| | | | | | | | | | | | | When updating individual CPU's lowest Cx state to use, never set it to a state lower than the lowest one supported by the current CPU. This closes some races with changes to the hw.acpi.cpu_cx_lowest sysctl while Cx states for individual CPUs were changing (e.g. unplugging the AC adapter of a laptop) that could result in panics.

PR: kern/136251 (fixed differently than the submitted patch) r204158 | kmacy - make printf conditional - fix witness warnings by making configuration lock a mutex r207673 | joel Switch to our preferred 2-clause BSD license. Approved by: kmacy r208901 | ken A number of netfront fixes and stability improvements: - Re-enable TSO. This was broken previously due to CSUM_TSO clearing the CSUM_TCP flag, so our checksum flags were incorrectly set going to the netback driver. That was fixed in r206844 in tcp_output.c, so we can turn TSO back on here. - Fix the way transmit slots are calculated, so that we can't overfill the ring. - Avoid sending packets with more fragments/segments than netback can handle. The Linux netback code can only handle packets of MAX_SKB_FRAGS, which turns out to be 18 on machines with 4K pages. We can easily generate packets with 32 or so fragments with TSO turned on. Right now the solution is just to drop the packets (since netback doesn't seem to handle it gracefully), but we should come up with a way to allow a driver to tell the TCP stack the maximum number of fragments it can handle in a single packet. - Fix the way the consumer is tracked in the receive path. It could get out of sync fairly easily. - Use standard Xen ring macros to make it clearer how netfront is using the rings. - Get rid of Linux-ish negative errno return values. - Added more documentation to the driver. - Refactored code to make it easier to read. - Some other minor fixes.

| | | | | | | | | | | | | | | | | Program the K2 SATA controller's interrupt to be level-triggered low, and respect the edge/level settings in the device tree. OpenPIC on powerpc sets interrupts to be level high by default. On Apple interrupt controllers, all level interrupts are low regardless of programming except interrupt 0, used by K2 SATA on some Apple systems, with the result that the K2 SATA IRQ is misconfigured. Pending review of changes to this default, work around this by changing the programming of the K2 SATA interrupt to level low. Approved by: re (kib) Notes: svn path=/stable/8/; revision=209044

| | | | | | | | | | | | | | | | | Some revisions of the Serverworks K2 SATA controller have a data corruption bug where if an ATA command is issued before DMA is started, data will become available to the controller before it knows what to do with it. This results in either data corruption or a controller crash. This patch remedies the problem by adopting the workaround employed by Linux and Darwin: starting the DMA engine prior to sending the ATA command.

| | | | | | | | | | | | | | | | | | | | | | | | Fix a bug introduced in r199011. When bge(4) reuses loaded RX buffers it should also reinitialize RX descriptors otherwise some stale data could be passed to controller. This could end up with mbuf double free or unexpected NULL pointer dereference in upper stack. To fix the issue, save loaded buffer's length and reinitialize RX descriptors with the saved value whenever bge(4) reuses the loaded RX buffers. While I'm here, increase the number of RX buffers to 512 from 256. This simplifies RX buffer handling as well as giving more RX buffers. Controller supports just fixed number of RX buffers (i.e. 512) and bge(4) used to rely on hope that our CPU is fast enough to keep up with the controller. With this change, bge(4) will use 1MB for RX buffers but I don't think it would cause problems in these days.

| | | | | | | | | | | | | | | | | | | | | | | Add uep(4), driver for USB onscreen touch panel from eGalax. The driver is stub. It just creates device entry and feeds reassembled packets from hardware into it. If in future we would port wsmouse(4) from NetBSD, or make sysmouse(4) to support absolute motion events, then the driver can be extended to act as system mouse. Meanwhile, it just presents a /dev/uep0, that can be utilized by X driver, that I am going to commit to ports tree soon. The name for the driver is chosen to be the same as in NetBSD, however, due to different USB stacks this driver isn't a port. The driver is supported by ports/x11-drivers/xf86-input-egalax.

| | | | | | | | | | | | | | | | When configuring a system-wide couting PMC, hwpmc was incorrectly logging process mappings for that PMC. Nothing ever reads pmc logs out of a counting PMC, so the log buffers were leaked when the PMC was deconfigured. The process mappings are only useful for sampling PMCs anyway, so only log the mappings if the PMC is a sampling PMC. This bug would cause allocating sample-mode PMCs to fail with ENOMEM after allocating several counting-mode PMCs. Approved by: emaste (mentor) Notes: svn path=/stable/8/; revision=208517

| | | | | | | | | | | | | | | | | | | | | | If controller received bad frames make sure to update newly added RFA. Also drop frames that have either CRC error or alignment error. Normally bad frames are not received at all. But controllers running in promiscuous mode will receive bad frames. 82557 will also receive bad frames to receive VLAN oversized frames. While I'm here mark RNR condition if driver happen to see RNR in RFA status and restart RU to receive frames again. Because driver checks all received frames in RX loop, RNR condition could be set in the middle of RX processing. Just relying on RNR interrupt was not enough.
