This is essentially a revert of 86f69fe9 ("Staging: workaround build system bug"), but to call it a revert would imply it was wrong -- rather it seems more like it is just no longer required anymore. It doesn't list the full details of the failing use case, but the most obvious would appear to be a "make allnoconfig" that subsequently had set just CONFIG_STAGING=y in the .config file, to give: paul@builder:~/git/linux-head$ grep STAGING ../staging-allno/.config CONFIG_STAGING=y # CONFIG_STAGING_MEDIA is not set # CONFIG_STAGING_BOARD is not set paul@builder:~/git/linux-head$ After building this .config (on ARM, just to be different), we see that built-in.o is created, and the final vmlinux links OK: paul@builder:~/git/linux-head$ ls -l ../staging-allno/drivers/staging/built-in.o -rw-rw-r-- 1 paul paul 257 Nov 16 18:06 ../staging-allno/drivers/staging/built-in.o paul@builder:~/git/linux-head$ file ../staging-allno/drivers/staging/built-in.o ../staging-allno/drivers/staging/built-in.o: ELF 32-bit LSB relocatable, ARM, version 1, not stripped paul@builder:~/git/linux-head$ nm ../staging-allno/drivers/staging/built-in.o nm: ../staging-allno/drivers/staging/built-in.o: no symbols paul@builder:~/git/linux-head$ ls -l ../staging-allno/vmlinux -rwxrwxr-x 1 paul paul 1236326 Nov 16 18:07 ../staging-allno/vmlinux paul@builder:~/git/linux-head$ I also tested an "allmodconfig" and did not see any problems there either. Switching back to x86-64 and testing several things there didn't show any issues either. So it appears we do not need to carry the workaround in tree any longer.

This patch continues the implementation of reinterpreting stop_arg when stop_src == TRIG_NONE for national instruments cdio output on e/m-series devices. This is part of a series of patches that allow a user to have a specific buffer repeated as-is indefinitely. The contents of the DMA buffer can be left static or changed by the user via mmap access to the DMA buffer. If the contents are changed by the user, additional munging is not performed by the driver and only a single call to comedi_mark_buffer_written should be done. The original behavior is preserved when stop_arg == 0, as would be the prior use case. As opposed to analog output, this patch is relatively simple. First, the digital output capabilities are much more limited/simple as compared to the analog output device on NI e/m-series hardware, and second, this patch relies on changes made with the earlier patch to accomplish limiting the DMA buffer transfer.

This patch implements ni_ao_cmd much more closely organized like NI MHDDK examples and DAQ-STC pseudo-code. Adds comments with some more specific references to the DAQ-STC. For stop_src==TRIG_NONE (continuous output mode of entire buffer), the count for the UC counter was corrected to represent the maximum count possible (0xffffff). Prior behavior for stop_src=TRIG_NONE did not actually follow the DAQ-STC. Furthermore, stop_src==TRIG_NONE now correctly uses code specialized for either m-series or e-series devices. It should be noted that stop_src==TRIG_NONE does _not_ with this patch (or with prior behavior in ni_mio_common) actually implement true continuous output. Rather, the output is simply configured to operate as a single buffer output, but where the buffer is as large as is possible with NI-STC hardware. Signed-off-by: Spencer E.

Bits NISTC_AO_CMD1_DAC0_UPDATE_MODE and NISTC_AO_CMD1_DAC1_UPDATE_MODE are now saved in the local copy of the AO_CMD1 register. This is more appropriate than prior methods of setting these bits specifically _both_ in the ni_ao_cmd configuration function _and_ the ni_ao_inttrig trigger function. With this patch, the bits are only specifically called out now in the ni_ao_cmd configuration function. In the ni_ao_inttrig trigger function, only the UI_ARM, UC_ARM, BC_ARM bits of the ao_cmd1 register are specifically called out. Each of these bits is a strobe bit, while the DAC[0-1]_UPDATE_MODE bits are simple write bits. Signed-off-by: Spencer E.

This change enables the mite DMA controller to only transfer the amount of data needed by a command. By default, the old behavior of transferring the entire comedi DMA data buffer is still in effect. These changes allow a command to only transmit a limited portion of that data buffer as needed. This patch begins to reinterprets stop_arg when stop_src == TRIG_NONE to allow the user to specify the length of the buffer that should be repeated. The intent is to allow a user to have a specific buffer repeated as-is indefinitely. The contents of the DMA buffer can be left static or changed by the user via mmap access to the DMA buffer.

Generally, the CR_CHAN macro is/should be used to access the relevant bits for channel identification in cmd->*_arg when the corresponding cmd->*_src==TRIG_EXT, including cmd->convert_arg in this case. This patch does not fix a bug per se, as NISTC_AI_MODE1_CONVERT_SRC() already masks the value sufficiently, but using CR_CHAN() here makes the code clearer as it avoids passing some irrelevant bits to NISTC_AI_MODE1_CONVERT_SRC() in the first place.

Currently we can only import dma buf fd's to get ion_handle. Adding support to import dma buf handles to support kernel specific use cases. An example use case is in linux platforms such as Tizen, in which DRM-GEM is used for buffer management for graphics. It has gem_handle corresponding to a buffer and uses gem_name for sharing the buffer with other processes. However,it also uses dma_buf fd for 3d operations. For wayland, there are multiple calls for gem_handle to dma_buf fd conversion. So, we store dma_buf associated with buffer. But, there is no api for getting ion_handle from dma_buf. This patch exposes api to retrieve the ion handle from dma_buf for similar use cases. With this patch, we can integrate ION within DRM-GEM for buffer management and dma_buf sharing.
