* Mega i386 loader commit.John Baldwin2000-03-2818-271/+1610
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Don't hard code 0x10000 as the entry point for the loader. Instead add src/sys/boot/i386/Makefile.inc which defines a make variable with the entry point for the loader. Move the loader's entry point up to 0x20000, which makes PXE happy. - Don't try to use cpp to parse btxldr for the optional BTXLDR_VERBOSE, instead use m4 to achieve this. Also, add a BTXLDR_VERBOSE knob in the btxldr Makefile to turn this option on. - Redo parts of cdldr's Makefile so that it now builds and installs cdboot instead of having i386/loader/Makefile do that. Also, add in some more variables to make the pxeldr Makefile almost identical and thus to ease maintainability. - Teach cdldr about the a.out format. Cdldr now parsers the a.out header of the loader binary and relocates it based on that. The entry point of the loader no longer has to be hardcoded into cdldr. Also, the boot info table from mkisofs is no longer required to get a useful cdboot. - Update the lsdev function for BIOS disks to parse other file systems (such as DOS FAT) that we currently support. This is still buggy as it assumes that a floppy with a DOS boot sector actually has a MBR and parses it as such. I'll be fixing this in the future. - The biggie: Add in support for booting off of PXE-enabled network adapters. Currently, we use the TFTP API provided by the PXE BIOS. Eventually we will switch to using the low-level NIC driver thus allowing both TFTP and NFS to be used, but for now it's just TFTP.

* This patch to BTX fixes several small things:John Baldwin2000-02-162-12/+58
| | | | | | | | | | | | | | | | | | | | | | | | 1) Fix a bug in the int15 function 87 emulation where we only copied half of what the BIOS asked for. This caused the Mylex RAID adapter to go haywire and start trashing memory when you tried to boot from it. 2) Don't use interrupt 19 to reboot. Instead, set the reboot flag to a warm boot and jump to the BIOS's reboot handler. int 19 doesn't clear memory or restore the interrupt vector table, and thus really isn't safe. For example, when booting off of PXE, the PXE BIOS eats up a chunk of memory for its internal data and structures. Since we rebooted via int 19, using the 'reboot' command in the loader resulted in that memory not being reclaimed by the BIOS. Thus, after a few PXE boots, the system was out of lower memory. 3) Catch any int 19 calls made by a BTX client or a user pressing Ctrl-Alt-Delete and shutdown BTX and reboot the machine cleanly. This fixes Ctrl-Alt-Delete in the loader and in boot2 instead of presenting the user with a BTX fault. Approved by: jkh Found by: 1) by msmith Notes: svn path=/head/; revision=57254

* Add the new cdldr CD bootstrap loader. This patch includes the following:John Baldwin2000-01-279-8/+589
| | | | | | | | | | | | | | | | | | | - Fix btxldr to preserve a NULL bootinfo pointer when it copies the kernel arguments. - Add the cdldr bootstrap program. This program is tacked onto the beginning of the standard 3rd stage boot loader (/boot/loader) to form the CD boot loader (/boot/cdboot). When a CD is booted, the cdboot file is copied into memory instead and executed. The cdldr stub emulates the environment normally provided by boot2 and then starts the loader. This booting method does not emulate a floppy drive, but boots directly off of the CD. This should fix the problems some BIOS's have with emulating a 2.88 MB floppy image. - Add support to the loader to recognize that it has been booted by cdldr instead of boot2 and use a simpler method of extracting the BIOS boot device.

| | | | | | | | | | | | of %cr0 wasn't reloaded into %eax before being modified to turn protected mode off if PAGING was not defined. The result was that the processor did not exit protected mode, so when it tried to jump to segment 0x0 in the next instruction to clear the prefetch cache like one should when leaving protected mode, it actually tried to jump to a null selector, causing a GPF.

PCCARD, ISA and PCI attachments are all provided. Also provided an ancontrol(8) utility for configuring the NIC, man pages, and updated pccard.conf.sample. ISA cards are supported in both ISA PnP and hard-wired mode, although you must configure the kernel explicitly to support the hardwired mode since you have to know the I/O address and port ahead of time. Special thanks to Doug Ambrisko for doing the initial newbus hackery and getting it to work in infrastructure mode. Notes: svn path=/head/; revision=55992
* Add device driver support for USB ethernet adapters based on the CATCBill Paul2000-01-141-0/+1
| | | | | | | | | | | | | | | | | | | USB-EL1202A chipset. Between this and the other two drivers, we should have support for pretty much every USB ethernet adapter on the market. The only other USB chip that I know of is the SMC USB97C196, and right now I don't know of any adapters that use it (including the ones made by SMC :/ ). Note that the CATC chip supports a nifty feature: read and write combining. This allows multiple ethernet packets to be transfered in a single USB bulk in/out transaction. However I'm again having trouble with large bulk in transfers like I did with the ADMtek chip, which leads me to believe that our USB stack needs some work before we can really make use of this feature. When/if things improve, I intend to revisit the aue and cue drivers. For now, I've lost enough sanity points. Notes: svn path=/head/; revision=55944

Allow the loader to use all of the detected physical memory (this will greatly help people trying to load enormous memory disk images).

* This commit adds device driver support for the ADMtek AN986 PegasusBill Paul1999-12-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory Notes: svn path=/head/; revision=55162
