- Move esp_devclass to ncr53c9x.c in order to allow different bus front-ends to use it. - Use KOBJMETHOD_END. - Remove the gl_clear_latched_intr hook as it's not needed for any of the chips nor the front-ends supported in FreeBSD and likely never will be. - Correct the DMA constraints used in the SBus front-end, the LSI64854 isn't limited to 32-bit DMA. - The ESP200 also only supports up to 64k transfers. - Don't let the DMA and SBus front-end supply a maximum transfer size larger than MAXPHYS as that's the maximum the upper layers use and we otherwise just waste resources unnecessarily. - Initialize the ECB callout and don't zero the handle when returning ECBs to the free list so that ncr53c9x_callout() actually is called with the driver lock held. - On detach the driver lock should be held across cam_sim_free() according to isp(4) and a panic received. - Check the return value of NCRDMA_SETUP(), i.e. bus_dmamap_load(9), and try to handle failures gracefully. - In ncr53c9x_action() replace N calls to xpt_done() in a switch with just one at the end. - On XPT_PATH_INQ report "NCR" rather than "Sun" as the vendor as the former is somewhat more correct as well as the maximum supported transfer size via maxio in order to take advantage of controllers that that can handle more than DFLTPHYS. - Print the number of MESSAGE (EXTENDED) rejected. - Fix the path encoded in the multiple inclusion protection of ncr53c9xvar.h. - Correct the DMA constraints used in the LSI64854 core to not exceed the maximum supported transfer size and include the boundary so we don't need to check on every setup of a DMA transfer. - Let the bus DMA map callbacks do nothing in case of an error. - Correctly handle > 64k transfers for FAS366 in the LSI64854. A new feature flag NCR_F_LARGEXFER was introduced so we just need to check for this one and not for individual controllers supporting large transfers in several places. - Let the LSI64854 core load transfer buffers using BUS_DMA_NOWAIT as the NCR53C9x core can't handle EINPROGRESS. Due to lack of bounce buffers support, sparc64 doesn't actually use EINPROGRESS and likely never will, as an example for writing additional front-ends for the NCR53C9x core it makes sense to set BUS_DMA_NOWAIT anyway though. - Some minor cleanup.
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
