[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

[netdevice] Allow network devices to disclaim IRQ support at runtime

2015-07-28T14:14:40+00:00

VLAN and 802.11 devices use a network device operations structure that wraps an underlying structure. For example, the vlan_operations structure wraps the network device operations structure of the underlying trunk device. This can cause false positives from the current implementation of netdev_irq_supported(), which will always report that VLAN devices support interrupts since it has no visibility into the support provided by the underlying trunk device. Fix by allowing network devices to explicitly flag that interrupts are not supported, despite the presence of an irq() method. Originally-fixed-by: Wissam Shoukair Signed-off-by: Michael Brown

[802.11] Use correct SHA1_DIGEST_SIZE constant name

The constant SHA1_SIZE is defined only as part of the imported AXTLS code. Signed-off-by: Michael Brown

[build] Fix the REQUIRE_SYMBOL mechanism

2015-03-05T00:59:38+00:00

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.

[settings] Explicitly separate the concept of a completed fetched setting

2013-12-05T00:37:02+00:00

The fetch_setting() family of functions may currently modify the definition of the specified setting (e.g. to add missing type information). Clean up this interface by requiring callers to provide an explicit buffer to contain the completed definition of the fetched setting, if required. Signed-off-by: Michael Brown
