2020-01-23intel_reg: Use static iteratorPetri Latvala
Convert open-coded for loops to __for_each_static_engine. That takes care of the last direct user of intel_execution_engines2. More work is needed to make intel_reg support dynamically queried engines but this restores the old functionality.

2019-08-29lib/intel_mmio: add additional api for multiple devicesDaniel Mrzyglod
Library was limited for reading registers for only one device at a time in igt tests. Changes in this patch give as oportunity to test multiple devices in the same time. v8: pack and rename structure, remove unnecessary field v7: remove unnecessary code v6: Reword patch. Cosmetic changes.

2019-03-29Revert "lib/igt_device: Move intel_get_pci_device under igt_device"Ville Syrjälä
One significant usecase for intel_reg/etc. is to be able to examine the hardware state *before* loading the driver. If the tool forces the driver to load we've totally lost that capability. This reverts commit 8ae86621d6fff60b6e20c6b0f9b336785c935b0f.

2019-03-20lib/igt_device: Move intel_get_pci_device under igt_deviceMichał Winiarski
It allows us to make things a little bit more generic. Also, we now require fd rather than doing guesswork when it comes to pci address. v2: Use readlinkat rather than string concat, move stuff around, provide a version that does not assert. (Chris) v3: Print addr on failure, avoid assignment in conditionals.

2018-09-05intel_reg: Fix truncate string in the snprintfRodrigo Siqueira
This patch fix the following GCC warning: ../tools/intel_reg.c: In function ‘dump_decode’: ../tools/intel_reg.c:203:41: warning: ‘snprintf’ output may be truncated before the last format character [-Wformat-truncation=] snprintf(decode, sizeof(decode), "\n%s", bin); [..] ../tools/intel_reg.c:200:40: warning: ‘%s’ directive output may be truncated writing up to 1023 bytes into a region of size 1022 [-Wformat-truncation=] snprintf(decode, sizeof(decode), " (%s)\n%s", tmp, bin); [..] ../tools/intel_reg.c:200:4: note: ‘snprintf’ output between 5 and 2051 bytes into a destination of size 1024 snprintf(decode, sizeof(decode), " (%s)\n%s", tmp, bin); [..] The decode[] variable contains concatenated contents of bin[] and tmp[], both of which are allocated as 1024 bytes. Allocating 1024 chars for bin[] seems like an overkill, since all it ever holds it the output of to_binary(). to_binary outputs fixed format: -------------------------------------------------------------------- 24 16 8 0 1 1 0 1 1 1 1 0 1 0 1 0 1 1 0 1 1 0 1 1 1 1 1 0 1 1 1 0 1 1 1 1 -------------------------------------------------------------------- Which is 138 chars long (sans the new line). We can limit the size of char bin[] to that number (-ish), and then slightly bump the size of decode[] to accommodate for combined sizes of tmp[] and bin[].

2016-06-30lib: Start weaning off defunct intel_chipset.hChris Wilson
Several years ago we made the plan of only having one canonical source for i915_pciids.h, the kernel and everyone importing their definitions from that. For consistency, we style the intel_device_info after the kernel, most notably using a generation mask and a per-codename bitfield. This first step converts looking up the generation for a devid tree from a massive if(devid)-chain to a (cached) table lookup. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
