When we map the VBT through pci_map_rom() we may not be allowed to simply discard the address space and go on reading the memory. That doesn't work on my test system, but by dumping the rom via sysfs I can can get the correct vbt. So change our find_vbt() to do the same as done by pci_read_rom(), i.e. use memcpy_fromio(). v2: the just the minimal changes by not bothering with the unaligned io reads: this can be done on top (from Ville and Jani) v3: drop const in function return since now we are copying the vbt, rather than just finding it Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191126225110.8127-2-lucas.demarchi@intel.com
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
