2374021 Franky Lin 17 February 2016, 10:26:52 UTC brcmfmac: check for wowl support before enumerating feature flag In some cases wiphy->wowlan could be NULL if firmware doesn't have the support. Driver should check for support before walking down the feature flags.

bad7b3e Eric Anholt 04 March 2016, 20:32:07 UTC drm/vc4: Recognize a more specific compatible string for V3D. The Raspberry Pi Foundation's firmware updates are shipping device trees using the old string, so we'll keep recognizing that as this rev of V3D. Still, we should use a more specific name in the upstream DT to clarify which board is being supported, in case we do other revs of V3D in the future.

fdfd56a Eric Anholt 01 March 2016, 01:53:01 UTC drm/vc4: Respect GPIO_ACTIVE_LOW on HDMI HPD if set in the devicetree. The original Raspberry Pi had the GPIO active high, but the later models are active low. The DT GPIO bindings allow specifying the active flag, except that it doesn't get propagated to the gpiodesc, so you have to handle it yourself.

45722fe Varad Gautam 17 February 2016, 13:38:21 UTC drm/vc4: improve throughput by pipelining binning and rendering jobs The hardware provides us with separate threads for binning and rendering, and the existing model waits for them both to complete before submitting the next job. Splitting the binning and rendering submissions reduces idle time and gives us approx 20-30% speedup with some x11perf tests such as -line10 and -tilerect1. Improves openarena performance by 1.01897% +/- 0.247857% (n=16). Thanks to anholt for suggesting this. v2: Rebase on the spurious resets fix (change by anholt).

It doesn't set up chroma subsampling position (which it appears KMS doesn't deal with yet). The LBM memory is overallocated in many cases, but apparently the docs aren't quite correct and I'll probably need to look at the hardware source to really figure it out.

724f072 Eric Anholt 30 December 2015, 19:50:22 UTC drm/vc4: Add a proper short-circut path for legacy cursor updates. Previously, on every modeset we would allocate new display list memory, recompute changed planes, write all of them to the new memory, and pointed scanout at the new list (which will latch approximately at the next line of scanout). We let drm_atomic_helper_wait_for_vblanks() decide whether we needed to wait for a vblank after a modeset before cleaning up the old state and letting the next modeset proceed, and on legacy cursor updates we wouldn't wait. If you moved the cursor fast enough, we could potentially wrap around the display list memory area and overwrite the existing display list while it was still being scanned out, resulting in the HVS scanning out garbage or just halting. Instead of making cursor updates wait for scanout to move to the new display list area (which introduces significant cursor lag in X), we just rewrite our current display list.

ca61eb4 wm4 13 January 2016, 18:41:45 UTC bcm2835-pcm: Numerous enhancements bcm2835: extend allowed range of channels and samplerates Allow everything the videocore accepts. bcm2835: restrict channels*rate to 8*960000 This is required at least for SPDIF. If the bitrate goes above, videocore will either resample the audio or corrupt it due to underruns. Supposedly the hardware isn't designed to output higher rates, but it can still resample it down to supported rates. Some code is based on ac97_pcm.c. rpi: update vc_vchi_audioserv_defs.h Add audioserv 3 extensions. The changes were taken from the paste linked here: https://github.com/raspberrypi/linux/pull/1166#issuecomment-151917067 bcm2835: implement channel map API Report all layouts supported by the HDMI protocol to userspace. Make the videocore set the correct layout according to the userspace request. Some code taken from patch_hdmi.c. In particular, the HDMI channel layout table was copied without changes - with the idea in mind that hopefully it can be shared one day. Or at least updating it will be simpler. In my tests, everything appears to work, except when outputting FL FR RL RR. Then my receiver outputs RL on both the RL and RR speakers, while RR is never heard. bcm2835: access controls under the audio mutex I don't think the ALSA framework provides any kind of automatic synchronization within the control callbacks. We most likely need to ensure this manually, so add locking around all access to shared mutable data. In particular, bcm2835_audio_set_ctls() should probably always be called under our own audio lock. bcm2835: always use 2/4/8 channels for multichannel layouts Pad the unused channels with NA. This means userspace needs to write additional, silent padding channels, which is not ideal, but better than noise. Works around noise at the following channel counts: 3, 5, 6, 7 bcm2835: only allow stereo if analogue jack is selected Sending more than 2 channels to videocore while outputting to analogue mysteriously outputs heavy artifacts. So just paint it over with a hack: if analogue is explicitly selected as destination, do not reporting support for anything other than stereo. I'm not sure how to deal with the auto case (destination 0). There's probably way to retrieve this and even to listen to plug events, but I didn't find one yet, and it's probably not worth the trouble. Just don't use this setting, I guess. Unless you like noise. Changing the setting while an audio stream is active also doesn't work properly. We could probably interrupt running streams by returning ENODEV or using kernel hotplug stuff (maybe), but that also doesn't seem worth the trouble. bcm2835: interpolate audio delay It appears the GPU only sends us a message all 10ms to update the playback progress. Other than this, the playback position (what SNDRV_PCM_IOCTL_DELAY will return) is not updated at all. Userspace will see jitter up to 10ms in the audio position. Make this a bit nicer for userspace by interpolating the position using the CPU clock. I'm not sure if setting snd_pcm_runtime.delay is the right approach for this. Or if there is maybe an already existing mechanism for position interpolation in the ALSA core. I only set SNDRV_PCM_INFO_BATCH because this appears to remove at least one situation snd_pcm_runtime.delay is used, so I have to worry less in which place I have to update this field, or how it interacts with the rest of ALSA. In the future, it might be nice to use VC_AUDIO_MSG_TYPE_LATENCY. One problem is that it requires sending a videocore message, and waiting for a reply, which could make the implementation much harder due to locking and synchronization requirements. 08 June 2016, 12:30:02 UTC

The built-in RPi adaptor will still get a MAC address based on the parameter passed on the command line as the RPi hardware does not have an eeprom, however usb->ethernet adaptors using the same driver should have an eeprom with MAC address as part of their hardware and therefore will use this meaning they don't end up with the same MAC address as the built-in RPi adaptor. 08 June 2016, 12:29:58 UTC
b736ec0 Michael Lange 21 January 2016, 17:10:16 UTC rtc: ds1307: add support for the DT property 'wakeup-source' For RTC chips with no IRQ directly connected to the SoC, the RTC chip can be forced as a wakeup source by stating that explicitly in the device's .dts file using the "wakeup-source" boolean property. This will guarantee the 'wakealarm' sysfs entry is available on the device, if supported by the RTC. With these changes to the driver rtc-ds1307 and the necessary entries in the .dts file, I get an working ds1337 RTC on the Witty Pi extension board by UUGear for the Raspberry Pi. An example for the entry in the .dts file: rtc: ds1337@68 { compatible = "dallas,ds1337"; reg = <0x68>; wakeup-source; If the "wakeup-source" property is set, do not request an IRQ.

2b8ff28 Phil Elwell 25 June 2015, 11:16:11 UTC gpio-poweroff: Allow it to work on Raspberry Pi The Raspberry Pi firmware manages the power-down and reboot process. To do this it installs a pm_power_off handler, causing the gpio-poweroff module to abort the probe function. This patch introduces a "force" DT property that overrides that behaviour, and also adds a DT overlay to enable and control it. Note that running in an active-low configuration (DT parameter "active_low") requires a custom dt-blob.bin and probably won't allow a reboot without switching off, so an external inversion of the trigger signal may be preferable. 08 June 2016, 12:29:54 UTC

This is to support the Raspberry Pi PWR LED, which is driven by external hardware in normal use. N.B. pwr_led is not available on Model A or B boards. leds-gpio: Implement the brightness_get method The power LED uses some clever logic that means it is driven by a voltage measuring circuit when configured as input, otherwise it is driven by the GPIO output value. This patch wires up the brightness_get method for leds-gpio so that user-space can monitor the LED value via /sys/class/gpio/led1/brightness. Using the input trigger this returns an indication of the system power health, otherwise it is just whatever value the trigger has written most recently.

The HiFiBerry DAC+ and DAC+ Pro products both use the existing bcm sound driver with the DAC+ Pro having a special clock device driver representing the two high precision oscillators. An addition bug fix is included for the PCM512x codec where by the physical size of the sample frame is used in the calculation of the LRCK divisor as it was found to be wrong when using 24-bit depth sample contained in a little endian 4-byte sample frame. Limit PCM512x "Digital" gain to 0dB by default with HiFiBerry DAC+ 24db_digital_gain DT param can be used to specify that PCM512x codec "Digital" volume control should not be limited to 0dB gain, and if specified will allow the full 24dB gain. 08 June 2016, 12:29:50 UTC

At 192kHz only 128xfs is supported. The existing driver selects 128xfs automatically for some lower samples rates. By using an additional mclk_div divider, it is now possible to control the behaviour. This allows using 256xfs PLL frequency on all sample rates up to 96kHz. It should allow lower jitter and better signal quality. The behavior has to be controlled by the sound card driver, because some sample frequency share the same setting. e.g. 192kHz and 96kHz use 24.576MHz master clock. The only difference is the MCLK divider. This also added support for 32bit data. Signed-off-by: Daniel Matuschek <daniel@matuschek.net> 08 June 2016, 12:29:47 UTC

cba475f Harm Hanemaaijer 20 June 2013, 18:21:39 UTC Speed up console framebuffer imageblit function Especially on platforms with a slower CPU but a relatively high framebuffer fill bandwidth, like current ARM devices, the existing console monochrome imageblit function used to draw console text is suboptimal for common pixel depths such as 16bpp and 32bpp. The existing code is quite general and can deal with several pixel depths. By creating special case functions for 16bpp and 32bpp, by far the most common pixel formats used on modern systems, a significant speed-up is attained which can be readily felt on ARM-based devices like the Raspberry Pi and the Allwinner platform, but should help any platform using the fb layer. The special case functions allow constant folding, eliminating a number of instructions including divide operations, and allow the use of an unrolled loop, eliminating instructions with a variable shift size, reducing source memory access instructions, and eliminating excessive branching. These unrolled loops also allow much better code optimization by the C compiler. The code that selects which optimized variant is used is also simplified, eliminating integer divide instructions. The speed-up, measured by timing 'cat file.txt' in the console, varies between 40% and 70%, when testing on the Raspberry Pi and Allwinner ARM-based platforms, depending on font size and the pixel depth, with the greater benefit for 32bpp. Signed-off-by: Harm Hanemaaijer <fgenfb@yahoo.com> 08 June 2016, 12:29:43 UTC

daded01 Phil Elwell 11 May 2015, 08:00:42 UTC scripts: Add mkknlimg and knlinfo scripts from tools repo The Raspberry Pi firmware looks for a trailer on the kernel image to determine whether it was compiled with Device Tree support enabled. If the firmware finds a kernel without this trailer, or which has a trailer indicating that it isn't DT-capable, it disables DT support and reverts to using ATAGs. The mkknlimg utility adds that trailer, having first analysed the image to look for signs of DT support and the kernel version string. knlinfo displays the contents of the trailer in the given kernel image. scripts/mkknlimg: Add support for ARCH_BCM2835 Add a new trailer field indicating whether this is an ARCH_BCM2835 build, as opposed to MACH_BCM2708/9. If the loader finds this flag is set it changes the default base dtb file name from bcm270x... to bcm283y... Also update knlinfo to show the status of the field. scripts/mkknlimg: Improve ARCH_BCM2835 detection The board support code contains sufficient strings to be able to distinguish 2708 vs. 2835 builds, so remove the check for bcm2835-pm-wdt which could exist in either. Also, since the canned configuration is no longer built in (it's a module), remove the config string checking. See: https://github.com/raspberrypi/linux/issues/1157 08 June 2016, 12:29:41 UTC

16f115c popcornmix 17 June 2015, 14:44:08 UTC Add Chris Boot's i2c driver i2c-bcm2708: fixed baudrate Fixed issue where the wrong CDIV value was set for baudrates below 3815 Hz (for 250MHz bus clock). In that case the computed CDIV value was more than 0xffff. However the CDIV register width is only 16 bits. This resulted in incorrect setting of CDIV and higher baudrate than intended. Example: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0x1704 -> 42430Hz After correction: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0xffff -> 3815Hz The correct baudrate is shown in the log after the cdiv > 0xffff correction. Perform I2C combined transactions when possible Perform I2C combined transactions whenever possible, within the restrictions of the Broadcomm Serial Controller. Disable DONE interrupt during TA poll Prevent interrupt from being triggered if poll is missed and transfer starts and finishes. i2c: Make combined transactions optional and disabled by default i2c: bcm2708: add device tree support Add DT support to driver and add to .dtsi file.

Add a module parameter to allow the user to set it explicitly. Signed-off-by: Julian Scheel <julian@jusst.de> lirc-rpi: Use the higher-level irq control functions This module used to access the irq_chip methods of the gpio controller directly, rather than going through the standard enable_irq/irq_set_irq_type functions. This caused problems on pinctrl-bcm2835 which only implements the irq_enable/disable methods and not irq_unmask/mask. lirc-rpi: Correct the interrupt usage 1) Correct the use of enable_irq (i.e. don't call it so often) 2) Correct the shutdown sequence. 3) Avoid a bcm2708_gpio driver quirk by setting the irq flags earlier lirc-rpi: use getnstimeofday instead of read_current_timer read_current_timer isn't guaranteed to return values in microseconds, and indeed it doesn't on a Pi2. Issue: linux#827 lirc-rpi: Add device tree support, and a suitable overlay The overlay supports DT parameters that match the old module parameters, except that gpio_in_pull should be set using the strings "up", "down" or "off". lirc-rpi: Also support pinctrl-bcm2835 in non-DT mode 08 June 2016, 12:29:37 UTC

c4a348f Tim Gover 22 July 2014, 14:41:04 UTC vcsm: VideoCore shared memory service for BCM2835 Add experimental support for the VideoCore shared memory service. This allows user processes to allocate memory from VideoCore's GPU relocatable heap and mmap the buffers. Additionally, the memory handles can passed to other VideoCore services such as MMAL, OpenMax and DispmanX TODO * This driver was originally released for BCM28155 which has a different cache architecture to BCM2835. Consequently, in this release only uncached mappings are supported. However, there's no fundamental reason which cached mappings cannot be support or BCM2835 * More refactoring is required to remove the typedefs. * Re-enable the some of the commented out debug-fs statistics which were disabled when migrating code from proc-fs. * There's a lot of code to support sharing of VCSM in order to support Android. This could probably done more cleanly or perhaps just removed.
