Added IOCache, a simple write-through cache implementation that can be used as a drop-in replacement for IOScheduler, processing IORequests synchronously in FIFO order. It stores cache lines of user-defined size. Currently for each cache line an area of contiguous memory is used, which is not optimal. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36436 a95241bf-73f2-0310-859d-f6bbb57e9c96

* VFS: - Fixed vfs_get_vnode_from_fd() return type. - Added vfs_open_vnode(). - Added a "bool traverseLeafLink" parameter to vfs_get_fs_node_from_path(). It was always resolving symlinks. * device manager/devfs: - devfs: get_node_for_path() no longer resolves leaf symlinks. That still doesn't help with file disk devices, as creating partition wouldn't work anyway. - Pulled the module-related implementation part of BaseDevice into new class AbstractModuleDevice and made all methods of BaseDevice virtual. Small adjustments to devfs to be happy with the new BaseDevice interface. - Added BaseDevice subclass FileDevice, which maps the interface to a file's file descriptor. Still got a few TODOs, but should basically work. - Use FileDevice for publishing file disk devices in devfs. Now those do actually work, though there's some BFS trouble with one of the images I tested. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33385 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added option for enabling serial debug output. * Moved device_manager/settings.cpp to debug/safemode_settings.cpp. * Removed the somewhat hacky concatenation of kernel settings and safemode settings in the boot loader. Instead, get_safemode_option() will now fall back to the kernel settings, if it couldn't spot a setting in the safemode settings. This allows for more control, and also makes enabling serial debug output actually work (ie. overriding the kernel settings via safemode options). * Adjusted debug_init_post_vm(), and smp_init_other_cpus() to use get_safemode_boolean(). * Therefore, I added safemode_settings.cpp to the boot loader as well. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32685 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Removed -Wno-unused from all KernelMergeObjects in kernel Jamfiles. * Fixed most of the warnings resulting from that by removing actually not used variables or moving declaration into the #IF. Left unused functions there though, as I wouldn't know if they are supposed to be used again. * Fixed two statements with no effect (clamping to MAX_ANCILLARY_DATA_LEN in socket.cpp and unsetting fCounterSem in MessagingService.cpp). * Some style cleanups. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26253 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Integration of the new driver architecture. * Moved devfs from fs/ to device_manager/, and separated the legacy driver support from it. * Removed fast_log module. * There are a couple of (temporary) regressions, though: - legacy SATA and ISA IDE support is disabled, the drivers haven't been ported yet. - The not yet used ATA bus manager hasn't been ported yet, either. - AHCI changes have not been tested. - the listdev command has been removed from the build (as it currently doesn't work anymore). - device manager generated IDs currently are not freed anymore when a device node is removed. - generic drivers can't yet use the new driver architecture. - simple busses that do not support device types won't work yet. - legacy driver publishing/unpublishing (ie. what USB needs) has not been tested, and may be broken. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25662 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Started implementing node monitoring in the devfs and device manager. * Right now, only already known loaded drivers will be monitored for changes; their devices aren't republished, though, since that would cause a deadlock in the node notification mechanism (listeners are called synchronously); need to offload that the event handling to another thread. * On changes of (known) driver directories, the device manager will now print some info to the syslog. * Fixed republish_driver() I broke recently (would skip every other node), and moved it to the driver functions section of the devfs.cpp. * Implemented currently unused unpublish_driver() function that would have to be called before reloading a driver. * If a driver is in use when it's updated, we mark it, but we don't do anything with that info when we could. * Minor cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24036 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Introduced new build system variables {HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the compiler/linker flags specifying the kind of position independence the kernel shall have. For x86 we had and still have -fno-pic, but the PPC kernel has -fPIE (position independent executable) now, as we need to relocate it. * The boot loader relocates the kernel now. Mostly copied the relocation code from the kernel ELF loader. Almost completely rewrote the PPC specific relocation code, though. It's more correct and more complete now (some things are still missing though). * Added boot platform awareness to the kernel. Moved the generic Open Firmware code (openfirmware.c/h) from the boot loader to the kernel. * The kernel PPC serial debug output is sent to the console for the time being. * The PPC boot loader counts the CPUs now and allocates the kernel stacks (made OF device iteration a bit more flexible on the way -- the search can be restricted to subtree). Furthermore we really enter the kernel... (Yay! :-) ... and crash in the first dprintf() (in the atomic_set() called by acquire_spinlock()). kprintf() works, though. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15756 a95241bf-73f2-0310-859d-f6bbb57e9c96
