BGE_PCI_PCISTATE register before issuing global reset. After issuing reset, it reads BGE_PCI_PCISTATE register again and compares the saved register value and current value. It was used to know whether the global reset operation was completed or not. Unfortunately, this logic caused several issues on recent BCM5717/ 5718/5719 and BCM5720 controllers. It seems APE firmware accesses some registers while global reset is in progress such that reading BGE_PCI_PCISTATE register after reset does not yield old pre-reset state value. This resulted in consuming too much time in global reset and sometimes it couldn't successfully complete reset. The BGE_MISCCFG_RESET_CORE_CLOCKS of BGE_MISC_CFG register is self-clearing bit so driver is able to know the reset completion. But the core-lock reset will disable indirect/flat/standard access modes such that driver cannot poll BGE_MISCCFG_RESET_CORE_CLOCKS bit of BGE_MISC_CFG register. So just wait enough time for core-clock reset to complete. Data sheet says driver should wait 100us for PCI/PCI-X devices and 100ms for PCIe devices. I chose 1ms for PCI/PCI-X since this value was used for many years in bge(4). For PCIe devices, use 100ms as recommended by data sheet. bge_chipinit() also cleared BGE_MAC_MODE register which shall clear firmware configured mode information. I think this will result in losing ASF/IPMI link in device attachment. Let bge_reset() honor firmware configured BGE_MAC_MODE register and don't announce driver is UP in bge_reset(). Firmware should have control over driver until it's fully initialized by driver. While I'm here, enable workaround for PCI-X BCM5704 A0 in bge_reset(). This will prevent internal arbitration logic from switching to the other DMA engine after a retry cycle. |

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.
