      drm/vc4: Correct lbm size and calculation · 78e53303
      Dom Cobley authored
      LBM base address is measured in units of pixels per cycle.
      That is 4 for 2711 (hvs5) and 2 for 2708.
      
      We are wasting 75% of lbm by indexing without the scaling.
      But we were also using too high a size for the lbm resulting
      in partial corruption (right hand side) of vertically
      scaled images, usually at 4K or lower resolutions with more layers.
      
      The physical RAM of LBM on 2711 is 8 * 1920 * 16 * 12-bit
      (pixels are stored 12-bits per component regardless of format).
      
      The LBM address indexes work in units of pixels per clock,
      so for 4 pixels per clock that means we have 32 * 1920 = 60K

      The K: entry should ensure that Nick and I always get CC'd on patches that
      touch these files but it is better to be explicit rather than implicit.

      proc_sysctl: fix oops caused by incorrect command parameters · 697edcb0
      Xiaoming Ni authored
      The process_sysctl_arg() does not check whether val is empty before
      invoking strlen(val).  If the command line parameter () is incorrectly
      configured and val is empty, oops is triggered.
      
      For example:
        "hung_task_panic=1" is incorrectly written as "hung_task_panic", oops is
        triggered. The call stack is as follows:
          Kernel command line: .... hung_task_panic
          ......
          Call trace:
          __pi_strlen+0x10/0x98
          parse_args+0x278/0x344
          do_sysctl_args+0x8c/0xfc
          kernel_init+0x5c/0xf4
          ret_from_fork+0x10/0x30
      
      To fix it, check whether "val" is empty when "phram" is a sysctl field.
      Error codes are returned in the failure branch, and error logs are
      generated by parse_args().
