2016-07-27Remove a feature to re-use existing early bootstrap mappings. ThisPatrick Wildt
allowed you to pass a virtual address, which you received from an early bootstrap mapping, as physical address to bus_space_map(9). It breaks bus_space_map(9) for peripherals that are after 0xC0000000, as it assumes that everything after that address cannot be a real peripheral. But that's wrong. It does not make sense to pass a virtual address to bus_space_map(9) anyway, so just get rid of this whole "feature". ok kettenis@

2016-07-27When pmap_page_remove() is called by UVM, a physical page is to bePatrick Wildt
removed from pmaps it currently is in. To check if a virtual address pointing to that physical page has been mapped, the code uses the l2pte_valid() function. Unfortunately there is a difference between being valid and the PTE being zero. If a page is mapped but has never been accessed, it will be non-zero but invalid. In that case the PTE for that virtual address will not be zeroed and the virtual address will be removed from the vm page struct. The next time someone tries to map a page to that virtual address, other pmap code will consider the virtual address to be already mapped, even though that assumption is completely wrong. To make sure this does not happen, check the PTE for zero. This way the PTE will be zeroed correctly. The check for zero is how other ARM pmap code also handles this issue. ok kettenis@ tom@

2016-07-27Instead of passing the raw reg property to simplebus nodes,Patrick Wildt
pass a pre-processed array of fdt_reg structs. This means that the drivers don't have to understand the cell properties themselves but can rely on the 64-bit addr/size pairs. ok kettenis@

2016-07-26In rsu(4), put code that twiddles HT data in the ic under #ifdef notyet.Stefan Sperling
Some code paths in this driver peek at ic_htcaps and act upon it, so let's play it safe until this driver gets its 11n support enabled on purpose. Spotted while investigating the bug fixed in r1.35.
2016-07-26Remove the restriction that the kernel needs to be loaded at the bottom ofMark Kettenis
physical memory. This makes it possible to boot OpenBSD on platforms that have physical memory start at address 0x00000000 as the EFI bootloader will only attempt to load kernels at address 0x10000000 and above to work around a bug in the u-boot EFI API layer. ok patrick@

2016-07-23Previously the uarts attached in order, so that the first attached uartPatrick Wildt
is always the serial console. With device tree enumeration, this order is not given anymore. The serial console might now attach with a different minor and has to be updated, otherwise there will be no further output on the serial. Thus, re-create the i.MX6 console with the correct minor number on attach. ok jsg@, kettenis@

2016-07-23The linux kernel treated the "phy-reset-gpio" as active-low regardless of whatMark Kettenis
the device tree says. As a result many device trees encode it as active-high when active-low is needed. For now just override the device tree. ok jsg@, patrick@
2016-07-23Fix a few CPUID emulation issues:Mike Larkin
Don't advertise a hyperthreaded CPU. This doesn't make a lot of sense now as we only provide UP guest support. This, combined with the other CPUID issues fixed, fooled NetBSD's topology enumeration code into thinking we had an unsupportable core/thread/package configuration. Also fixed the unsupported CPUID functions by returning 0 in the return registers instead of leaving whatever trash happened to be there before the call was made.
2016-07-23Dump vcpu state on unknown exit type, and add a diagnostic messageMike Larkin
(including vcpu state dump) on failure to enter due to an incorrect guest state. Added as a debug facility when diagnosing interruptibility state problems seen while testing NetBSD guest VMs.
2016-07-23Ensure some undesirable entry controls are cleared, instead of relyingMike Larkin
on the default settings. Noticed when booting a NetBSD guest VM.

2016-07-22Fallback to the known fec irq number on imx.6 if the fdtJonathan Gray
interrupts-extended property is missing or not the size we expect. Some dtbs implement a workaround for "ERR006687 ENET: Only the ENET wake-up interrupt request can wake the system from Wait mode" suggested by the IMX6DQCE errata document to set an undocumented gpio mux mode and handle the interrupt via gpio. We don't support gpio interrupts yet, hopefully this change is enough to make interrupts work on wandboard and sabre lite again till we do. Discussed with kettenis and patrick, tested on sabre lite by patrick.

2016-07-20In net80211, enable RTS for frames above a particular size (currently 512Stefan Sperling
bytes). This is what other OS have been doing for years. In our stack this feature was present but disabled at compile-time by an #ifdef. This is a low risk change because drivers were already required to use RTS whenever the AP set the USE_PROTECTION flag in ERP elements of its beacons. This change allows for reasonable throughput on loaded 11g networks whereas before they were practically unusable. tests and ok phessler@
2016-07-20Bring iwn_update_htprot() back, so iwn(4) will properly keep trackStefan Sperling
of HT protection changes while associated. HT protection affects behaviour on Tx but is configured along with Rx settings (because Intel likes it that way). And our previous iwn_update_htprot() implementation had a bug where it would accidentally clear bits which enable CCK rates for Rx. The Intel Wireless-N 2200 chip accordingly stopped receiving some frames (most notably broadcast frames) and the link broke down. Also, restore the power-saving level after updating the Rx config (like Linux does), and add some DELAYs for good measure to ensure the firmware has time to process asynchronous commands we send. tested by myself and mlarkin@ ok mlarkin@
