Perf measurements rely on CPU and engine timestamps to correlate events of interest across these time domains. Current mechanisms get these timestamps separately and the calculated delta between these timestamps lack enough accuracy. To improve the accuracy of these time measurements to within a few us, add a query that returns the engine and cpu timestamps captured as close to each other as possible.

RCS and CCS engines include several non-register gfxpipe commands in their LRC images. Include these in the dump output so that we can see exactly what's inside the context snapshot. v2: - Include raw instruction header in output - Add 3DSTATE_AMFS_TEXTURE_POINTERS and 3DSTATE_MONOFILTER_SIZE. The first was supposed to be removed in Xe_HPG, and the second by gen12, but both still show up in the RCS LRC. v3: - Sanity check that we don't have numdw > remaining_dw.

For non-RCS engines, nearly all of the LRC state is composed of MI instructions (specifically MI_LOAD_REGISTER_IMM). Providing a dump interface allows us to verify that the context image layout matches what's documented in the bspec, and also allows us to check whether LRC workarounds are being properly captured by the default state we record at startup. For now, the non-MI instructions found in the RCS and CCS engines will dump as "unknown;" parsing of those will be added in a follow-up patch. v2: - Add raw instruction header as well as decoded meaning. (Lucas) - Check that num_dw isn't greater than remaining_dw for instructions that have a "# dwords" field. (Lucas) - Clarify comment about skipping over ppHWSP.

Extracting the common MI_* instructions that can be used with any engine to their own header will make it easier as we add additional engine instructions in upcoming patches. Also, since the majority of GPU instructions (both MI and non-MI) have a "length" field in bits 7:0 of the instruction header, a common define is added for that. Instruction-specific length fields are still defined for special case instructions that have larger/smaller length fields. v2: - Use "instr" instead of "inst" as the short form of "instruction" everywhere. (Lucas) - Include xe_reg_defs.h instead of the i915 compat header. (Lucas) Reviewed-by:

MI_STORE_DATA_IMM can store either dword values or qword values, and can store more than one value if the instruction's length field is large enough. Create explicit defines to specify the number of dwords/qwords to be stored, which will set the instruction length correctly and, if necessary, turn on the 'store qword' bit. While we're here, also replace an open-coded version of MI_STORE_DATA_IMM with the common macros. Bspec: 60246 Reviewed-by:

Despite its name, MI_FLUSH_DW instruction can write an immediate value of either dword size or qword size, depending on the 'length' field of the instruction. Since "length" excludes the first two dwords of the instruction, a value of 2 in the length field implies a dword write and a value of 3 implies a qword write. Even in cases where the flush instruction's post-sync operation is set to "no write" we're still expected to size the overall instruction as if we were doing a dword or qword write (i.e., a length of 1 shouldn't be used on modern platforms). Rather than baking a size of "1" into the #define and then adding another unexplained "+ 1" at all the spots where the definition gets used, lets just create MI_FLUSH_IMM_DW and MI_FLUSH_IMM_QW definitions that should be OR'd into the instruction header to make it more explicit what behavior we're requesting.

When MMIO BAR is initially mapped, the driver assumes a single tile device. However, former memory allocations take all tiles into account. First, a common standard for resource usage is needed here. Second, with the next (6th) patch in this series, the MMIO BAR remapping will be done only if a reduced-tile device is attached. Signed-off-by:

Xe driver currently supports 22-bit addresses for MMIO access. Future platforms will have additional MMIO extension with larger address spaces, and to access them, the driver will have to support wider address representation. Please note that while the XE_REG macro is used for MMIO access, XE_REG_EXT macro will be used for MMIO-extension access. Signed-off-by:

It doesn't look like you can mix and match devm_ and drmmm_ for a managed resource. For drmmm the resources are all tracked in drm with its own list, and there is only one devm_ resource for the entire list. If the driver itself also adds some of its own devm resources, then those will be released first. In the case of hwmon the devm_kzalloc will be freed before the drmmm_ action to destroy the mutex allocated within, leading to uaf. Since hwmon itself wants to use devm, rather use that for the mutex destroy. Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/766Signed-off-by:
