vchi has a set of transfer flags which almost map 1:1 to vchiq's own transfer modes. For the sake of simplicity let's use the later and delete vchi's. Signed-off-by:

vchi_msg_dequeue() provides the same functionality as vchi_msg_hold() except it copies the message data as opposed to the later which provides the data in place. The copying is done on a local variable, so there is no need to keep the message out the function's bounds, so use vchi_msg_hold() instead. Signed-off-by:

The idea behind struct vchi_service_handle is to create an opaque handle to struct shim_service. This can be achieved by doing a forward declaration of struct shim_service, which will avoid unwarranted casts and pointer play. Ultimately as a rename is due all over the vchi user space, rename struct shim_service into struvt vchi_service, which is more consistent with the rest of the exposed API. Signed-off-by:

The idea behind this was to create an opaque handle to struct vchiq_instance. This can be achieved without creating a new type by means of a forward declaration of struct vchiq_instance. This saves us from a lot of useless casting and overall simplifies code. Signed-off-by:

There already is a function that covers most of the functionality vchi_msg_peek() provides: vchi_msg_hold(). The main difference being that the later removes the message from vchu's queue while the other does it later on, while releasing the message. There are no users of this function that can't be trivially converted to vchi_msg_hold(). So, for the sake of removing duplicate code, get rid of vchi_msg_peek(). Note that the opposite change could be performed as well. But vchi_msg_peek()'s implementation was deemed less robust as messages have to be released in order. Signed-off-by:

There is an enum for the errors that the VPU can return. port_parameter_get was negating that value, but also using -EINVAL from the Linux error codes. Pass the VPU error code as positive values. Should the function need to pass a Linux failure, then return that as negative. Signed-off-by:

mmal-vchiq is a reimplementation of the userland library for MMAL. When getting a parameter, the client provides the storage and the size of the storage. The VPU then returns the size of the parameter that it wished to return, and as much as possible of that parameter is returned to the client. The implementation previously only returned the size provided by the VPU should it exceed the buffer size. So for parameters such as the supported encodings list the client had no idea how much of the provided storage had been populated. Signed-off-by:

The MMAL client_component field is used with the event mechanism to allow the client to identify the component for which the event is generated. The field is only 32bits in size, therefore we can't use a pointer to the component in a 64 bit kernel. Component handles are already held in an array per VCHI instance, so use the array index as the client_component handle to avoid having to create a new IDR for this purpose. Signed-off-by:

The callback from vchi_mmal to the client was growing lots of extra parameters. Consolidate them into a single struct instead of growing the list further. The struct is associated with the client buffer, therefore there are various changes to setup various containers for the struct, and pass the appropriate members. Signed-off-by:

The timeout period for VPU communications is a useful thing to extend when debugging. Set it via a define, rather than a magic number buried in the code. Signed-off-by:

As 3 goto level referring to same common code, those can be accomodated with a single goto level and renameing it to unpin_pages. Set the -ERRNO when returning partial mapped pages in more appropriate place. When dma_map_sg() failed, the previously allocated memory was not freed properly. This is corrected now. Signed-off-by:

In 2019, we introduced pin_user_pages*() and now we are converting get_user_pages*() to the new API as appropriate. [1] & [2] could be referred for more information.

First, convert set_page_dirty() to set_page_dirty_lock() Second, there is an interval in there after set_page_dirty() and before put_page(), in which the device could be running and setting pages dirty. Moving set_page_dirty_lock() after dma_unmap_sg(). Signed-off-by:

The Xilinx Clocking Wizard driver uses the devm_ioremap_resource function, but does not specify a dependency on IOMEM in Kconfig. This causes a build failure on architectures without IOMEM, for example, UML (notably with make allyesconfig). Fix this by making CONFIG_COMMON_CLK_XLNX_CLKWZRD depend on CONFIG_IOMEM. Signed-off-by:

Drivers should not use legacy power management as they have to manage power states and related operations, for the device, themselves. This driver was handling them with the help of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device(), etc. With generic PM, all essentials will be handled by the PCI core. Driver needs to do only device-specific operations. The driver was also using pci_enable_wake(...,..., 0) to disable wake. Use device_wakeup_disable() instead. Compile-tested only. Signed-off-by:

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, but the implementation in this driver returns an 'int'. Fix this by returning 'netdev_tx_t' in this driver too and usind 'NETDEV_TX_OK' instead of 0 accordingly. Signed-off-by:
