Problems compiling kernel

Problems compiling kernel

[Ramón Finger Lilienthal]

Dear fellows,

I am facing some compiling errors in my kernel.

My kernel version is:

VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 27
EXTRAVERSION =
NAME = Rotary Wombat

And I updated the source using "git pull" today,  before trying to 
compile the kernel.

I got these errors:

  MODPOST vmlinux.o
  GEN     .version
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h
  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
arch/arm/plat-omap/built-in.o: In function `omap_verify_speed':
/home/ramon/work/linux-omap-2.6.new.teste/arch/arm/plat-omap/cpu-omap.c:46: 
undefined reference to `cpufreq_frequency_table_verify'
arch/arm/plat-omap/built-in.o: In function `omap_cpu_init':
/home/ramon/work/linux-omap-2.6.new.teste/arch/arm/plat-omap/cpu-omap.c:119: 
undefined reference to `cpufreq_frequency_table_cpuinfo'
/home/ramon/work/linux-omap-2.6.new.teste/arch/arm/plat-omap/cpu-omap.c:121: 
undefined reference to `cpufreq_frequency_table_get_attr'
arch/arm/plat-omap/built-in.o:(.data+0x91c): undefined reference to 
`cpufreq_freq_attr_scaling_available_freqs'
make: *** [.tmp_vmlinux1] Error 1

I looked in "plat-omap.c" and it calls the library cpufreq.h.
cpufreq.h has the prototipes of that undefined references and cpufreq.c 
has the impementations of it.

So, I don't understand why it is happening. By the way, I am a begginer 
in linux development.

Any help will be welcome.

RE: Problems compiling kernel

[Premi, Sanjeev]

Ramon,

Can you confirm if you have CONFIG_CPU_FREQ_TABLE=y in the .config?

The 'undefined' functions in your compile log are defined in drivers/cpufreq/freq_table.c
If you look at Makefile in the same dir, this file is included in compile based on the flag mentioned above.

Which platform are you building for?
Are you sure you haven't disabled CPU_FREQ manually?
If you haven't made any modifications the problem could be in the defconfig?

Though, I believe that cpu-omap.c may also need to be updated to take care of CONFIG_CPU_FREQ OR specifically CONFIG_CPU_FREQ_TABLE.

Best regards,
Sanjeev

Re: Problems compiling kernel

[Ramón Finger Lilienthal]

Dear Sanjeev,

Thanks for your help.

Now, I am building for omap5912osk, and we have a new board omap5912 
based.  I hope in some months changing my efforts to OMAP35.

Part of my .config file is listed below. The flag CONFIG_CPU_FREQ_TABLE 
was set to "m", I changed to "y". I tried to compile again, but the 
error still happening.
I took a look at .config after compiling and CONFIG_CPU_FREQ_TABLE got 
back to "m" (automatically).

==== .config  ===
#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=m
# CONFIG_CPU_FREQ_DEBUG is not set
CONFIG_CPU_FREQ_STAT=m
CONFIG_CPU_FREQ_STAT_DETAILS=y
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=m
CONFIG_CPU_FREQ_GOV_ONDEMAND=m
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m

#
=============

After, i changed the flags CONFIG_CPU_FREQ_TABLE=y and 
CONFIG_CPU_FREQ_STAT=y.
Then that error didn't occurred again, but another error happened:

====
  CHK     include/linux/compile.h
  CC [M]  drivers/net/b44.o
  Kernel: arch/arm/boot/Image is ready
  LD      arch/arm/boot/compressed/vmlinux

Again, thanks for your help

Did you change this driver?

I did not see this problem on my working branch based off tag v2.6.26-omap2.
(I built for omap_osk_5912_defconfig)

However, I do see many section mismatches:

WARNING: arch/arm/mach-omap1/built-in.o(.data+0x26c): Section mismatch in reference from the variable omap1_clk_functions to the function .init.text:omap1_clk_disable_unused()
The variable omap1_clk_functions references
the function __init omap1_clk_disable_unused()
If the reference is valid then annotate the
variable with __init* (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,

  LD      vmlinux.o
  MODPOST vmlinux.o
WARNING: vmlinux.o(.text+0x2a68): Section mismatch in reference from the function cpu_init() to the function .init.text:dump_cpu_info()
The function cpu_init() references
the function __init dump_cpu_info().
This is often because cpu_init lacks a __init
annotation or the annotation of dump_cpu_info is wrong.

WARNING: vmlinux.o(.text+0x14af74): Section mismatch in reference from the function smc_drv_probe() to the function .init.text:smc_probe()
The function smc_drv_probe() references
the function __init smc_probe().
This is often because smc_drv_probe lacks a __init
annotation or the annotation of smc_probe is wrong.

WARNING: vmlinux.o(.data+0x14dc): Section mismatch in reference from the variable omap1_clk_functions to the function .init.text:omap1_clk_disable_unused()

If the reference is valid then annotate the
variable with __init* (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,
