RESENDING SINCE MAILING LIST HAS NOT YET RECEIVED IT YET... -----Original Message----- From: Strelchun, Timothy Sent: Friday, November 13, 2009 12:27 AM To: 'directfb-dev@directfb.org' Subject: [PATCH] linux-fusion-8.1.1 Dynamic Major Number improvement (was Re: Device ID issue in linux-fusion module)
Hi guys,
Here's a patch for linux-fusion-8.1.1 that handles dynamic major number
generation. In the interest of quickly getting this out, I have not stripped
the original unmodified code (which the compile will revert back to if
INTELCE_CHANGES is not defined).
I also attached a full patch for the changes we did as described below. Not
all, but most of the makefile changes are to custom the package work to build
as a subcomponent in a different build environment.
Files: Makefile
Modified to allow for proper building on kernel 2.6.28
Files: linux/drivers/char/fusion/Makefile-2.6
linux/drivers/char/fusion/fusiondev.c
tests/calls.c
tests/latency.c
tests/throughput.c
tests/Makefile
Makefile
Modified makefiles to not depend on the host's kernel because the
target's kernel is often different than the host's kernel and was
modifying how the compile occurred.
Modified makefile to include IntelCE_Version.o and use DFB_FUSION_NAME
environment variable in KERNEL_INCLUDE path.
Modified device registration to use a dynamically allocated major number.
Added INTELCE_CHANGES define to the Makefile.
Modified tests to use /dev/fusion0 instead of /dev/fusion/0.
Modified the 'calls' test to not use the FCEF_ONEWAY flag, which caused
failures on the FUSION_CALL_RETURN ioctl.
Regards,
Timothy
