EP0 - packetsize of 8 does not work, this means that PIO cannot be used for IN (transmit). ++ * DMA must be used. Only 16, 32 and 64 are usable. ++ * ++ * Update: even though we couldn't program the endpoint size to 8, we just set it to 8 in the ++ * device descriptor and things work ok. This works and we don't need or use DMA for either ++ * direction for EP0. ++ * ++ * 2. For each BULK transfer the first N packets must be sent with the full packetsize and the ++ * last must be sent as a short packet. The packetsize must be set before enabling the DMA. ++ * ++ * 3. For IN endpoints an interrupt will be generated for EVERY IN packet including ones that ++ * will be NAK'd. To reduce overhead the interrupt should only be enabled when there is data ++ * being sent and we need to know when it has been sent. ++ * ++ * Update: for new silicon this is not true, the UDC will interrupt less often and will NAK ++ * until the interrupt is cleared. ++ * ++ * 4. The AU1x00 auto-acks many setup commands and is very sensitive to latency of the irq ++ * handler processing the interrupt and clearing the ep0 fifo. Like the pxa we need to spool the ++ * requests and process later when we receive a request for data. There is a special test in ++ * the bulk data receive handler to check if there are spooled requests to process. ++ * ++ * Update: this has been mostly mitigated by reducing all upper layer processing in recv_setup, ++ * event_irq etc so that they complete in less than a milli-second. This simplifies things and ++ * we can now pass UUT tests. ++ * ++ * 5. There is a time sensitive problem in au_in_epn(). Without a udelay(8) sending large ++ * packets will eventually stall interrupts. ++ * ++ * Update: this is not required for new silicon. ++ * ++ * 6. When receiving data (Bulk OUT) the UDC will not start NAKing until and unless the receive ++ * FIFO is full. This means that there is no reliable way to determine the end of one packet and ++ * the beginning of the next if there is any undue latency in handling the interrupt for the ++ * first packet. ++ * ++ * The Belcarra Windows and Macintosh network class drivers have an option that can be used ++ * to pad all outgoing packets to a multiple of 8 bytes. This helps eliminate this problem. ++ * ++ * Update: this is not a problem with new silicon, it NAK's until the interrupt is cleared. ++ * ++ * 8. The original AU1x00 UDC generated an interrupt for EVERY IN packet. If we do not have ++ * any data we need to disable the interrupt for the endpoint to eliminate the overhead ++ * for processing them. The interrupt must be re-enabled when DMA is finished and we ++ * actually want to know that the endpoint has finished. ++ * ++ * Leaving the interrupt enabled also interfers with the DMA process. It is not apparant ++ * why. ++ * ++ * Update: This has been fixed on the new silicon but it doesn't hurt to continue to do this. ++ * ++ * 9. The DMA functions replace the equivalent routines in au1100_dma.h except that they pass ++ * the actual struct dma_chan pointer instead of the channel number. The bounds checking and ++ * table lookup to derive this information amounts to a substantial increase in code size and ++ * latency which can simply be avoided by using the structure address directly and/or doing the ++ * equivalent i/o directly. ++ */ ++ ++ ++#include <udc.h> ++#include "au1x00.h" ++ ++#include <asm/io.h> ++#include <asm/au1000.h> ++#include <asm/au1000_dma.h> ++#include <asm/mipsregs.h> ++ ++ ++#ifdef CONFIG_MIPS_FREEHAND ++#include <linux/i2c.h> ++#include <linux/sensors.h> /* for reading serial number */ ++#endif ++ ++MODULE_AUTHOR ("sl@belcarra.com, tbr@belcarra.com"); ++MODULE_DESCRIPTION ("USB Device AU1x00 Bus Interface"); ++#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,4,17) ++MODULE_LICENSE("GPL"); ++#endif ++USBD_MODULE_INFO ("au1x00_bi 2.0-beta"); ++const char *usbd_bi_module_info(void) ++{ return __usbd_module_info; } ++ ++#undef CHECK_LATENCY ++#undef RECORD_LATENCY ++#undef MAX_INTR_LOOP_STATS 10 ++#if defined(MAX_INTR_LOOP_STATS) ++static u32 interrupt_loop_stats[MAX_INTR_LOOP_STATS+1]; ++#endif ++#ifdef RECORD_LATENCY ++#define CP0_COUNTS 50 ++u32 cp0_counts[CP0_COUNTS]; ++u32 cp0_record; ++#endif ++u32 cp0_count; ++unsigned int udc_interrupts; ++unsigned int udc_saw_bus_activity; ++int au_halt_dma_expired; ++u32 au1x00_new_silicon; ++u32 au1x00_inten; ++static int udc_connected_status; ++ ++__u8 au1x00_config_bulk[25] = { ++ 0x04, (USB_ENDPOINT_CONTROL << 4) | (EP0_PACKETSIZE & 0x380) >> 7, // 1 ++ (EP0_PACKETSIZE & 0x7F) << 1, 0x00, 0x00, ++ 0x24, (USB_ENDPOINT_BULK << 4) | USB_DIR_IN | (MAX_EPN_PACKET_SIZE & 0x380) >> 7, // 6 ++ (MAX_EPN_PACKET_SIZE & 0x7F) << 1, 0x00, 0x02, ++ 0x34, (USB_ENDPOINT_BULK << 4) | USB_DIR_IN | (MAX_EPN_PACKET_SIZE & 0x380) >> 7, // 11 ++ (MAX_EPN_PACKET_SIZE & 0x7F) << 1, 0x00, 0x03, ++ 0x44, (USB_ENDPOINT_BULK << 4) | USB_DIR_OUT | (MAX_EPN_PACKET_SIZE & 0x380) >> 7, // 16 ++ (MAX_EPN_PACKET_SIZE & 0x7F) << 1, 0x00, 0x04, ++ 0x54, (USB_ENDPOINT_BULK << 4) | USB_DIR_OUT | (MAX_EPN_PACKET_SIZE & 0x380) >> 7, // 21 ++ (MAX_EPN_PACKET_SIZE & 0x7F) << 1, 0x00, 0x05, ++}; ++ ++/* ********************************************************************************************* */ ++/* Note - The endpoints names are confusing.
