Building mali-r5p0-01rel0 on linux-4.0.0-rc2-1-ARCH

[vitalogy]

Hi,

first ... thanks for your support to bring Arch Linux on ARM
I own a CubieTruck with a SSD connected, running linux-4.0.0-rc2-1-ARCH and it's working great.
CpuFreq is working fine with this kernel ... here are some hardware-stats:
$this->bbcode_second_pass_code('', 'Linux: 4.0.0-rc2-1-ARCH

But i can not build mali kernel-driver (downloaded from mali-hp)
Make the kernel-driver is failing with the following error:

So yes, the header-file sync.h is not on the system.
Has the sync.h something to do with the android staging-driver in linux-kernel?
And is it possible to build mali on this kernel at all?

I can't say that it was designed to be compiled against mainline.

Moinsen,

i could build the ump modul, and also the mali modul:
* by adding the following to the section _package-headers() in the PKBUILD from linux-armv7-rc
$this->bbcode_second_pass_code('', '
# google's sync implementation
mkdir -p "${pkgdir}/usr/lib/modules/${_kernver}/build/include/uapi"
cp drivers/staging/android/sync.h "${pkgdir}/usr/lib/modules/${_kernver}/build/include/"
cp drivers/staging/android/uapi/sync.h "${pkgdir}/usr/lib/modules/${_kernver}/build/include/uapi"')
* set CONFIG_SW_SYNC to yes in the kernel-config (do not know, if this is neccessary)
* rebuild and install linux-armv7-rc and linux-armv7-rc-headers

note: for building linux-armv7-rc i also had to modify the PKGBUILD to download direct linux-4.0-rc3, otherwise i got a package linux-armv7-rc-3.19.0 (??) and a error and break for the smileplug (dtb can not be found or so)

i had also to modify mali_sync.c to build successfully (found via google )
$this->bbcode_second_pass_code('', '
s32 mali_sync_fence_fd_alloc(struct sync_fence *sync_fence)
{
s32 fd = -1;

- fd = get_unused_fd();
+ fd = get_unused_fd_flags(0);
if (fd < 0) {
sync_fence_put(sync_fence);
return -1;
}
sync_fence_install(sync_fence, fd);

return fd;
}')


summary: i could load both modules
$this->bbcode_second_pass_code('', '[12035.953246] UMP: UMP device driver loaded
[12039.051604] Mali: Mali device driver loaded')

as my understanding, now i need the Mali GPU User Space Driver ... will see.
