  "message": "lib: sbi: Apply budget restriction when polling Zkr CSR state transition\n\nZkr architecture doesn\u0027t define a time limit on state transitions\nwhich results in hanging on unresponsive or event-driven platforms.\nTo prevent this, we need to limit polling iterations and fall back\nin case the budget is over, and stack guard keeps its initial value.\nThe budget is configurable with CONFIG_ZKR_POLL_BUDGET, defaulting\nto 1000 iterations. Successful reads do not consume a try.\n\nSigned-off-by: Evgeny Voevodin \u003cevvoevod@tenstorrent.com\u003e\nReviewed-by: Anup Patel \u003canup@brainfault.org\u003e\nLink: https://lore.kernel.org/r/20260519225014.244672-1-evvoevod@tenstorrent.com\nSigned-off-by: Anup Patel \u003canup@brainfault.org\u003e\n",
