From a268422de8bf1b4c0cb97987b6c329c9f6a3da4b Mon Sep 17 00:00:00 2001 From: Ondrej Zajicek Date: Mon, 12 Feb 2007 00:54:49 -0800 Subject: [PATCH] fbdev driver for S3 Trio/Virge Add a driver for S3 Trio / S3 Virge. Driver is tested with most versions of S3 Trio and with S3 Virge/DX, on i386. (akpm: We kind-of have support for this hardware already, but... virgefb.c - amiga/zorro specific, - broken (according to Kconfig), - uses obsolete/nonexistent interface (struct display_switch) - recent Adrian Bunk's patch removes this driver S3triofb.c - ppc/openfirmware specific - minimal functionality - broken (according to Kconfig), - uses obsolete/nonexistent interface (struct display_switch) ) Signed-off-by: Ondrej Zajicek Cc: James Simmons Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/video/Kconfig | 19 + drivers/video/Makefile | 2 + drivers/video/s3fb.c | 1180 +++++++++++++++++++++++++++++++++++++++++++++++ drivers/video/svgalib.c | 632 +++++++++++++++++++++++++ 4 files changed, 1833 insertions(+) create mode 100644 drivers/video/s3fb.c create mode 100644 drivers/video/svgalib.c (limited to 'drivers') diff --git a/drivers/video/Kconfig b/drivers/video/Kconfig index 45fe65d8d7a..3ab06317264 100644 --- a/drivers/video/Kconfig +++ b/drivers/video/Kconfig @@ -85,6 +85,14 @@ config FB_CFB_IMAGEBLIT blitting.
