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 :.
#

Hello chen,
and welcome on the Arm connected community
At first glance you are missing a variable definition file (maybe "mali_osk.h"). But is it can be a bad use of the compiler.
Can you tell us more about your environment and the equipment you use ?
Hi Chen,
The problem is that the sources showing issues such as mali_osk_misc.c are in multiple places; mali/ and ump/.
It is necessary to build ump.ko first, and THEN build mali.ko as mali.ko will attempt to link against ump.ko if UMP support is enabled.
This should help solve the issue.
Hope this helps!
Rich
Thanks ,Jerome
My host is ubuntu 14.0 32bit, and my toolchain is gcc version 4.5.1 (ctng-1.8.1-FA) .and I also tried the gcc gcc version 4.8.1 which met the same problem when I compiled the kernel drivers.
I keep the original structure of mali 400 kernel drivers files .
+gpu/mali_r4p0-00rel1/
+--mali/
+--ump/
+--umplock/
I just rename the file of `src` with `mali_r4p0-00rel1`, And I add the the Kconfig and the Makefile to point the directory of `mali` and the `ump`.`
The $KDIR/drivers/gpu/Makefile and the $KDIR/drivers/gpu/Kconfig just are the following.
The Makefile is :
--------------------------------------------------------------------------------------------
obj-$(CONFIG_MALI400)+= mali_r4p0-00rel1/devicedrv/mali
obj-$(CONFIG_UMP)+= mali_r4p0-00rel1/devicedrv/ump
The Kconfig is :
source "drivers/gpu/mali_r4p0-00rel1/devicedrv/mali/Kconfig"
source "drivers/gpu/mali_r4p0-00rel1/devicedrv/ump/Kconfig"
regards
Larry Chen
Thank you,Rich
But when I compiled them to Modules to insert the kernel , I got following errors:
--------------------------------------------------------------------------------------------------------------

And do you know how to compile the Mali drivers into the kernel ?
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,
