  1. amd-gpu: correct sharedmem allocation

    Matt Sealey authored
    Merge/tree mishap caused this code to go missing.

  2. amd-gpu: remove aperture concept from the memory manager

    Matt Sealey authored
    Now everything is one big memarena instead of a separate PHYS and EMEM,
    and instead of having to micromanage the split between Z160 (always PHYS
    here) and GPU (99% of it's allocations come out of EMEM), we give blocks
    from the same memory pool.
    
    This should effect some more efficient allocation strategies and allow
    Xorg acceleration to proceed with much less movement of data (when it
    evicts for low memory in PHYS, it moves it to userspace and uses pixman
    to render everything, which is CPU intensive) at the potential cost of
    leaving slightly less memory around for the 3D GPU, but userspace apps
    using the GPU should be doing better with texture management so as not
    to soak up >32MiB of reserved GPU memory needlessly.
    
    Moving away from gsl_memmgr to genalloc is not desirable right now since
    the driver requires multiple allocation alignment orders and genalloc can
    only really guarantee a minimum alignment (i.e. size of allocation
    represented by each bit in the allocation bitmap).
    
    Moving to a dma_alloc_coherent/writecombine-only model also poses a
    problem since significant amounts of code expects to be able to find the
    "base" GPU memory address and with individual allocations instead of a
    pooled area, there is no such thing.

    amd-gpu: rework apertures

    ahmedammar authored
    * increase from 64MB to 96MB total memory
    * after some testing it seems that PHYS can be quite small compared
      to EMEM, therefore make the aperture split 16MB/80MB

  1. Revert "ARM 5784/1 fix early boot machine ID mismatch error display"

    Matt Sealey authored
    Mistakenly applied this to 2.6.31 all those years ago while doing
    experiments on later kernels. Actually it depends on several other
    patches which never got applied.
    
    This reverts commit 9dda27b.

  5. font: add the Fixed 8x16 console font to the kernel.

    Matt Sealey authored
    It's a bit like Terminus, but more rounded and less harsh on the eyes. Ubuntu has shipped
    it as their default console font for years, before they switched to the "Ubuntu" font. Putting
    this in the kernel has practically no benefit except to reduce the amount of "glitching"
    swapping the built-in kernel console font for a new one halfway through boot when you see the
    kernel output on a screen.
    
    Note to gain the benefit of it not swapping the font around again when "consolefont" or
    similar service starts, you need to set your font to Uni3-Fixed16.psf.gz or something very
    similar.

  7. ENGR00160722 amd gpu: add best fit algorithm to memory manager

    Xinyu Chen authored Matt Sealey committed
    The AMD gpu driver memory manager is stupid to allocating
    a memory block from the first free block. Neither check the
    best fit free block. Here just add a little codes to
    let allocation to find a best size fitted free block.
    To avoid memory fragement.

    Makes sense (and is from Qualcomm's driver) since we cannot guarantee
