* [vram] Add "vram" built-in setting to dump video RAMMichael Brown2015-04-242-0/+4
| | | | | | | | | | | | | | | | | | | | The "vram" setting returns the (Base64-encoded) contents of video RAM, and can be used to capture a screenshot. For example: after running memtest.0 and encountering an error, the output can be captured and sent to a remote server for later diagnosis: #!ipxe chain -a http://server/memtest.0 && goto ok || goto bad :bad params param errno ${errno} param vram ${vram} chain -a http://server/report.php##params :ok Inspired-by: Christian Nilsson <nikize@gmail.com> Originally-implemented-by: Christian Nilsson <nikize@gmail.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [romprefix] Allow autoboot device filter to be disabledMichael Brown2015-04-131-0/+1
| | | | | | | | | | | | | | | | | Our current behaviour when booting as a ROM is to autoboot only from devices which are attached via the PCI bus:dev.fn address passed to the ROM's initialisation vector. Add a build configuration option AUTOBOOT_ROM_FILTER (enabled by default) to control this behaviour. This allows for ROMs to be built which will attempt to boot from any detected device, even if not attached via the original PCI bus:dev.fn address. (This is particularly useful when building combined EHCI/xHCI ROMs for USB network boot, since the BIOS may request a boot via the EHCI controller but the xHCI driver will reroute the root hub ports to the xHCI controller.)

* [build] Fix the REQUIRE_SYMBOL mechanismMichael Brown2015-03-058-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | At some point in the past few years, binutils became more aggressive at removing unused symbols. To function as a symbol requirement, a relocation record must now be in a section marked with @progbits and must not be in a section which gets discarded during the link (either via --gc-sections or via /DISCARD/). Update REQUIRE_SYMBOL() to generate relocation records meeting these criteria. To minimise the impact upon the final binary size, we use existing symbols (specified via the REQUIRING_SYMBOL() macro) as the relocation targets where possible. We use R_386_NONE or R_X86_64_NONE relocation types to prevent any actual unwanted relocation taking place. Where no suitable symbol exists for REQUIRING_SYMBOL() (such as in config.c), the macro PROVIDE_REQUIRING_SYMBOL() can be used to generate a one-byte-long symbol to act as the relocation target. If there are versions of binutils for which this approach fails, then the fallback will probably involve killing off REQUEST_SYMBOL(), redefining REQUIRE_SYMBOL() to use the current definition of REQUEST_SYMBOL(), and postprocessing the linked ELF file with something along the lines of "nm -u | wc -l" to check that there are no undefined symbols remaining.

* [dhcp] Extract timing parameters out to config/dhcp.hAlex Williamson2015-02-251-0/+87
| | | | | | | | | | | | | | iPXE uses DHCP timeouts loosely based on values recommended by the specification, but often abbreviated to reduce timeouts for reliable and/or simple network topologies. Extract the DHCP timing parameters to config/dhcp.h and document them. The resulting default iPXE behavior is exactly the same, but downstreams are now afforded the opportunity to implement spec-compliant behavior via config file overrides.

* [build] Allow for named configurations at build timeMichael Brown2014-08-208-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [romprefix] Allow ROM banner timeout to be configured independentlyAlex Williamson2014-03-031-4/+15
| | | | | | | | | | | | | | | | | iPXE currently prints a "Press Ctrl-B" banner twice: once when the ROM is first called for initialisation and again if we attempt to boot from the ROM. This slows boot, especially when the NIC is not the primary boot device. Tools such as libguestfs make use of QEMU VMs for performing maintenance on disk images and may make use of NICs in the VM for network support. If iPXE introduces a static init-time delay, that directly translates to increased runtime for the tools. Fix by allowing the ROM banner timeout to be configured independently of the main banner timeout.

* [ipv6] Replace IPv6 stackMichael Brown2013-09-033-0/+7
| | | | | | | | | | | | | | | | Replace the existing partially-implemented IPv6 stack with a fresh implementation. This implementation is not yet complete. The IPv6 transmit and receive datapaths are functional (including fragment reassembly and parsing of arbitrary extension headers). NDP neighbour solicitations and advertisements are supported. ICMPv6 echo is supported. At present, only link-local addresses may be used, and there is no way to specify an IPv6 address as part of a URI (either directly or via a DNS lookup).

* [settings] Expose memory map via settings mechanismMichael Brown2013-08-122-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow memory map entries to be read using the syntax ${memmap/<region>.<properties>.<scale>} where <region> is the index of the memory region, <properties> is a bitmask where bit 0 represents the start address and bit 1 represents the length (allowing the end address to be encoded by having both bits 0 and 1 set), and <scale> is the number of bits by which to shift the result. This allows for several values of interest to be encoded. For example: ${memmap/<region>.1.0:hexraw} # 64-bit start address of <region> ${memmap/<region>.2.0:hexraw} # 64-bit length of <region>, in bytes ${memmap/<region>.3.0:hexraw} # 64-bit end address of <region> ${memmap/<region>.2.10:int32} # Length of <region>, in kB ${memmap/<region>.2.20:int32} # Length of <region>, in MB The numeric encoding is slightly more sophisticated than described here, allowing a single encoding to cover multiple regions. (See the source code for details.) The primary use case for this feature is to provide the total system memory size (in MB) via the "memsize" predefined setting.

* [settings] Expose CPUID instruction via settings mechanismMichael Brown2013-08-072-0/+4
| | | | | | | | | | | | | | | | | | | | | | | Allow CPUID values to be read using the syntax ${cpuid/<register>.<function>} For example, ${cpuid/2.0x80000001} will give the value of %ecx after calling CPUID with %eax=0x80000001. Values for <register> are encoded as %eax=0, %ebx=1, %ecx=2, %edx=3. The numeric encoding is more sophisticated than described above, allowing for settings such as the CPU model (obtained by calling CPUID with %eax=0x80000002-0x80000004 inclusive and concatenating the values returned in %eax:%ebx:%ecx:%edx). See the source code for details. The "cpuvendor" and "cpumodel" settings provide easy access to these more complex CPUID settings. This functionality is intended to complement the "cpuid" command, which allows for testing individual CPUID feature bits. Signed-off-by: Michael Brown <mcb30@ipxe.org>
