This coincides with 2^56 cycles at a +timer frequency of 24 MHz, implying that the time went slightly backward +(and this was interpreted by the kernel as it jumping forward and +wrapping around past the epoch). + +Investigation revealed instability in the low bits of CNTVCT at the +point a high bit rolls over. This leads to power-of-two cycle forward +and backward jumps. (Testing shows that forward jumps are about twice as +likely as backward jumps.) Since the counter value returns to normal +after an indeterminate read, each "jump" really consists of both a +forward and backward jump from the software perspective. + +Unless the kernel is trapping CNTVCT reads, a userspace program is able +to read the register in a loop faster than it changes. A test program +running on all 4 CPU cores that reported jumps larger than 100 ms was +run for 13.6 hours and reported the following: + + Count | Event +-------+--------------------------- + 9940 | jumped backward 699ms + 268 | jumped backward 1398ms + 1 | jumped backward 2097ms + 16020 | jumped forward 175ms + 6443 | jumped forward 699ms + 2976 | jumped forward 1398ms + 9 | jumped forward 356516ms + 9 | jumped forward 357215ms + 4 | jumped forward 714430ms + 1 | jumped forward 3578440ms + +This works out to a jump larger than 100 ms about every 5.5 seconds on +each CPU core. + +The largest jump (almost an hour!) was the following sequence of reads: + 0x0000007fffffffff → 0x00000093feffffff → 0x0000008000000000 + +Note that the middle bits don't necessarily all read as all zeroes or +all ones during the anomalous behavior; however the low 10 bits checked +by the function in this patch have never been observed with any other +value. + +Also note that smaller jumps are much more common, with backward jumps +of 2048 (2^11) cycles observed over 400 times per second on each core. +(Of course, this is partially explained by lower bits rolling over more +frequently.) Any one of these could have caused the 95 year time skip. + +Similar anomalies were observed while reading CNTPCT (after patching the +kernel to allow reads from userspace). However, the CNTPCT jumps are +much less frequent, and only small jumps were observed. The same program +as before (except now reading CNTPCT) observed after 72 hours: + + Count | Event +-------+--------------------------- + 17 | jumped backward 699ms + 52 | jumped forward 175ms + 2831 | jumped forward 699ms + 5 | jumped forward 1398ms + +Further investigation showed that the instability in CNTPCT/CNTVCT also +affected the respective timer's TVAL register. The following values were +observed immediately after writing CNVT_TVAL to 0x10000000: + + CNTVCT | CNTV_TVAL | CNTV_CVAL | CNTV_TVAL Error +--------------------+------------+--------------------+----------------- + 0x000000d4a2d8bfff | 0x10003fff | 0x000000d4b2d8bfff | +0x00004000 + 0x000000d4a2d94000 | 0x0fffffff | 0x000000d4b2d97fff | -0x00004000 + 0x000000d4a2d97fff | 0x10003fff | 0x000000d4b2d97fff | +0x00004000 + 0x000000d4a2d9c000 | 0x0fffffff | 0x000000d4b2d9ffff | -0x00004000 + +The pattern of errors in CNTV_TVAL seemed to depend on exactly which +value was written to it. For example, after writing 0x10101010: + + CNTVCT | CNTV_TVAL | CNTV_CVAL | CNTV_TVAL Error +--------------------+------------+--------------------+----------------- + 0x000001ac3effffff | 0x1110100f | 0x000001ac4f10100f | +0x1000000 + 0x000001ac40000000 | 0x1010100f | 0x000001ac5110100f | -0x1000000 + 0x000001ac58ffffff | 0x1110100f | 0x000001ac6910100f | +0x1000000 + 0x000001ac66000000 | 0x1010100f | 0x000001ac7710100f | -0x1000000 + 0x000001ac6affffff | 0x1110100f | 0x000001ac7b10100f | +0x1000000 + 0x000001ac6e000000 | 0x1010100f | 0x000001ac7f10100f | -0x1000000 + +I was also twice able to reproduce the issue covered by Allwinner's +workaround[4], that writing to TVAL sometimes fails, and both CVAL and +TVAL are left with entirely bogus values. One was the following values: + + CNTVCT | CNTV_TVAL | CNTV_CVAL +--------------------+------------+-------------------------------------- + 0x000000d4a2d6014c | 0x8fbd5721 | 0x000000d132935fff (615s in the past) + +======================================================================== + +Because the CPU can read the CNTPCT/CNTVCT registers faster than they +change, performing two reads of the register and comparing the high bits +(like other workarounds) is not a workable solution. And because the +timer can jump both forward and backward, no pair of reads can +distinguish a good value from a bad one. The only way to guarantee a +good value from consecutive reads would be to read _three_ times, and +take the middle value only if the three values are 1) each unique and +2) increasing. This takes at minimum 3 counter cycles (125 ns), or more +if an anomaly is detected. + +However, since there is a distinct pattern to the bad values, we can +optimize the common case (1022/1024 of the time) to a single read by +simply ignoring values that match the error pattern. This still takes no +more than 3 cycles in the worst case, and requires much less code. As an +additional safety check, we still limit the loop iteration to the number +of max-frequency (1.2 GHz) CPU cycles in three 24 MHz counter periods. + +For the TVAL registers, the simple solution is to not use them. Instead, +read or write the CVAL and calculate the TVAL value in software. + +Although the manufacturer is aware of at least part of the erratum[4], +there is no official name for it. For now, use the kernel-internal name +"UNKNOWN1". + +[1]: https://github.com/armbian/build/commit/a08cd6fe7ae9 +[2]: https://forum.armbian.com/topic/3458-a64-datetime-clock-issue/ +[3]: https://irclog.whitequark.org/linux-sunxi/2018-01-26 +[4]: https://github.com/Allwinner-Homlet/H6-BSP4.9-linux/blob/master/drivers/clocksource/arm_arch_timer.c#L272 + +Acked-by: Maxime Ripard <maxime.ripard@bootlin.com> +Tested-by: Andre Przywara <andre.przywara@arm.com> +Signed-off-by: Samuel Holland <samuel@sholland.org> +--- + Documentation/arm64/silicon-errata.txt | 2 + + drivers/clocksource/Kconfig | 10 +++++ + drivers/clocksource/arm_arch_timer.c | 55 ++++++++++++++++++++++++++ + 3 files changed, 67 insertions(+) + +diff --git a/Documentation/arm64/silicon-errata.txt b/Documentation/arm64/silicon-errata.txt +index 8f9577621144..4a269732d2a0 100644 +--- a/Documentation/arm64/silicon-errata.txt ++++ b/Documentation/arm64/silicon-errata.txt +@@ -44,6 +44,8 @@ stable kernels. + + | Implementor | Component | Erratum ID | Kconfig | + +----------------+-----------------+-----------------+-----------------------------+ ++| Allwinner | A64/R18 | UNKNOWN1 | SUN50I_ERRATUM_UNKNOWN1 | ++| | | | | + | ARM | Cortex-A53 | #826319 | ARM64_ERRATUM_826319 | + | ARM | Cortex-A53 | #827319 | ARM64_ERRATUM_827319 | + | ARM | Cortex-A53 | #824069 | ARM64_ERRATUM_824069 | +diff --git a/drivers/clocksource/Kconfig b/drivers/clocksource/Kconfig +index 55c77e44bb2d..d20ff4da07c3 100644 +--- a/drivers/clocksource/Kconfig ++++ b/drivers/clocksource/Kconfig +@@ -364,6 +364,16 @@ config ARM64_ERRATUM_858921 + The workaround will be dynamically enabled when an affected + core is detected. + ++config SUN50I_ERRATUM_UNKNOWN1 ++ bool "Workaround for Allwinner A64 erratum UNKNOWN1" ++ default y ++ depends on ARM_ARCH_TIMER && ARM64 && ARCH_SUNXI ++ select ARM_ARCH_TIMER_OOL_WORKAROUND ++ help ++ This option enables a workaround for instability in the timer on ++ the Allwinner A64 SoC.

This coincides with 2^56 cycles at a -timer frequency of 24 MHz, implying that the time went slightly backward -(and this was interpreted by the kernel as it jumping forward and -wrapping around past the epoch). - -Further investigation revealed instability in the low bits of CNTVCT at -the point a high bit rolls over. This leads to power-of-two cycle -forward and backward jumps. (Testing shows that forward jumps are about -twice as likely as backward jumps.) - -Without trapping reads to CNTVCT, a userspace program is able to read it -in a loop faster than it changes. A test program running on all 4 CPU -cores that reported jumps larger than 100 ms was run for 13.6 hours and -reported the following: - - Count | Event --------+--------------------------- - 9940 | jumped backward 699ms - 268 | jumped backward 1398ms - 1 | jumped backward 2097ms - 16020 | jumped forward 175ms - 6443 | jumped forward 699ms - 2976 | jumped forward 1398ms - 9 | jumped forward 356516ms - 9 | jumped forward 357215ms - 4 | jumped forward 714430ms - 1 | jumped forward 3578440ms - -This works out to a jump larger than 100 ms about every 5.5 seconds on -each CPU core. - -The largest jump (almost an hour!) was the following sequence of reads: - 0x0000007fffffffff → 0x00000093feffffff → 0x0000008000000000 - -Note that the middle bits don't necessarily all read as all zeroes or -all ones during the anomalous behavior; however the low 11 bits checked -by the function in this patch have never been observed with any other -value. - -Also note that smaller jumps are much more common, with the smallest -backward jumps of 2048 cycles observed over 400 times per second on each -core. (Of course, this is partially due to lower bits rolling over more -frequently.) Any one of these could have caused the 95 year time skip. - -Similar anomalies were observed while reading CNTPCT (after patching the -kernel to allow reads from userspace). However, the jumps are much less -frequent, and only small jumps were observed. The same program as before -(except now reading CNTPCT) observed after 72 hours: - - Count | Event --------+--------------------------- - 17 | jumped backward 699ms - 52 | jumped forward 175ms - 2831 | jumped forward 699ms - 5 | jumped forward 1398ms -Acked-by: Maxime Ripard <maxime.ripard@bootlin.com> -Tested-by: Andre Przywara <andre.przywara@arm.com> - -======================================================================== - -Because the CPU can read the CNTPCT/CNTVCT registers faster than they -change, performing two reads of the register and comparing the high bits -(like other workarounds) is not a workable solution. And because the -timer can jump both forward and backward, no pair of reads can -distinguish a good value from a bad one. The only way to guarantee a -good value from consecutive reads would be to read _three_ times, and -take the middle value iff the three values are 1) individually unique -and 2) increasing. This takes at minimum 3 cycles (125 ns), or more if -an anomaly is detected. - -However, since there is a distinct pattern to the bad values, we can -optimize the common case (2046/2048 of the time) to a single read by -simply ignoring values that match the pattern. This still takes no more -than 3 cycles in the worst case, and requires much less code. - -[1]: https://github.com/armbian/build/commit/a08cd6fe7ae9 -[2]: https://forum.armbian.com/topic/3458-a64-datetime-clock-issue/ -[3]: https://irclog.whitequark.org/linux-sunxi/2018-01-26 - -Signed-off-by: Samuel Holland <samuel@sholland.org> ---- - drivers/clocksource/Kconfig | 11 ++++++++++ - drivers/clocksource/arm_arch_timer.c | 39 ++++++++++++++++++++++++++++++++++++ - 2 files changed, 50 insertions(+) - -diff --git a/drivers/clocksource/Kconfig b/drivers/clocksource/Kconfig -index 8e8a09755d10..7a5d434dd30b 100644 ---- a/drivers/clocksource/Kconfig -+++ b/drivers/clocksource/Kconfig -@@ -364,6 +364,17 @@ config ARM64_ERRATUM_858921 - The workaround will be dynamically enabled when an affected - core is detected. - -+config SUN50I_A64_UNSTABLE_TIMER -+ bool "Workaround for Allwinner A64 timer instability" -+ default y -+ depends on ARM_ARCH_TIMER && ARM64 && ARCH_SUNXI -+ select ARM_ARCH_TIMER_OOL_WORKAROUND -+ help -+ This option enables a workaround for instability in the timer on -+ the Allwinner A64 SoC.
