The wasm front end already tracked panel refreshes; make the counter
unconditional and alias it onto the machine so native front ends can
redraw on refresh instead of on a timer.
Report SOF and serial-in-empty as always pending and route the peripheral
IRQ through the interrupt matrix so the ESP-IDF console driver progresses.
Merge emulator stdout into serial.log so crash output lands in one place.
Ports the ESP32 Wi-Fi emulation (esp32c3_wifi, esp32_wifi_ap, esp32_wlan_*)
from the lcgamboa/PICSimLab QEMU fork and integrates it behind the
esp32c3_wifi NIC model, plus the supporting radio peripherals
(ANA/PHYA/FE/PWR manager).
- Exposes an open SSID 'qemu' bridged to the host via QEMU user-mode NAT
(libslirp, now enabled in the native build).
- Adds ESP-IDF 5.5 compatibility fixes: channel resolution from the
beacon DS Parameter Set IE / AP lookup, persistent SYSCON register
backing (phy_module_has_clock_bits), DMA inlink/outlink descriptor
mirroring, RX descriptor ring reset on item.next==0, and descriptor
ownership/length semantics.
- xteink-emu now starts with -nic user,model=esp32c3_wifi and synthesizes
an eFuse image with a fixed guest MAC.
Verified against a stock Arduino-ESP32 sketch: scans, finds 'qemu',
associates, gets DHCP 192.168.4.15, and completes an outbound TCP
connection. Unmodified CrossPoint firmware still needs the power-button
hold during boot (tracked separately).
The reader draws a crisp BW page, then a 4-level grayscale antialiasing
pass with inverted plane polarity (white = level 0 = both planes clear)
and near-empty planes. The old model replaced the whole frame with those
planes, wiping the page to an inverted muddle.
Model it as e-ink actually behaves: keep a persistent surface, detect
grayscale vs BW by DTM2's set-fraction (background is the white
majority), and in grayscale treat level 0 as no-drive (keep pixel) so
only the sparse antialiased edges repaint over the retained BW page. BW
refreshes still repaint every pixel. Reader text now renders sharp.
ssi-sd now enters token mode as it returns the final R1 byte, so the
write-data token that immediately follows is not discarded. SPI CMD13
returns the internal sd_r1 response (upstream fix) instead of sd_r2_s,
which the adapter converts to the two-byte SPI R2 status; this stops the
repeated "Unexpected response to cmd 13" loop on guest status polls.
Drops the experimental store-TB TCI forcing and sd-watch OOB logging now
that the raw FAT32 image path is stable.
Diagnostic: routes store-containing TBs through TCI and logs out-of-bounds
guest stores to isolate the SdSpiCard corruption. Also carries the FAT32
vvfat root/cluster fixes and ssi-sd command framing. Squash/split before
upstreaming.
