      ARC: Ignore ptrace SETREGSET request for synthetic register "stop_pc" · 5b242828
      Vineet Gupta 提交于
      ARCompact TRAP_S insn used for breakpoints, commits before exception is
      taken (updating architectural PC). So ptregs->ret contains next-PC and
      not the breakpoint PC itself. This is different from other restartable
      exceptions such as TLB Miss where ptregs->ret has exact faulting PC.
      gdb needs to know exact-PC hence ARC ptrace GETREGSET provides for
      @stop_pc which returns ptregs->ret vs. EFA depending on the
      situation.
      
      However, writing stop_pc (SETREGSET request), which updates ptregs->ret
      doesn't makes sense stop_pc doesn't always correspond to that reg as
      described above.
      
      This was not an issue so far since user_regs->ret / user_regs->stop_pc
      had same value and both writing to ptregs->ret was OK, needless, but NOT
      broken, hence not observed.
      
      With gdb "jump", they diverge, and user_regs->ret updating ptregs is
      overwritten immediately with stop_pc, which this patch fixes.

        And one pain in the ass revert, so we have VGA arbitration that when
        implemented 4-5 years ago really hoped that GPUs could remove
        themselves from arbitration completely once they had a kernel driver.
      
        It seems Intel hw designers decided that was too nice a facility to
        allow us to have so they removed it when they went on-die (so since
        Ironlake at least).  Now Alex Williamson added support for VGA
        arbitration for newer GPUs however this now exposes itself to
        userspace as requireing arbitration of GPU VGA regions and the X
        server gets involved and disables things that it can't handle when VGA
        access is possibly required around every operation.
      
        So in order to not break userspace we just reverted things back to the
        old known broken status so maybe we can try and design out way out.
      
        Ville also had a patch to use stop machine for the two times Intel
        needs to access VGA space, that might be acceptable with some rework,
        but for now myself and Daniel agreed to just go back"
