[RESEND PATCH 00/16] Nokia RX-51: Fix USB TTY console and enable it

[Pali Rohár]

This series contain resensed patches from two patch series:
* Nokia RX-51: Fix USB TTY console and enable it
* usbtty/musb: Fix file transfers
They are rebased on top of master branch.

This patch series fix usbtty code (serial console via USB peripheral
mode), fix underlying musb peripheral code, fix compilation of
CONFIG_USB_DEVICE (used by usbtty), remove unused Nokia RX-51 code to
decrease size of U-Boot binary and finally enable usbtty serial console
for Nokia RX-51.

With this patch series debugging of Nokia RX-51 can be done also via USB
serial console.

It fixes also stability of musb code and allows usage of file transfers
via Kermit protocol on Nokia RX-51. Kermit file transfer via U-Boot loadb
command is stable on Nokia N900 and gives about 52kB/s transfer rate.

On computer this serial console is accessible via /dev/ttyACM0 device.

[RESEND PATCH 01/16] serial: usbtty: Fix puts function

[Pali Rohár]

This function has incorrect implementation of prepending CR prior LF.
Without this patch it prepended CR prior whole string which is going to be
written and let LF without leading CR. Fix this issue by inserting CR at
correct place to make output on usbtty serial console more readable.

[RESEND PATCH 02/16] serial: usbtty: Send urb data in correct order

[Pali Rohár]

Function next_urb() selects the last urb data buffer from linked list to
which next data from usbtty puts should be appended.

But to check if TX data still exists it is needed to look at the first urb
data buffer from linked list. So check for endpoint->tx_urb (first from the
linked list) instead of current_urb (the last from the linked list).

Successful call to udc_endpoint_write() may invalidate active urb and
allocate new in queue which invalidate pointer returned by next_urb()
function.

So call next_urb() prior putting data into urb buffer and call it every
time after using udc_endpoint_write() function to prevent sending data from
usbtty puts in incorrect order.

This patch fixes issue that usbtty code does not transmit data when they
are waiting in the tx queue.

[RESEND PATCH 03/16] usb: musb: Fix compilation of gadget code

[Pali Rohár]

musb udc code depends on usb gadget code provided by CONFIG_USB_DEVICE and
defined in drivers/usb/gadget/Makefile. But this Makefile is not included
into U-Boot build when CONFIG_USB_GADGET is not set. As CONFIG_USB_DEVICE
cannot be enabled together with CONFIG_USB_GADGET it means that dependency
for musb udc code is not compiled during build. Fix it by including
drivers/usb/gadget dependency also when CONFIG_USB_DEVICE is set.

This patch fixes compile errors:

[RESEND PATCH 04/16] usb: musb: Always clear the data toggle bit when configuring ep

[Pali Rohár]

Without this patch it was done only when U-Boot was compiled with MUSB Host
Controller. But it is needed also for MUSB Device Controller, otherwise
Device Controller does not work.

[RESEND PATCH 05/16] usb: musb: Fix configuring FIFO for endpoints

[Pali Rohár]

This patch fixes configuring FIFO for one-directional endpoints which have
either RX or TX queue and therefore only one FIFO.

Size of FIFO buffer is 2^(idx+3) bytes and starting address is 2^(addr+3).
Moreover first 64 bytes are reserved for EP0.

Without this patch if FIFO size specified by caller was zero then idx was
incorrectly calculated (expr. ffs(0)-1) and size overflowed in fifosz
register. This register uses has only 4 bits for FIFO size. Moreover
specifying zero size is not possible.

This patch is fixing calculation of start address and buffer size to
minimal value and ensure that it would not overlap with reserved EP0
buffer.

This issue caused loose of packets on USB bus in both directions and
basically usbtty was unusable.

Changes in v2:
* Correctly calculate minimal buffer size
* Store into fifoaddr address in musb units (8 bytes)

[RESEND PATCH 07/16] usb: musb: Fix transmission of bigger buffers

[Pali Rohár]

If udc_endpoint_write() was called with bigger payload which does not fit
into one USB packet it needs to be transmitted in more USB packets. First
packet is transmitted by udc_endpoint_write() call itself and other packets
are put into waiting queue.

Implement function musb_peri_tx() which transmit checks when endpoints are
ready and continue transmitting of waiting queue.

This patch fixes sending e.g. output of printenv command over usbtty serial
console.

[RESEND PATCH 08/16] usb: musb: Fix receiving of bigger buffers

[Pali Rohár]

If musb_peri_rx_ep() was called to processed received HW buffer but U-Boot
cannot read it yet (e.g. because U-Boot SW buffer is full) then interrupt
was marked as processed but HW buffer stayed unprocessed.

U-Boot tried to process this buffer again when it receive interrupt again,
but it can receive it only when sender (host) send a new data. As sender
(host) is not going to send a new data until U-Boot process current data
this issue caused a deadlock in case sender (host) is emitting data faster
than U-Boot can process it.

Reading musb intrrx register automatically clears this register and mark
interrupt as processed. So to prevent marking interrupt in U-Boot as
processed and a new variable pending_intrrx which would contain unprocessed
bits of intrrx register.

And as a second step, every time when musb_peri_rx_ep() is called and there
are waiting data to be processed (signaled by MUSB_RXCSR_RXPKTRDY) either
acknowledge sender (via musb_peri_rx_ack()) that whole HW buffer was
processed or set corresponding bit in pending_intrrx that HW buffer was not
fully processed yet and next iteration is required after U-Boot allocate
space for reading HW buffer.

This patch fixes receiving large usb buffers, e.g. file transfer via Kermit
protocol implemented by 'loadb' U-Boot command over usbtty serial console.

[RESEND PATCH 09/16] usb: musb: Fix handling interrupts for EP0 and SET ADDRESS commmand

[Pali Rohár]

Interrupt for EP0 is indicated in intrtx register via first bit. It is set
for both RX and TX. First bit in intrrx register is reserved and not set.

So remove calling musb_peri_ep0() function at every iteration of udc_irq()
and musb_peri_rx() and call it only from musb_peri_tx() when correct
interrupt bit in initrtx it set.

Address from SET ADDRESS command must be set to faddr register only after
acknowledging SERV_RXPKTRDY followed by received EP0 interrupt. So prior
calling musb_peri_ep0_set_address() check for EP0 interrupt instead of
(incorrect) MUSB_INTR_SOF interrupt.

This patch fixes issue that host (computer) cannot register U-Boot USB
device and failing with errors:

    usb 1-1: new full-speed USB device number 86 using xhci_hcd
    usb 1-1: Device not responding to setup address.
    usb 1-1: Device not responding to setup address.
    usb 1-1: device not accepting address 86, error -71

U-Boot was writing address to faddr register too early and did not wait for
correct interrupt after which should update address.

[RESEND PATCH 10/16] usb: musb: Ensure that we set musb dynamic FIFO buffer for every endpoint

[Pali Rohár]

If we do not set FIFO buffer address and size for some endpoint which is in
use then default address 0x0 would be used which is in conflict with FIFO
buffer for endpoint 0 which is at fixed address 0x0. Sharing address space
between more endpoint cause data loss and unexpected errors.

This patch is fixing transmission of characters over usbtty serial console
and allow using of usbtty for debugging purposes on Nokia N900.

Function lowlevel_init() is called only from cpu_init_crit() and this
function is wrapped into #if .. #endif section. So compile also
lowlevel_init() function under same #if condition.

Entry 'lowlevel_init' is defined 3 lines below and is available only
when !CONFIG_SKIP_LOWLEVEL_INIT && !CONFIG_SKIP_LOWLEVEL_INIT_ONLY.

Few lines above is code which copies DPLL code into SRAM and this code
ends at address where 'lowlevel_init' entry starts.

Entry 'cpy_clk_code' is compiled also when CONFIG_SKIP_LOWLEVEL_INIT is
defined, therefore it is required to define label which is outside of
the #if code defined below and ends after the 'go_to_speed' code.

So I defined a new 'go_to_speed_end' label to allow compiling
'cpy_clk_code' entry when CONFIG_SKIP_LOWLEVEL_INIT is defined.

Can you add exactly this description to the commit message -- the change 
isn't immediately obviously, collect the RBs and resend the patchset, so 
it can be picked ?

[Pali Rohár]

Function s_init() is called only from lowlevel_init(). So compile it only
when function lowlevel_init() is compiled.

[RESEND PATCH 14/16] Nokia RX-51: Remove function set_muxconf_regs()

[Pali Rohár]

This function is not used and was never called.

This board contains '#define CONFIG_SKIP_LOWLEVEL_INIT' because X-Loader
set everything up, including MUX configuration.

Also this MUX configuration is incorrect and does not match hardware.

So remove this dead, unused and broken code.

This change will decrease size of U-Boot binary.

[RESEND PATCH 16/16] Nokia RX-51: Enable usbtty serial console by default

[Pali Rohár]

Now when usbtty serial console is fixed in U-Boot enable CONFIG_USB_TTY for
Nokia RX-51 board by default.

Fix also USB product id as U-Boot ignores CONFIG_USBD_PRODUCTID macro and
include U-Boot string into USB product name to indicate usage of U-Boot.

CONFIG_CONSOLE_MUX is already used and U-Boot console is available for
all in/out devices. Therefore there is no need to have separate commands
'run sercon', 'run usbcon' and 'run vgacon', so remove them.

As space for U-Boot is limited to 256kB, disable some other unused options
so CONFIG_USB_TTY can be enabled.

Nokia RX-51 does not have easily accessible UART serial console so the only
option for easy debugging is to use device's keyboard+screen or this usbtty
serial console over USB.

Thanks for the series.

You may want to avoid cc-ing the Leste list, as it complains about too
many recipients and bounces.

[RESEND v2 PATCH 00/16] Nokia RX-51: Fix USB TTY console and enable it

[Pali Rohár]

    Resended v2 patch series with fixed commit messages

This patch series fix usbtty code (serial console via USB peripheral
mode), fix underlying musb peripheral code, fix compilation of
CONFIG_USB_DEVICE (used by usbtty), remove unused Nokia RX-51 code to
decrease size of U-Boot binary and finally enable usbtty serial console
for Nokia RX-51.

With this patch series debugging of Nokia RX-51 can be done also via USB
serial console.

It fixes also stability of musb code and allows usage of file transfers
via Kermit protocol on Nokia RX-51. Kermit file transfer via U-Boot loadb
command is stable on Nokia N900 and gives about 52kB/s transfer rate.

On computer this serial console is accessible via /dev/ttyACM0 device.

[RESEND v2 PATCH 01/16] serial: usbtty: Fix puts function

[Pali Rohár]

This function has incorrect implementation of prepending CR prior LF.
Without this patch it prepended CR prior whole string which is going to be
written and let LF without leading CR. Fix this issue by inserting CR at
correct place to make output on usbtty serial console more readable.

[RESEND v2 PATCH 02/16] serial: usbtty: Send urb data in correct order

[Pali Rohár]

Function next_urb() selects the last urb data buffer from linked list to
which next data from usbtty's puts function should be appended.

But to check if TX data still exists it is needed to look at the first urb
data buffer from linked list. So check for endpoint->tx_urb (first from the
linked list) instead of current_urb (the last from the linked list).

Successful call to udc_endpoint_write() may invalidate active urb and
allocate new urb in queue which invalidates pointer returned by next_urb()
function.

So call next_urb() prior putting data into urb buffer and call it every
time after using udc_endpoint_write() function to prevent sending data from
usbtty's puts function in incorrect order.

This patch fixes issue that usbtty code does not transmit data when they
are waiting in the tx queue.

[RESEND v2 PATCH 03/16] usb: musb: Fix compilation of gadget code

[Pali Rohár]

musb udc code depends on usb gadget code provided by CONFIG_USB_DEVICE as
defined in drivers/usb/gadget/Makefile. But this Makefile is not included
into U-Boot build when CONFIG_USB_GADGET is not set. As CONFIG_USB_DEVICE
cannot be enabled together with CONFIG_USB_GADGET it means that dependency
for musb udc code is not compiled during build. Fix it by including
drivers/usb/gadget dependency also when CONFIG_USB_DEVICE is set.

This patch fixes compile errors:

Without this patch clearing was done only when U-Boot was compiled with
MUSB Host Controller. But clearing of data toggle bit is needed also for
MUSB Device Controller otherwise Device Controller does not work correctly.

[RESEND v2 PATCH 05/16] usb: musb: Fix configuring FIFO for endpoints

[Pali Rohár]

This patch fixes configuring FIFOs for one-directional endpoints which have
only one queue (either RX or TX, but noth both).

Size of FIFO buffer is 2^(idx+3) bytes and starting address is 2^(addr+3).
Moreover first 64 bytes are reserved for EP0.

Without this patch if FIFO size specified by caller was zero then idx was
incorrectly calculated (expr. ffs(0)-1) and size overflowed in fifosz
register. This register uses has only 4 bits for FIFO size. Moreover
specifying zero buffer size is not possible (with idx=0 is minimal buffer
size 8 bytes).

So even for one-directional endpoints we need to correctly specify both
(RX and TX) FIFO buffer sizes and its addresses.

This patch is fixing calculation of start address and buffer size to
minimal value and ensures that it would not overlap with buffer reserved
for EP0.

This issue caused loose of packets on USB bus in both directions and
basically usbtty was unusable.

[RESEND v2 PATCH 07/16] usb: musb: Fix transmission of bigger buffers

[Pali Rohár]

If udc_endpoint_write() was called with bigger payload which does not fit
into one USB packet it is needed to transmit payload in more USB packets.
First packet is transmitted by udc_endpoint_write() call itself and other
packets are put into waiting queue.

Implement function musb_peri_tx() which checks if endpoints are ready for
transmit and continue transmission of waiting queue.

This patch fixes sending big output from printenv command over usbtty
serial console.

[RESEND v2 PATCH 08/16] usb: musb: Fix receiving of bigger buffers

[Pali Rohár]

If musb_peri_rx_ep() was called to process received HW buffer but U-Boot
cannot read it yet (e.g. because U-Boot SW buffer is full) then interrupt
was marked as processed also when HW buffer stayed unprocessed.

U-Boot tried to process this buffer again when it received interrupt again,
but it can receive it only when sender (host) sends a new data. As sender
(host) is not going to send a new data until U-Boot process current data
this issue caused a deadlock in case sender (host) is emitting data faster
than U-Boot can process it.

Reading musb intrrx register automatically clears this register and marks
interrupt as processed. So to prevent marking interrupt in U-Boot as
processed, adds a new variable pending_intrrx which would contain
unprocessed bits of intrrx register.

For a second step, every time when musb_peri_rx_ep() is called and there
are waiting data to be processed (signaled by MUSB_RXCSR_RXPKTRDY) either
acknowledge sender (via musb_peri_rx_ack()) that whole HW buffer was
processed or set corresponding bit in pending_intrrx that HW buffer was not
fully processed yet and next iteration is required after U-Boot allocates
space for reading HW buffer.

This patch fixes receiving large usb buffers, e.g. file transfer via Kermit
protocol implemented by 'loadb' U-Boot command over usbtty serial console.

[RESEND v2 PATCH 09/16] usb: musb: Fix handling interrupts for EP0 and SET ADDRESS commmand

[Pali Rohár]

Interrupt for EP0 is indicated in intrtx register via first bit. This bit
is set for both RX and TX despite register has only TX in its name. First
bit in intrrx register is reserved, not used and never set.

So remove calling musb_peri_ep0() function at every iteration of udc_irq()
and musb_peri_rx() and call it only from musb_peri_tx() when correct
interrupt bit in initrtx it set.

Address from SET ADDRESS command must be set to faddr register only after
acknowledging SERV_RXPKTRDY followed by received EP0 interrupt. So prior
calling musb_peri_ep0_set_address() check for EP0 interrupt instead of
(incorrect) MUSB_INTR_SOF interrupt.

This patch fixes issue that host (computer) cannot register U-Boot USB
device and is failing with errors:

    usb 1-1: new full-speed USB device number 86 using xhci_hcd
    usb 1-1: Device not responding to setup address.
    usb 1-1: Device not responding to setup address.
    usb 1-1: device not accepting address 86, error -71

U-Boot was writing address to faddr register too early and did not wait for
correct interrupt after which should update address.

[RESEND v2 PATCH 10/16] usb: musb: Ensure that we set musb dynamic FIFO buffer for every endpoint

[Pali Rohár]

If we do not set FIFO buffer address and size for some endpoint which is in
use then default programmed address 0x0 would be used which is in conflict
with address of FIFO buffer for endpoint 0. Moreover address of FIFO buffer
for endpoint 0 cannot be programmed, it is fixed to 0x0. Sharing address
space between more endpoints cause data loss and unexpected errors.

This patch is fixing transmission of characters over usbtty serial console
and allows using of usbtty for debugging purposes on Nokia N900.

go_to_speed_end at the place where go_to_speed code ends.

[RESEND v2 PATCH 16/16] Nokia RX-51: Enable usbtty serial console by default

[Pali Rohár]

Now when usbtty serial console is fixed in U-Boot enable CONFIG_USB_TTY for
Nokia RX-51 board by default.

Fix also USB product id as U-Boot ignores CONFIG_USBD_PRODUCTID macro and
include U-Boot string into USB product name to indicate usage of U-Boot.

CONFIG_CONSOLE_MUX is already used and U-Boot console is available for
all in/out devices. Therefore there is no need to have separate commands
'run sercon', 'run usbcon' and 'run vgacon', so remove them.

As space for U-Boot is limited to 256kB, disable some other unused options
so CONFIG_USB_TTY can be enabled.

Nokia RX-51 does not have easily accessible UART serial console so the only
option for easy debugging is to use device's keyboard+screen or this usbtty
serial console over USB.

I've integrated your patchset and now it turns out that the u-boot size
is too big:

Ah :-(
In November when I sent these patches, U-Boot binary was smaller.

Yes, memory for U-Boot is limited. It is needed to decrease size of
U-Boot binary and then it will work.

I will try to look at it later and find some dead code which can be
commented or removed to decrease binary size...

If you have an idea what increased U-Boot side it could help.

Just a quick test, could you try to add

CONFIG_OPTIMIZE_INLINING=y

into configs/nokia_rx51_defconfig file, if it helps?

They are working fine on my two testes machines. I do not have this
problem which Lukasz described. Otherwise I would not send patches to
mailing list for upstream. Also I have tested CONFIG_OPTIMIZE_INLINING
and it decreased size of u-boot binary on my machine.

But I already figured out that "working on my machine" does not mean
that it would also on other machines... In past I hit compiler bugs
which caused that on my machine gcc compiled code correctly but on other
machine with older (buggy) gcc code was compiled incorrectly and result
of computation was incorrect.

That is why I'm asking if people who triggered mentioned issue can check
if proposed fix helps.

Btw, if I understood correctly without CONFIG_OPTIMIZE_INLINING U-Boot
redefine "inline" to "always inline". And with CONFIG_OPTIMIZE_INLINING
"inline" is "inline". From past I know that gcc is very smart and can
decide that it is better to ignore inlining some functions for -Os size
optimizations.

Lukasz, is CONFIG_OPTIMIZE_INLINING=y option fixing build for you?

Could you setup the CI environment and test your patchset with it?

It is documented in .azure-pipelines.yml.

Azure build takes not more than 3h for the whole test setup.
