      arm64: Enable TEXT_OFFSET fuzzing · da57a369
      Mark Rutland authored
      The arm64 Image header contains a text_offset field which bootloaders
      are supposed to read to determine the offset (from a 2MB aligned "start
      of memory" per booting.txt) at which to load the kernel. The offset is
      not well respected by bootloaders at present, and due to the lack of
      variation there is little incentive to support it. This is unfortunate
      for the sake of future kernels where we may wish to vary the text offset
      (even zeroing it).
      
      This patch adds options to arm64 to enable fuzz-testing of text_offset.
      CONFIG_ARM64_RANDOMIZE_TEXT_OFFSET forces the text offset to a random
      16-byte aligned value value in the range [0..2MB) upon a build of the
      kernel. It is recommended that distribution kernels enable randomization
      to test bootloaders such that any compliance issues can be fixed early.

      arm64: Update the Image header · a2c1d73b
      Mark Rutland authored
      Currently the kernel Image is stripped of everything past the initial
      stack, and at runtime the memory is initialised and used by the kernel.
      This makes the effective minimum memory footprint of the kernel larger
      than the size of the loaded binary, though bootloaders have no mechanism
      to identify how large this minimum memory footprint is. This makes it
      difficult to choose safe locations to place both the kernel and other
      binaries required at boot (DTB, initrd, etc), such that the kernel won't
      clobber said binaries or other reserved memory during initialisation.
      
      Additionally when big endian support was added the image load offset was
      overlooked, and is currently of an arbitrary endianness, which makes it
      difficult for bootloaders to make use of it. It seems that bootloaders
      aren't respecting the image load offset at present anyway, and are
      assuming that offset 0x80000 will always be correct.
      
      This patch adds an effective image size to the kernel header which
      describes the amount of memory from the start of the kernel Image binary
      which the kernel expects to use before detecting memory and handling any
      memory reservations. This can be used by bootloaders to choose suitable
      locations to load the kernel and/or other binaries such that the kernel
      will not clobber any memory unexpectedly. As before, memory reservations
      are required to prevent the kernel from clobbering these locations
      later.
      
      Both the image load offset and the effective image size are forced to be
      little-endian regardless of the native endianness of the kernel to
      enable bootloaders to load a kernel of arbitrary endianness. Bootloaders
      which wish to make use of the load offset can inspect the effective
      image size field for a non-zero value to determine if the offset is of a
      known endianness. To enable software to determine the endinanness of the
      kernel as may be required for certain use-cases, a new flags field (also
      little-endian) is added to the kernel header to export this information.
      
      The documentation is updated to clarify these details. To discourage
      future assumptions regarding the value of text_offset, the value at this
      point in time is removed from the main flow of the documentation (though
      kept as a compatibility note). Some minor formatting issues in the
      documentation are also corrected.

      arm64: place initial page tables above the kernel · bd00cd5f
      Mark Rutland authored
      Currently we place swapper_pg_dir and idmap_pg_dir below the kernel
      image, between PHYS_OFFSET and (PHYS_OFFSET + TEXT_OFFSET). However,
      bootloaders may use portions of this memory below the kernel and we do
      not parse the memory reservation list until after the MMU has been
      enabled. As such we may clobber some memory a bootloader wishes to have
      preserved.
      
      To enable the use of all of this memory by bootloaders (when the
      required memory reservations are communicated to the kernel) it is
      necessary to move our initial page tables elsewhere. As we currently
      have an effectively unbound requirement for memory at the end of the
      kernel image for .bss, we can place the page tables here.
      
      This patch moves the initial page table to the end of the kernel image,
      after the BSS. As they do not consist of any initialised data they will
      be stripped from the kernel Image as with the BSS. The BSS clearing
      routine is updated to stop at __bss_stop rather than _end so as to not
      clobber the page tables, and memory reservations made redundant by the
      new organisation are removed.

      arm64: head.S: remove unnecessary function alignment · 909a4069
      Mark Rutland authored
      Currently __turn_mmu_on is aligned to 64 bytes to ensure that it doesn't
      span any page boundary, which simplifies the idmap and spares us
      requiring an additional page table to map half of the function. In
      keeping with other important requirements in architecture code, this
      fact is undocumented.
      
      Additionally, as the function consists of three instructions totalling
      12 bytes with no literal pool data, a smaller alignment of 16 bytes
      would be sufficient.
      
      This patch reduces the alignment to 16 bytes and documents the
      underlying reason for the alignment. This reduces the required alignment
      of the entire .head.text section from 64 bytes to 16 bytes, though it
      may still be aligned to a larger value depending on TEXT_OFFSET.

      arm64: enable context tracking · 6c81fe79
      Larry Bassel authored
      Make calls to ct_user_enter when the kernel is exited
      and ct_user_exit when the kernel is entered (in el0_da,
      el0_ia, el0_svc, el0_irq and all of the "error" paths).
      
      These macros expand to function calls which will only work
      properly if el0_sync and related code has been rearranged
      (in a previous patch of this series).
      
      The calls to ct_user_exit are made after hw debugging has been
      enabled (enable_dbg_and_irq).
      
      The call to ct_user_enter is made at the beginning of the
      kernel_exit macro.
      
      This patch is based on earlier work by Kevin Hilman.
      Save/restore optimizations were also done by Kevin.

      arm64: adjust el0_sync so that a function can be called · 6ab6463a
      Larry Bassel authored
      To implement the context tracker properly on arm64,
      a function call needs to be made after debugging and
      interrupts are turned on, but before the lr is changed
      to point to ret_to_user(). If the function call
      is made after the lr is changed the function will not
      return to the correct place.
      
      For similar reasons, defer the setting of x0 so that
      it doesn't need to be saved around the function call
      (save far_el1 in x26 temporarily instead).

      arm64: fix el2_setup check of CurrentEL · 974c8e45
      Marc Zyngier authored
      The CurrentEL system register reports the Current Exception Level
      of the CPU. It doesn't say anything about the stack handling, and
      yet we compare it to PSR_MODE_EL2t and PSR_MODE_EL2h.
      
      It works by chance because PSR_MODE_EL2t happens to match the right
      bits, but that's otherwise a very bad idea. Just check for the EL
      value instead.

      arm64: mm: Make icache synchronisation logic huge page aware · 923b8f50
      Steve Capper authored
      The __sync_icache_dcache routine will only flush the dcache for the
      first page of a compound page, potentially leading to stale icache
      data residing further on in a hugetlb page.
      
      This patch addresses this issue by taking into consideration the
      order of the page when flushing the dcache.

      ALSA: hda - restore BCLK M/N value as per CDCLK for HSW/BDW display HDA controller · e4d9e513
      Mengdong Lin authored
      For HSW/BDW display HD-A controller, hda_set_bclk() is defined to set BCLK
      by programming the M/N values as per the core display clock (CDCLK) queried from
      i915 display driver.
      
      And the audio driver will also set BCLK in azx_first_init() since the display
      driver can turn off the shared power in boot phase if only eDP is connected
      and M/N values will be lost and must be reprogrammed.

      drm/i915: provide interface for audio driver to query cdclk · c149dcb5
      Jani Nikula authored
      For Haswell and Broadwell, if the display power well has been disabled,
      the display audio controller divider values EM4 M VALUE and EM5 N VALUE
      will have been lost. The CDCLK frequency is required for reprogramming them
      to generate 24MHz HD-A link BCLK. So provide a private interface for the
      audio driver to query CDCLK.
      
      This is a stopgap solution until a more generic interface between audio
      and display drivers has been implemented.
