      drm/tegra: drop "select DRM_HDMI" · 36c1813b
      Paul Bolle authored
      Commit ac24c220
      
       ("drm/tegra: Use generic
      HDMI infoframe helpers") added "select DRM_HDMI" to the DRM_TEGRA
      Kconfig entry. But there is no Kconfig symbol named DRM_HDMI. The select
      statement for that symbol is a nop. Drop it.
      
      What was needed to use HDMI functionality was to select HDMI (which this
      entry already did through depending on DRM) and to include linux/hdmi.h
      (which this commit also did).

      drm/mgag200: Bug fix: Renesas board now selects native resolution. · ce495960
      Julia Lemire authored
      
      
      Renesas boards were consistently defaulting to the 1024x768 resolution,
      regardless of the native resolution of the monitor plugged in.  It was
      determined that the EDID of the monitor was not being read.  Since the
      DAC is a shared line, in order to read from or write to it we must take
      control of the DAC clock.  This can be done by setting the proper
      register to one.
      
      This bug fix sets the register MGA1064_GEN_IO_CTL2 to one.  The DAC
      control line can be used to determine whether or not a new monitor has
      been plugged in.  But since the hotplug feature is not one we will
      support, it has been decided to simply leave the register set to one.

      drm/mgag200: Reject modes that are too big for VRAM · 0ba53171
      Christopher Harvey authored
      
      
      A monitor or a user could request a resolution greater than the
      available VRAM for the backing framebuffer. This change checks the
      required framebuffer size against the max VRAM size and rejects modes
      if they are too big. This change can also remove a mode request passed
      in via the video= parameter.

      x86: Do not try to sync identity map for non-mapped pages · 60f583d5
      Dave Hansen authored
      kernel_map_sync_memtype() is called from a variety of contexts.  The
      pat.c code that calls it seems to ensure that it is not called for
      non-ram areas by checking via pat_pagerange_is_ram().  It is important
      that it only be called on the actual identity map because there *IS*
      no map to sync for highmem pages, or for memory holes.
      
      The ioremap.c uses are not as careful as those from pat.c, and call
      kernel_map_sync_memtype() on PCI space which is in the middle of the
      kernel identity map _range_, but is not actually mapped.
      
      This patch adds a check to kernel_map_sync_memtype() which probably
      duplicates some of the checks already in pat.c.  But, it is necessary
      for the ioremap.c uses and shouldn't hurt other callers.
      
      I have reproduced this bug and this patch fixes it for me and the
      original bug reporter:

      drm/radeon: don't check mipmap alignment if MIP_ADDRESS is FMASK · 774c389f
      Marek Olšák authored
      
      
      The MIP_ADDRESS state has 2 meanings. If the texture has one sample
      per pixel, it's a pointer to the mipmap chain. If the texture has
      multiple samples per pixel, it's a pointer to FMASK, a metadata buffer
      needed for reading compressed MSAA textures. The mipmap
      alignment rules do not apply to FMASK.
