000, 28500, 0}, /* for the GD5430.
