It handles firmware loading and manages client pool and doorbells. Firmware versioning: The firmware build process will generate a version header file with major and minor version defined. The versions are built into CSS header of firmware.
The firmware installation package will install symbolic link proper version of firmware. Currently this top address is K. Firmware log: Firmware log is enabled by setting i This context descriptor is allocated from a pool of entries. Kernel driver will allocate doorbell and workqueue for it. So the client can write Work Item then ring the doorbell. To simplify the implementation, we allocate one gem object that contains all pages for doorbell, process descriptor and workqueue.
It then triggers an interrupt on the GuC via another register write 0xC4C8. The kernel driver polls waiting for this update and then proceeds.
Doorbells: Doorbells are interrupts to uKernel. A doorbell is a single cache line QW mapped into process space. Work Items: There are several types of work items that the host may place into a workqueue, each with its own requirements and limitations.
The firmware may or may not have modulus key and exponent data. The header, uCode and RSA signature are must-have components that will be used by driver. Length of each components, which is all in dwords, can be found in header.
In the case that modulus and exponent are not present in fw, a. Header, uCode and RSA are must-have components. All firmware components, if they present, are in the sequence illustrated in the layout table above. Length info of each component can be found in header, in dwords. Modulus and exponent key are not required by driver. They may not appear in fw. So driver will load a truncated firmware in this case. GuC-specific firmware loader. GuC-based command submission. GuC Firmware Layout.Since Intel provides and supports open source drivers, Intel graphics are essentially plug-and-play.
Install the mesa package, which provides the DRI driver for 3D acceleration.
Also see Hardware video acceleration. For Skylake and newer processors, some video features e. For those processors it is necessary to add i This article or section is out of date. You can verify both are enabled by using dmesg :. There may be no need for any configuration to run Xorg. However, if Xorg does not start, and to take advantage of some driver options, you can create an Xorg configuration file similar to the one below:.
Additional options are added by the user on new lines below Driver. For the full list of options, see the intel 4 man page. If you experience issues with default SNA e. See intel 4 under Option "AccelMethod". The i kernel module allows for configuration via module options. Some of the module options impact power saving. A list of all options along with short descriptions and default values can be generated with the following command:. You will note that many options default to -1, resulting in per-chip powersaving defaults.
It is however possible to configure more aggressive powersaving by using module options. Making use of Framebuffer compression FBC can reduce power consumption while reducing memory bandwidth needed for screen refreshes. To enable FBC, use i The goal of Intel Fastboot is to preserve the frame-buffer as setup by the BIOS or bootloader to avoid any flickering until Xorg has started .
To enable fastboot, set i The H. Note however that this support is experimental and its development has been abandoned. Tests using mplayer showed that using vaapi to play back an H. Setting the preallocated video ram size higher in bios results in much better hardware decoded playback. Even p h works well if this is done. As of Mesa In Mesa Certain applications run faster with it. This setting does not affect Vulkan applications.
The SNA acceleration method causes tearing on some machines. To fix this, enable the "TearFree" option in the driver by adding the following line to your configuration file :. See the original bug report for more info. The intel-driver uses Triple Buffering for vertical synchronization, this allows for full performance and avoids tearing. To turn vertical synchronization off e. On some systems this can cause issues such as this.
To switch back to DRI2 add the following line to your configuration file :. For the modesetting driver, this method of disabling DRI3 does not work.
Should you experience missing font glyphs in GTK applications, the following workaround might help.To choose the right driver, first detect the graphics card. A full list of Intel CPU graphic capabilities can be found here. Otherwise errors such as the following might be visible in dmesg :. For Gen9 and Gen9. The legacy fbdev support is required since kernel 3. Since kernel version 4.
After making any make. Those wishing to not accept the Intel graphic driver defaults in the main repository can read on into the sub-sections below.
Before proceeding with the Intel DDX drivernote that this driver has been slowly deprecating for several years. This has caused other major   Linux distributions to begin to move toward the modesetting DDX driver detailed in the section below. Although presently faster than modesetting driverthere has been no official package release from Intel upstream for their DDX driver for quite some time and is therefore causing a maintenance burden on Gentoo's X11 package maintainers.
With this being stated, the Intel DDX driver has slight speed advantages over the generic modesetting driver as it is able to more closely interact with hardware acceleration present in chips utilizing SNA and DRI3.
As mentioned above, the modesetting DDX driver is now the default driver on newer Intel graphics chipsets for Gentoo. No additional steps or configuration are necessary. If it's necessary to force Xorg to load the modesetting driver the following config snippet can be used:. Note, if both intel. As of November 15th,  Vulkan is supported in the main ebuild repository for Intel Core processors using the i mesa driver.
Please note, that this will build a working Vulkan driver, but it will not provide a libvulkan. All provided commands can be discovered by listing the provided files with equery :. The i kernel driver includes the ability reduce flickering caused by modesetting operations during boot time. It does so by avoiding unnecessary modesetting operations when they are not needed . For CPUs older than Skylake, fastboot can be enabled by passing the i This can either be set using the built-in kernel command-line or via a bootloader's kernel options.
If the acl USE flag is enabled globally and ConsoleKit is being used default for desktop profiles permissions to video cards will be handled automatically. It is possible to check the permissions using getfacl :. A broader solution is to add the user s needing access the video card to the video group:.
Note that users will be able to run X without permission to the DRI subsystem, but acceleration will be disabled. The X server is designed to work out-of-the-box, with no need to manually edit X. Org's configuration files. It should detect and configure devices such as displays, keyboards, and mice. However, the main configuration file of the X server is the xorg. Related upstream bug report.
QT Quick Animation seem to loop too fast when vsync is not managed by the driver Reference. See also this Linux Mint tutorial. First, make sure vendor compatibility is on in the kernel configuration. Toshiba for Toshiba, etc. If it is, or when the brightness buttons are working, the issue is that the kernel can not detect where the brightness control is located.
Do your key bindings map to actions viewable in xev?Just over one week ago Intel released the Media Driver They have also now released their adjoining Media SDK KDE developers have been busy not only putting the finishing touches on the soon to be released Plasma 5.
As we approach the end of the year this driver still hasn't been mainlined yet but a new revision was sent out on Friday. Adding to the growing list of Mesa Following yesterday's release of Wine 5. Just a friendly reminder and last call that if you wanted to partake in this week's "Oktoberfest" Phoronix Premium special, it is ending this weekend.
Wine 5. After being in development for more than one year, it looks like with Linux 5. Of the many new features in Linux 5. Given many of the same workloads were negatively impacted by the CPU security mitigations of recent years, here is a look at the current mitigated vs.
While not merged yet, on Friday the latest version was sent out for review. Not only is the Plasma 5. Since the end of there have been Linux patches surfacing for bringing up the DSA support and now as we roll into the Linux kernel looks to begin making use of the new capabilities.
It's finally Zen 3 launch day! It's a virtual event given the ongoing pandemic, but this much anticipated CPU launch is now streaming. Today perhaps will be the most interesting day since the start of the pandemic With this quarter's Mesa Tencent developers have proposed "DMEMFS" as a virtual file-system with the intent of helping to save system memory on large servers such as in public cloud environments.
It looks like for Linux 5. Launched at the start of the year was the Kubuntu Focus as a polished KDE laptop while now it's been succeeded by a second-generation model. While GIMP 3. Out today is GIMP 2. DXVK 1. Ready to move past the tumultuous year that isIntel's open-source developers responsible for the OpenVINO toolkit today issued version Last month marked the release of the While the feature-packed OpenZFS 2.
It looks like the upcoming Linux 5. The raw performance and even performance-per-dollar is staggering out of the GeForce RTX with the initial tests carried out on Ubuntu Linux.
Linux gaming benchmarks will be out in the days ahead but for now is a look at the RTX compute performance across dozens of benchmarks and going as far back as the GeForce GTX series for comparison. Even with the tumultuous year due to the coronavirus pandemic, The Qt Company is still on track for delivering the Qt 6.
All rights reserved.This excludes a set of SoC platforms with an SGX rendering unit, those have basic support through the gma drm driver. This section covers core driver infrastructure used by both the display and the GEM parts of the driver. The i driver supports dynamic enabling and disabling of entire hardware blocks at runtime. This is especially important on the display side where software is supposed to control many power gates manually on recent hardware, since on the GT side a lot of the power management is done by the hardware.
But even there some manual control at the device level is required. This file provides generic functions to the driver for grabbing and releasing references for abstract power domains.
It then maps those to the actual power wells present for a given platform. This function can be used to check the hw power domain state. It is mostly used in hardware state readout functions. Everywhere else code should rely upon explicit power domain reference counting to ensure that the hardware block is powered up before accessing it.
This functions controls the state of this little hack. While the initial power domain state is enabled runtime pm is effectively disabled. This function grabs a power domain reference for domain and ensures that the power domain and all its parents are powered up. Therefore users should only grab a reference to the innermost power domain they need. This function also disables runtime pm and ensures that the device stays powered up so that the driver can be reloaded.
This function prepares the hardware power domain state before entering system suspend. This function grabs a device-level runtime pm reference if the device is already in use and ensures that it is powered up.
Therefore it is only valid to call this functions from contexts where the device is known to be powered up and where trying to power it up would result in hilarity and deadlocks. Note that this function does currently not enable runtime pm for the subordinate display power domains.
Normal register access will handle the forcewake domains automatically. However if some sequence requires the GT to not power down a particular forcewake domains this function should be called at the beginning of the sequence. It is responsibility of the caller to handle the difference between asking full domain reset versus reset for all available individual engines.Opposition View: Everton Morgan Looks Forward To Everton Clash First Team Training: Everton The Foxes secured a useful 2-1 win against Swansea City last weekend and followed that with a 3-1 victory over Leeds United to seal their place in the Carabao Cup quarter-finals.

This week, the USGA have made the decision to revert to a traditional US Open venue after a few years of breaking the mould. In 2013, they returned to the logistically challenging Merion Golf Club (after a 32 year absence) while in 2015, it was the brand-new venue of Chambers Bay.
The total yardage will vary over the four days with a maximum length of 7,900 yards - a daunting number at first glance.
Only designed in 2006, the course is a bit of an unknown entity having yet to host a PGA Tour event, though it did stage the 2011 US Amateur. Mike Davis, Executive Director of the USGA, is the man in charge of setting up US Open courses and below is his summary of Erin Hills and what unique properties we should be looking out for.
The Wisconsin course is a windswept property which provides a firm playing surface that plays shorter than its length on the scorecard. The one area in which the bombers will have an advantage, is the four par 5s, which all measure over 600 yards and offer the best opportunity for scoring. It is worth keeping an eye on the weather as Mother Nature will no doubt have a role to play this week, as the wind can blow from any direction.
As a result, the fairways are generous in width, especially compared to normal US Open tracks like Oakmont, Pebble Beach and Winged Foot. However, the wind is not its only defence with contoured fairways making for very few flat lies and several semi-blind and blind shots. These bunkers surround many of the greens, along with shaved run-off areas.
Rather than seeing players chipping out of thick rough if they miss the dance floor, they will instead be left with a choice of putting, playing a bump and run or pitching.
The only US Open course in recent memory that was reminiscent of this was Pinehurst no. They will be slick surfaces that run true with many raised or multi-tiered.
In summary, superior ball-striking skills will be rewarded this week, particularly for those who drive the ball well from the tee. Shot-making ability, playing well in the wind and liking firm surfaces are all a plus and an imaginative short-game will be crucial. Being long certainly looks to be an advantage but not essential, although Driving Distance stats will be far more important than Driving Accuracy over the week.
Big hitters often taste success on US Open tracks, with eight of the last 11 winners ranking in the top-eight for DD during the week of their success.
A high Greens in Regulation percentage will be key and is usually the case year-in year-out at this major.As we know, we can bet on a single event or combine a certain number of outcomes, which is.
