Re: cannot insmod sculld in ldd3
Hello, Freeman Zhang. copying 'Module.symvers' to sculld folder solved the problem. Thank you, man. Now I wonder what is the proper way to export "Module.symvers" information to the outside so that modules that use it do not have to copy that file into their directory. for example, what do pci and usb buses do in this case? ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

question about nopage sample code
in ldd3 no page is implemented as the code posted below (page 428).
can someone explain why should we subtract vma->vm_start?
struct page *simple_vma_nopage(struct vm_area_struct *vma,
unsigned long address, int *type)
{
struct page *pageptr;
unsigned long offset = vma->vm_pgoff << PAGE_SHIFT;
unsigned long physaddr = address - vma->vm_start + offset; // why
should we subtract vma->vm_start ?
unsigned long pageframe = physaddr >> PAGE_SHIFT;
if (!pfn_valid(pageframe))
return NOPAGE_SIGBUS;
pageptr = pfn_to_page(pageframe);
get_page(pageptr);
if (type)
*type = VM_FAULT_MINOR;
return pageptr;
}
thank you
Ali Aminian.

Re: Why amdgpu pro does not work on kernel 4.10?
Hello again. I just find out something weird. 1_ I typed make menuconfig 2_ I went to "general setup" and unchecked "Automatically append version information to the version string" 3_ recompiled and installed the new kernel and suddenly all problems are disappeared. I am wondering why this option causes problems. ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
Re: Why amdgpu pro does not work on kernel 4.10?
Thank you for your response. It does not work means: 1_ I have downloaded amdgpu-pro driver from AMD website and installed it. 2_ I have compiled linux kernel 4.10 and 4.9 with oldconfig. 3_ then I booted to new kernel and see login screen is distorted. 4_ I tried to login but it loops back to login screen again. 5_ Ctrl Alt F1-F6 results in a blank screen. 6_ I sshed into the system and check if amdgpu is loaded by "lsmod | grep amd" and yes it is loaded. 7_ I uninstalled and installed amdgpu-pro again and i got dkms error and it refered me to /var/lib/dkms/amdgpu-pro/16.40-348864/build/make.log for further details. and here is the log file: DKMS make.log for amdgpu-pro-14.40-348864 for kernel 4.10.0-rc7+ (x86_64) Mon Feb 13 03:53:09 IRST 2017 LD /var/lib/dkms/amdgpu-pro/16.40-348864/build/built-in.o LD /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/built-in.o CC [M] /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/amdgpu_drv.o In file included from /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/../backport/backport.h:8:0, from :0: /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/../backport/include/kcl/kcl_drm.h:68:72: error: operator '+' has no right operand && LINUX_VERSION_CODE < KERNEL_VERSION(4, 3, 0) && (UBUNTU_BUILD_NUM < 36)) \ ^ In file included from /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/../backport/backport.h:9:0, from :0: /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/../backport/include/kcl/kcl_ttm.h: In function ‘kcl_ttm_bo_reserve’: /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/../backport/include/kcl/kcl_ttm.h:109:9: error: too many arguments to function ‘ttm_bo_reserve’ return ttm_bo_reserve(bo, interruptible, no_wait, false, ticket); ^ In file included from /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/../backport/include/kcl/kcl_ttm.h:6:0, from /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/../backport/backport.h:9, from :0: ./include/drm/ttm/ttm_bo_driver.h:875:19: note: declared here static inline int ttm_bo_reserve(struct ttm_buffer_object *bo, ^ In file included from /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/../backport/include/kcl/kcl_amdgpu.h:5:0, from /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/../backport/backport.h:10, from :0: /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/../amdgpu/amdgpu.h: At top level: /var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/../amdgpu/amdgpu.h:37:25: fatal error: linux/fence.h: No such file or directory compilation terminated. scripts/Makefile.build:294: recipe for target '/var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/amdgpu_drv.o' failed make[4]: *** [/var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu/amdgpu_drv.o] Error 1 scripts/Makefile.build:553: recipe for target '/var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu' failed make[3]: *** [/var/lib/dkms/amdgpu-pro/16.40-348864/build/amd/amdgpu] Error 2 Makefile:1490: recipe for target '_module_/var/lib/dkms/amdgpu-pro/16.40-348864/build' failed make[2]: *** [_module_/var/lib/dkms/amdgpu-pro/16.40-348864/build] Error 2 ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
Why amdgpu pro does not work on kernel 4.10?
I was heard that amdgpu pro is user space driver and the kernel space part (amdgpu) is merged into Linux kernel. And that means amdgpu pro should work on all kernels above 4.3. But why amdgpu pro does not work on kernel 4.10? ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
