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. --- diff --git a/target/linux/brcm2708/patches-4.4/0413-IQaudIO-auto-mute-for-AMP-and-DigiAMP.patch b/target/linux/brcm2708/patches-4.4/0412-IQaudIO-auto-mute-for-AMP-and-DigiAMP.patch index 1e6f65a..7636883 100644 --- a/target/linux/brcm2708/patches-4.4/0413-IQaudIO-auto-mute-for-AMP-and-DigiAMP.patch +++ b/target/linux/brcm2708/patches-4.4/0412-IQaudIO-auto-mute-for-AMP-and-DigiAMP.patch @@ -1,7 +1,7 @@ -From c5368041bdadf28f7081deb6e11c9aaafe05377f Mon Sep 17 00:00:00 2001 +From 98f0214603229df4038cc0d318111a37b10078a1 Mon Sep 17 00:00:00 2001 From: DigitalDreamtime <clive.messer@digitaldreamtime.co.uk> Date: Mon, 9 May 2016 20:38:08 +0100 -Subject: [PATCH 413/423] IQaudIO: auto-mute for AMP+ and DigiAMP+ +Subject: [PATCH] IQaudIO: auto-mute for AMP+ and DigiAMP+ IQAudIO amplifier mute via GPIO22.

This would cause +flip completion handling only at the next vblank - one +frame too late. + +In vc4_crtc_handle_page_flip() check the actual DL head +pointer in SCALER_DISPLACTX against the requested pointer +for page flip to make sure that the flip actually really +completed in the current vblank and doesn't get deferred +to the next one because the DL head pointer was written +a bit too late into SCALER_DISPLISTX, after start of +vblank, and missed the boat. This avoids handling a +pageflip completion too early - one frame too early. + +According to Eric, DL head pointer updates which were +written into the HVS DISPLISTX reg get committed to hardware +at the last pixel of active scanout.

On VC4 the +pixelvalves PV do not have a scanout position +register. Only the hardware video scaler HVS has a +similar register which describes which scanline for +the output is currently composited and stored in the +HVS fifo for later consumption by the PV. + +This causes a problem in that the HVS runs at a much +faster clock (system clock / audio gate) than the PV +which runs at video mode dot clock, so the unless the +fifo between HVS and PV is full, the HVS will progress +faster in its observable read line position than video +scan rate, so the HVS position reading can't be directly +translated into a scanout position for timestamp correction. + +Additionally when the PV is in vblank, it doesn't consume +from the fifo, so the fifo gets full very quickly and then +the HVS stops compositing until the PV enters active scanout +and starts consuming scanlines from the fifo again, making +new space for the HVS to composite. + +Therefore a simple translation of HVS read position into +elapsed time since (or to) start of active scanout does +not work, but for the most interesting cases we can still +get useful and sufficiently accurate results: + +1. The PV enters active scanout of a new frame with the + fifo of the HVS completely full, and the HVS can refill + any fifo line which gets consumed and thereby freed up by + the PV during active scanout very quickly. Therefore the + PV and HVS work effectively in lock-step during active + scanout with the fifo never having more than 1 scanline + freed up by the PV before it gets refilled. The PV's + real scanout position is therefore trailing the HVS + compositing position as scanoutpos = hvspos - fifosize + and we can get the true scanoutpos as HVS readpos minus + fifo size, so precise timestamping works while in active + scanout, except for the last few scanlines of the frame, + when the HVS reaches end of frame, stops compositing and + the PV catches up and drains the fifo. This special case + would only introduce minor errors though. + +2. If we are in vblank, then we can only guess something + reasonable. If called from vblank irq, we assume the irq is + usually dispatched with minimum delay, so we can take a + timestamp taken at entry into the vblank irq handler as a + baseline and then add a full vblank duration until the + guessed start of active scanout. As irq dispatch is usually + pretty low latency this works with relatively low jitter and + good results. + + If we aren't called from vblank then we could be anywhere + within the vblank interval, so we return a neutral result, + simply the current system timestamp, and hope for the best. + +Measurement shows the generated timestamps to be rather precise, +and at least never off more than 1 vblank duration worst-case. + +Limitations: Doesn't work well yet for interlaced video modes, + therefore disabled in interlaced mode for now. + +v2: Use the DISPBASE registers to determine the FIFO size (changes + by anholt) + +Signed-off-by: Mario Kleiner <mario.kleiner.de@gmail.com> +Signed-off-by: Eric Anholt <eric@anholt.net> +Reviewed-and-tested-by: Mario Kleiner <mario.kleiner.de@gmail.com> (v2) +(cherry picked from commit 1bf59f1dcbe25272f6b5d870054647e58a8a9c55) +--- + drivers/gpu/drm/vc4/vc4_crtc.c | 162 +++++++++++++++++++++++++++++++++++++++++ + drivers/gpu/drm/vc4/vc4_drv.c | 2 + + drivers/gpu/drm/vc4/vc4_drv.h | 7 ++ + drivers/gpu/drm/vc4/vc4_regs.h | 22 +++++- + 4 files changed, 192 insertions(+), 1 deletion(-) + +--- a/drivers/gpu/drm/vc4/vc4_crtc.c ++++ b/drivers/gpu/drm/vc4/vc4_crtc.c +@@ -47,12 +47,17 @@ struct vc4_crtc { + const struct vc4_crtc_data *data; + void __iomem *regs; + ++ /* Timestamp at start of vblank irq - unaffected by lock delays. */ ++ ktime_t t_vblank; ++ + /* Which HVS channel we're using for our CRTC. */ + int channel; + + u8 lut_r[256]; + u8 lut_g[256]; + u8 lut_b[256]; ++ /* Size in pixels of the COB memory allocated to this CRTC. */ ++ u32 cob_size; + + struct drm_pending_vblank_event *event; + }; +@@ -134,6 +139,144 @@ int vc4_crtc_debugfs_regs(struct seq_fil + } + #endif + ++int vc4_crtc_get_scanoutpos(struct drm_device *dev, unsigned int crtc_id, ++ unsigned int flags, int *vpos, int *hpos, ++ ktime_t *stime, ktime_t *etime, ++ const struct drm_display_mode *mode) ++{ ++ struct vc4_dev *vc4 = to_vc4_dev(dev); ++ struct vc4_crtc *vc4_crtc = vc4->crtc[crtc_id]; ++ u32 val; ++ int fifo_lines; ++ int vblank_lines; ++ int ret = 0; ++ ++ /* ++ * XXX Doesn't work well in interlaced mode yet, partially due ++ * to problems in vc4 kms or drm core interlaced mode handling, ++ * so disable for now in interlaced mode. ++ */ ++ if (mode->flags & DRM_MODE_FLAG_INTERLACE) ++ return ret; ++ ++ /* preempt_disable_rt() should go right here in PREEMPT_RT patchset. */ ++ ++ /* Get optional system timestamp before query. */ ++ if (stime) ++ *stime = ktime_get(); ++ ++ /* ++ * Read vertical scanline which is currently composed for our ++ * pixelvalve by the HVS, and also the scaler status. ++ */ ++ val = HVS_READ(SCALER_DISPSTATX(vc4_crtc->channel)); ++ ++ /* Get optional system timestamp after query. */ ++ if (etime) ++ *etime = ktime_get(); ++ ++ /* preempt_enable_rt() should go right here in PREEMPT_RT patchset. */ ++ ++ /* Vertical position of hvs composed scanline. */ ++ *vpos = VC4_GET_FIELD(val, SCALER_DISPSTATX_LINE); ++ ++ /* No hpos info available. */ ++ if (hpos) ++ *hpos = 0; ++ ++ /* This is the offset we need for translating hvs -> pv scanout pos. */ ++ fifo_lines = vc4_crtc->cob_size / mode->crtc_hdisplay; ++ ++ if (fifo_lines > 0) ++ ret |= DRM_SCANOUTPOS_VALID; ++ ++ /* HVS more than fifo_lines into frame for compositing? */ ++ if (*vpos > fifo_lines) { ++ /* ++ * We are in active scanout and can get some meaningful results ++ * from HVS.

However the datasheet +specifies in section 12.1.3 that TXERIF will clear the TXRTS after a +transmit abort. Also in section 12.1.4 that TXIF will be set +when TXRTS transitions from '1' to '0'. Therefore the TXIF flag is enabled +during transmission errors. + +This causes a race condition, since the worker code will invoke +enc28j60_tx_clear() -> netif_wake_queue(), potentially invoking the +ndo_start_xmit function to send a new packet. The enc28j60_send_packet function +uses a workqueue that invokes enc28j60_hw_tx(). In between this function is +called, the worker from the interrupt handler will enter the path for error +handler because of the TXERIF flag, causing to invoke enc28j60_tx_clear() again +and releasing the packet scheduled for transmission, causing a kernel crash with +due a NULL pointer. + +These crashes due a NULL pointer were observed under stress conditions of the +device. A BUG_ON() sequence was used to validate the issue was fixed, and has +been running without problems for 2 years now. + +Signed-off-by: Diego Dompe <dompe@hpe.com> +Acked-by: Sergio Valverde <sergio.valverde@hpe.com> +Signed-off-by: David S.
