It should contain one 'port' child node ++with child 'endpoint' node.

When from_irq is true the function assumes that the +FIFO is half empty and writes up to half a FIFO's worth of bytes +without polling the FIFO status register, the reasoning being that +the function is being called as a result of the TX interrupt being +raised. This logic would work were it not for the fact that +pl011_rx_chars, called from pl011_int before pl011_tx_chars, releases +the spinlock before calling tty_flip_buffer_push. + +A user thread writing to the UART claims the spinlock and ultimately +calls pl011_tx_chars with from_irq set to false. This reverts to the +older logic that polls the FIFO status register before sending every +byte. If this happen on an SMP system during the section of the IRQ +handler where the spinlock has been released, then by the time the TX +interrupt handler is called, the FIFO may already be full, and any +further writes are likely to be lost. + +The fix involves adding a per-port flag that is true iff running from +within the interrupt handler and the spinlock has not yet been released. +This flag is then used as the value for the from_irq parameter of +pl011_tx_chars, causing polling to be used in the unsafe case. + +Fixes: 1e84d22322ce ("serial/amba-pl011: Refactor and simplify TX FIFO handling") + +Signed-off-by: Phil Elwell +--- + drivers/tty/serial/amba-pl011.c | 7 ++++++- + 1 file changed, 6 insertions(+), 1 deletion(-) + +--- a/drivers/tty/serial/amba-pl011.c ++++ b/drivers/tty/serial/amba-pl011.c +@@ -270,6 +270,7 @@ struct uart_amba_port { + unsigned int old_cr; /* state during shutdown */ + unsigned int fixed_baud; /* vendor-set fixed baud rate */ + char type[12]; ++ bool irq_locked; /* in irq, unreleased lock */ + #ifdef CONFIG_DMA_ENGINE + /* DMA stuff */ + bool using_tx_dma; +@@ -816,6 +817,7 @@ __acquires(&uap->port.lock) + if (!uap->using_tx_dma) + return; + ++ uap->irq_locked = 0; + dmaengine_terminate_async(uap->dmatx.chan); + + if (uap->dmatx.queued) { +@@ -942,6 +944,7 @@ static void pl011_dma_rx_chars(struct ua + fifotaken = pl011_fifo_to_tty(uap); + } + ++ uap->irq_locked = 0; + spin_unlock(&uap->port.lock); + dev_vdbg(uap->port.dev, + "Took %d chars from DMA buffer and %d chars from the FIFO\n", +@@ -1350,6 +1353,7 @@ __acquires(&uap->port.lock) + { + pl011_fifo_to_tty(uap); + ++ uap->irq_locked = 0; + spin_unlock(&uap->port.lock); + tty_flip_buffer_push(&uap->port.state->port); + /* +@@ -1485,6 +1489,7 @@ static irqreturn_t pl011_int(int irq, vo + int handled = 0; + + spin_lock_irqsave(&uap->port.lock, flags); ++ uap->irq_locked = 1; + status = pl011_read(uap, REG_RIS) & uap->im; + if (status) { + do { +@@ -1504,7 +1509,7 @@ static irqreturn_t pl011_int(int irq, vo + UART011_CTSMIS|UART011_RIMIS)) + pl011_modem_status(uap); + if (status & UART011_TXIS) +- pl011_tx_chars(uap, true); ++ pl011_tx_chars(uap, uap->irq_locked); + + if (pass_counter-- == 0) + break; diff --git a/target/linux/bcm27xx/patches-5.4/950-0264-drm-vc4_dsi-Fix-DMA-channel-and-memory-leak-in-vc4-3.patch b/target/linux/bcm27xx/patches-5.4/950-0264-drm-vc4_dsi-Fix-DMA-channel-and-memory-leak-in-vc4-3.patch deleted file mode 100644 index 9fd796850f..0000000000 --- a/target/linux/bcm27xx/patches-5.4/950-0264-drm-vc4_dsi-Fix-DMA-channel-and-memory-leak-in-vc4-3.patch +++ /dev/null @@ -1,135 +0,0 @@ -From cbda8e6de54f8a0f194e990f53e1cfad642af1be Mon Sep 17 00:00:00 2001 -From: Chris Miller -Date: Wed, 26 Jun 2019 10:40:30 +0100 -Subject: [PATCH] drm: vc4_dsi: Fix DMA channel and memory leak in vc4 - (#3012) - -Signed-off-by: Chris G Miller ---- - drivers/gpu/drm/vc4/vc4_dsi.c | 35 ++++++++++++++++++++++++----------- - 1 file changed, 24 insertions(+), 11 deletions(-) - ---- a/drivers/gpu/drm/vc4/vc4_dsi.c -+++ b/drivers/gpu/drm/vc4/vc4_dsi.c -@@ -1485,9 +1485,11 @@ static int vc4_dsi_bind(struct device *d - /* DSI1 has a broken AXI slave that doesn't respond to writes - * from the ARM.

When from_irq is true the function assumes that the -FIFO is half empty and writes up to half a FIFO's worth of bytes -without polling the FIFO status register, the reasoning being that -the function is being called as a result of the TX interrupt being -raised. This logic would work were it not for the fact that -pl011_rx_chars, called from pl011_int before pl011_tx_chars, releases -the spinlock before calling tty_flip_buffer_push. - -A user thread writing to the UART claims the spinlock and ultimately -calls pl011_tx_chars with from_irq set to false. This reverts to the -older logic that polls the FIFO status register before sending every -byte. If this happen on an SMP system during the section of the IRQ -handler where the spinlock has been released, then by the time the TX -interrupt handler is called, the FIFO may already be full, and any -further writes are likely to be lost. - -The fix involves adding a per-port flag that is true iff running from -within the interrupt handler and the spinlock has not yet been released. -This flag is then used as the value for the from_irq parameter of -pl011_tx_chars, causing polling to be used in the unsafe case. - -Fixes: 1e84d22322ce ("serial/amba-pl011: Refactor and simplify TX FIFO handling") - -Signed-off-by: Phil Elwell ---- - drivers/tty/serial/amba-pl011.c | 7 ++++++- - 1 file changed, 6 insertions(+), 1 deletion(-) - ---- a/drivers/tty/serial/amba-pl011.c -+++ b/drivers/tty/serial/amba-pl011.c -@@ -270,6 +270,7 @@ struct uart_amba_port { - unsigned int old_cr; /* state during shutdown */ - unsigned int fixed_baud; /* vendor-set fixed baud rate */ - char type[12]; -+ bool irq_locked; /* in irq, unreleased lock */ - #ifdef CONFIG_DMA_ENGINE - /* DMA stuff */ - bool using_tx_dma; -@@ -816,6 +817,7 @@ __acquires(&uap->port.lock) - if (!uap->using_tx_dma) - return; - -+ uap->irq_locked = 0; - dmaengine_terminate_async(uap->dmatx.chan); - - if (uap->dmatx.queued) { -@@ -942,6 +944,7 @@ static void pl011_dma_rx_chars(struct ua - fifotaken = pl011_fifo_to_tty(uap); - } - -+ uap->irq_locked = 0; - spin_unlock(&uap->port.lock); - dev_vdbg(uap->port.dev, - "Took %d chars from DMA buffer and %d chars from the FIFO\n", -@@ -1350,6 +1353,7 @@ __acquires(&uap->port.lock) - { - pl011_fifo_to_tty(uap); - -+ uap->irq_locked = 0; - spin_unlock(&uap->port.lock); - tty_flip_buffer_push(&uap->port.state->port); - /* -@@ -1485,6 +1489,7 @@ static irqreturn_t pl011_int(int irq, vo - int handled = 0; - - spin_lock_irqsave(&uap->port.lock, flags); -+ uap->irq_locked = 1; - status = pl011_read(uap, REG_RIS) & uap->im; - if (status) { - do { -@@ -1504,7 +1509,7 @@ static irqreturn_t pl011_int(int irq, vo - UART011_CTSMIS|UART011_RIMIS)) - pl011_modem_status(uap); - if (status & UART011_TXIS) -- pl011_tx_chars(uap, true); -+ pl011_tx_chars(uap, uap->irq_locked); - - if (pass_counter-- == 0) - break; diff --git a/target/linux/bcm27xx/patches-5.4/950-0267-clk-bcm2835-Avoid-null-pointer-exception.patch b/target/linux/bcm27xx/patches-5.4/950-0267-clk-bcm2835-Avoid-null-pointer-exception.patch new file mode 100644 index 0000000000..8a529af7b0 --- /dev/null +++ b/target/linux/bcm27xx/patches-5.4/950-0267-clk-bcm2835-Avoid-null-pointer-exception.patch @@ -0,0 +1,29 @@ +From 7316a9e5720c2f4112a96b32c4ec78d94a44adcf Mon Sep 17 00:00:00 2001 +From: popcornmix +Date: Tue, 6 Aug 2019 15:23:14 +0100 +Subject: [PATCH] clk-bcm2835: Avoid null pointer exception + +clk_desc_array[BCM2835_PLLB] doesn't exist so we dereference null when iterating + +Signed-off-by: popcornmix +--- + drivers/clk/bcm/clk-bcm2835.c | 8 +++++--- + 1 file changed, 5 insertions(+), 3 deletions(-) + +--- a/drivers/clk/bcm/clk-bcm2835.c ++++ b/drivers/clk/bcm/clk-bcm2835.c +@@ -2280,9 +2280,11 @@ static bool bcm2835_clk_is_claimed(const + int i; + + for (i = 0; i < ARRAY_SIZE(clk_desc_array); i++) { +- const char *clk_name = *(const char **)(clk_desc_array[i].data); +- if (!strcmp(name, clk_name)) +- return bcm2835_clk_claimed[i]; ++ if (clk_desc_array[i].data) { ++ const char *clk_name = *(const char **)(clk_desc_array[i].data); ++ if (!strcmp(name, clk_name)) ++ return bcm2835_clk_claimed[i]; ++ } + } + + return false; diff --git a/target/linux/bcm27xx/patches-5.4/950-0267-xhci-add-quirk-for-host-controllers-that-don-t-updat.patch b/target/linux/bcm27xx/patches-5.4/950-0267-xhci-add-quirk-for-host-controllers-that-don-t-updat.patch deleted file mode 100644 index a125fdcb47..0000000000 --- a/target/linux/bcm27xx/patches-5.4/950-0267-xhci-add-quirk-for-host-controllers-that-don-t-updat.patch +++ /dev/null @@ -1,90 +0,0 @@ -From 7bb9b7d36fa457a9fc463108d1228fd318891da4 Mon Sep 17 00:00:00 2001 -From: Jonathan Bell -Date: Thu, 11 Jul 2019 17:55:43 +0100 -Subject: [PATCH] xhci: add quirk for host controllers that don't - update endpoint DCS - -Seen on a VLI VL805 PCIe to USB controller.

Until that is done, simply return a value -of 1. - -Signed-off-by: Chen-Yu Tsai ---- - .../vc04_services/bcm2835-codec/bcm2835-v4l2-codec.c | 12 ++++++++++++ - 1 file changed, 12 insertions(+) - ---- a/drivers/staging/vc04_services/bcm2835-codec/bcm2835-v4l2-codec.c -+++ b/drivers/staging/vc04_services/bcm2835-codec/bcm2835-v4l2-codec.c -@@ -2357,6 +2357,18 @@ static int bcm2835_codec_open(struct fil - } - ctx->fh.ctrl_handler = hdl; - v4l2_ctrl_handler_setup(hdl); -+ } else if (dev->role == DECODE) { -+ v4l2_ctrl_handler_init(hdl, 1); -+ -+ v4l2_ctrl_new_std(hdl, &bcm2835_codec_ctrl_ops, -+ V4L2_CID_MIN_BUFFERS_FOR_CAPTURE, -+ 1, 1, 1, 1); -+ if (hdl->error) { -+ rc = hdl->error; -+ goto free_ctrl_handler; -+ } -+ ctx->fh.ctrl_handler = hdl; -+ v4l2_ctrl_handler_setup(hdl); - } - - ctx->fh.m2m_ctx = v4l2_m2m_ctx_init(dev->m2m_dev, ctx, &queue_init); diff --git a/target/linux/bcm27xx/patches-5.4/950-0288-drm-vc4-Remove-unused-mode-variable.patch b/target/linux/bcm27xx/patches-5.4/950-0288-drm-vc4-Remove-unused-mode-variable.patch new file mode 100644 index 0000000000..e82fc421d2 --- /dev/null +++ b/target/linux/bcm27xx/patches-5.4/950-0288-drm-vc4-Remove-unused-mode-variable.patch @@ -0,0 +1,27 @@ +From 71402ae2a97b18f0c03b763a2e1e2800f360d50a Mon Sep 17 00:00:00 2001 +From: Dave Stevenson +Date: Thu, 25 Jul 2019 17:34:29 +0100 +Subject: [PATCH] drm/vc4: Remove unused mode variable + +"89d1376 drm/vc4: Add support for margins to fkms" removed +the requirement for having the mode structure from vc4_plane_to_mb, +but didn't remove it as a local to the function, causing a +compiler warning. + +Remove the unused variable. + +Signed-off-by: Dave Stevenson +--- + drivers/gpu/drm/vc4/vc4_firmware_kms.c | 1 - + 1 file changed, 1 deletion(-) + +--- a/drivers/gpu/drm/vc4/vc4_firmware_kms.c ++++ b/drivers/gpu/drm/vc4/vc4_firmware_kms.c +@@ -525,7 +525,6 @@ static int vc4_plane_to_mb(struct drm_pl + const struct vc_image_format *vc_fmt = + vc4_get_vc_image_fmt(drm_fmt->format); + int num_planes = fb->format->num_planes; +- struct drm_display_mode *mode = &state->crtc->mode; + unsigned int rotation = SUPPORTED_ROTATIONS; + + mb->plane.vc_image_type = vc_fmt->vc_image; diff --git a/target/linux/bcm27xx/patches-5.4/950-0288-staging-bcm2835-codec-set-device_caps-in-struct-vide.patch b/target/linux/bcm27xx/patches-5.4/950-0288-staging-bcm2835-codec-set-device_caps-in-struct-vide.patch deleted file mode 100644 index a194eaba14..0000000000 --- a/target/linux/bcm27xx/patches-5.4/950-0288-staging-bcm2835-codec-set-device_caps-in-struct-vide.patch +++ /dev/null @@ -1,40 +0,0 @@ -From d06677b96fc10122363028dea9ca06e5f9899865 Mon Sep 17 00:00:00 2001 -From: Chen-Yu Tsai -Date: Mon, 22 Jul 2019 22:20:55 +0800 -Subject: [PATCH] staging: bcm2835-codec: set device_caps in struct - video_device - -Instead of filling in the struct v4l2_capability device_caps -field, fill in the struct video_device device_caps field. - -That way the V4L2 core knows what the capabilities of the -video device are. - -This is similar to a cleanup series by Hans Verkuil [1]. - -[1] https://www.spinics.net/lists/linux-media/msg153313.html - -Signed-off-by: Chen-Yu Tsai ---- - .../staging/vc04_services/bcm2835-codec/bcm2835-v4l2-codec.c | 3 +-- - 1 file changed, 1 insertion(+), 2 deletions(-) - ---- a/drivers/staging/vc04_services/bcm2835-codec/bcm2835-v4l2-codec.c -+++ b/drivers/staging/vc04_services/bcm2835-codec/bcm2835-v4l2-codec.c -@@ -945,8 +945,6 @@ static int vidioc_querycap(struct file * - strncpy(cap->card, MEM2MEM_NAME, sizeof(cap->card) - 1); - snprintf(cap->bus_info, sizeof(cap->bus_info), "platform:%s", - MEM2MEM_NAME); -- cap->device_caps = V4L2_CAP_VIDEO_M2M_MPLANE | V4L2_CAP_STREAMING; -- cap->capabilities = cap->device_caps | V4L2_CAP_DEVICE_CAPS; - return 0; - } - -@@ -2600,6 +2598,7 @@ static int bcm2835_codec_create(struct p - vfd = &dev->vfd; - vfd->lock = &dev->dev_mutex; - vfd->v4l2_dev = &dev->v4l2_dev; -+ vfd->device_caps = V4L2_CAP_VIDEO_M2M_MPLANE | V4L2_CAP_STREAMING; - - switch (role) { - case DECODE: diff --git a/target/linux/bcm27xx/patches-5.4/950-0289-Add-HDMI1-facility-to-the-driver.patch b/target/linux/bcm27xx/patches-5.4/950-0289-Add-HDMI1-facility-to-the-driver.patch deleted file mode 100644 index b18d1458fd..0000000000 --- a/target/linux/bcm27xx/patches-5.4/950-0289-Add-HDMI1-facility-to-the-driver.patch +++ /dev/null @@ -1,85 +0,0 @@ -From fb8e73c19c2e153444b34e8d9804371095e92fe0 Mon Sep 17 00:00:00 2001 -From: James Hughes -Date: Tue, 16 Jul 2019 12:18:21 +0100 -Subject: [PATCH] Add HDMI1 facility to the driver. - -For generic ALSA, all you need is the bcm2835.h change, but -have also added structures for IEC958 HDMI.

The possible values go from 16MB +to 944MB, with a default of 64MB. This memory resides in the topmost +part of the lower 1GB memory area and grows bigger expanding towards the +begging of memory. + +It turns out that with low 'gpu_mem' values (16MB and 32MB) the size of +the memory available to the system in the lower 1GB area can outgrow the +interconnect's dma-range as its size was selected based on the maximum +system memory available given the default gpu_mem configuration. This +makes that memory slice unavailable for DMA. And may cause nasty kernel +warnings if CMA happens to include it. + +Change soc's dma-ranges to really reflect it's HW limitation, which is +being able to only DMA to the lower 1GB area. + +Fixes: 7dbe8c62ceeb ("ARM: dts: Add minimal Raspberry Pi 4 support") +Signed-off-by: Nicolas Saenz Julienne +Reviewed-by: Phil Elwell +Signed-off-by: Florian Fainelli +--- + arch/arm/boot/dts/bcm2711.dtsi | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +--- a/arch/arm/boot/dts/bcm2711.dtsi ++++ b/arch/arm/boot/dts/bcm2711.dtsi +@@ -43,7 +43,7 @@ + <0x7c000000 0x0 0xfc000000 0x02000000>, + <0x40000000 0x0 0xff800000 0x00800000>;
