c729203d - Annotate hardware config module parameters in drivers/video/

Tue, 04 Apr 2017 15:54:29 +0000

Annotate hardware config module parameters in drivers/video/When the kernel is running in secure boot mode, we lock down the kernel toprevent userspace from modifying the running kernel image. Whilst thisincludes prohibiting access to things like /dev/mem, it must also preventaccess by means of configuring driver modules in such a way as to cause adevice to access or modify the kernel image.To this end, annotate module_param* statements that refer to hardwareconfiguration and indicate for future reference what type of parameter theyspecify. The parameter parser in the core sees this information and canskip such parameters with an error message if the kernel is locked down.The module initialisation then runs as normal, but just sees whatever thedefault values for those parameters is.Note that we do still need to do the module initialisation because somedrivers have viable defaults set in case parameters aren't specified andsome drivers support automatic configuration (e.g. PNP or PCI) in additionto manually coded parameters.This patch annotates drivers in drivers/video/.Suggested-by: Alan Cox Signed-off-by: David Howells Acked-by: Bartlomiej Zolnierkiewicz cc: Tomi Valkeinen cc: linux-fbdev@vger.kernel.org List of files: /linux-6.15/drivers/video/fbdev/n411.c

f7018c21 - video: move fbdev to drivers/video/fbdev

Thu, 13 Feb 2014 13:31:38 +0000

video: move fbdev to drivers/video/fbdevThe drivers/video directory is a mess. It contains generic video relatedfiles, directories for backlight, console, linux logo, lots of fbdevdevice drivers, fbdev framework files.Make some order into the chaos by creating drivers/video/fbdevdirectory, and move all fbdev related files there.No functionality is changed, although I guess it is possible that somesubtle Makefile build order related issue could be created by thispatch.Signed-off-by: Tomi Valkeinen Acked-by: Laurent Pinchart Acked-by: Geert Uytterhoeven Acked-by: Rob Clark Acked-by: Jingoo Han Acked-by: Daniel Vetter List of files: /linux-6.15/drivers/video/fbdev/n411.c
