* core: get rid of unmangle_name completelysyslinux-4.00-pre31H. Peter Anvin2010-02-281-3/+2
| | | | | | | | | | | | The notion of "mangle name" is now restricted to producing a canonical representation, e.g. changing \ -> / for FAT filesystems. However, the resulting mangled name is now always human-readable, so there never is any reason to unmangle a name. Get rid of not just the mangling, but of the resulting unmangled-name buffers and so on. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* config: allow a chdir at the time a new configuration file is loadedH. Peter Anvin2010-02-141-6/+6
| | | | | | | | If a directory name/path prefix is appended to a loaded configuration file, do a chdir at that point. We finally have all the mechanism to do this right. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* fs: move to a chdir()-based mechanism for managing cwdsyslinux-4.00-pre19H. Peter Anvin2010-02-131-1/+1
| | | | | | | | | | | | Introduce a chdir() system and a way to obtain absolute pathnames. This should allow us to set the current base directory (filename prefix for PXE) without breaking access to the configuration file. As a side benefit, for the "normal" filesystems we no longer need magic hacks to figure out where we should set our current working directory. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* Core: Convert the searchdir function to CLiu Aleaxander2009-06-051-1/+1
| | | | | | | | | for now, almost all the stuff related to EXT have been converted to C, and fow my (limit) test, it works well. The getfssec function haven't converted to C, because it also be called from asm file, and I find it's a bit hard to convert it to C. But however, it's my next plan.
* Convert the config load part to CLiu Aleaxander2009-06-031-1/+1
| | | | | | | | | For now, I added a temporary file load_config.c that would be merged into extlinux.c file later, which would make my later work be much easier. And in order to get rid of the conflict noisy message from the open function in ui.inc and the open function defined in the unistd.h, I changed the open in core to core_open. It may be ugly, but it works :)

| * core: don't flush the serial port queue for a serial commandH. Peter Anvin2009-05-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Don't flush the serial port queue when encountering a "serial" command. We don't actually want to lose data due to a repeated "serial", since it's quite likely it's exactly the same as before. Do flush the queue on hardware cleanup, however. Also fix some minor bugs, including a bunch of code in the .data segment. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
| * core: add a proper interrupt handler for the serial consoleH. Peter Anvin2009-05-231-19/+20
| | | | | | | | | | | | | | | | | | If we enable interrupts for the serial console, add a proper interrupt handler. Since we don't know what vector we'll end up using, or if we are shared with other devices, simply hook *all* the interrupts and poll the serial port then. Signed-off-by: H.

| | | | | | | | | | | | | | | | | | | | | | Try to HLT the processor during idle. All the events we care about should have interrupts associated with them, except possibly the serial console. Try to deal with the serial console by waiting some time before going into HLT, and giving the user the option of enabling the serial console interrupt, on the assumption that the BIOS will simply IRET.

* | core: add pm_call convenience macroH. Peter Anvin2009-05-151-3/+1
| | | | | | | | | | | | | | | | | | Add a pm_call convenience macro, instead of using stub routines everywhere. Stubs would still make sense if we have a routine which gets invoked from a lot of places, though, since the pm_call expands to 9 bytes as opposed to 3 bytes per call site plus a 10-byte stub.

|/ | | | | | | | Rename the .text, .data and .bss sections to .text16, .data16 and .bss16, in anticipation of being linked with compiler-generated 32-bit code, which presumably would like to use the standard section names. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* core: make vk_rname default to mangled vk_vnameSebastian Herbszt2009-05-021-7/+6
| | | | | | | Change pc_label in parseconfig.inc to default vk_rname to mangled vk_vname. Also change spaces to tabs. This gives a usable error message in the case where the user selects a label without any kernel information.
* core: make localboot another vkernel typesyslinux-3.80-pre4H. Peter Anvin2009-04-291-12/+3
| | | | | | | | | Change "localboot" to be another vkernel type. It still needs some special treatment (because it doesn't take a filename), but overall this makes it a lot cleaner than what it was before. It should also avoid the problem of empty labels (e.g. menu quit) doing weird things. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* Refactor command line parsing; support "quiet" optionsyslinux-3.74-pre7H. Peter Anvin2009-03-181-2/+2
| | | | | | | | Refactor the command line parser to be more of a general parser instead of treating each option as an ad hoc feature. Suppress the Loading... prompt if "quiet" is specified on the command line. Some messed-up people want it this way.
* parseconfig.inc: use "skipline" where appropriateH. Peter Anvin2009-01-311-2/+2
| | | | Use "skipline" where appropriate instead of reading into the trackbuf.
* Make sure we eat the input when ignoring a DEFAULT commandH. Peter Anvin2009-01-311-3/+3
| | | | | | | | | Make sure we eat the rest of the input line when we encounter a DEFAULT command that is to be ignored because we have a UI command already. Do this by making skipline a subroutine. Based on a patch by Sebastian Hebszt <herbszt@gmx.de>, although substantially modified.
* Fix the new "UI" directiveSebastian Herbszt2008-12-141-0/+1
| | | | | | | | | The new directive doesn't seem to work here. Looks like DefaultLevel is never changed: core/parseconfig.inc:pc_default: cmp ax,[DefaultLevel] core/parseconfig.inc:DefaultLevel dw 0 ; The current level of default core/ui.inc: cmp word [DefaultLevel],1 ; Active UI statement?
* Add new "UI" directive instead of abusing the DEFAULT directiveH. Peter Anvin2008-12-141-3/+6
| | | | | | | | | Add a new "UI" directive to specify a user interface module, instead of abusing the DEFAULT directive. This allows the DEFAULT directive to be used for setting the default, even when the menu system is enabled. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Add Tab display of labelssyslinux-3.72-pre6H. Peter Anvin2008-09-091-0/+1

* Correctly parse "serial" statements with no baud rateH. Peter Anvin2008-07-171-7/+6

* parseconfig: fix invalid mangle_name assumptionH. Peter Anvin2008-07-161-1/+1
| | | | | | | | Remove assumption that mangle_name leaves DI beyond the end of the buffer. This was true back when the mangled filename buffer was an 11-byte DOS filename, but it is definitely not true anymore. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Allow the initrd to be specified on a separate linesyslinux-3.71-pre4H. Peter Anvin2008-07-031-5/+27
| | | | | Allow the initrd to be specified on a separate line from command-line options (append). This apparently can help certain tools.

* Mechanically rename the writestr functionsH. Peter Anvin2008-06-151-2/+2
| | | | | | | | | | Mechanically rename the writestr functions: writestr -> writestr_early cwritestr -> writestr ... to reflect which function is more appropriate to call in normal circumstances.
* Move files out of root into core, dos, and utilsH. Peter Anvin2008-05-291-0/+454
Move source files out of the root directory; the root is a mess and has become virtually unmaintainable. The Syslinux core now lives in core/; the Linux and generic utilities has moved into utils/, and copybs.com has moved into dos/; it had to go somewhere, and it seemed as good a place as any.
