v2: In this series I've removed module management and hand device classes
filtering (udev filters are now used in this case). Lsgpu was
simplified (some options were unreadable and they were removed).
Still migration to gtkdoc is necessary which will be made in v3.
v3: Change device scanning to drm subsystem with getting parent
according to Daniel Vetter suggestion. Splitting to two patches
and adding gtk-doc documentation.
v4: Extending and fixing documentation. Adding reviewers forgotten
in v3.
v5: Adding .igtrc support. Fixing code according to review comments.
Lsgpu device selection order now uses same search strategy
like IGT core. It uses --device / IGT_DEVICE and .igtrc
order accordingly to verify tests device selection works as expected.
Zbigniew Kempczyński (2):
Introduce device selection API
Add device selection for IGT

Then contextual filter is chosen + * depending on filter name. + * + * Direct device selection filter must be: + * + * |[<!-- language="plain" --> + * subsystem:/sys + * ]| + * + * So, when user passes filter which looks like follows: + * |[<!-- language="plain" --> + * - drm:/sys/devices/pci0000:00/0000:00:02.0/drm/card0 + * - pci:/sys/devices/pci0000:00/0000:00:02.0 + * - platform:/sys/devices/platform/vgem + * ]| + * + * device from array which has subsystem and sys path will be returned. + * + * When /sys is not specified after colon contextual filters are taken + * into account. Drm device occurs in the system when appropriate module + * is loaded and device is detected (or exposed for platform devices). Loading + * drivers in different order can be problematic from CI point of view, where + * expectation is to get same device especially when multiple gpu devices + * exists in the system. For such devices its parent location on pci bus + * is constant and allows appropriate device selection using for example + * vendor / device ids. + * + * For tests which opens more than one device device filter collection API + * can be used. You can add a filter to the array using igt_device_filter_add(), + * get the nth filter stored using igt_device_filter_get() and get + * #igt_device_card using igt_device_card_match() with that filter. + * + * Implemented filters: + * + * - drm: get drm /dev/dri/... device directly + * + * |[<!-- language="plain" --> + * drm:/dev/dri/... + * ]| + * + * - pci: select device using pci properties + * |[<!-- language="plain" --> + * pci:[vendor=%04x/name][,device=%04x][,card=%d] + * ]| + * + * Filter allows device selection using vendor (hex or name), device id + * (hex) and nth-card from all matches. For example if there're 4 pci + * cards installed (let two cards have 1234 and other two 1235 device id, + * all of them of vendor Intel) you can select one using: + * + * |[<!-- language="plain" --> + * pci:vendor=Intel,device=1234,card=0 + * ]| + * + * or + * + * |[<!-- language="plain" --> + * pci:vendor=8086,device=1234,card=0 + * ]| + * + * This takes first device with 1234 id for Intel vendor (8086). + * + * |[<!-- language="plain" --> + * pci:vendor=Intel,device=1234,card=1 + * ]| + * + * or + * + * |[<!-- language="plain" --> + * pci:vendor=8086,device=1234,card=1 + * ]| + * + * It selects second one. + * + * As order on pci bus doesn't change (unless you'll add new device or + * reorder existing one) device selection using this filter will always + * return you same device regardless module loading time. + * + * - vgem: select virtual gem device + * + * |[<!-- language="plain" --> + * vgem:[card=%d] + * ]| + * + * For example: + * + * |[<!-- language="plain" --> + * vgem: + * vgem:card=0 + * ]| + * + * Both selects first vgem device (no idea if more than one device will + * be visible, if yes use card= argument to point right one). + * + * - vkms: select virtual kms device + * + * |[<!-- language="plain" --> + * vkms:[card=%d] + * ]| + * + * For example: + * + * |[<!-- language="plain" --> + * vkms: + * vkms:card=0 + * ]| + * + * Both selects first vkms device.

At the moment Rasperry PI has only + * one gpu, but filter is ready if there will be more. + * + * # lsgpu + * + * The devices can be scanned and displayed using 'lsgpu' tool. Tool also + * displays properties and sysattrs (-p switch, means print detail) which + * can be used during filter implementation. + * + * Tool can also be used to try out filters. + * To select device use '-d' or '--device' argument like: + * + * |[<!-- language="plain" --> + * ./lsgpu -d 'pci:vendor=Intel' + * === Device filter list === + * [ 0]: pci:vendor=Intel + + * === Testing device open === + * subsystem : pci + * chipset : 1 + * drm card : /dev/dri/card0 + * drm render : /dev/dri/renderD128 + * Device /dev/dri/card0 successfully opened + * Device /dev/dri/renderD128 successfully opened + * ]| + * + * Additionally lsgpu tries to open the card and render nodes to verify + * permissions.

I have a question about lsgpu usage. '-p' prints all devices, but there is not information in help about that '-d' used without '-p' filters and prints details about particular device Mixing '-p' and '-d' has no affect - we still see all devices, not filtered ones.

This was my first thought that I am doing it wrong. I forgot to add 'platform:'. Code looks good, thanks for addressing comments from previous revision.

I can't imagine any real use-cases of the current implementation. Instead I would probably just go with writing what I have described in the previous iteration. How about splitting the *_with_nth_filter() into a separate patch and sending it on its own, as a reference? Then we can leave the design of this bit of the interface to people that will actually consume it. > +/** > + * drm_open_card: > + * @card: pointer to igt_device_card structure > + * > + * Open /dev/dri/cardX device using multi-device selection API. > + * > + * Require filled @card argument (see igt_device_card_match() function). > + * > + * An open DRM fd or -1 on error > + */ > +int drm_open_card(struct igt_device_card *card) > +{ > + if (!card || !strlen(card->card)) > + return -1;

Without reiterating the filters and matching chipset it is not possible. Above function has a bug, I've fixed it. So: # kms_prime --device vgem: --device pci: or # kms_prime --device pci: --device vgem: will work properly when I'll push the new patchset. I would like to rewrite tests adopting new API partially, not making revolution within tests now. <cut> > $ ./core_auth --r getclient-simple --device vkms > > IGT-Version: 1.24-g64068440 (x86_64) (Linux: 5.2.10- > 250.vanilla.knurd.1.fc30.x86_64 x86_64) > Starting subtest: getclient-simple > Test requirement not met in function drm_open_driver, file > ../lib/drmtest.c:569: > Test requirement: !(fd<0) > No known gpu found for chipset flags 0x4294967291 (any) > Last errno: 2, No such file or directory > Subtest getclient-simple: SKIP (0.002s) > Test requirement not met in function drm_open_driver, file > ../lib/drmtest.c:569: > Test requirement: !(fd<0) > No known gpu found for chipset flags 0x4294967291 (any) > > Which says nothing about filters.

Currently device selection code is not verbose and in case of problems you're not informed what's wrong. I will add debug / error messages to the code. <cut> > +int drm_open_card_with_nth_filter(int num, int chipset) <cut> > +int drm_open_render_with_nth_filter(int num, int chipset) > I am still not completely happy with those. > > I can't imagine any real use-cases of the current implementation. > Instead I would probably just go with writing what I have described in > the previous iteration. > > How about splitting the *_with_nth_filter() into a separate patch and > sending it on its own, as a reference?
