| * A while back, the array of segments used for a load/mapping operation wasIan Lepore2014-07-291-68/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | moved from the stack into the tag structure. In retrospect that was a bad idea, because nothing protects that array from concurrent access by multiple threads. This change moves the array to the map structure (actually it's allocated following the structure, but all in a single malloc() call). This also establishes a "sane" limit of 4096 segments per map. This is mostly to prevent trying to allocate all of memory if someone accidentally uses a tag with nsegments set to BUS_SPACE_UNRESTRICTED. If there's ever a genuine need for more than 4096, don't hesitate to increase this (or maybe make it tunable). Reviewed by: cognet Notes: svn path=/head/; revision=269216

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | triggers a need to bounce due to cacheline alignment. These buffers are always aligned to cacheline boundaries, and even when the DMA operation starts at an offset within the buffer or doesn't extend to the end of the buffer, it's safe to flush the complete cachelines that were only partially involved in the DMA. This is because there's a very strict rule on these types of buffers that there will not be concurrent access by the CPU and one or more DMA transfers within the buffer.

Rewrite it to perform checks outside of the ancestor loop if they're based on information that's wholly contained within the original tag. Now the loop only checks exclusion zones in ancestor tags. Also, add a new function, might_bounce() which does a fast inline check of flags within the tag and map to quickly eliminate the need to call the more expensive must_bounce() for each page in the DMA operation. Within the mapping loops, use map->pagesneeded != 0 as a proxy for all the various checks on whether bouncing might be required. If no pages were reserved for bouncing during the checks before the mapping loop, then there's no need to re-check any of the conditions that can lead to bouncing -- all those checks already decided there would be no bouncing.

The current seekdir code with SINGLEUSE enabled breaks this case as each call to telldir() allocates a new cookie.

Information like rootpath or rootip aren't that useful for TFTP and the gateway IP is typically already printed by the firmware. 2. Only set boot.nfsroot.* environment variables for NFS. This makes it possible for the OS to work either way by checking for the presence or absence of environment variables. 3. Set boot.netif.server when using TFTP so that the OS can fetch files as well. A typical use case for this is network-based installations with the installation process implemented on top of FreeBSD. 4. The pxelinux loader has a set of alternative names it tries for configuration files. Make it easier to do something similar in Forth by providing the IP address as a 32-bit hex number in the pxeboot.ip variable and the MAC address with dashes in the pxeboot.hwaddr environment variable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | particular, allow loaders to define the name of the RC script the interpreter needs to use. Use this new-found control to have the PXE loader (when compiled with TFTP support and not NFS support) read from ${bootfile}.4th, where ${bootfile} is the name of the file fetched by the PXE firmware. The normal startup process involves reading the following files: 1. /boot/boot.4th 2. /boot/loader.rc or alternatively /boot/boot.conf When these come from a FreeBSD-defined file system, this is all good. But when we boot over the network, subdirectories and fixed file names are often painful to administrators and there's really no way for them to change the behaviour of the loader.
