      powerpc/85xx: Load all early TLB entries at once · d9e1831a
      Scott Wood 提交于
      Use an AS=1 trampoline TLB entry to allow all normal TLB1 entries to
      be loaded at once.  This avoids the need to keep the translation that
      code is executing from in the same TLB entry in the final TLB
      configuration as during early boot, which in turn is helpful for
      relocatable kernels (e.g. kdump) where the kernel is not running from
      what would be the first TLB entry.
      
      On e6500, we limit map_mem_in_cams() to the primary hwthread of a
      core (the boot cpu is always considered primary, as a kdump kernel
      can be entered on any cpu).  Each TLB only needs to be set up once,
      and when we do, we don't want another thread to be running when we
      create a temporary trampoline TLB1 entry.

      powerpc/fsl_booke: smp support for booting a relocatable kernel above 64M · 0be7d969
      Kevin Hao 提交于
      When booting above the 64M for a secondary cpu, we also face the
      same issue as the boot cpu that the PAGE_OFFSET map two different
      physical address for the init tlb and the final map. So we have to use
      switch_to_as1/restore_to_as0 between the conversion of these two
      maps. When restoring to as0 for a secondary cpu, we only need to
      return to the caller. So add a new parameter for function
      restore_to_as0 for this purpose.
      
      Use LOAD_REG_ADDR_PIC to get the address of variables which may
      be used before we set the final map in cams for the secondary cpu.
      Move the setting of cams a bit earlier in order to avoid the
      unnecessary using of LOAD_REG_ADDR_PIC.

      powerpc/fsl-booke64: Use TLB CAMs to cover linear mapping on FSL 64-bit chips · 55fd766b
      Kumar Gala 提交于
      On Freescale parts typically have TLB array for large mappings that we can
      bolt the linear mapping into.  We utilize the code that already exists
      on PPC32 on the 64-bit side to setup the linear mapping to be cover by
      bolted TLB entries.  We utilize a quarter of the variable size TLB array
      for this purpose.
      
      Additionally, we limit the amount of memory to what we can cover via
      bolted entries so we don't get secondary faults in the TLB miss
      handlers.  We should fix this limitation in the future.
