Let's use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi as base files for our dts files. Mainline dts files are based on these files: bcm2835-rpi.dtsi bcm2835.dtsi bcm2836.dtsi bcm283x.dtsi Current downstream are based on these: bcm2708.dtsi bcm2709.dtsi bcm2710.dtsi bcm2708_common.dtsi This patch introduces this dependency: bcm2708.dtsi bcm2709.dtsi bcm2708-rpi.dtsi bcm270x.dtsi bcm2835.dtsi bcm2836.dtsi bcm283x.dtsi And: bcm2710.dtsi bcm2708-rpi.dtsi bcm270x.dtsi bcm283x.dtsi bcm270x.dtsi contains the downstream bcm283x.dtsi diff. bcm2708-rpi.dtsi is the downstream version of bcm2835-rpi.dtsi. Other changes: - The led node has moved from /soc/leds to /leds. This is not a problem since the label is used to reference it. - The clk_osc reg property changes from 6 to 3. - The gpu nodes has their interrupt property set in the base file. - the clocks label does not point to the /clocks node anymore, but points to the cprman node. This is not a problem since the overlays that use the clock node refer to it directly: target-path = "/clocks"; - some nodes now have 2 labels since mainline and downstream differs in this respect: cprman/clocks, spi0/spi, gpu/vc4. - some nodes doesn't have an explicit status = "okay" since they're not disabled in the base file: watchdog and random. - gpiomem doesn't need an explicit status = "okay". - bcm2708-rpi-cm.dts got the hpd-gpios property from bcm2708_common.dtsi, it's now set directly in that file. - bcm2709-rpi-2-b.dts has the timer node moved from /soc/timer to /timer. - Removed clock-frequency property on the bcm{2709,2710}.dtsi timer nodes.

| 3e6548d | Matt Flax | 16 May 2016, 11:36:31 UTC | New AudioInjector.net Pi soundcard with low jitter audio in and out. Contains the sound/soc/bcm ALSA machine driver and necessary alterations to the Kconfig and Makefile. Adds the dts overlay and updates the Makefile and README. Updates the relevant defconfig files to enable building for the Raspberry Pi. Thanks to Phil Elwell (pelwell) for the review, simple-card concepts and discussion. Thanks to Clive Messer for overlay naming suggestions. Added support for headphones, microphone and bclk_ratio settings. This patch adds headphone and microphone capability to the Audio Injector sound card. The patch also sets the bit clock ratio for use in the bcm2835-i2s driver. The bcm2835-i2s can't handle an 8 kHz sample rate when the bit clock is at 12 MHz because its register is only 10 bits wide which can't represent the ch2 offset of 1508. For that reason, the rate constraint is added. | 08 January 2017, 11:40:17 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 January 2017, 11:40:05 UTC |

| f6219b5 | 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 January 2017, 11:39:55 UTC |

| d9edb91 | 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 scripts: Multi-platform support for mkknlimg and knlinfo The firmware uses tags in the kernel trailer to choose which dtb file to load. Current firmware loads bcm2835-*.dtb if the '283x' tag is true, otherwise it loads bcm270*.dtb. This scheme breaks if an image supports multiple platforms. This patch adds '270X' and '283X' tags to indicate support for RPi and upstream platforms, respectively. '283x' (note lower case 'x') is left for old firmware, and is only set if the image only supports upstream builds. scripts/mkknlimg: Append a trailer for all input Now that the firmware assumes an unsigned kernel is DT-capable, it is helpful to be able to mark a kernel as being non-DT-capable.

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.

With these patches, calls to vchiq_close_service and vchiq_remove_service won't return until any associated callbacks have been delivered to the callback thread. VCHIQ: Add per-service tracing The new service option VCHIQ_SERVICE_OPTION_TRACE is a boolean that toggles tracing for the specified service. This commit also introduces vchi_service_set_option and the associated option VCHI_SERVICE_OPTION_TRACE. vchiq: Make the synchronous-CLOSE logic more tolerant vchiq: Move logging control into debugfs vchiq: Take care of a corner case tickled by VCSM Closing a connection that isn't fully open requires care, since one side does not know the other side's port number. Code was present to handle the case where a CLOSE is sent immediately after an OPEN, i.e. before the OPENACK has been received, but this was incorrectly being used when an OPEN from a client using port 0 was rejected. (In the observed failure, the host was attempting to use the VCSM service, which isn't present in the 'cutdown' firmware. The failure was intermittent because sometimes the keepalive service would grab port 0.) This case can be distinguished because the client's remoteport will still be VCHIQ_PORT_FREE, and the srvstate will be OPENING.

The existence of this parameter guarantees that the kernel is capable, and the parameter will only be modified from the safe default if the loader is capable. 2) Flush/invalidate vmalloc'd memory, and invalidate after reads vchiq: fix NULL pointer dereference when closing driver The following code run as root will cause a null pointer dereference oops: int fd = open("/dev/vc-cma", O_RDONLY); if (fd < 0) err(1, "open failed"); (void)close(fd); [ 1704.877721] Unable to handle kernel NULL pointer dereference at virtual address 00000000 [ 1704.877725] pgd = b899c000 [ 1704.877736] [00000000] *pgd=37fab831, *pte=00000000, *ppte=00000000 [ 1704.877748] Internal error: Oops: 817 [#1] PREEMPT SMP ARM [ 1704.877765] Modules linked in: evdev i2c_bcm2708 uio_pdrv_genirq uio [ 1704.877774] CPU: 2 PID: 3656 Comm: stress-ng-fstat Not tainted 3.19.1-12-generic-bcm2709 #12-Ubuntu [ 1704.877777] Hardware name: BCM2709 [ 1704.877783] task: b8ab9b00 ti: b7e68000 task.ti: b7e68000 [ 1704.877798] PC is at __down_interruptible+0x50/0xec [ 1704.877806] LR is at down_interruptible+0x5c/0x68 [ 1704.877813] pc : [<80630ee8>] lr : [<800704b0>] psr: 60080093 sp : b7e69e50 ip : b7e69e88 fp : b7e69e84 [ 1704.877817] r10: b88123c8 r9 : 00000010 r8 : 00000001 [ 1704.877822] r7 : b8ab9b00 r6 : 7fffffff r5 : 80a1cc34 r4 : 80a1cc34 [ 1704.877826] r3 : b7e69e50 r2 : 00000000 r1 : 00000000 r0 : 80a1cc34 [ 1704.877833] Flags: nZCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment user [ 1704.877838] Control: 10c5387d Table: 3899c06a DAC: 00000015 [ 1704.877843] Process do-oops (pid: 3656, stack limit = 0xb7e68238) [ 1704.877848] Stack: (0xb7e69e50 to 0xb7e6a000) [ 1704.877856] 9e40: 80a1cc3c 00000000 00000010 b88123c8 [ 1704.877865] 9e60: b7e69e84 80a1cc34 fff9fee9 ffffffff b7e68000 00000009 b7e69ea4 b7e69e88 [ 1704.877874] 9e80: 800704b0 80630ea4 fff9fee9 60080013 80a1cc28 fff9fee9 b7e69edc b7e69ea8 [ 1704.877884] 9ea0: 8040f558 80070460 fff9fee9 ffffffff 00000000 00000000 00000009 80a1cb7c [ 1704.877893] 9ec0: 00000000 80a1cb7c 00000000 00000010 b7e69ef4 b7e69ee0 803e1ba4 8040f514 [ 1704.877902] 9ee0: 00000e48 80a1cb7c b7e69f14 b7e69ef8 803e1c9c 803e1b74 b88123c0 b92acb18 [ 1704.877911] 9f00: b8812790 b8d815d8 b7e69f24 b7e69f18 803e2250 803e1bc8 b7e69f5c b7e69f28 [ 1704.877921] 9f20: 80167bac 803e222c 00000000 00000000 b7e69f54 b8ab9ffc 00000000 8098c794 [ 1704.877930] 9f40: b8ab9b00 8000efc4 b7e68000 00000000 b7e69f6c b7e69f60 80167d6c 80167b28 [ 1704.877939] 9f60: b7e69f8c b7e69f70 80047d38 80167d60 b7e68000 b7e68010 8000efc4 b7e69fb0 [ 1704.877949] 9f80: b7e69fac b7e69f90 80012820 80047c84 01155490 011549a8 00000001 00000006 [ 1704.877957] 9fa0: 00000000 b7e69fb0 8000ee5c 80012790 00000000 353d8c0f 7efc4308 00000000 [ 1704.877966] 9fc0: 01155490 011549a8 00000001 00000006 00000000 00000000 76cf3ba0 00000003 [ 1704.877975] 9fe0: 00000000 7efc42e4 0002272f 76e2ed66 60080030 00000003 00000000 00000000 [ 1704.877998] [<80630ee8>] (__down_interruptible) from [<800704b0>] (down_interruptible+0x5c/0x68) [ 1704.878015] [<800704b0>] (down_interruptible) from [<8040f558>] (vchiu_queue_push+0x50/0xd8) [ 1704.878032] [<8040f558>] (vchiu_queue_push) from [<803e1ba4>] (send_worker_msg+0x3c/0x54) [ 1704.878045] [<803e1ba4>] (send_worker_msg) from [<803e1c9c>] (vc_cma_set_reserve+0xe0/0x1c4) [ 1704.878057] [<803e1c9c>] (vc_cma_set_reserve) from [<803e2250>] (vc_cma_release+0x30/0x38) [ 1704.878069] [<803e2250>] (vc_cma_release) from [<80167bac>] (__fput+0x90/0x1e0) [ 1704.878082] [<80167bac>] (__fput) from [<80167d6c>] (____fput+0x18/0x1c) [ 1704.878094] [<80167d6c>] (____fput) from [<80047d38>] (task_work_run+0xc0/0xf8) [ 1704.878109] [<80047d38>] (task_work_run) from [<80012820>] (do_work_pending+0x9c/0xc4) [ 1704.878123] [<80012820>] (do_work_pending) from [<8000ee5c>] (work_pending+0xc/0x20) [ 1704.878133] Code: e50b1034 e3a01000 e50b2030 e580300c (e5823000) ..the fix is to ensure that we have actually initialized the queue before we attempt to push any items onto it.

We occasionally found a duplicate message from 16 messages prior, resulting in a buffer returned twice. While only one thread adds completions, without the mutex you don't get the protection of the automatic memory barrier you get with synchronisation objects.

Signed-off-by: Noralf Trønnes <noralf@tronnes.org> 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. snd-bcm2835: Don't allow responses from VC to be interrupted by user signals There should always be a response, and retry after a signal interruption is not handled, so don't report we are interruptible.
