[Letux-kernel] LetuxOS: Kernel: m-latest 5.9-rc1 successful

Tue Aug 18 19:53:38 CEST 2020

Trying out an LPAE build myself to see how it runs on the Pyra, I get a
failure in the mxc fbdev driver:

drivers/video/fbdev/mxc/mxc_epdc_v2_fb.c: In function
‘mxc_epdc_fb_fw_handler’:
drivers/video/fbdev/mxc/mxc_epdc_v2_fb.c:5853:7: error: passing
argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type [-
Werror=incompatible-pointer-types]
 5853 |       &fb_data->waveform_buffer_phys,
      |       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |       |
      |       u32 * {aka unsigned int *}
In file included from drivers/video/fbdev/mxc/mxc_epdc_v2_fb.c:44:
./include/linux/dma-mapping.h:534:15: note: expected ‘dma_addr_t *’
{aka ‘long long unsigned int *’} but argument is of type ‘u32 *’ {aka
‘unsigned int *’}
  534 |   dma_addr_t *dma_handle, gfp_t gfp)

and several like this.

It seems like it assumes that dma_addr_t === u32 which isn't true for
LPAE. 

As I don't care about i.MX I will just disable the driver in my
.config, but I think this is worth looking into if i.MX+LPAE is a
supported config in letux.

Best

David
