Message-Id: <201204062059.q36KxjEO011317@farm-0027.internal.tilera.com> Date: Wed, 4 Apr 2012 16:39:58 -0400 From: Chris Metcalf <cmetcalf@...era.com> To: linux-kernel@...r.kernel.org, netdev@...r.kernel.org Subject: [PATCH 0/6] arch/tile: provide tilegx networking support This change set provides support for the on-chip networking hardware on the TILE-Gx chip. The actual network driver is layered on top of the mPIPE hardware support, which is layered on top of the GXIO IORPC facility (and its DMA layer). The change set breaks this down into a series of patches, each progressively adding another component of functionality. There are also a couple of simple changes to add support for MMIO memory mappings for readb/writeb, and for installing MMIO PTEs, which are necessary for this change. arch/tile/Kconfig | 2 + arch/tile/Makefile | 1 + arch/tile/gxio/Kconfig | 25 + arch/tile/gxio/Makefile | 7 + arch/tile/gxio/dma_queue.c | 236 ++++ arch/tile/gxio/iorpc_globals.c | 102 ++ arch/tile/gxio/iorpc_mpipe.c | 571 ++++++++ arch/tile/gxio/iorpc_mpipe_info.c | 95 ++ arch/tile/gxio/kiorpc.c | 60 + arch/tile/gxio/mpipe.c | 631 +++++++++ arch/tile/include/arch/mpipe.h | 321 +++++ arch/tile/include/arch/mpipe_constants.h | 43 + arch/tile/include/arch/mpipe_def.h | 39 + arch/tile/include/arch/mpipe_shm.h | 421 ++++++ arch/tile/include/arch/mpipe_shm_def.h | 23 + arch/tile/include/asm/io.h | 110 ++- arch/tile/include/gxio/common.h | 40 + arch/tile/include/gxio/dma_queue.h | 59 + arch/tile/include/gxio/iorpc_globals.h | 38 + arch/tile/include/gxio/iorpc_mpipe.h | 124 ++ arch/tile/include/gxio/iorpc_mpipe_info.h | 46 + arch/tile/include/gxio/kiorpc.h | 29 + arch/tile/include/gxio/mpipe.h | 1986 ++++++++++++++++++++++++++++ arch/tile/include/hv/drv_mpipe_intf.h | 602 +++++++++ arch/tile/include/hv/iorpc.h | 716 ++++++++++ arch/tile/mm/pgtable.c | 16 +- drivers/net/ethernet/tile/Kconfig | 1 + drivers/net/ethernet/tile/Makefile | 4 +- drivers/net/ethernet/tile/tilegx.c | 2045 +++++++++++++++++++++++++++++ 29 files changed, 8359 insertions(+), 34 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
