* In the current Lua.c32 DMI implementation, it is a flat table with dotted ↵Hung-chi Lihn2012-09-222-208/+420
| | | | | | | | | names in table entries. It also misses a number DMI sub-tables. This patch, cleans up the DMI table structure using Lua's nested table structure and adds all missing DMI sub-tables. If a DMI sub-table is not supported by the hardware (not filled), then the corresponding sub-table will not be generated. This helps to make the table structure cleaner and reflects the actual DMI information. Signed-off-by: Hung-chi Lihn <hlihn@google.com> Signed-off-by: Erwan Velu <erwanaliasr1@gmail.com>
* Added the native syslinux functions config_file(), ipappend_strs(), and ↵Hung-chi Lihn2012-09-221-0/+33
| | | | | | | | | | | | reboot() to Lua.c32. This allows the Lua script to query the config file name and the ipappend strings (pxelinux only), as well as to perform reboot (warm and cold) to the system. In Lua.c32, the extension will be used as the following: 1. syslinux.config_file() will return the config file string. 2. syslinux.ipappend_strs() will return a table of IPAPPEND strings with numerical indices. 3. syslinux.reboot() will perform cold reboot, while syslinux.reboot(1) will perform warm reboot.

* The current Lua.c32 does not enable io.read() due to some missing library ↵Hung-chi Lihn2012-09-221-11/+29
| | | | | | | | | | | | functions. However, this strongly limits the Lua script from getting user inputs and reading files (even in pxelinux via TFTP). This patch enables io.read() in Lua.c32 with some restrictions: 1. the io.read("*line") is fully supported. 2. the io.read("*number") is not supported due to the missing buffering in underlying file I/Os. However, the user can read a line using io.read() and convert the string to numbers using the built in pattern matching and number conversion features. 3. io.read(bytes) is supported. However, io.read(0) will not be a valid test for EOF due to the missing I/O buffering. io.read() will return nil if EOF is encountered. This offers an alternative way to handle EOF.

Many of the options are reurned formatted in as strings in a standard, recognizable format, such as IP addresses. 1, 2, and 4 byte numerical options are returned as integers. Other Options with non-standard formats are returned as strings of the raw binary number that was returned by the DHCP server and must be decoded in a Lua script The Options table returns the Option code as the key except where there are multiple values returned. In those cases, an extra key increment number is added to allow individual access to each Option value. lua key value value Name ----------------------------------------------------------------------- 1 Subnet Mask 6.1 DNS Server [element 1] 6.2 DNS Server [element 2] 6.3 DNS Server [element 3] 209 PXE Configuration File 21.1 Policy Filter [element 1] 21.2 Policy Filter [element 2] Options that can have a list of values, but contain only one (like Option 6) will not return with .sub key values.

* lua: Delete superfluous $(LIBS) prerequisiteMatt Fleming2011-04-161-2/+1
| | | | | | | com32.mk already includes the necessary library in $(C_LIBS), we don't need to list them again in $(LIBS). Signed-off-by: Matt Fleming <matt.fleming@linux.intel.com>
* Makefile: Move Makefile fragments into mk/Matt Fleming2011-04-071-1/+2
| | | | | | | | | | | | | | | | | | Move the MCONFIG files into a mk/ directory and give them more descriptive names. This is purely a cosmetic change to make the 'include' directives a bit more coherent by making it obvious exactly which MCONFIG file we're including. For example, in com32/lua/src/Makefile we exchange the line, include ../../MCONFIG for the much more comprehensible, include $(MAKEDIR)/com32.mk Signed-off-by: Matt Fleming <matt.fleming@linux.intel.com>

(s. com32/lua/test/dmi.lua) - syslinux: - loading files, kernel, initrd - start kernel, initrd, local boot ... just working on this, so no example lua file right now Most of the actual merging work was done by Gert Hulselmans <gerth@zytor.com>.
