From c0a36f08f4241538368c0ceafd0aa07a0e57b47e Mon Sep 17 00:00:00 2001 From: Archana Patni Date: Mon, 19 May 2014 12:19:00 +0100 Subject: iio: hid-sensors: Get feature report from sensor hub after changing power state Some sensor hubs require a get feature report call to be issued soon after changing the power state of the sensor. Without this, the sensor remains in the current state. This patch adds a call soon after the power state. This is retained as a generic call across all sensor hubs since the behavior has been noticed on more than one implementation.

This exposes a bug in the AS3722 regulator driver which fails to read the voltage of disabled regulators. The reason is that the hardware is programmed to a selector of 0, but none of the voltage tables include 0 as a valid selector. The datasheets indicate that 0 is a valid selector when the regulators are powered off. To fix this, add a range including selector 0 to the voltage tables.

Which means if something unregistered the boot vt driver (e.g. i915.ko kicking out vga_con) there's nothing left when trying to unbind e.g. fbcon through sysfs. But in most cases have the dummy console hanging around besides the boot console, so this test is fairly dubious. What we actually want is simply a different console than the one we want to unbind. v2: Correct the commit message to clarify that the dummy console isn't always around, but only in most cases (David).

If the pipe is disable but some SDVO outputs are active, we may end up dividing by zero in intel_sdvo_get_config(). To avoid the problem simply check for zero pixel_multiplier and skip the division. Another attempt at fixing this involved populating pixel_multiplier to 1 even for disabled pipes, but that triggered a WARN because SDVO_CMD_GET_CLOCK_RATE_MULT command failed and thus encoder_pixel_multiplier was left at zero and didn't match pipe_config->pixel_multiplier.

But, it differs from standard SMBus protocol on several aspects: - it supports only one slave device, and thus drop the address field - it adds a parity bit every 8bits of data - only one read access is required to read a byte (instead of a write followed by a read access in standard SMBus protocol) - there's no Ack bit after each byte transfer This means this bus cannot be used to interface with standard SMBus devices (the only known device to support this interface is the AXP221 PMIC). However the P2WI protocol is close enough to SMBus to be integrated in the I2C subsystem (see this thread [1] for detailed reasons that led to integrating this driver in the I2C subsystem).

In that case, "have_bytes - reserved" goes negative, and since size_t is unsigned, the expression: ibytes = min_t(size_t, ibytes, have_bytes - reserved); ... does not do the right thing. This is rather bad, because it defeats the catastrophic reseeding feature in the xfer_secondary_pool() path. It also can cause the "BUG: spinlock trylock failure on UP" for some kernel configurations when prandom_reseed() calls get_random_bytes() in the early init, since when the entropy count gets corrupted, credit_entropy_bits() erroneously believes that the nonblocking pool has been fully initialized (when in fact it is not), and so it calls prandom_reseed(true) recursively leading to the spinlock BUG. The logic is *not* the same it was originally, but in the cases where it matters, the behavior is the same, and the resulting code is hopefully easier to read and understand.

Meanwhile, HD-audio tries to bind wth i915 just by request_symbol() without knowing that the initialization was skipped, and eventually it hits WARN_ON() in i915_request_power_well() and i915_release_power_well() wrongly but still continues probing, even though it doesn't work at all.

Bad reviewing on my part, sorry. The right fix is to either make qemu change its endian when the guest changes endian (working on that) or to use the existing foreign endian support.

The problem is that while there are inline wrappers to turn the thermal API calls into empty functions, those do not help if the cpu-thermal driver is a loadable module and cpufreq-cpu0 is builtin. Since CONFIG_CPU_THERMAL is a bool option that decides whether the cpu code is built into the thermal module or not, we have to use a dependency on the thermal driver itself. However, if CPU_THERMAL is disabled, we don't need the dependency, hence the strange '!CPU_THERMAL || THERMAL' construct.

The port must still be allowed to carry out runtime pm callbacks and receive a -EAGAIN or -EBUSY result. Otherwise the usb_port device will transition to the pm error state and trigger the same for the child usb_device. Prior to the offending commit usb_hub_create_port_device() arranged for runtime pm to be disabled is dev_pm_qos_expose_flags() failed. Instead, force the default state of PM_QOS_FLAG_NO_POWER_OFF flag to be set prior to enabling runtime pm. If that policy can not be set then fail registration.

This definitely sounds like a bug in the BIOS, but at the moment there is no way to fix it. This patch works around the problem by avoiding the handoff whenever the motherboard and BIOS version match those of Leandro's computer.

This happens because the read_status_mask masks out the BI condition, which uart_insert_char() then interprets as a normal 0x00 byte. SUS v3 is clear regarding the meaning of IGNBRK; Section 11.2.2, General Terminal Interface - Input Modes, states: "If IGNBRK is set, a break condition detected on input shall be ignored; that is, not put on the input queue and therefore not read by any process." Fix read_status_mask to include the BI bit if IGNBRK is set; the lsr status retains the BI bit if a BREAK is recv'd, which is subsequently ignored in uart_insert_char() when masked with the ignore_status_mask.

This means parity errors should not be received from the tty driver, and the data received should be treated normally. SUS v3, 11.2.2, General Terminal Interface - Input Modes, states: "If INPCK is set, input parity checking shall be enabled. If INPCK is not set, input parity checking shall be disabled, allowing output parity generation without input parity errors. Note that whether input parity checking is enabled or disabled is independent of whether parity detection is enabled or disabled (see Control Modes). If parity detection is enabled but input parity checking is disabled, the hardware to which the terminal is connected shall recognize the parity bit, but the terminal special file shall not check whether or not this bit is correctly set." Ignore parity errors reported by the tty driver when INPCK is not set, and handle the received data normally.

This resulted in the baud rate changing when switching consoles during boot. This feature allows specifying a single console option on the kernel command line rather than both an early console and regular serial tty console. It would be nice to generalize this feature. However, it only works if the correct baud rate can be probed early which is not the case on many platforms which have non-standard UART clock rates. So for now, this is left as an 8250 specific feature.
