2017-01-12net: thunderx: acpi: fix LMAC initializationVadim Lomovtsev1-5/+6
While probing BGX we requesting appropriate QLM for it's configuration and get LMAC count by that request. Then, while reading configured MAC values from SSDT table we need to save them in proper mapping: BGX[i]->lmac[j].mac = <MAC value> to later provide for initialization stuff. In order to fill such mapping properly we need to add lmac index to be used while acpi initialization since at this moment bgx->lmac_count already contains actual value.

2017-01-12at86rf230: Allow slow GPIO pins for "rstn"Andrey Smirnov1-2/+2
Driver code never touches "rstn" signal in atomic context, so there's no need to implicitly put such restriction on it by using gpio_set_value to manipulate it. Replace gpio_set_value to gpio_set_value_cansleep to fix that. As a an example of where such restriction might be inconvenient, consider a hardware design where "rstn" is connected to a pin of I2C/SPI GPIO expander chip.

This is the deprecated function for when you embedded the framebuffer somewhere else (which breaks refcounting). But Tegra is using drm_framebuffer_remove and a free-standing FB, so this is redundant. One caveat here is that the failure path in the init code still manually cleaned up the fb.

2017-01-12drm/i915: Remove WaDisableLSQCROPERFforOCL KBL workaround.Francisco Jerez2-18/+0
The WaDisableLSQCROPERFforOCL workaround has the side effect of disabling an L3SQ optimization that has huge performance implications and is unlikely to be necessary for the correct functioning of usual graphic workloads. Userspace is free to re-enable the workaround on demand, and is generally in a better position to determine whether the workaround is necessary than the DRM is (e.g. only during the execution of compute kernels that rely on both L3 fences and HDC R/W requests). The same workaround seems to apply to BDW (at least to production stepping G1) and SKL as well (the internal workaround database claims that it does for all steppings, while the BSpec workaround table only mentions pre-production steppings), but the DRM doesn't do anything beyond whitelisting the L3SQCREG4 register so userspace can enable it when it sees fit. Do the same on KBL platforms. Improves performance of the GFXBench4 gl_manhattan31 benchmark by 60%, and gl_4 (AKA car chase) by 14% on a KBL GT2 running Mesa master -- This is followed by a regression of 35% and 10% respectively for the same benchmarks and platform caused by my recent patch series switching userspace to use the dataport constant cache instead of the sampler to implement uniform pull constant loads, which caused us to hit more heavily the L3 cache (and on platforms other than KBL had the opposite effect of improving performance of the same two benchmarks). The overall effect on KBL of this change combined with the recent userspace change is respectively 4.6% and 2.6%. SynMark2 OglShMapPcf was affected by the constant cache changes (though it improved as it did on other platforms rather than regressing), but is not significantly affected by this patch (with statistical significance of 5% and sample size 20). v2: Drop some more code to avoid unused variable warning.

Commit e5bbf30733f9 ("mmc: sdhci-acpi: Ensure connected devices are powered when probing") introduced code to powerup any acpi child nodes listed in the dstd. But some dstd-s list all possible devices used on some board variants, while reporting if the device is actually present and enabled in the status field of the device. So we end up calling the acpi _PS0 (power-on) method for devices which are not actually present. This does not always end well, e.g. on my cube iwork8 air tablet, this results in freezing the entire tablet as soon as the r8723bs module is loaded.

2017-01-12drm/i915/guc: Make sure vma containing firmware is GuC mappableMichał Winiarski1-1/+2
Since commit 4741da925fa3 ("drm/i915/guc: Assert that all GGTT offsets used by the GuC are mappable"), we're asserting that GuC firmware is in the GuC mappable range. Except we're not pinning the object with bias, which means it's possible to trigger this assert. Let's add a proper bias.

2017-01-12drm/cma-helper: Stop using drm_framebuffer_unregister_privateDaniel Vetter1-6/+3
This is the deprecated function for when you embedded the framebuffer somewhere else (which breaks refcounting). But cma helpers are using drm_framebuffer_remove and a free-standing fb, so this is rendundant.
