J. Nick Koston fe759e613e Merge remote-tracking branch 'upstream/esp32-sram1-as-iram' into integration 2026-03-16 14:56:49 -10:00
J. Nick Koston 9c81c0ab53 [esp32] Add sram1_as_iram option for +40KB IRAM on original ESP32 
Add a new `sram1_as_iram` option under `esp32 > framework > advanced`
that enables CONFIG_ESP_SYSTEM_ESP32_SRAM1_REGION_AS_IRAM, reclaiming
40KB of SRAM1 memory as additional IRAM on the original ESP32.

This requires a bootloader from ESP-IDF v5.1 or later. USB flashing
updates the bootloader automatically, but OTA does not. At boot,
ESPHome now detects the bootloader version and suggests enabling
this option when the bootloader is compatible.

J. Nick Koston 8e8faaa983 Merge remote-tracking branch 'upstream-ssh/api-overflow-buffer-cleanup' into integration 2026-03-16 13:11:13 -10:00
J. Nick Koston 1ecbd28742 Address review: restore queue-full log, fix power-of-2 comment 
- Add HELPER_LOG when overflow buffer is full and connection is dropped
- Clarify comment: defaults are power of 2 (not a requirement for users)
 2026-03-16 13:09:41 -10:00
J. Nick Koston 61cc3022cb Address review: save errno before use, fix docs, add missing include 
- Save errno into local before check_socket_write_err_ and HELPER_LOG
  to avoid potential clobbering between reads
- Update try_drain() doc: 0 means all-drained or no-progress (callers
  only act on -1)
- Include socket/headers.h explicitly for struct iovec

J. Nick Koston 3ac6eb0f5a Address review: only log hard errors, fix try_drain doc comments 
- Move HELPER_LOG after errno check so transient WOULD_BLOCK doesn't
  spam very-verbose logs during normal backpressure
- Fix try_drain() docstring: -1 can be EWOULDBLOCK or hard error
  (caller distinguishes via errno), 0 means no progress (not would-block)

J. Nick Koston 9f774b3827 Inline empty() fast path, out-of-line drain+error handling 
Keep the cheap overflow_buf_.empty() check inline at all call sites.
Move try_drain + HELPER_LOG + error handling into a single out-of-line
drain_overflow_and_handle_errors_() used by both write_raw_ and the
subclass loop() methods. Eliminates the duplicated drain logic.

Only one call site remains after tail-call restructure, so inline it.
Add [[unlikely]]/[[likely]] hints for overflow and error paths.

J. Nick Koston 7846c42730 Rename base loop() to try_drain_overflow_buffer_() inline helper 
The base class loop() only drained the overflow buffer. Rename to
make intent clear and inline it so the compiler can optimize across
the call boundary. Make loop() pure virtual since subclasses always
override it.

J. Nick Koston c03dd86796 Replace modulo with compare-and-reset for circular buffer indices 
Modulo generates a full division on ESP8266 since API_MAX_SEND_QUEUE
is not a power of 2. Use increment + compare instead.

J. Nick Koston 0eed9e8eb6 [api] Extract overflow buffer from frame helper into APIOverflowBuffer 
The TCP send overflow buffer code was embedded directly in
APIFrameHelper, making it appear to be part of the primary send path.
In reality, it is rarely used in production — only when the kernel TCP
send buffer is full due to a slow client, congested network, or heavy
logging. Extract it into a dedicated APIOverflowBuffer class with clear
documentation about its purpose and usage frequency.
