We do not need to set the CS (Command Stop) bit in the Command Ring Control Register. CS is implied by CA (Command Abort). I'm not sure if there is a defined execution order for these command bits, so it's safer to only use the CA bit as it includes the CS function.

This fixes issues with how we handle events generated by the xHCI "command abort" command. first, depending on the state of the xHCI controller, the COMMAND_ABORTED may not be generated. If the controller was between commands, only the COMMAND_RING_STOPPED event will be generated. Second, do not adjust the command ring "cur" pointer as that just confuses the controller.

2020-08-28libpayload: cbgfx: Support buffered I/OHung-Te Lin
For payloads with UI based on CBGFX, they usually start by calling clear_canvas or clear_screen and then draw the UI elements. However, that makes the screen flicker. A typical solution is to identify and minimize the area to redraw. However for payloads with complicated UI and do not care about latency, an alternative is to enable buffered I/O. The new enable_graphics_buffer() will redirect all graphics I/O into an invisible working buffer. To flush (redraw) the buffer to the real screen, call flush_graphics_buffer(). To stop buffering, call disable_graphics_buffer(). BUG=None TEST=Add the enable, flush and disable calls to payload 'depthcharge', built a firmware and boots into Chrome OS recover UI. No more flickering. The average rendering time on x86 platform is 1.2ms.

2020-08-24libpayload: Cache copy of `cb_framebuffer` structNico Huber
Our AArch64 code supports dynamic framebuffer allocation which makes it necessary to change the framebuffer information during runtime. Having a pointer inside `libsysinfo` made a mess of it as the pointer would either refer to the original struct inside the coreboot table or to a new struct inside payload space. The latter would be unaffected by a relocation of the payload. Instead of the pointer, we'll always keep a copy of the whole struct, which can be altered on demand without affecting the coreboot table. To align the `video/graphics` driver with the console driver, we also replace `fbaddr` with a macro `FB` that calls phys_to_virt().

2020-08-24libpayload: Cache physical cbmem console addressNico Huber
Same as with other consoles and drivers that cache an address outside the payload (e.g. video/corebootfb), we should store the physical address, so we can derive the virtual address on demand. This makes it save to use the address across relocations. As a first step in migrating `libsysinfo` to `uintptr_t`, we also switch to the physical address there. Fixes the default build of FILO, tested with Qemu/i440FX and Qemu/Q35.

2020-07-23libpayload: cbgfx: Add draw_line()Yu-Ping Wu
Add a function draw_line() to draw either a horizontal or vertical line segment. Theoretically a horizontal line can also be drawn by calling draw_rounded_box() with dim_rel.x being the line length and dim_rel.y being the line width. However, due to the truncation in integer division when converting relative coordinates to absolute ones, this will potentially produce inconsistent line widths, depending on the value of pos_rel.y. It is guaranteed that draw_line() will produce consistent line widths, regardless of the position of the line. Also, when the thickness argument is zero, this function is able to draw a line with 1-pixel width, which is not achievable by draw_rounded_box().

2020-07-09libpayload: cbgfx: Replace bilinear resampling with LanczosJulius Werner
This patch improves the image resampling (scaling) code in CBGFX to use the Lanczos algorithm that is widely considered the "best" resampling algorithm (e.g. also the first choice in Python's PIL library). It is of course much more elaborate and therefore slower than bilinear resampling, but a lot of the difference can be made up with optimizations, and the resulting code was found to still produce acceptable speeds for existing Chrome OS UI use cases (on an Arm Cortex-A55 device, time to scale an image to 1101x593 went from ~88ms to ~275ms, a little over 3x slowdown). Nevertheless, if this should be too slow for anyone there's also an option to tune it down a little, but still much better than bilinear (same operation was ~170ms with this).

2020-07-06libpayload: cbgfx: Fix add_fractions() overflow reductionJulius Werner
log2(1) is 0 and log2(0) is -1. If we have the int64_t 0xffffffff then log2(0xffffffff >> 31) = log2(0x1) = 0, so the current reduction code would not shift. That's a bad idea, though, since 0xffffffff when interpreted as an int32_t would become a negative number. We need to always shift one more than the current code does to get a safe reduction. This also means we can get rid of another compare/branch since -1 is the smallest result log2() can return, so the shift can no longer go negative now.

2020-05-01lp/drivers/usb: Add quirk for QEMU XHCI root hubDuncan Laurie
The QEMU XHCI driver does not implement the Port Change Detect bit in the USBSTS register. As a result no devices are attached without looking at each port individually. Detect this as a quirk based on the QEMU XHCI controller PCI ID, and apply it to the root hub quirk list so it can get used by the generic hub driver to skip this check. With this change an attached USB mass storage device is detected and able to boot when supplied to qemu: -drive if=none,id=usbmsc,format=raw,file=/tmp/disk.img -device qemu-xhci,id-xhci -device usb-storage,bus=xhci.0,drive=usbmsc Change-Id: I6689cb1dbb24c93d45f5c5ef040b713925d07588 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/39839 Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Nico Huber <nico.h@gmx.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2020-04-30libpayload: xhci: Do not memcpy registersJulius Werner
memcpy() is meant to be used on normal memory and often implemented with architecture-specific optimizations to make that as performant as possible. MMIO registers often have special access restrictions that may be incompatible with whatever memcpy() does. For example, on arm64 it uses the LDP (load pair) to load 16 bytes at a time, which makes 4-byte MMIO registers unhappy. This patch removes the caching of the XHCI capreg registers and changes it back to a pointer. The CAP_GET() macro is still accessing a full (non-bitfield) uint32_t at the end so this should still generate a 4-byte access (which was the goal of the original change in CB:39838).

2020-04-20libpayload: Make 8250 UART driver relocation safeNico Huber
`lib_sysinfo->serial` is a virtual pointer into coreboot tables. It's not valid across relocation. Accessing the wrong value during relocation of FILO resulted in a hang with DEBUG_SEGMENT and UART console enabled. Work around that by caching the whole table entry locally. An alternative would be to revise `sysinfo`, to contain no virtual pointers to anything outside the payload.

2019-09-18libpayload: Use interrupt transfers for USB hubsNico Huber
In interactive payloads, the USB stack's poll procedure is implicitly called from the UI loop. Since all USB control transfers are handled synchronously, polling hubs with these slows the UI significantly down. So switch to interrupt transfers that are done asynchronously and only perform control transfers when the hub reported a status change. We use the interrupt endpoint's max packet size instead of the theo- retical transfer length of `(bNrPorts + 1) / 8` as Linux' code mentions hubs that return too much data.

2019-08-22libpayload: usbmsc: Factor out usb_msc_force_init() functionJulius Werner
We're planning to have a use case with a custom USB device that implements the USB mass storage protocol on its bulk endpoints, but does not have the normal MSC class/protocol interface descriptors and does not support class-specific control requests (Get Max LUN and Bulk-Only Reset). We'd like to identify/enumerate the device via usb_generic_create() in our payload but then reuse all the normal MSC driver code. In order to make that possible, this patch factors a new usb_msc_force_init() function out of usb_msc_init() which will initialize an MSC device without checking its descriptors. It also adds some "quirks" flags that allow devices registered this way to customize behavior of the MSC stack.

2019-08-22libpayload: usbmsc: Skip zero-length packets at end of dataJulius Werner
Some broken USB mass storage devices send another zero-length packet at the end of the data part of a transfer if the amount of data was evenly divisible by the packet size (which is pretty much always the case for block reads). This packet will get interpreted as the CSW and screw up the MSC state machine. This patch works around this issue by retrying the CSW transfer when it was received as exactly 0 bytes. This is the same mitigation the Linux kernel uses and harmless for correctly behaving devices. Also tighten validation of the CSW a little, making sure we verify the length before we read any fields and checking the signature in addition to the tag.

2019-06-06Revert "libpayload: Reset PS/2 keyboard"Nico Huber
Documentation is scarce on the matter, however the related coreboot code suggests that after the ACK, the keyboard also sends the result of the self test (passed/failed). It looks like this result is never consumed here, probably resulting in further confusion for later com- mands. Let's revert this for now (if it's not too late for the 4.10 release) and break things later again. IMHO, due to the fact that there are dozens of different keyboard controller and keyboard implementations and no accurate specification followed, such changes should be tested on a lot of hardware before merge. This reverts commit a99ed13e3397bc536012120aab8cadb827913863. This reverts commit 7ae606f57f0b3d450ae748141b0e2367041b27d3.

Loading a libpayload based payload like coreinfo or FILO from SeaBIOS or GRUB pressing keys does not give the expected results. For example, pressing F1 gives the character 24 translated to scan code 6a. ESC for example 43 (111) in coreinfo loaded from SeaBIOS on QEMU Q35. The problem is not reproducible using the payload directly, that means without SeaBIOS or GRUB. The problem seems to be, that those have already initialized the PS/2 controller and AT keyboard. Comparing it with coreboot’s PS/2 keyboard code, the keyboard needs to be reset. That seems to fix the issue, when the keyboard was initialized before. TEST=Build coreboot for QEMU Q35 with SeaBIOS, and coreinfo as secondary payload. Run qemu-system-i386 -M q35 -L /dev/shm -bios build/coreboot.rom -serial stdio press 3 to select the coreinfo payload, and verify that the keys F1 and F2 are working.
