2017-09-28util/cbmem: be explicit about memory map sizesAaron Durbin
The cbmem utility has inherited some workarounds that originated from the default 1 MiB mapping always working. This 1 MiB mmap won't necessarily succeed if the 1 MiB encroaches on a subsequent memory range that has different cacheability. To fix this, map in only 4 KiB when the table size is not known which is the case for any forwarding entry or any low table entries on x86. That smaller mapping is then searched for a valid header. Once a valid header is found the full table is mapped and parsed allowing a forwarding entry to take precedence. Lastly, the lbtable is kept mapped in such that other operations can just operate on mapping that was previously parsed. In order to allow multiple in-flight mappings a struct mapping was added which caused the ripple within the code. However, there shouldn't be any more reasons for putting weird heuristics for when to fail. If the tables are bad then it's very much possible that mappings will fail. Retrying when the exact sizes are already known won't fix those issues.

2017-05-18cbmem_console: Improve 'cbmem -1' behavior for truncated pre-CBMEM logsJulius Werner
The 'cbmem -1' flag that cuts off console output before the last boot will ignore content from earlier stages if it was truncated due to lack of pre-CBMEM console space. This patch makes the "log truncated" message more specific and adds it as an additional cut-off marker to 'cbmem -1' to counteract that problem. Also raise the log level of the coreboot banner one step to BIOS_NOTICE to make it more likely to be included in the output for 'cbmem -1' to find. (I believe NOTICE is reasonable but I wouldn't want to go as far as WARN which should be reserved for actual problems. Of course this is not ideal, but then again, our whole log-level system really isn't... it would be better if we could make it always print a banner to the CBMEM console without affecting the UART at the same time, but that would require a larger amount of work.)

2017-05-15util/cbmem: mmap underflow on low addressesAaron Durbin
There is code to adjust the mapping down if a mmap fails at a physical address. However, if the address is less than the page size of the system then the physical offset will underflow. This can actually cause a kernel panic on when operating on /dev/mem. The failing condition happens when the requested mapping at 0 fails in the kernel. The fallback path is taken and page size is subtracted from 0 making a very large offset. The PAT code in the kernel fails with a BUG_ON in reserve_memtype() checking start >= end. The kernel needs to be fixed as well, but this fallback path is wrong as well.

Even though the persistent CBMEM console is obviously awesome, there may be cases where we only want to look at console output from the last boot. It's easy to tell where one boot ends and another begins from the banner message that coreboot prints at the start of every stage, but in order to make it easier to find that point (especially for external tools), let's put that functionality straight into the cbmem utility with a new command line flag. Use the POSIX/libc regular expression API to find the banner string for maximum compatilibity, even though it's kinda icky.

2017-04-20Turn CBMEM console into a ring buffer that can persist across rebootsJulius Werner
This patch allows the CBMEM console to persist across reboots, which should greatly help post factum debugging of issues involving multiple reboots. In order to prevent the console from filling up, it will instead operate as a ring buffer that continues to evict the oldest lines once full. (This means that if even a single boot doesn't fit into the buffer, we will now drop the oldest lines whereas previous code would've dropped the newest lines instead.) The console control structure is modified in a sorta backwards-compatible way, so that new readers can continue to work with old console buffers and vice versa. When an old reader reads a new buffer that has already once overflowed (i.e. is operating in true ring buffer mode) it will print lines out of order, but it will at least still print out the whole console content and not do any illegal memory accesses (assuming it correctly implemented cursor overflow as it was already possible before this patch). BUG=chromium:651966 TEST=Rebooted and confirmed output repeatedly on a Kevin and a Falco. Also confirmed correct behavior across suspend/resume for the latter.

2017-04-14cbmem: Add custom aligned memcpy() implementationJulius Werner
On some architectures (like AArch64), /dev/mem mappings outside of the area marked as normal RAM use a memory type that does not support unaligned accesses. The libc memcpy() implementation on these architectures may not know or expect that and make an unaligned access for certain source/dest/length alignments. Add a custom memcpy() implementation that takes these restrictions into account and use it anywhere we copy straight out of /dev/mem memory.

2016-02-22cbfs: Add LZ4 in-place decompression support for pre-RAM stagesJulius Werner
This patch ports the LZ4 decompression code that debuted in libpayload last year to coreboot for use in CBFS stages (upgrading the base algorithm to LZ4's dev branch to access the new in-place decompression checks). This is especially useful for pre-RAM stages in constrained SRAM-based systems, which previously could not be compressed due to the size requirements of the LZMA scratchpad and bounce buffer. The LZ4 algorithm offers a very lean decompressor function and in-place decompression support to achieve roughly the same boot speed gains (trading compression ratio for decompression time) with nearly no memory overhead. For now we only activate it for the stages that had previously not been compressed at all on non-XIP (read: non-x86) boards. In the future we may also consider replacing LZMA completely for certain boards, since which algorithm wins out on boot speed depends on board-specific parameters (architecture, processor speed, SPI transfer rate, etc.). BRANCH=None BUG=None TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on Oak to be about ~20ms faster (cutting load times for affected stages almost in half).

Add the timestamp tick frequency within the timestamp table so the cbmem utility doesn't try to figure it out on its own. Those paths still exist for x86 systems which don't provide tsc_freq_mhz(). All other non-x86 systems use the monotonic timer which has a 1us granularity or 1MHz. One of the main reasons is that Linux is reporting /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq as the true turbo frequency on turbo enables machines. This change also fixes the p-state values honored in cpufreq for turbo machines in that turbo p-pstates were reported as 100MHz greater than nominal.

2015-04-14timestamps: You can never have enough of them!Julius Werner
Now that we have timestamps in pre-RAM stages, let's actually make use of them. This patch adds several timestamps to both the bootblock and especially the verstage to allow more fine-grained boot time tracking. Some of the introduced timestamps can appear more than once per boot. This doesn't seem to be a problem for both coreboot and the cbmem utility, and the context makes it clear which operation was timestamped at what point. Also simplifies cbmem's timestamp printing routine a bit, fixing a display bug when a timestamp had a section of exactly ",000," in it (e.g. 1,000,185). BRANCH=None BUG=None TEST=Booted Pinky, Blaze and Falco, confirmed that all timestamps show up and contained sane values.
