cxl: use -Werror only with CONFIG_PPC_WERROR Some developers really like to have -Werror enabled for their code, as it helps to ensure warning free code. Others don't want -Werror, as it (for example) can cause problems when newer (or older) compilers have different sets of warnings, or new warnings can appear just when turning up the warning level (e.g., make W=1 or W=2). Thus, it seems prudent to have the use of -Werror be configurable. It so happens that cxl is only built on PowerPC, and PowerPC already has a nice set of Kconfig options for this, under CONFIG_PPC_WERROR. So let's use that, and the world is a happy place again! (Note that PPC_WERROR defaults to =y, so the common case compile should still be enforcing -Werror.)

cxl: Allow a default context to be associated with an external pci_dev The cxl kernel API has a concept of a default context associated with each PCI device under the virtual PHB. The Mellanox CX4 will also use the cxl kernel API, but it does not use a virtual PHB - rather, the AFU appears as a physical function as a peer to the networking functions. In order to allow the kernel API to work with those networking functions, we will need to associate a default context with them as well. To this end, refactor the corresponding code to do this in vphb.c and export it so that it can be called from the PHB code.

cxl: Support to flash a new image on the adapter from a guest The new flash.c file contains the logic to flash a new image on the adapter, through a hcall. It is an iterative process, with chunks of data of 1M at a time. There are also 2 phases: write and verify. The flash operation itself is driven from a user-land tool. Once flashing is successful, an rtas call is made to update the device tree with the new properties values for the adapter and the AFU(s) Add a new char device for the adapter, so that the flash tool can access the card, even if there is no valid AFU on it.

cxl: Add base builtin support This adds the base cxl support that cannot be built as a module. Specifically it adds the cxl callbacks that are called from the core powerpc mm code which must always exist irrespective of if the cxl module is loaded or not. This is similar to how cell works with CONFIG_SPU_BASE. This adds a cxl_slbia() call (similar to spu_flush_all_slbs()) which checks if the cxl module is loaded and in use, returning immediately if it is not. If it is in use it calls into the cxl SLB invalidation code.

cxl: Add tracepoints This patch adds tracepoints throughout the cxl driver, which can provide insight into: - Context lifetimes - Commands sent to the PSL and AFU and their completion status - Segment and page table misses and their resolution - PSL and AFU interrupts - slbia calls from the powerpc copro_fault code These tracepoints are mostly intended to aid in debugging (particularly for new AFU designs), and may be useful standalone or in conjunction with hardware traces collected by the PSL (read out via the trace interface in debugfs) and AFUs.
