2006-04-11[PATCH] Configurable NODES_SHIFTYasunori Goto2-28/+0
Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.

Patch from Lennert Buytenhek The debug-8250 macros do byte accesses, which means that if we're in big-endian mode, we need to logically OR the UART address with 3, as the LSB byte lane (where UART data and status is transferred) has the highest byte address in the word when we are in big-endian mode.

2006-04-04[ARM] arm's arch_local_page_offset() fix against 2.6.17-rc1KAMEZAWA Hiroyuki1-1/+1
This patch fixes arch_local_page_offset(pfn,nid) in arm. This new one (added by unify_pfn_to_page patches) is obviously buggy. This macro calculate page offset in a node. Note: about LOCAL_MAP_NR() comment in arm's sub-archs says... /* * Given a kaddr, LOCAL_MAP_NR finds the owning node of the memory * and returns the index corresponding to the appropriate page in the * node's mem_map. */ but LOCAL_MAP_NR() is designed to be able to take both paddr and kaddr. In this case, paddr is better. Signed-off-by: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitu.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-04-02[ARM] 3457/1: i.MX: SD/MMC support for i.MX/MX1Pavel Pisa1-0/+12
Patch from Pavel Pisa This patch adds support of i.MX/MX1 SD/MMC controller. It has been significantly redesigned from the original Sascha Hauer's version to support scatter-gather DMA, to conform to latest Pierre Ossman's and Russell King's MMC-SD Linux 2.6.x infrastructure. The handling of all events has been moved to the softirq context and is designed with no busy-looping in mind. Unfortunately some controller bugs has to be overcome by limited looping about 2-20 usec but these are observed only for initial card recognition phase. There are still some missing/missed IRQs problems under heavy load. Help of somebody with access to the full SDHC design information is probably necessary. Regenerated against 2.6.16-git-060402 to solve clash with other patches.

2006-04-02[ARM] 3439/2: xsc3: add I/O coherency supportLennert Buytenhek5-7/+42
Patch from Lennert Buytenhek This patch adds support for the I/O coherent cache available on the xsc3. The approach is to provide a simple API to determine whether the chipset supports coherency by calling arch_is_coherent() and then setting the appropriate system memory PTE and PMD bits. In addition, we call this API on dma_alloc_coherent() and dma_map_single() calls. A generic version exists that will compile out all the coherency-related code that is not needed on the majority of ARM systems. Note that we do not check for coherency in the dma_alloc_writecombine() function as that still requires a special PTE setting. We also don't touch dma_mmap_coherent() as that is a special ARM-only API that is by definition only used on non-coherent system.

Patch from Lennert Buytenhek On the Double Espresso board, the IXP2350s are PCI slave devices and we skip calling pci_common_init() as that enumerates the bus. But even though we are a PCI slave device, there is still some PCI-related setup that has to be done. Create ixp23xx_pci_common_init(), move the common initialisation bits there, and have this function called from both the PCI master and the PCI slave init path.

Patch from Lennert Buytenhek This patch adds support for the new XScale v3 core. This is an ARMv5 ISA core with the following additions: - L2 cache - I/O coherency support (on select chipsets) - Low-Locality Reference cache attributes (replaces mini-cache) - Supersections (v6 compatible) - 36-bit addressing (v6 compatible) - Single instruction cache line clean/invalidate - LRU cache replacement (vs round-robin) I attempted to merge the XSC3 support into proc-xscale.S, but XSC3 cores have separate errata and have to handle things like L2, so it is simpler to keep it separate. L2 cache support is currently a build option because the L2 enable bit must be set before we enable the MMU and there is no easy way to capture command line parameters at this point. There are still optimizations that can be done such as using LLR for copypage (in theory using the exisiting mini-cache code) but those can be addressed down the road.

2006-03-26[ARM] 3414/1: ep93xx: reset ethernet controller before uncompressingLennert Buytenhek1-1/+39
Patch from Lennert Buytenhek The Redboot version that cirrus supplies for the cirrus ep93xx doesn't turn off DMA from the ethernet MAC before jumping to linux, which means that we might end up with bits of RX status and packet data scribbled over the uncompressed kernel image. Work around this by resetting the ethernet MAC before we uncompress. We don't usually work around bootloader bugs, but considering that the large majority of ep93xx boards out there have this problem, I figured this it was justified in this case.

2006-03-25[PATCH] POLLRDHUP/EPOLLRDHUP handling for half-closed devices notificationsDavide Libenzi1-0/+1
Implement the half-closed devices notifiation, by adding a new POLLRDHUP (and its alias EPOLLRDHUP) bit to the existing poll/select sets. Since the existing POLLHUP handling, that does not report correctly half-closed devices, was feared to be changed, this implementation leaves the current POLLHUP reporting unchanged and simply add a new bit that is set in the few places where it makes sense. The same thing was discussed and conceptually agreed quite some time ago: http://lkml.org/lkml/2003/7/12/116 Since this new event bit is added to the existing Linux poll infrastruture, even the existing poll/select system calls will be able to use it. As far as the existing POLLHUP handling, the patch leaves it as is. The pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing archs and sets the bit in the six relevant files. The other attached diff is the simple change required to sys/epoll.h to add the EPOLLRDHUP definition. There is "a stupid program" to test POLLRDHUP delivery here: http://www.xmailserver.org/pollrdhup-test.c It tests poll(2), but since the delivery is same epoll(2) will work equally.
