[librm] Ensure that inline code symbols are unique

2018-03-21T15:00:53+00:00

Commit 6149e0a ("[librm] Provide symbols for inline code placed into other sections") may cause build failures due to duplicate label names if the compiler chooses to duplicate inline assembly code. Fix by using the "%=" special format string to include a guaranteed-unique number within the label name. The "%=" will be expanded only if constraints exist for the inline assembly. This fix therefore requires that all REAL_CODE() fragments use a (possibly empty) constraint list. Signed-off-by: Michael Brown

[cpuid] Allow input %ecx value to be specified

2017-06-16T00:17:48+00:00

For some CPUID leaves (e.g. %eax=0x00000004), the result depends on the input value of %ecx. Allow this subfunction number to be specified as a parameter to the cpuid() wrapper. The subfunction number is exposed via the ${cpuid/...} settings mechanism using the syntax ${cpuid/.0x40..} e.g. ${cpuid/0.0x40.0.0x0000000b} ${cpuid/1.0x40.0.0x0000000b} to retrieve the CPU topology information.

[time] Allow timer to be selected at runtime

2017-01-26T08:17:37+00:00

Allow the active timer (providing udelay() and currticks()) to be selected at runtime based on probing during the INIT_EARLY stage of initialisation. TICKS_PER_SEC is now a fixed compile-time constant for all builds, and is independent of the underlying clock tick rate. We choose the value 1024 to allow multiplications and divisions on seconds to be converted to bit shifts. TICKS_PER_MS is defined as 1, allowing multiplications and divisions on milliseconds to be omitted entirely. The 2% inaccuracy in this definition is negligible when using the standard BIOS timer (running at around 18.2Hz). TIMER_RDTSC now checks for a constant TSC before claiming to be a usable timer. (This timer can be tested in KVM via the command-line option "-cpu host,+invtsc".) Signed-off-by: Michael Brown

[af_packet] Add new AF_PACKET driver for Linux

2017-01-22T14:02:54+00:00

This code largely inspired by tap.c. Allows for testing iPXE on real NICs from within Linux. For example: make bin-x86_64-linux/af_packet.linux valgrind ./bin-x86_64-linux/af_packet.linux --net af_packet,if=eth3 Tested as x86_64 and i386 binary. Signed-off-by: Michael Brown

[pci] Support systems with multiple PCI root bridges

2016-06-09T08:36:28+00:00

Extend the 16-bit PCI bus:dev.fn address to a 32-bit seg:bus:dev.fn address, assuming a segment value of zero in contexts where multiple segments are unsupported by the underlying data structures (e.g. in the iBFT or BOFM tables). Signed-off-by: Michael Brown

[tcpip] Do not fall back to using unoptimised TCP/IP checksumming

2016-05-04T12:38:25+00:00

Require architecture-specific code to make a deliberate choice to use the unoptimised generic_tcpip_continue_chksum() function, if there is no optimised version available. Signed-off-by: Michael Brown
