Hello ,everyone
I meet some problems when I compile the mali-400 kernel drivers
I copy the mali0400 drivers to the linux kernel and config the linux kernel .but when I compile the kernel the compiler just generate errors
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Here is the .config of my linux kernel :.
#

Hi Chen,
It looks like the kernel drivers you have built might have been using default platform configuration.
[ 226.710000] Mali<2>: mali_probe(): Called for platform device mali-utgard
[ 226.720000] Mali<2>: Using device defined memory settings (dedicated: 0x00000000@0x00000000, shared: 0x40000000)
[ 226.730000] Mali<2>: Using device defined frame buffer settings (0x00000000@0x00000000)
This won't build a working driver. It is necessary to use hardware OEM defined platform files specific to the platform you intend to run on (which ARM itself does not provide) to give the driver memory map regions etc.
The best starting point to do what you're doing is to take a working kernel tree for your target platform and replace the Mali drivers in the source with the ones you want to build; then to fix any mismatches between the mali driver version and kernel to get it building.
Hope this helps,
Rich
