* Use separate descriptors in bhyve's stdio uart backend.Mark Johnston2019-04-221-61/+71
| | | | | | | | | | | | | | | | | | | | | bhyve was previously using stdin for both reading and writing to the console, which made it difficult to redirect console output. Use stdin for reading and stdout for writing. This makes it easier to use bhyve as a backend for syzkaller. As a side effect, the change fixes a minor bug which would cause bhyve to fail with ENOTCAPABLE if configured to use nmdm for com1 and stdio for com2. bhyveload already uses separate descriptors, as does the bvmcons driver.

* Use a shadow buffer and never read from the frame buffer. Remove large slowBruce Evans2019-04-215-314/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | code for reading from the frame buffer. Reading from the frame buffer is usually much slower than writing to the frame buffer. Typically 10 to 100 times slower. It old modes, it takes many more PIOs, and in newer modes with no PIOs writes are often write-combined while reads remain uncached. Reading from the frame buffer is not very common, so this change doesn't give speedups of 10 to 100 times. My main test case is a floodfill() function that reads about as many pixels as it writes. The speedups are typically a factor of 2 to 4. Duplicating writes to the shadow buffer is slower when no reads from the frame buffer are done, but reads are often done for the pixels under the mouse cursor, and doing these reads from the shadow buffer more than compensates for the overhead of writing the shadow buffer in at least the slower modes. Management of the mouse cursor also becomes simpler. The shadow buffer doesn't take any extra memory, except twice as much in old 4-plane modes. A buffer for holding a copy of the frame buffer was allocated up front for use in the screen switching signal handler. This wasn't changed when the handler was made async-signal safe. Use the same buffer the shadow (but make it twice as large in the 4-plane modes), and remove large special code for writing it as well as large special code for reading ut. It used to have a rawer format in the 4-plane modes. Now it has a bitmap format which takes twice as much memory but can be written almost as fast without special code. VIDBUFs that are not the whole frame buffer were never supported, and the change depends on this. Check for invalid VIDBUFs in some places and do nothing. The removed code did something not so good.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | resetting ANI. One of the fun issues with scanning has been how the existing ANI values were programmed into the hardware when channels were changed. If you're on a really crappy channel and ANI has made you deaf then when you scan you continue to be deaf on all channels. This code passes in a flag to startpcureceive which in AR5416 and later is also used to enable ANI. This allows it to know if it's a normal operation or a scan operation. This fixes my situation at home where a temporary spot of a device going deaf due to interference starts scanning and .. can't hear anything until I restart. Now, this isn't the full fix - ideally: (a) all the ANI config and per-channel information would be migrated to the shared HAL stuff and enabled for all of the NICs; (b) when a station reassociates and some other error conditions (like missed beacons, NF calibration failures, etc) a knob to reset ANI parameters would likely help recovery.

This turns off useless palette management in direct modes. Palette management had no useful effect since the hardware palette is not used in these modes. This transiently acquires i/o privilege if possible as needed to give VGLSetBorder() and VGLBlankDisplay() a chance of working. Neither has much chance of working. I was going to drop support for them in direct modes, but found that VGLBlankDisplay() still works with an old graphics card on a not so old LCD monitor. This has some good side effects: reduce glitches for managing the palette for screen switches, and speed up and reduce async-signal-unsafeness in mouse cursor drawing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jobs using the @<second> syntax currently only get executed if they exist when cron is started. The simplest reproducer of this is: echo '@20 root echo "Hello!"' >> /etc/cron.d/myjob myjob will get loaded at the next second==0, but this echo job will not run until cron restarts. These jobs are normally handled in run_reboot_jobs(), which sets e->lastexit of INTERVAL jobs to the startup time so they run 'n' seconds later. Fix this by special-casing TargetTime > 0 in the database load. Preexisting jobs will be handled at startup during run_reboot_jobs as normal, but if we've reloaded a database during runtime we'll hit this case and set e->lastexit to the current time when we process it. They will then run every 'n' seconds from that point, and a full restart of cron is no longer required to make these jobs work.
