2017-08-22drm/i915: Re-enable per-engine reset for BroxtonMichel Thierry1-1/+0
The corruption in CSB mmio reads we were seeing has been tracked down to incorrectly touching forcewake of all domains, following an engine reset. It is still a mistery why we only catched this in Broxton, since it could happen in any platform. With that fix already merged, commit 4055dc75d6b5 ("drm/i915: Stop touching forcewake following a gen6+ engine reset"), lets try to enable per-engine resets in Broxton one more time. This reverts commit f188258bde0f ("drm/i915: Disable per-engine reset for Broxton").

2017-06-20drm/i915: Modify error handler for per engine hang recoveryMichel Thierry1-1/+4
This is a preparatory patch which modifies error handler to do per engine hang recovery. The actual patch which implements this sequence follows later in the series. The aim is to prepare existing recovery function to adapt to this new function where applicable (which fails at this point because core implementation is lacking) and continue recovery using legacy full gpu reset. A helper function is also added to query the availability of engine reset. A subsequent patch will add the capability to query which type of reset is present (engine -> full -> no-reset) via the get-param ioctl. It has been decided that the error events that are used to notify user of reset will only be sent in case if full chip reset. In case of just single (or multiple) engine resets, userspace won't be notified by these events. Note that this implementation of engine reset is for i915 directly submitting to the ELSP, where the driver manages the hang detection, recovery and resubmission. With GuC submission these tasks are shared between driver and firmware; i915 will still responsible for detecting a hang, and when it does it will have to request GuC to reset that Engine and remind the firmware about the outstanding submissions. This will be added in different patch. v2: rebase, advertise engine reset availability in platform definition, add note about GuC submission. v3: s/*engine_reset*/*reset_engine*/. (Chris) Handle reset as 2 level resets, by first going to engine only and fall backing to full/chip reset as needed, i.e. reset_engine will need the struct_mutex. v4: Pass the engine mask to i915_reset. (Chris) v5: Rebase, update selftests. v6: Rebase, prepare for mutex-less reset engine. v7: Pass reset_engine mask as a function parameter, and iterate over the engine mask for reset_engine. (Chris) v8: Use i915.reset >=2 in has_reset_engine; remove redundant reset logging; add a reset-engine-in-progress flag to prevent concurrent resets, and avoid dual purposing of reset-backoff. (Chris) v9: Support reset of different engines in parallel (Chris) v10: Handle reset-engine flag locking better (Chris) v11: Squash in reporting of per-engine-reset availability.

2017-02-13drm/i915: Provide a hook for selftestsChris Wilson1-7/+24
Some pieces of code are independent of hardware but are very tricky to exercise through the normal userspace ABI or via debugfs hooks. Being able to create mock unit tests and execute them through CI is vital. Start by adding a central point where we can execute unit tests and a parameter to enable them. This is disabled by default as the expectation is that these tests will occasionally explode. To facilitate integration with igt, any parameter beginning with i915.igt__ is interpreted as a subtest executable independently via igt/drv_selftest. Two classes of selftests are recognised: mock unit tests and integration tests. Mock unit tests are run as soon as the module is loaded, before the device is probed. At that point there is no driver instantiated and all hw interactions must be "mocked". This is very useful for writing universal tests to exercise code not typically run on a broad range of architectures. Alternatively, you can hook into the live selftests and run when the device has been instantiated - hw interactions are real. v2: Add a macro for compiling conditional code for mock objects inside real objects. v3: Differentiate between mock unit tests and late integration test. v4: List the tests in natural order, use igt to sort after modparam. v5: s/late/live/ v6: s/unsigned long/unsigned int/ v7: Use igt_ prefixes for long helpers. v8: Deobfuscate macros overriding functions, stop using -I$(src) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170213171558.20942-1-chris@chris-wilson.co.uk

2017-01-04drm/i915: actually drive the BDW reserved IDsPaulo Zanoni1-0/+1
Back in 2014, commit fb7023e0e248 ("drm/i915: BDW: Adding Reserved PCI IDs.") added the reserved PCI IDs in order to try to make sure we had working drivers in case we ever released products using these IDs (since we had instances of this type of problem in the past). The problem is that the patch only touched the macros used by early-quirks.c and by the user space components that rely on i915_pciids.h, it didn't touch the macros used by i915_pci.c. So we correctly handled the stolen memory for these theoretical IDs, but we didn't actually drive the devices from i915.ko. So this patch fixes the original commit by actually making i915.ko drive these IDs, which was the goal. There's no information on what would be the GT count on these IDs, so we just go with the safer intel_broadwell_info, at the risk of ignoring a possibly inexistent BSD2_RING. I did some checking, and it seems that these IDs are driven by intel-gpu-tools, xf86-video-intel and libdrm (since they contain old copies of i915_pciids.h), but they are not checked by mesa. The alternative to this patch would be to just assume we're actually never going to use these IDs, and then remove them from our ID lists and make sure our user space components sync the latest i915_pciids.h copy. I'm fine with either approaches, as long as we make sure that every component tries to drive the same list of PCI IDs. Fixes: fb7023e0e248 ("drm/i915: BDW: Adding Reserved PCI IDs.")

2016-11-16drm/i915/bxt: Broxton decoupled MMIOPraveen Paneri1-0/+1
Decoupled MMIO is an alternative way to access forcewake domain registers, which requires less cycles for a single read/write and avoids frequent software forcewake. This certainly gives advantage over the forcewake as this new mechanism “decouples” CPU cycles and allow them to complete even when GT is in a CPD (frequency change) or C6 state. This can co-exist with forcewake and we will continue to use forcewake as appropriate. E.g. 64-bit register writes to avoid writing 2 dwords separately and land into funny situations. v2: - Moved platform check out of the function and got rid of duplicate functions to find out decoupled power domain (Chris) - Added a check for forcewake already held and skipped decoupled access (Chris) - Skipped writing 64 bit registers through decoupled MMIO (Chris) v3: - Improved commit message with more info on decoupled mmio (Tvrtko) - Changed decoupled operation to enum and used u32 instead of uint_32 data type for register offset (Tvrtko) - Moved HAS_DECOUPLED_MMIO to device info (Tvrtko) - Added lookup table for converting fw_engine to pd_engine (Tvrtko) - Improved __gen9_decoupled_read and __gen9_decoupled_write routines (Tvrtko) v4: - Fixed alignment and variable names (Chris) - Write GEN9_DECOUPLED_REG0_DW1 register in just one go (Zhe Wang) v5: - Changed HAS_DECOUPLED_MMIO() argument name to dev_priv (Tvrtko) - Sanitize info->had_decoupled_mmio at init (Chris) Signed-off-by: Zhe Wang <zhe1.wang@intel.com> Signed-off-by: Praveen Paneri <praveen.paneri@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1479230360-22395-1-git-send-email-praveen.paneri@intel.com
2016-11-14drm/i915: rename preliminary_hw_support to alpha_supportJani Nikula1-3/+4
The term "preliminary hardware support" has always caused confusion both among users and developers. It has always been about preliminary driver support for new hardware, and not so much about preliminary hardware. Of course, initially both the software and hardware are in early stages, but the distinction becomes more clear when the user picks up production hardware and an older kernel to go with it, with just the early support we had for the hardware at the time the kernel was released. The user has to specifically enable the alpha quality *driver* support for the hardware in that specific kernel version. Rename preliminary_hw_support to alpha_support to emphasize that the module parameter, config option, and flag are about software, not about hardware. Improve the language in help texts and debug logging as well. This appears to be a good time to do the change, as there are currently no platforms with preliminary^W alpha support.
