2019-05-01habanalabs: rename functions to improve code readabilityOded Gabbay
This patch renames four functions in the ASIC-specific functions section, so it will be easier to differentiate them from the generic kernel functions with the same name. This will help in future code reviews, to make sure we don't use the kernel functions directly. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-04-30habanalabs: remove call to cs_parser()Dalit Ben Zoor
There is no need to parse the command submission when doing memset of the device memory using the DMA engine because only the driver calls the memset function and therefore, the CS is trusted and doesn't require validation and patching.

2019-04-28habanalabs: Use single pool for CPU accessible host memoryTomer Tayar
The device's CPU accessible memory on host is managed in a dedicated pool, except for 2 regions - Primary Queue (PQ) and Event Queue (EQ) - which are allocated from generic DMA pools. Due to address length limitations of the CPU, the addresses of all these memory regions must have the same MSBs starting at bit 40. This patch modifies the allocation of the PQ and EQ to be also from the dedicated pool, to ensure compliance with the limitation.

2019-04-28habanalabs: return old dram bar address upon changeOded Gabbay
This patch changes the ASIC interface function that changes the DRAM bar window. The change is to return the old address that the DRAM bar pointed to instead of an error code. This simplifies the code that use this function (mainly in debugfs) to restore the bar to the old setting. This is also needed for easier support in future ASICs.

2019-04-25habanalabs: rename restore to ctx_switch when appropriateOded Gabbay
This patch only does renaming of certain variables and structure members, and their accompanied comments. This is done to better reflect the actions these variables and members represent. There is no functional change in this patch. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-04-22habanalabs: use ASIC functions interface for rreg/wregOded Gabbay
This patch slightly changes the macros of RREG32 and WREG32, which are used when reading or writing from registers. Instead of directly calling a function in the common code from these macros, the new code calls a function from the ASIC functions interface. This change allows us to share much more code between real ASICs and simulators, which in turn reduces the maintenance burden and the chances for forgetting to port code between the ASIC files. The patch also implements the hl_poll_timeout macro, instead of calling the generic readl_poll_timeout macro. This is required to allow use of this macro in the simulator files. As a result from this change, more functions in goya.c are shared with the simulator and therefore, should not be defined as static. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-04-21uapi/habanalabs: add missing fields in bmon paramsOded Gabbay
This patch adds missing fields of start address 0 and 1 in the bmon parameter structure that is received from the user in the debug IOCTL. Without these fields, the functionality of the bmon trace is broken, because there is no configuration of the base address of the filter of the bus monitor. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-04-21habanalabs: re-factor goya_parse_cb_no_ext_queue()Oded Gabbay
This patch re-factors goya_parse_cb_no_ext_queue() to make it more readable by inverting the check inside the first if statement so the bulk of the function won't be inside an if statement. The patch also fixes a spelling error in the name of the function. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-04-10habanalabs: Cancel pr_fmt() definition dependency on includes orderTomer Tayar
pr_fmt() should be defined before including linux/printk.h, either directly or indirectly, in order to avoid redefinition of the macro. Currently the macro definition is in habanalabs.h, which is included in many files, and that makes the addition/reorder of includes to be prone to compilation errors. This patch cancels this dependency by defining the macro only in the few source files that use it. Signed-off-by: Tomer Tayar <ttayar@habana.ai> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-05-02coresight: funnel: Support static funnelLeo Yan
Since CoreSight hardware topology can use a 'hidden' funnel in the trace data path, this kind funnel doesn't have register for accessing and is used by default from hardware design perspective. Below is an example for related hardware topology: +------+ +------+ | cpu0 |->| ETM |-\ +------+ +------+ \-> +--------+ +-----+ ...... | Funnel |->| ETF |-\ Hidden funnel +------+ +------+ /-> +--------+ +-----+ \ | | cpu3 |->| ETM |-/ \ V +------+ +------+ \-> +--------+ | Funnel |-> ... +------+ +------+ /-> +--------+ | cpu4 |->| ETM |-\ / +------+ +------+ \-> +--------+ +-----+ / ...... | Funnel |->| ETF |-/ +------+ +------+ /-> +--------+ +-----+ | cpu7 |->| ETM |-/ +------+ +------+ The CoreSight funnel driver only supports dynamic funnel with registration register resource, thus it cannot support for the static funnel case and it's impossible to create trace data path for this case. This patch is to extend CoreSight funnel driver to support both for static funnel and dynamic funnel. For the dynamic funnel it reuses the code existed in the driver, for static funnel the driver will support device probe if without providing register resource and the driver skips registers accessing when detect the register base is NULL.

2019-05-02dt-bindings: arm: coresight: Unify funnel DT bindingLeo Yan
Following the same fashion with replicator DT binding, this patch is to unify the DT binding for funnel to support static and dynamic modes; finally we get the funnel DT binding as below: Before patch: Static funnel, aka. non-configurable funnel: Not supported; Dynamic funnel, aka. configurable funnel: "arm,coresight-funnel", "arm,primecell"; After patch: Static funnel: "arm,coresight-static-funnel"; Dynamic funnel: "arm,coresight-dynamic-funnel", "arm,primecell"; "arm,coresight-funnel", "arm,primecell"; (obsolete) At the end of this patch, it gives an example for static funnel DT binding, and updates the dynamic funnel example.

2019-05-02dt-bindings: arm: coresight: Add new compatible for static replicatorLeo Yan
CoreSight uses below bindings for replicator: Dynamic replicator, aka. configurable replicator: "arm,coresight-dynamic-replicator", "arm,primecell"; Static replicator, aka. non-configurable replicator: "arm,coresight-replicator"; The compatible string "arm,coresight-replicator" is not an explicit naming to express the replicator is 'static'. To unify the naming convention, this patch introduces a new compatible string "arm,coresight-static-replicator" for the static replicator; the compatible string "arm,coresight-replicator" is kept for backward compatibility, but tag it as obsolete and suggest to use the new compatible string. As result CoreSight replicator have below bindings: Dynamic replicator: "arm,coresight-dynamic-replicator", "arm,primecell"; Static replicator: "arm,coresight-static-replicator"; "arm,coresight-replicator"; (obsolete) Signed-off-by: Leo Yan <leo.yan@linaro.org> Reviewed-by: Suzuki K Poulose <suzuki.poulose@arm.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
