* [int13con] Add basic ability to log to a local disk via INT 13Michael Brown2015-05-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Several popular public cloud providers do not provide any sensible mechanism for obtaining debug output from an OS which is failing to boot. For example, Amazon EC2 provides the "Get System Log" facility, which occasionally deigns to report a random subset of the characters emitted via the VM's serial port, but usually returns only a blank screen. (Amazingly, this is still superior to the debugging facilities provided by Azure.) Work around these shortcomings by adding a console type which sends output to a magically detected raw disk partition, and including such a partition within any iPXE .usb-format image. To use this facility: - build an iPXE .usb image with CONSOLE_INT13 enabled - boot the cloud VM from this image - after the boot fails, attach the VM's boot disk to a second VM - from this second VM, use "less -f -R /dev/sdb3" (or similar) to view the iPXE output.

* [build] Allow for named configurations at build timeMichael Brown2014-08-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow named configurations to be specified via the CONFIG=... build parameter. For headers in config/*.h which support named configurations, the following files will be included when building with CONFIG=<name>: - config/defaults/<platform>.h (e.g. config/defaults/pcbios.h) - config/<header>.h - config/<name>/<header>.h (only if the directory config/<name> exists) - config/local/<header>.h (autocreated if necessary) - config/local/<name>/<header>.h (autocreated if necessary) This mechanism allows for predefined named configurations to be checked in to the source tree, as a directory config/<name> containing all of the required header files. The mechanism also allows for users to define multiple local configurations, by creating header files in the directory config/local/<name>. Note that the config/*.h files which are used only to configure internal iPXE APIs (e.g. config/ioapi.h) cannot be modified via a named configuration. This avoids rebuilding the entire iPXE codebase whenever switching to a different named configuration.

* [vesafb] Add VESA frame buffer consoleMichael Brown2013-11-281-0/+1
| | | | | | | | | | | The VESA frame buffer console uses the VESA BIOS extensions (VBE) to enumerate video modes, selects an appropriate mode, and then hands off to the generic frame buffer code. The font is extracted from the VGA BIOS, avoiding the need to provide an external font file. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [syslog] Add basic support for encrypted syslog via TLSMichael Brown2012-04-101-0/+1
| | | | | | | Encrypted syslog seems not yet to be standardised, but is supported by some existing syslog servers. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [console] Add "log message" console usage and an internal syslog() callMichael Brown2012-03-261-0/+2
| | | | | | | | | | | | | | | Provide an internal syslog() function (unrelated to the syslog console) which can be used to create log messages with specified priorities. The build-time constant LOG_LEVEL can be used to select the minimum required priority for log messages. Any messages that do not have a sufficient priority will be ignored (and will be optimised away at compile-time). The default LOG_LEVEL is LOG_NONE. Signed-off-by: Michael Brown <mcb30@ipxe.org>
