2020-09-03amd64: lapic: refactor timer programmingcheloha
We reprogram the lapic timer by hand in three separate places. This is error-prone and difficult to read. To clean things up, introduce routines for reprogramming the lapic timer in a given mode. lapic_timer_oneshot() starts a oneshot countdown. lapic_timer_periodic() starts a repeating countdown. Both of these routines call lapic_timer_start(), wherein we actually write the lapic registers. With input from dlg@. Earlier version eyeballed by mlarkin@. Suspend/resume tested by gnezdo@.
2020-09-03Sprinkle some more eieio(); seems to avoid triggering the KASSERT(new > old).Mark Kettenis
2020-09-03The "USL" VT switch and keyboard ioctls are a hack and don't follow theMark Kettenis
proper BSD way where the third argument is always a pointer and data is transferred between userland and kernel using copyin(9) and copyout(9). Intead an int is encoded in the thirs argument. This works on 32-bit architectures and little-endian 64-bit architectures. But not on big-endian 64-bit architectures. Deal with this by handling the argument as long (which matches the size of a pointer). Hopefully we can eliminate these ioctls in the near future. ok deraadt@

2020-09-02Add #define SID_SCSI2_RESPONSE 0x2 to allow elimination of another bunch ofKenneth R Westerback
magic numbers. As the nearby comment says '< 2 is obsolete. >2 is reserved'. So 0x2 is just right.

2020-08-30pppac(4) uses per cpu counters for collect `ifnet' statistics, but inmvs
pipex(4) layer this `ifnet' still uses `if_data'. Also pppx(4) doesn't use per cpu counters but `if_data'. Add per cpu counters to pppx(4) and pipex(4). This finishes interface statistics collecting mess. ok yasuoka@

handle the priority levels better and guarantee ordering of restoring the priority level after running an interrupt handler and checking for a new interrupt.
2020-08-30Lock all kernel PTE entries into the page tables, even "managed" onesMark Kettenis
entered by pmap_enter(9). Otherwise kernel stack pages get evicted and that doesn't end well. We probably only need to lock in wired pages and I will probably revisit this at some later stage. tested by deraadt@

2020-08-30PLL1(CPU_PLL) stability improvement for Allwinner H3/H2+SASANO Takayoshi
Due to unstable of PLL1, sometimes the system has hanged up especially at boot. This is observed at Allwinner H3/H2+ processor. To solve the problem, PLL1 setting procedure is same as Linux. 1. change clock source to 24MHz 2. wait 1usec (new) 3. disable PLL1 (new) 4. set new NKMP value, but M should be 1 5. re-enable PLL1 (new) 6. wait PLL1 stable (modified) 7. change clock source to PLL1 8. wait 1usec (new) Once disable PLL1 before setting NKMP is very important. And, sometimes LOCK flag is set even if PLL has not locked yet so wait for PLL is modified with simple delay() by the value of PLL_STABLE_TIME_REG1 register. Not only Allwinner H3/H2+ but also all (i.e. A64) Allwinner processors datasheet has "If the clock source is changed, at most to wait for 8 present running clock cycles." sentence at CPU clock source selection field of CPU/AXI configuration register. But this is ambiguous that _who_ should do _what_ during that cycles. It is unclear that changing clock source itself invoke PLL1 unstability. For safety, added 1usec wait after changing clock source like Linux. ok by kettenis@, thanks to adr at sdf dot org
2020-08-29More recent MMC specificiations add READ(12)/WRITE(12). So add cd_cmd_rw12()Kenneth R Westerback
and let cdstart() use it if the requested i/o is unable to fit into a READ(10). Certainly better than silently truncating the i/o into a READ(10)/WRITE(10).

2020-08-29Before clearing the kcov descriptor associated with a thread make sureanton
no other thread is currently within a remote section. Otherwise, the remote subsystem could end up in a broken state where it doesn't reset the necessary bits upon leaving the remote section. Therefore introduce the kr_barrier() routine which waits until all ongoing remote sections have been left. Also, extend the scope of the mutex to also cover fields of struct kcov_dev. This is necessary to ensure correctness. Reported-by: syzbot+64122a5f01be1b1abb96@syzkaller.appspotmail.com

something more generic. It will soon cover the whole kcov subsystem.
2020-08-29Have [cd|sd]_cmd_rw[6|10|12|16] return the length of the created command andKenneth R Westerback
have the caller assign it to xs->cmdlen. Pass in xs->cmd instead of xs. A slightly cleaner API that provides the potential of detecting and reacting to a failure to create the desired command.

favour of simply using the device's claimed SCSI level of support. Except of course for ATAPI/USB devices which often don't claim anything. Keep assuming they are at least SCSI-2. Use consistant tests in sdminphys/cdminphys/sdstart/cdstart.
