We are about to rely on TRCDEVARCH for detecting the ETM and its architecture version, falling back to TRCIDR1 if the former is not implemented (in older broken implementations). Also, we use the architecture version information to make some decisions. Streamline the architecture version handling by adding helpers.

etm4_get_access_type() calculates the exception level bits for use in address comparator registers. This is also used by the TRCVICTLR register by shifting to the required position. This patch cleans up the logic to make etm4_get_access_type() calculate a generic mask which can be used by all users by shifting to their field. No functional changes intended.

We rely on the ETM architecture version to decide whether Secure EL2 is available on the CPU for excluding the level for address comparators and viewinst main control register. We must instead use the TRCDIDR3.EXLEVEL_S field to detect the supported levels. Link: https://lore.kernel.org/r/20210110224850.1880240-16-suzuki.poulose@arm.comSigned-off-by:

Some of the management registers in ETMv4.x are not accessible via system register instructions. Thus we must hide the sysfs files exposing them to the userspace, to prevent system crashes. This patch adds an is_visible() routine to control the visibility at runtime for the registers that may not be accessed.

ETM architecture defines the system instructions for accessing via register accesses. Add basic support for accessing a given register via system instructions. We split the list of registers as : 1) Accessible only from memory mapped interface 2) Accessible from system register instructions. All registers are accessible via the memory-mapped interface. However, some registers are not accessible via the system instructions. This list is then used to further filter out the files we expose via sysfs.

Some of the ETM management registers are not accessible via system instructions. Thus we need to filter accesses to these registers depending on the access mechanism for the ETM at runtime. The driver can cope with this for normal operation, by regular checks. But the driver also exposes them via sysfs, which now needs to be removed. So far, we have used the generic coresight sysfs helper macros to export a given device register, defining a "show" operation per register. This is not helpful to filter the files at runtime, based on the access. In order to do this dynamically, we need to filter the attributes by offsets and hard coded "show" functions doesn't make this easy. Thus, switch to extended attributes, storing the offset in the scratch space. This allows us to implement filtering based on the offset and also saves us some text size. This will be later used for determining a given attribute must be "visible" via sysfs.

Convert all register accesses from etm4x driver to use a wrapper to allow switching the access at runtime with little overhead. co-developed by sed tool ;-), mostly equivalent to : s/readl\(_relaxed\)\?(drvdata->base + \(.*\))/etm4x_\1_read32(csdev, \2) s/writel\(_relaxed\)\?(\(.*\), drvdata->base + \(.*\))/etm4x_\1_write32(csdev, \2, \3) We don't want to replace them with the csdev_access_* to avoid a function call for every register access for system register access. This is a prepartory step to add system register access later where the support is available.

Prepare the TPIU driver to make use of the CoreSight device access abstraction layer. The driver touches the device even before the coresight device is registered. Thus we could be accessing the devices without a csdev. As we are about to use the abstraction layer for accessing the device, pass in the access directly to avoid having to deal with the un-initialised csdev.

We are about to introduce support for sysreg access to ETMv4.4+ component. Since there are generic routines that access the registers (e.g, CS_LOCK/UNLOCK , claim/disclaim operations, timeout) and in order to preserve the logic of these operations at a single place we introduce an abstraction layer for the accesses to a given device.
