| | | | | | | | | | | | | | | | | On the Nyan EC, we almost run out of the stack of console task. Instead of making that struct static or global, we print the cached data.

* cortex-m: store FPU regs on context switchAlec Berg2014-04-183-14/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added storing of FPU regs on context switches when CONFIG_FPU is defined. On context switches, EXC_RETURN[4] is checked in order to tell which tasks have used floating point and which have not. The FPU regs are only stored on task stacks for tasks that use the floating point. Tasks that use floating point will therefore require roughly an additional 128 bytes of stack space, and context switches will take about 32 clock cycles longer for each task involved in the switch that uses FP. For tasks that don't use floating point, the stack usage actually decreases by 64 bytes because previously we were reserving stack space for FPU regs S0-S15 on every context switch for every task, even though we weren't doing anything with them. If a task only uses the FPU for a brief window, it can call task_clear_fp_used() in order to clear the FP used bit so that context switches using that task will not backup FP regs anymore. BUG=chrome-os-partner:27971 BRANCH=none TEST=Tested on glimmer and peppy. Added the following code, which uses the FPU in both the hooks task and the console task. Note, I tested this for a handful of registers, notably registers in the group s0-s15 which are backed up by lazy stacking, and registers in the group s16-s31 which are backed up manually. float dummy = 2.0f; static void hook_fpu(void) { union { float f; int i; } tmp; /* do a dummy FP calculation to set CONTROL.FPCA high. */ dummy = 2.3f*7.8f; /* read and print FP reg. */ asm volatile("vmov %0, s29" : "=r"(tmp.f)); ccprintf("Hook float 0x%08x\n", tmp.i); /* write FP reg. */ tmp.i = 0x1234; asm volatile("vmov s29, %0" : : "r"(tmp.f)); } DECLARE_HOOK(HOOK_SECOND, hook_fpu, HOOK_PRIO_DEFAULT); static int command_fpu_test(int argc, char **argv) { union { float f; int i; } tmp; /* do a dummy FP calculation to set CONTROL.FPCA high. */ dummy = 2.7f*7.8f; /* read and print FP reg. */ asm volatile("vmov %0, s29" : "=r"(tmp.f)); ccprintf("Console float 0x%08x\n", tmp.i); if (argc == 2) { char *e; tmp.i = strtoi(argv[1], &e, 0); if (*e) return EC_ERROR_PARAM1; /* write FP reg. */ asm volatile("vmov s29, %0" : : "r"(tmp.f)); } else { task_clear_fp_used(); } return EC_SUCCESS; } DECLARE_CONSOLE_COMMAND(fputest, command_fpu_test, "", "", NULL); When you call fputest 5 from EC console before this CL, then on the next HOOK_SECOND, the value of register s29 is 5, instead of 0x1234 because register s29 is not saved on context switches: Hook float 0x00001234 > fputest 5 Console float 0x00001234 Hook float 0x00000005 When this CL is in use, the register holds the correct value for each task: Hook float 0x00001234 > fputest 5 Console float 0x00001234 Hook float 0x00001234 > fputest Console float 0x00000005 Hook float 0x00001234 Change-Id: Ifb1b5cbf1c6fc9193f165f8d69c96443b35bf981 Signed-off-by: Alec Berg <alecaberg@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/194949 Reviewed-by: Vincent Palatin <vpalatin@chromium.org>
* lpc: ACPI query-next-event drops masked eventsRandall Spangler2014-04-172-6/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, you could use EC_CMD_ACPI_QUERY_EVENT to read events that were masked off (that is, events which would not generate SCI/SMI/wake signals). The handlers for those signals on the host would still act on the masked-off events - for example, causing unwanted power button keypresses/releases. Now, EC_CMD_ACPI_QUERY_EVENT will only return events which are unmasked. This does not affect storing of events at event generation time. Events are still queued; they won't be dropped until the host attempts to read the next event. This gives the host a chance to set a mask later in boot (but before querying any events) to capture events which happened early in the boot process. BUG=chrome-os-partner:26574 BRANCH=rambi TEST=At EC console, type 'hostevent set 0x80' but don't press enter. Hold down the power button; UI starts fading to white.

Sub-commands created include: dump: dumps all current motion sensor data info: returns general information about each motion sensor ec_rate: set/get the EC sampling rate of sensors sensor_range: set/get the sensor range (ie +/- 2G,4G,8G) sensor_odr: set/get the sensor output data rate (ie 50Hz, 100Hz, ...) For sensor_range and sensor_odr parameters, since the host doesn't know what are valid values for the parameter, the host can specify to round up or down to the nearest valid value. For example, the host can specify to set the output data rate to at least 100Hz, and the EC will return the closest valid output data rate that is at least 100Hz.

* Retry 8042 keyboard interrupts if host isn't respondingRandall Spangler2014-04-051-2/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the host somehow fails to see an edge on the keyboard IRQ line, it won't read the 8042 data register. The EC won't ever send another IRQ, because it only does so after filling the register. So the keyboard will hang. Work around this with a retry mechanism. If the AP hasn't responded after 3 additional keyboard events, generate another IRQ. So a stuck key will get unstuck if you tap it a few times. That's reasonable, and matches what people do already if they have a sticky key due to crud accumulating in the keyboard. I've tested this when the system is booted to the OS. I don't see any additional IRQs generated on the EC console ("KB extra IRQ"), so the host is keeping up with the keyboard input stream. If I'm in dev or recovery mode and bang on the keyboard right after powering the system on (when the BIOS isn't yet paying attention to the keyboard), I can see extra IRQs generated. This shows the retry mechanism is working. The extra IRQs have no negative effect on the boot process, and the keyboard works normally when the OS does eventually boot.

* lm4: Ensure falling edges on outputs to edge-sensitive host inputsRandall Spangler2014-04-041-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The KBD_IRQ#, SMI#, and SCI# lines on the host are sensitive to falling edges. When generating an interrupt, wait long enough to make sure the lines are high before pulling them low, so that it reliably generates a falling edge. This solves a problem where calling the IRQ-generation function twice in rapid succession could cause two low pulses without an intervening logic-high as seen by the host (and thus not a falling edge as seen by the host). This is most visible on the keyboard line, because it can generate back-to-back events on multi-byte scan codes. Once the keyboard mailbox is full, the EC will never attempt to fill it, and thus it also won't attempt to generate another keyboard IRQ. And since the host missed the IRQ, it doesn't know it needs to empty the mailbox. It could theoretically happen for the other lines, so fix them now just to be safe. This change should be low-impact and free from side effects. 4 usec is a very small additional delay. Even 65 usec added delay for SCI/SMI is small, given that SCI/SMI events are typically much less frequent (if they're happening very frequently, something else is tragically wrong with the system...)
