Additionally, new sample rates are difficult to +add to the table. Witness that the chip is capable of 192000 Hz +sampling, but it is not provided by this driver. Last, if the +driver is clocked by something that isn't a crystal, the +upstream clock may not be able to achieve exactly the rate +requested in the driver. This will mean that clocking will be +slightly off for the sampling clock or that it won't work at all. + +This patch determines the settings for all of the clocks at +runtime considering the real conditions of the clocks in the +system.

In such a case, +rewriting the code using non-atomic PCM ops will simplify the logic a +lot. + +This patch does it: all workqueue are gone and each former-work +implementation is now directly called from PCM ops like trigger and +write transfer. + +Along with it, the DMA position updater, bcm2835_playback_fifo(), was +also rewritten to use a simpler logic. Now it handles the XRUN and +draining properly by calling snd_pcm_stop() conditionally. + +The current position is kept in atomic_t value so that it can be read +concurrently from the pointer callback. + +Also, the bcm2835_audio_instance object is allocated at the beginning +of bcm2835_audio_open().

In order to perform +the I2C transfer, this driver sets the divider, which requires +it to get the parent clock rate, which it does with clk_get_rate(). +Unfortunately, this function will try to take the clock prepare +lock, which is already held by the slave's internal clock calls +creating a deadlock. + +Modeling the divider in the CCF natively removes this dependency +and the divider value is only set upon changing the bus clock +frequency or changes in the parent clock that cascade down to this +divisor. This obviates the need to set the divider with every +transfer and avoids the deadlock described above. It also should +provide better clock debugging and save a few cycles on each +transfer due to not having to recalcuate the divider value. + +Signed-off-by: Annaliese McDermond +Acked-by: Stefan Wahren +Reviewed-by: Eric Anholt +Signed-off-by: Wolfram Sang +--- + drivers/i2c/busses/i2c-bcm2835.c | 145 ++++++++++++++++++++++++------- + 1 file changed, 114 insertions(+), 31 deletions(-) + +--- a/drivers/i2c/busses/i2c-bcm2835.c ++++ b/drivers/i2c/busses/i2c-bcm2835.c +@@ -12,6 +12,8 @@ + */ + + #include ++#include ++#include + #include + #include + #include +@@ -71,9 +73,7 @@ struct bcm2835_debug { + struct bcm2835_i2c_dev { + struct device *dev; + void __iomem *regs; +- struct clk *clk; + int irq; +- u32 bus_clk_rate; + struct i2c_adapter adapter; + struct completion completion; + struct i2c_msg *curr_msg; +@@ -164,12 +164,17 @@ static inline u32 bcm2835_i2c_readl(stru + return readl(i2c_dev->regs + reg); + } + +-static int bcm2835_i2c_set_divider(struct bcm2835_i2c_dev *i2c_dev) ++#define to_clk_bcm2835_i2c(_hw) container_of(_hw, struct clk_bcm2835_i2c, hw) ++struct clk_bcm2835_i2c { ++ struct clk_hw hw; ++ struct bcm2835_i2c_dev *i2c_dev; ++}; ++ ++static int clk_bcm2835_i2c_calc_divider(unsigned long rate, ++ unsigned long parent_rate) + { +- u32 divider, redl, fedl; ++ u32 divider = DIV_ROUND_UP(parent_rate, rate); + +- divider = DIV_ROUND_UP(clk_get_rate(i2c_dev->clk), +- i2c_dev->bus_clk_rate); + /* + * Per the datasheet, the register is always interpreted as an even + * number, by rounding down.

In order to perform -the I2C transfer, this driver sets the divider, which requires -it to get the parent clock rate, which it does with clk_get_rate(). -Unfortunately, this function will try to take the clock prepare -lock, which is already held by the slave's internal clock calls -creating a deadlock. - -Modeling the divider in the CCF natively removes this dependency -and the divider value is only set upon changing the bus clock -frequency or changes in the parent clock that cascade down to this -divisor. This obviates the need to set the divider with every -transfer and avoids the deadlock described above. It also should -provide better clock debugging and save a few cycles on each -transfer due to not having to recalcuate the divider value. - -Signed-off-by: Annaliese McDermond -Acked-by: Stefan Wahren -Reviewed-by: Eric Anholt -Signed-off-by: Wolfram Sang ---- - drivers/i2c/busses/i2c-bcm2835.c | 145 ++++++++++++++++++++++++------- - 1 file changed, 114 insertions(+), 31 deletions(-) - ---- a/drivers/i2c/busses/i2c-bcm2835.c -+++ b/drivers/i2c/busses/i2c-bcm2835.c -@@ -12,6 +12,8 @@ - */ - - #include -+#include -+#include - #include - #include - #include -@@ -71,9 +73,7 @@ struct bcm2835_debug { - struct bcm2835_i2c_dev { - struct device *dev; - void __iomem *regs; -- struct clk *clk; - int irq; -- u32 bus_clk_rate; - struct i2c_adapter adapter; - struct completion completion; - struct i2c_msg *curr_msg; -@@ -164,12 +164,17 @@ static inline u32 bcm2835_i2c_readl(stru - return readl(i2c_dev->regs + reg); - } - --static int bcm2835_i2c_set_divider(struct bcm2835_i2c_dev *i2c_dev) -+#define to_clk_bcm2835_i2c(_hw) container_of(_hw, struct clk_bcm2835_i2c, hw) -+struct clk_bcm2835_i2c { -+ struct clk_hw hw; -+ struct bcm2835_i2c_dev *i2c_dev; -+}; -+ -+static int clk_bcm2835_i2c_calc_divider(unsigned long rate, -+ unsigned long parent_rate) - { -- u32 divider, redl, fedl; -+ u32 divider = DIV_ROUND_UP(parent_rate, rate); - -- divider = DIV_ROUND_UP(clk_get_rate(i2c_dev->clk), -- i2c_dev->bus_clk_rate); - /* - * Per the datasheet, the register is always interpreted as an even - * number, by rounding down.

This close relationship adds complexity to how cpu +system memory is mapped to PCIe memory. Ideally, this mapping is an +identity mapping, or an identity mapping off by a constant. Not so in +this case. + +Consider the Broadcom reference board BCM97445LCC_4X8 which has 6 GB +of system memory. Here is how the PCIe controller maps the +system memory to PCIe memory: + + memc0-a@[ 0....3fffffff] <=> pci@[ 0....3fffffff] + memc0-b@[100000000...13fffffff] <=> pci@[ 40000000....7fffffff] + memc1-a@[ 40000000....7fffffff] <=> pci@[ 80000000....bfffffff] + memc1-b@[300000000...33fffffff] <=> pci@[ c0000000....ffffffff] + memc2-a@[ 80000000....bfffffff] <=> pci@[100000000...13fffffff] + memc2-b@[c00000000...c3fffffff] <=> pci@[140000000...17fffffff] + +Although there are some "gaps" that can be added between the +individual mappings by software, the permutation of memory regions for +the most part is fixed by HW. The solution of having something close +to an identity mapping is not possible. + +The idea behind this HW design is that the same PCIe module can +act as an RC or EP, and if it acts as an EP it concatenates all +of system memory into a BAR so anything can be accessed. Unfortunately, +when the PCIe block is in the role of an RC it also presents this +"BAR" to downstream PCIe devices, rather than offering an identity map +between its system memory and PCIe space. + +Suppose that an endpoint driver allocs some DMA memory. Suppose this +memory is located at 0x6000_0000, which is in the middle of memc1-a. +The driver wants a dma_addr_t value that it can pass on to the EP to +use. Without doing any custom mapping, the EP will use this value for +DMA: the driver will get a dma_addr_t equal to 0x6000_0000. But this +won't work; the device needs a dma_addr_t that reflects the PCIe space +address, namely 0xa000_0000. + +So, essentially the solution to this problem must modify the +dma_addr_t returned by the DMA routines routines. There are two +ways (I know of) of doing this: + +(a) overriding/redefining the dma_to_phys() and phys_to_dma() calls +that are used by the dma_ops routines. This is the approach of + + arch/mips/cavium-octeon/dma-octeon.c + +In ARM and ARM64 these two routines are defiend in asm/dma-mapping.h +as static inline functions. + +(b) Subscribe to a notifier that notifies when a device is added to a +bus. When this happens, set_dma_ops() can be called for the device. +This method is mentioned in: + + http://lxr.free-electrons.com/source/drivers/of/platform.c?v=3.16#L152 + +where it says as a comment + + "In case if platform code need to use own special DMA + configuration, it can use Platform bus notifier and + handle BUS_NOTIFY_ADD_DEVICE event to fix up DMA + configuration." + +Solution (b) is what this commit does. It uses its own set of +dma_ops which are wrappers around the arch_dma_ops. The +wrappers translate the dma addresses before/after invoking +the arch_dma_ops, as appropriate. + +Signed-off-by: Jim Quinlan +--- + drivers/pci/controller/pcie-brcmstb.c | 420 +++++++++++++++++++++++++- + 1 file changed, 411 insertions(+), 9 deletions(-) + +--- a/drivers/pci/controller/pcie-brcmstb.c ++++ b/drivers/pci/controller/pcie-brcmstb.c +@@ -4,6 +4,7 @@ + #include + #include + #include ++#include + #include + #include + #include +@@ -319,11 +320,307 @@ static struct pci_ops brcm_pcie_ops = { + ((val & ~reg##_##field##_MASK) | \ + (reg##_##field##_MASK & (field_val << reg##_##field##_SHIFT))) + ++static const struct dma_map_ops *arch_dma_ops;

This close relationship adds complexity to how cpu -system memory is mapped to PCIe memory. Ideally, this mapping is an -identity mapping, or an identity mapping off by a constant. Not so in -this case. - -Consider the Broadcom reference board BCM97445LCC_4X8 which has 6 GB -of system memory. Here is how the PCIe controller maps the -system memory to PCIe memory: - - memc0-a@[ 0....3fffffff] <=> pci@[ 0....3fffffff] - memc0-b@[100000000...13fffffff] <=> pci@[ 40000000....7fffffff] - memc1-a@[ 40000000....7fffffff] <=> pci@[ 80000000....bfffffff] - memc1-b@[300000000...33fffffff] <=> pci@[ c0000000....ffffffff] - memc2-a@[ 80000000....bfffffff] <=> pci@[100000000...13fffffff] - memc2-b@[c00000000...c3fffffff] <=> pci@[140000000...17fffffff] - -Although there are some "gaps" that can be added between the -individual mappings by software, the permutation of memory regions for -the most part is fixed by HW. The solution of having something close -to an identity mapping is not possible. - -The idea behind this HW design is that the same PCIe module can -act as an RC or EP, and if it acts as an EP it concatenates all -of system memory into a BAR so anything can be accessed. Unfortunately, -when the PCIe block is in the role of an RC it also presents this -"BAR" to downstream PCIe devices, rather than offering an identity map -between its system memory and PCIe space. - -Suppose that an endpoint driver allocs some DMA memory. Suppose this -memory is located at 0x6000_0000, which is in the middle of memc1-a. -The driver wants a dma_addr_t value that it can pass on to the EP to -use. Without doing any custom mapping, the EP will use this value for -DMA: the driver will get a dma_addr_t equal to 0x6000_0000. But this -won't work; the device needs a dma_addr_t that reflects the PCIe space -address, namely 0xa000_0000. - -So, essentially the solution to this problem must modify the -dma_addr_t returned by the DMA routines routines. There are two -ways (I know of) of doing this: - -(a) overriding/redefining the dma_to_phys() and phys_to_dma() calls -that are used by the dma_ops routines. This is the approach of - - arch/mips/cavium-octeon/dma-octeon.c - -In ARM and ARM64 these two routines are defiend in asm/dma-mapping.h -as static inline functions. - -(b) Subscribe to a notifier that notifies when a device is added to a -bus. When this happens, set_dma_ops() can be called for the device. -This method is mentioned in: - - http://lxr.free-electrons.com/source/drivers/of/platform.c?v=3.16#L152 - -where it says as a comment - - "In case if platform code need to use own special DMA - configuration, it can use Platform bus notifier and - handle BUS_NOTIFY_ADD_DEVICE event to fix up DMA - configuration." - -Solution (b) is what this commit does. It uses its own set of -dma_ops which are wrappers around the arch_dma_ops. The -wrappers translate the dma addresses before/after invoking -the arch_dma_ops, as appropriate. - -Signed-off-by: Jim Quinlan ---- - drivers/pci/controller/pcie-brcmstb.c | 420 +++++++++++++++++++++++++- - 1 file changed, 411 insertions(+), 9 deletions(-) - ---- a/drivers/pci/controller/pcie-brcmstb.c -+++ b/drivers/pci/controller/pcie-brcmstb.c -@@ -4,6 +4,7 @@ - #include - #include - #include -+#include - #include - #include - #include -@@ -319,11 +320,307 @@ static struct pci_ops brcm_pcie_ops = { - ((val & ~reg##_##field##_MASK) | \ - (reg##_##field##_MASK & (field_val << reg##_##field##_SHIFT))) - -+static const struct dma_map_ops *arch_dma_ops;

This will certainly be +useful for media EGL image input, but is also useful immediately for +mipmap generation without bogging the V3D core down. + +For now we only run the queue 1 job deep, and don't have any hang +recovery (though I don't think we should need it, with TFU). Queuing +multiple jobs in the HW will require synchronizing the YUV coefficient +regs updates since they don't get FIFOed with the job. + +v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain + why TFU is AUTH, clarify the syncing docs, drop the unused TFU + interrupt regs (you're expected to use the hub's), don't take + &bo->base for NULL bos. +v3: Fix a little whitespace alignment (noticed by checkpatch), rebase + on drm_sched_job_cleanup() changes. + +Signed-off-by: Eric Anholt +Reviewed-by: Dave Emett (v2) +Link: https://patchwork.freedesktop.org/patch/264607/ +(cherry picked from commit 1584f16ca96ef124aad79efa3303cff5f3530e2c) +--- + drivers/gpu/drm/v3d/v3d_drv.c | 15 ++- + drivers/gpu/drm/v3d/v3d_drv.h | 32 +++++- + drivers/gpu/drm/v3d/v3d_gem.c | 178 ++++++++++++++++++++++++++++---- + drivers/gpu/drm/v3d/v3d_irq.c | 12 ++- + drivers/gpu/drm/v3d/v3d_regs.h | 49 +++++++++ + drivers/gpu/drm/v3d/v3d_sched.c | 148 ++++++++++++++++++++++---- + drivers/gpu/drm/v3d/v3d_trace.h | 20 ++++ + include/uapi/drm/v3d_drm.h | 25 +++++ + 8 files changed, 426 insertions(+), 53 deletions(-) + +--- a/drivers/gpu/drm/v3d/v3d_drv.c ++++ b/drivers/gpu/drm/v3d/v3d_drv.c +@@ -112,10 +112,15 @@ static int v3d_get_param_ioctl(struct dr + return 0; + } + +- /* Any params that aren't just register reads would go here. */ + +- DRM_DEBUG("Unknown parameter %d\n", args->param); +- return -EINVAL; ++ switch (args->param) { ++ case DRM_V3D_PARAM_SUPPORTS_TFU: ++ args->value = 1; ++ return 0; ++ default: ++ DRM_DEBUG("Unknown parameter %d\n", args->param); ++ return -EINVAL; ++ } + } + + static int +@@ -170,7 +175,8 @@ static const struct file_operations v3d_ + /* DRM_AUTH is required on SUBMIT_CL for now, while we don't have GMP + * protection between clients.

Queuing -multiple jobs in the HW will require synchronizing the YUV coefficient -regs updates since they don't get FIFOed with the job. - -v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain - why TFU is AUTH, clarify the syncing docs, drop the unused TFU - interrupt regs (you're expected to use the hub's), don't take - &bo->base for NULL bos. -v3: Fix a little whitespace alignment (noticed by checkpatch), rebase - on drm_sched_job_cleanup() changes. - -Signed-off-by: Eric Anholt -Reviewed-by: Dave Emett (v2) -Link: https://patchwork.freedesktop.org/patch/264607/ -(cherry picked from commit 1584f16ca96ef124aad79efa3303cff5f3530e2c) ---- - drivers/gpu/drm/v3d/v3d_drv.c | 15 ++- - drivers/gpu/drm/v3d/v3d_drv.h | 32 +++++- - drivers/gpu/drm/v3d/v3d_gem.c | 178 ++++++++++++++++++++++++++++---- - drivers/gpu/drm/v3d/v3d_irq.c | 12 ++- - drivers/gpu/drm/v3d/v3d_regs.h | 49 +++++++++ - drivers/gpu/drm/v3d/v3d_sched.c | 148 ++++++++++++++++++++++---- - drivers/gpu/drm/v3d/v3d_trace.h | 20 ++++ - include/uapi/drm/v3d_drm.h | 25 +++++ - 8 files changed, 426 insertions(+), 53 deletions(-) - ---- a/drivers/gpu/drm/v3d/v3d_drv.c -+++ b/drivers/gpu/drm/v3d/v3d_drv.c -@@ -112,10 +112,15 @@ static int v3d_get_param_ioctl(struct dr - return 0; - } - -- /* Any params that aren't just register reads would go here. */ - -- DRM_DEBUG("Unknown parameter %d\n", args->param); -- return -EINVAL; -+ switch (args->param) { -+ case DRM_V3D_PARAM_SUPPORTS_TFU: -+ args->value = 1; -+ return 0; -+ default: -+ DRM_DEBUG("Unknown parameter %d\n", args->param); -+ return -EINVAL; -+ } - } - - static int -@@ -170,7 +175,8 @@ static const struct file_operations v3d_ - /* DRM_AUTH is required on SUBMIT_CL for now, while we don't have GMP - * protection between clients.

This is different behavior than for other memory +types and prevents us from deallocating buffers in following two cases: + +1) There are outstanding mmap()ed views on the buffer. However even if + we put the buffer in reqbufs(0), there will be remaining references, + due to vma .open/close() adjusting vb2 buffer refcount appropriately. + This means that the buffer will be in fact freed only when the last + mmap()ed view is unmapped. + +2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer + is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF + get and decremented on DMABUF release. This means that the buffer + will be alive until all importers release it. + +Considering both cases above, there does not seem to be any need to +prevent reqbufs(0) operation, because buffer lifetime is already +properly managed by both mmap() and DMABUF code paths. Let's remove it +and allow userspace freeing the queue (and potentially allocating a new +one) even though old buffers might be still in processing. + +To let userspace know that the kernel now supports orphaning buffers +that are still in use, add a new V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS +to be set by reqbufs and create_bufs. + +[p.zabel@pengutronix.de: added V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS, + updated documentation, and added back debug message] + +Signed-off-by: John Sheu +Reviewed-by: Pawel Osciak +Signed-off-by: Tomasz Figa +Signed-off-by: Philipp Zabel +Acked-by: Sakari Ailus +Signed-off-by: Hans Verkuil +[hverkuil-cisco@xs4all.nl: added V4L2-BUF-CAP-SUPPORTS-ORPHANED-BUFS ref] +Signed-off-by: Mauro Carvalho Chehab +--- + Documentation/media/uapi/v4l/vidioc-reqbufs.rst | 17 ++++++++++++++--- + drivers/media/common/videobuf2/videobuf2-core.c | 8 +++----- + drivers/media/common/videobuf2/videobuf2-v4l2.c | 2 +- + include/uapi/linux/videodev2.h | 1 + + 4 files changed, 19 insertions(+), 9 deletions(-) + +--- a/Documentation/media/uapi/v4l/vidioc-reqbufs.rst ++++ b/Documentation/media/uapi/v4l/vidioc-reqbufs.rst +@@ -59,9 +59,14 @@ When the I/O method is not supported the + code. + + Applications can call :ref:`VIDIOC_REQBUFS` again to change the number of +-buffers, however this cannot succeed when any buffers are still mapped. +-A ``count`` value of zero frees all buffers, after aborting or finishing +-any DMA in progress, an implicit ++buffers.

This is different behavior than for other memory -types and prevents us from deallocating buffers in following two cases: - -1) There are outstanding mmap()ed views on the buffer. However even if - we put the buffer in reqbufs(0), there will be remaining references, - due to vma .open/close() adjusting vb2 buffer refcount appropriately. - This means that the buffer will be in fact freed only when the last - mmap()ed view is unmapped. - -2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer - is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF - get and decremented on DMABUF release. This means that the buffer - will be alive until all importers release it. - -Considering both cases above, there does not seem to be any need to -prevent reqbufs(0) operation, because buffer lifetime is already -properly managed by both mmap() and DMABUF code paths. Let's remove it -and allow userspace freeing the queue (and potentially allocating a new -one) even though old buffers might be still in processing. - -To let userspace know that the kernel now supports orphaning buffers -that are still in use, add a new V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS -to be set by reqbufs and create_bufs. - -[p.zabel@pengutronix.de: added V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS, - updated documentation, and added back debug message] - -Signed-off-by: John Sheu -Reviewed-by: Pawel Osciak -Signed-off-by: Tomasz Figa -Signed-off-by: Philipp Zabel -Acked-by: Sakari Ailus -Signed-off-by: Hans Verkuil -[hverkuil-cisco@xs4all.nl: added V4L2-BUF-CAP-SUPPORTS-ORPHANED-BUFS ref] -Signed-off-by: Mauro Carvalho Chehab ---- - Documentation/media/uapi/v4l/vidioc-reqbufs.rst | 17 ++++++++++++++--- - drivers/media/common/videobuf2/videobuf2-core.c | 8 +++----- - drivers/media/common/videobuf2/videobuf2-v4l2.c | 2 +- - include/uapi/linux/videodev2.h | 1 + - 4 files changed, 19 insertions(+), 9 deletions(-) - ---- a/Documentation/media/uapi/v4l/vidioc-reqbufs.rst -+++ b/Documentation/media/uapi/v4l/vidioc-reqbufs.rst -@@ -59,9 +59,14 @@ When the I/O method is not supported the - code. - - Applications can call :ref:`VIDIOC_REQBUFS` again to change the number of --buffers, however this cannot succeed when any buffers are still mapped. --A ``count`` value of zero frees all buffers, after aborting or finishing --any DMA in progress, an implicit -+buffers.
