...here really thinks it needs to remain in the tree? Can we hold on a tiny bit so that I can verify we haven't regressed crosvm all the way into mainline? Daniel, is there any chance you could test with kvmtool as well on your setup? You can easily compile it as a static binary and run it from ChromeOS with: lkvm-static run -c 1 -p "earlycon=uart,mmio,0x3f8" -l Image which should start a UP guest and drop you to a shell. In the meantime, I'm starting to build crosvm on my kevin running mainline. Thanks, M. -- Jazz is not dead, it just smell funny.

...s to be provided directly instead of being probed using the BIOS (which Tegra does not have). The last patch adds the GK20A clock device. Arguably the clock can be seen as a stripped-down version of what is seen on NVE0, however instead of using NVE0 support has been written from scratch using the ChromeOS kernel as a basis. There are several reasons for this: - The ChromeOS driver uses a lookup table for the P coefficient which I could not find in the NVE0 driver, - Some registers that NVE0 expects to find are not present on GK20A (e.g. 0x137120 and 0x137140), - Calculation of MNP is done diff...

Here it is: <snip> I am a recent addition to Google's ChromeOS gfx team. I am currently working on display testing and reporting. An important part of this is our screen capture tool, which works by querying drm for crtcs, planes, and fbs. Unfortunately, there is only limited information available via drmModeGetFB(), which often wrong information when dr...

We are trying to enable large file support for everything built for ARM on ChromeOS and openssh uses mkstemp which has a 64-bit version for compatibility with open64. When looking into enabling the large file support flags, I noticed: `void start_progress_meter(const char *, off_t, off_t *);` in progressmeter.h which would have different ABIs with and without large file supp...

Hello, I have heard that Chrome OS is Linux based, so I am wondering if there is anyway to use R on a Google Chromebook using one of your Linux packages. If not, do you plan on making a version of R that is compatible with chromebooks or cloud based? [[alternative HTML version deleted]]

Chrome OS will soon be adding the chrome.fileSystemProvider[1] API, which would enable the development of a Samba Chrome OS app when used in conjunction with the chrome.sockets.* API or the networking APIs provided by NaCl. Is anyone on this list interested in porting or integrating Samba with Chrome OS? If so, there are two routes we can take: a full JavaScript port, or porting an existing C++
