Message-ID: <1329126268-11032-1-git-send-email-bill4carson@gmail.com> (raw)
Hi All
This is 2nd RFC PATCH for ARM huge page support. 2MB(two 1MB page)/16MB
huge page are supported, Versatile Express Cortex-A9x4 tile is used as test
board. Verification is done with libhugetlbfs with both arm/thumb2 instruction.
ChangeLog From V1:
- Drop L_PTE_HUGEPAGE defines
- Check whether super-section is supported through mmfr3
- Using mmu_context_t to store huge linux pte instead of mm_struct
Any suggestions would be truly welcome :)
Bill Carson(3)
- Add hugetlb high level hooks
- Using mmu_context_t to store huge linux pte
- Introduce set_hugepte_ext to set hardware pte
