virtio: don't allocate vqs when names[i] = NULL

2019-01-22T20:09:52+00:00

commit a229989d975eb926076307c1f2f5e4c6111768e7 upstream. Some vqs may not need to be allocated when their related feature bits are disabled. So callers may pass in such vqs with "names = NULL". Then we skip such vq allocations. Signed-off-by: Wei Wang Signed-off-by: Michael S.

remoteproc: qcom: q6v5-mss: Register segments/dumpfn for coredump

2018-10-19T19:54:03+00:00

Register the MDT segments, custom dumpfn and private data with the remoteproc core dump functionality. Signed-off-by: Sibi Sankar Signed-off-by: Bjorn Andersson

remoteproc: qcom: q6v5-mss: Add custom dump function for modem

2018-10-19T19:54:03+00:00

The per segment dump function is responsible for loading the mba before device memory segments associated with coredump can be populated and for cleaning up the resources post coredump. Signed-off-by: Sibi Sankar Signed-off-by: Bjorn Andersson

remoteproc: qcom: q6v5-mss: Refactor mba load/unload sequence

2018-10-19T19:54:02+00:00

Refactor re-useable parts of mba load/unload sequence into mba_load and mba_reclaim respectively. This is done in order to prevent code duplication for modem coredump, which requires the mba to be loaded before dumping the segments. The following changes in functionality are intended: * Add software bypass to avoid high MX current in mpss error path. * Remove the proxy votes of clk/regs only after the active/reset clks/regs. * Reclaim MBA memory after mpss_load failure in mba_reclaim func. * Set/Unset the dump_mba_loaded flag on mba_load/mba_reclaim respectively.

remoteproc: Add mechanism for custom dump function assignment

2018-10-19T19:53:55+00:00

This patch adds a mechanism for assigning each rproc dump segment with a custom dump function and private data. The dump function is to be called for each rproc segment during coredump if assigned.

remoteproc: Introduce custom dump function for each remoteproc segment

Introduce custom dump function and private data per remoteproc dump segment. The dump function is responsible for filling the device memory segment associated with coredump Signed-off-by: Sibi Sankar Signed-off-by: Bjorn Andersson

remoteproc: modify vring allocation to rely on centralized carveout allocator

2018-10-15T06:37:40+00:00

Current version of rproc_alloc_vring function supports only dynamic vring allocation. This patch allows to allocate vrings based on memory region declatation. Vrings are now manage like memory carveouts, to communize memory management code in rproc_alloc_registered_carveouts(). Allocated buffer is retrieved in rp_find_vq() thanks to rproc_find_carveout_by_name() functions for. This patch sets vrings names to vdev"x"vring"y" with x vdev index in resource table and y vring index in vdev. This will be updated when name will be associated to vdev in firmware resource table.

remoteproc: qcom: q6v5: shore up resource probe handling

2018-10-10T06:13:32+00:00

Commit d5269c4553a6 ("remoteproc: qcom: q6v5: Propagate EPROBE_DEFER") fixed up our probe code to handle -EPROBE_DEFER, but it ignored one of our interrupts, and it also didn't really handle all the other error codes you might get (e.g., with a bad DT definition). Handle those all explicitly. Fixes: d5269c4553a6 ("remoteproc: qcom: q6v5: Propagate EPROBE_DEFER") Reviewed-by: Douglas Anderson Signed-off-by: Brian Norris Signed-off-by: Bjorn Andersson

remoteproc: qcom: qcom_q6v5_adsp: Fix some return value check

2018-10-10T06:08:07+00:00

In case of error, the functions devm_kcalloc() and devm_ioremap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. Also removed -EPROBE_DEFER check since devm_kcalloc never return this error.

remoteproc: modify rproc_handle_carveout to support pre-registered region

2018-10-10T05:41:04+00:00

In current version rproc_handle_carveout() function registers carveout for allocation. This patch extends rproc_handle_carveout() function to support pre-registered region. Match is done on region name, then requested device address and length are checked. If match found, pre-registered region is associated with resource table request. If no name match found, new carveout is registered for allocation. Signed-off-by: Loic Pallardy Signed-off-by: Bjorn Andersson
